1. INTRODUCTION
Heos is a control system for the complete management of showcases or cold rooms in which the compressor (variable speed or on/off ) is cooled by a water loop.
The control board is ready for DIN rail assembly, is fi tted with plug-in screw terminals and comes with a built-in electronic expansion valve driver.
In order to manage multiplexed showcases, Heos can manage a local
Master-Slave network comprising a maximum of 6 units (1 Master and 5
Slave). Each controller can be fi tted with its own display (PLD) and/or user terminal (pGDe), for service or commissioning.
Main features:
• board with built-in driver for CAREL single-pole valve;
• modulating management of cooling capacity by inverter on BLDC compressor;
• stand-alone or multi-evaporator management;
• automatic balancing of cooling capacity in multi-evaporator confi guration;
• COP calculation and management;
• advanced superheat control with protection against low superheat
(LowSH), low evaporation temperature (LOP), high evaporation temperature (MOP) and low suction temperature (LSA);
• defrosts can be activated from the keypad, digital input, via network from the Master, or supervisor;
• various types of defrost available: electric heater, reverse cycle, hot gas;
• smart defrost functions;
• coordination of network defrosts;
• management of lights and curtains;
• anti-sweat heater modulation;
• evaporator fan speed modulation;
• possibility to display and set Slave parameters from the Master;
• sharing of one or more network probes (e.g. network pressure probe);

There are two possible showcase/cold/room confi gurations. The fi rst involves the various units being fi tted individually with their own compressor and condenser, meaning the showcase is completely independent, and shares the cooling water loop with the rest of the system. In the second case, the condenser is shared and consequently the
Slave showcases are only fi tted with the evaporator and corresponding electronic expansion valve, while the compressor is controlled by the
Master board.
The system confi gurations can be set from a terminal (pGDe) as illustrated in the chapter on Commissioning; while on the showcase itself a PLD is normally used to display the temperature and any alarm signals.
Defrosts can be coordinated via the pLAN that controls a maximum of 6 units, or alternatively by the supervisor
1. Stand-alone confi guration
In this case, each showcase/cold room has its own compressor, controlled by the corresponding board, which manages all system devices
(expansion valve, showcase temperature control, alarms….).
The Master/Slave network is used for to coordinate defrosts, lights and curtain switch; otherwise these functions must be managed by the supervisor.
BMS
Waterloop
ENG
2. Multi-evaporator Master/ Slave network
The Master controller manages the compressor and coordinates the functions of the 5 Slave controllers connected via the pLAN. Each Slave controller manages the individual showcase and has a PLD user terminal for temperature monitoring. Each controller, both Master and Slave, is connected to the supervisor network. The Master only shares the evaporation pressure, and not the corresponding temperature.

2.9 Installation
For installation, proceed as follows, with reference to the wiring diagrams:
• before performing any operations on the control board, disconnect the main power supply by turning the main switch in the electrical panel OFF.
• avoid touching the control board with bare hands, as any electrostatic discharges may damage the electronic components;
• suitable electrical protection must be ensured by the manufacturer of the showcase or by appropriate installation of the controller;
• for safety devices (e.g.: residual current circuit breakers), comply with the following requirements:
IEC 60364-4-41
-
Normative in vigore nel paese standards in force in the country where the product is installed
connection technical requirements established by the electricity company
• if use a B or B+ residual current circuit breaker when the compressors are controlled by inverter; these protection devices must always be installed always upstream of the AC/A/F (see the fi gure below)

The diff erential protection device, inside a TT,TN network, can be used for several showcases as shown in the example below.
Fig. 2.r
Attention: the size and the tripping current of the diff erential switch must be properly sized in accordance with the network type (TT,
TN-C, TN-S) and the number of inverters connected.
• connect any digital inputs, Lmax=10 m;
• connect the temperature and pressure probe, Lmax=10 m;
• connect the electronic expansion valve cable to connector J12;
• connect the inverter serial communication cable (if used) to terminal
J11;
• connect the optional PGDe terminal (needed for commissioning) to connector J15;
• connect the optional PLD terminal to connector J10;
• connect power supply to controller and the inverter, if used;
• program the controller using the guided commissioning procedure: see the chapter on Commissioning”.
• Program the individual controllers using the Wizard (also used to assign the pLAN address) and then connect the controllers in the same pLAN
Master/Slave group together, using connector J14. For connection, use a shielded cable and make sure that the maximum distance between consecutive controllers is 100 m (minimum cable size AWG22);
• connect the electrical loads to the relay outputs only after having programmed the controller. Always carefully evaluate the maximum capacity of the output relays, as specifi ed in the Technical specifi cations;
• connect the supervisor serial line to the card inserted on connector
J13.
Important: avoid installing the controllers in environments with the following characteristics:
• relative humidity greater than 90% or with condensation;
• strong vibrations or knocks;
• exposure to water sprays;
• exposure to aggressive and polluting atmospheres (e.g.: sulphur and ammonia fumes, saline mist, smoke) to avoid corrosion and/or oxidation;
• strong magnetic and/or radio frequency interference (therefore avoid installing the devices near transmitting antennae);
• exposure of the controllers to direct sunlight and to the elements in general.
Important: the following warnings must be observed when connecting the controllers:
• incorrect power connections may seriously damage the controller;
• use cable ends suitable for the corresponding terminals. Loosen each screw and insert the cable ends, then tighten the screws and gently
• separate as much as possible the probe and digital input cables from cables to inductive loads and power cables, so as to avoid possible electromagnetic disturbance. Never run power cables (including the electrical panel cables) and probe signal cables in the same conduits;
• do not run probe signal cables in the immediate vicinity of power devices (contactors, circuit breakers, etc.);
• reduce the path of probe cables as much as possible, and avoid spiral paths that enclose power devices.
Important: Class A software: the safety devices providing overload and high pressure protection must control the compressor directly, and consequently need to be wired in series with compressor contactor control signal.
Note: when connecting the serial network:
• connect the shield to the GND terminals on all controllers;
• do not earth the shield on the electrical panel;
• use a shielded twisted cable AWG20-22 (e.g. Belden 8761 or, in the event of particularly demanding environments from a point of view of electromagnetic disturbance, Belden 3106A);
• For the supervisor serial network (J13): connect a 120 Ω terminating resistor between the Tx/Rx+ and Tx/Rx- terminals on the last controller in the network (the one furthest away from the supervisor). Do connect any resistors to the pLAN Master/Slave network connectors (J14).

5. STARTUP
5.1 Guided commissioning procedure
The Heos controllers can be setup the fi rst time from the pGDe user terminal connected to J15. After programming, the terminal can be removed or remain connected.
If the controller has not yet been confi gured, the user terminal shows the language selection and than the fi rst screen in a guided confi guration procedure, called the “wizard”. Otherwise, the same menu can be accessed from branch.
E.Confi guration>>f.default
.
The main parameters needed for general confi guration are shown one at a time. The wizard screens are all numbered in the top right corner; the following explanations refer to this number. To go from one screen to the next press , while to return to previous screen press .
Screen WZ09: set point and virtual probe composition. This screen is used to set the control set point and the weight of the outlet and intake temperature probes in the average for calculating the control temperature. When the parameter is set to 0%, the virtual probe coincides with the outlet probe, if set to 100% the virtual probe coincides with the intake probe.
Important: at the end of the procedure, exit by powering the unit OFF, after having exited screen WZ19 by pressing .
Screen WZ01: this shows the code of the application loaded on the controller (FLSTDmWL0M) and the revision. Pressing starts the guided procedure.
x.x xxx
Screen WZ02: select multi-evaporator/individual compressor confi guration. A group of controllers is called “multi-evaporator” when multiple controllers (up to 6) are connected in a Master/Slave network, and share the same compressor, controlled by the Master. If setting “Y” for the parameter on this screen, the unit will be part of a multi-evaporator group. Setting “NO”, the unit is confi gured as stand-alone or part of a
Master/Slave group with an individual compressor on each unit.
Screen WZ03 : unit address. The unit can be confi gured as the Master or as one of the Slaves, setting the parameter to MASTER or SLAVE1, SLAVE2,
… SLAVE 5. Setting this parameter also sets the controller pLAN address as a consequence: 1 for the Master, 2 for Slave 1, 3 for Slave 2, and so on up to 6 for Slave 5.
Screen WZ04: this is only shown if the controller is set as the Master and the multi-evaporator confi guration has been selected. This specifi es the number of evaporators connected to the Master. The default value is the number of Slaves connected.
Screen WZ05: this is only shown if the controller is set as the Master and the multi-evaporator confi guration has not been selected. specifi es the number of Slaves connected to the Master.
Screen WZ06: evaporator capacity. If the unit is confi gured as part of a multi-evaporator group, this screen is used to set the rated evaporator cooling capacity. This data is used to adjust the compressor speed based on demand from the various units served.
Screen WZ07: select type of unit. The type of unit can be selected as
SHOWCASE or COLD ROOM. If COLD ROOM is selected, other parameters are proposed: the position of the door switch and enable/disable the three temperature probes: outlet, defrost and intake.
Screen WZ08: select type of unit of measure (SI or Imperial) for temperature and pressure.
Screen WZ10: select type of compressor: BLDC, ON/OFF (single) or ON/
OFF (multiple).
Screen WZ11: select the digital input for multi compressors.
Screen WZ12: select compressor and inverter programming. For the
Compressor parameter, any one of the compressors managed by
Heos can be selected. Under the type of compressor, if the inverter is connected and on, the model of Power+ can be read. If the inverter is off or not connected, the last row of the screen displays the message
Power+ not connected. After having confi rmed the type of compressor, if communication with the inverter is active, Write parameters is displayed; choosing Y starts writing some of the parameters to the inverter, so as to ensure correct operation with the selected compressor. During the write procedure, the display shows Installing parameters…, replaced by a confi rmation message when the write procedure has ended. If the control is fi tted on a Slave on a multi-evaporator unit, this screen is not displayed.

Active probes (voltage or current) can be powered directly by Heos (see the chapter on connections). For all these probes, the range of measurement needs to be confi gured on the corresponding screen.
Heos can modify the values read by the probes by applying a settable off set directly in the screen used to associate the function to the input.
Serial probes cannot be calibrated, while probes that are shared with the Master (such as the common pressure probe for multi-evaporator systems) are calibrated on the Master. Only one pressure probe can be shared across the Master/Slave network in multi-evaporator mode, and must only be connected to the Master. Simply correctly confi gure the probe in the corresponding screen and then on the Slaves, in the same screen, select the “shared” probe option. In this way, the Slaves will automatically look for the pressure value shared by the Master and use this to calculate local superheat. This saves the cost of installing a pressure probe on each evaporator, assuming that the pressure drop on of line in the corresponding section is negligible.
The room temperature and humidity probes must not be positioned too far from the corresponding showcases. At times it is better to install more than one if the supermarket is divided into zones with diff erent temperature and humidity (frozen foods, meat, fruit and vegetables, etc.): glass temperature probe: NTC060WG00. The glass temperature probe is connected at the coldest point of the glass on the showcase, so as to optimise operation of the anti-sweat device (heaters or fans). See instruction sheet +050002005.
Master/Slave system (see functional diagram for stand-alone confi guration on page 3)
Up to 6 units can be connected together in a Master/Slave confi guration, where the Master synchronises the defrosts and the night/day transition for the entire group, and shares the suction pressure reading.
Communication between units in the same Master/Slave group is managed over a pLAN sub-network connected to terminal J14 on each controller.
Multi-evaporator system (see functional diagram for multi-evaporator
Master/Slave network on page 13)
In a Master/Slave system, just one compressor can be used, connected to the Master, to serve the evaporators on the Slaves. This is called a multievaporator system. One condensing unit can be connected to up to six evaporators (including the Master). Each evaporating unit will be fi tted with a controller, electronic expansion valve, air temperature probes, refrigerant superheat temperature probe (evaporator outlet) and evaporator outlet pressure probe. On the controllers, the cooling capacity of each unit needs to be set (parameter PE2) and multi-evaporator mode must be activated on both the Master and the Slaves (parameter PE1 > 1). On multi-evaporator systems, the Master suction pressure probe reading can be shared and used to calculate the superheat on the Slaves (confi gured by default).
Heos manages four physical digital inputs, which can be selected as shown below. There is also the possibility to use a virtual digital input, propagated via pLAN from Master to Slaves. This is useful, for example, for a curtain switch, as the units can switch from daytime to night-time operation and vice-versa without needing additional wiring between the
Master and the Slaves. The virtual digital input can be set on the Master, using parameter A9, and will be propagated to the Slaves by selecting
“Virtual DI”.
For example, if there is a Heos confi gured as Master and another as Slave,
DI1 on the Master will be connected to the door switch, and its status will be shared with the Slave:
• on the Master, set parameter A9 to DI1;
• on the Slave, on the Door switch input confi guration screen, select
“Virtual DI”.

Functions available for the digital inputs
For each function, there is a confi guration screen used to associate it with an available digital input. The same screen is used to select the input confi guration (normally open or normally closed). The status (Open or
Closed) displayed is the eff ective position of the input, while the function is associated with the selected logic. When the input is in the physical status specifi ed as “normal” in the logic, the function is “Not active”, when the input is in the opposite physical status, the corresponding function is “Active”.

Activation of the input causes:

• activation of the buzzer
• activation of the alarm relays (if confi gured, see digital outputs);
• deactivation of the compressor.
Note: When the compressor is shut down due to a remote alarm the minimum compressor ON time (parameter c3) is ignored.
Remote alarm with activation delay
Operation of this alarm depends on the setting of parameter A7 (delay time for delayed remote alarm):
A7=0: signal only alarm on the display, normal operation of the controller is not aff ected (default);
A7≠0: alarm similar to the remote alarm (immediate), activation is delayed by the time set for A7.
Enable defrost
Used to disable any defrost calls. When the contact is open, all defrost calls are ignored. Parameter d5 can be used to delay activation.
Start network defrost
Closing the digital contact starts the defrost, if enabled. In the event of
Master/Slave network connection, if the controller is the Master, the defrost will be a network defrost (i.e. will also involve all the Slaves), while if it is a Slave, it will only be a local defrost. The defrost digital input can be used eff ectively to perform real time defrosts. Simply connect a timer to the multifunction digital input on the Master and use d5 to delay the defrosts on the various Slaves and thus avoid current overloads.

Door switch
With the door open (switch active) the following occur:
• Lights on
• Fans off
• The delayed alarm counter starts (parameter d8)
• The message “DOR” is shown on the PLD display
For stand-alone evaporator units:
• Compressor off (without deactivation ramp, cooling demand is not reset, but continues to be calculated)
For multi-evaporator units:
• Compressor cooling demand continues to be calculated, however the component relating to the unit with the door open is reset
• Expansion valve closed
When the door is closed:
• Lights off
• Fans on
For stand-alone evaporator units:
• The compressor is restarted as normal
For multi-evaporator units:
• The component of demand relating to the unit whose door was open is used again in the calculation
• The expansion valve resumes operation (pre-positioning as at start-up)
Note:
• when resuming control, the compressor protection times are observed;
• if the door remains open for a time greater than the value set for parameter d8, control is resumed in any case. The light remains on, the buzzer and the alarm relay are activated, and the temperature alarms are enabled, with the delay Ad.

Switches the controller off via the digital input. The PLD displays the value measured by the selected probe (parameter /t2) alternating with the message OFF; switch ON commands from the keypad or supervisor are ignored.
Note:
• if more than one input is confi gured as the remote ON/OFF, the off status of one any of these switches the controller OFF;
• the OFF control from digital input has priority over the keypad and the supervisor;
• if the controller remains OFF for longer than the value set for basic parameter (time between consecutive defrosts), when the controller is switched back on a defrost is performed.
Curtain/light switch
The curtain switch is used to control night/day status via a digital input.
When the switch is active (open if NC, closed if NO), the status is set to
NIGHT, when the switch is not active, the status is DAY.
• During Night status, the night-time set point Stn is used for control, calculated based on the set point St plus the off set defi ned by parameter r4 (Stn = St + r4). If r4 is negative, during Night status the eff ective set point is decreased from the Day set point.
• In addition, if necessary the control probe is changed based on the setting of parameter r6 (0 = virtual probe, 1= intake probe); the light is switched off .
• During Day status: normal operation resumes, set point = St, the virtual probe used as the control probe; the light output is activated.

During the day most of the load of the showcase is due to the warm air that enters from the outside and mixes with the cool air inside.
Control based on the intake probe, due to high temperature outside the showcase and the mixing of the air, may not manage to reach the set point. Displaying the intake temperature would show a temperature that is too high. Setting a set point that is too low for the intake probe Sr may cause the food to freeze. On the other hand, displaying the outlet temperature would show a temperature that is too low. Consequently, the display (on the PLD) of the control probe, set point or virtual probe can be confi gured using parameter /t2.

Temperature control of the refrigeration unit is managed using a proportional + integral (P+I) algorithm. Based on the diff erence between control temperature and set point (proportional error) and the trend in this diff erence over time (integral error), the controller varies the request for cooling capacity on a scale from 0 to 100%. Depending on the model of compressor installed, this percentage is converted to an operating speed, expressed in revolutions per second (rps).
To adapt control to the characteristics of the refrigeration unit, the proportional gain (Kp) and integral time (tI) can be adjusted.
Kp represents the percentage of increase in cooling request according to the deviation from the set point [%/°C], tI represents the time interval to evaluate the variation and the trend in the integral error. High values of
Kp lead to higher variations in request for the same variation in control temperature (Treg), high values of tI lead to smaller variations in request over time.

Night-time operation
During night-time operation, the curtain on the showcase is closed and consequently less cold inside air is mixed with warm outside air. The thermal load decreases. The temperature of the air that cools the produce is near the outlet temperature, and therefore to avoid excessively low temperatures and reduce energy consumption, the set point needs to be increased at night, by setting parameter r4. Parameter r6 can then be used to assign the virtual probe Sv or intake probe Sr as the control probe.
The change to night-time operation must be signalled externally. This is done using the curtain switch (set using the parameters relating to the digital inputs) or by setting time bands (S1…S3), or from the supervisor, or using a command from the Master via the Master/Slave network. Nighttime status is activated by the transition of the assigned digital input from
“Not active” to “Active”. Vice-versa, a transition from “Active” to “Not active” changes back to daytime status. If, when the digital input is active, the signal is sent to change to daytime status by the supervisor or one of the other possible sources, the controller switches to daytime status. In other words, none of the sources has higher priority than the others, rather the status depends on the most recent command.

Control off set with probe error (parameter r0)
By default, Heos uses the virtual probe Sv for control, that is, the weighted average of the outlet and intake probe (see parameter /4). If one of the two probes making up the virtual probe is broken or has an error, parameter r0 is used to continue normal control in controlled conditions, without the need for an immediate response by maintenance personnel.

The recommended value of r0 is the temperature diff erence between the outlet probe and intake probe reading in steady refrigeration unit operating conditions: r0 = Sr-Sm
The following two cases may occur: outlet probe Sm error: starts control based on the intake probe Sr alone, considering a new set point (St*) determined by the formula:
St* = St + r0 •

If night-time operation has been set with the intake probe as the control probe, the controller considers /4=100 and uses the outlet probe. The new set point becomes:
St* = St-r0
Note:
• if an error occurs on both probes, the controller switches to duty setting operation, see below.
Example: Sm fault in daytime operation, with /4=50, St=-4, Sr=0, Sm=-8, r0 (recommended) = 0-(-8) =8. Then the new control probe will be Sr with:
St*= -4+8 •(100-50)/100=0
If the fault is on Sr, the new control probe will be Sm with:

Duty setting operation (parameter c4)
Duty setting is a special function used to maintain control in emergency situations with errors in the temperature control probes, until a service callout is possible. In the event of a temperature probe error, Heos uses the other probe available and adjusts the set point according to the setting of parameter r0. In the event of errors on both probes, Heos switches to duty setting mode. The controller is activated at regular intervals, operating for a time equal to the value set for the duty setting parameter c4, and off for a time equal to c5. Compressor speed is fi xed, at the value set for cI3.

Multi-evaporator system control
Each evaporating unit has its own cooling capacity (parameter PE2).
Compressor speed is calculated based on the average between the diff erence between the control temperature and the set point on each unit, weighed according to the cooling capacity of each evaporator. If there are three evaporators, the total error E_TOT that the P+I control algorithm will use to calculate the output depends on the cooling capacities of the three units (PM, PS1, PS2).
The E_TOT calculated in this way is applied to a P+I algorithm so as to determine the required percentage of cooling capacity, which translates into the required compressor speed.
Superheat modulation (multi-evaporator)
On showcases where active, the superheat set point varies between the user setting (P3) and an off set (PE7) with P+I logic, so as to correctly manage the control temperature. As the control temperature approaches the set point, the superheat set point is increased, so as to further close the expansion valve. To activate this function, set the off set PE7 to a value greater than 0.
Duty setting with multi-evaporator
Activation of duty setting mode on the Master controller implies that the compressor management times set for the Master controller are also used by all the connected Slaves. The Slaves will activate and deactivate control of the expansion valve according to compressor operation (ON or OFF). If a Slave is in duty setting mode (due to a probe error), the proportional component corresponding to the unit with the error will be equal to the value of parameter cI3, weighted according to the cooling capacity (PE2).

The thermodynamic parameters and times are part of the Heos controller software: these are used to control the compressor, making sure that normal operating conditions are always within the limits set by the manufacturer. The electrical parameters are written in the Power+ inverter fi rmware: these are the parameters that allow the sensorless controller to eff ectively manage the compressor. Selecting the compressor involves confi guring all the thermodynamic parameters and times on the Heos controller; writing the parameters (last item on the screen) initialises the electrical parameters on Power+. Once the model has been selected and the parameters downloaded to Power+, no other compressor parameters are required to start the unit.
Envelope management
The envelope defi nes the operating range in which the compressor can safely work for an indefi nite time. This can be represented graphically by plotting several limits, inside which normal operating conditions need to be kept. The fi gure shows the envelope for the Toshiba DA series horizontal compressors.

The limits of the envelope consist of:
• Minimum and maximum condensing temperature
• Minimum and maximum evaporation temperature
• Minimum and maximum compression ratio (CR)
• Maximum compressor current draw
Normal operating conditions are defi ned by:
• Evaporation pressure (or saturated temperature)
• Condensing pressure (or saturated temperature)
• Discharge temperature
• Rotation speed (rps)
The form of the envelope may change according to compressor speed, and with this the normal operating conditions considered as being safe for the compressor. Consequently, a certain pair of operating pressures may be considered safe (within the envelope) at a certain speed, and unsafe (outside the envelope) at another speed.
With reference to the Toshiba envelope shown above: the conditions
Tcond = 40°C Tevap = -10°C are inside the envelope at a speed of 30 rps, but are outside at a speed of 15 rps.
The set point depends on the outside conditions (fl uid temperature at the heat exchangers) and on unit operation: compressor speed, expansion valve opening. Consequently, the set point can be shifted, increasing or decreasing the condensing and evaporation pressures by adjusting compressor speed and valve opening.
If operating conditions are near the limit of the envelope or outside of it, the controller will implement corrective actions so as to keep the set point within the limits allowed by the manufacturer. In these cases, therefore, eff ective compressor speed may not correspond to the cooling capacity required by the temperature controller and superheat may diff er from the value set by the user. If operating conditions remain outside of the envelope for a time exceeding the alarm threshold (default 180 s), the compressor will be stopped and an alarm signal will be activated, indicating the zone where operation was outside of the envelope.

These are expressed in rps/s, and represent the maximum speed variation allowed each second to increase or decrease operating speed or stop the compressor. When the request varies more quickly, the compressor speed will change according to the set ramps.

Equalising procedure (screen Daa02, Dab05)
If, when the compressor is requested to start, the diff erence between discharge pressure and suction pressure is greater than the maximum allowed for start-up (cI5), the equalising procedure (cE1) can be activated:
• using the expansion valve; this procedure involves opening the valve by a set percentage (cE3) and for a set time (cE2);
• using an equalising solenoid valve;
• When the pressure diff erential is less than (cI5), the expansion valve is positioned at the initial opening set for CP1, while if equalising by solenoid is set, this is closed and the compressor can be started.

cIS time
• The total procedure lasts cIS x no. of evap., and is divided into equal sections corresponding to the number of evaporators.
• In each section, the valve on that evaporator is active (PEV), while the others are closed.
• When the valves start normal control again at the end of the procedure, these return to the last position saved at the start.
• The compressor speed varies between StartUp (cIA) and cIb (keeping envelope control active), based on the weight of the evaporator.
• If Treg falls below the set point minus a set delta, the procedure ends, without a delay, for the cabinet/showcase in question.
The changeover from one section to the next occurs as follows:
• showcase 1 ends the procedure;
• the valve on showcase 2 opens;
• the valve on showcase 1 closes after a 5 second delay.
High discharge temperature control (screen Daa03, Daa04, Daa05)
Discharge temperature is an important indicator of the compressor’s health: by continuously monitoring this value, a procedure can be implemented to keep the temperature under control.
Envelope control involves actions to adjust compressor speed and expansion valve opening, so as to keep discharge temperature within the allowed limits. In addition, a liquid injection procedure can also be confi gured:
1. by an ON/OFF liquid injection valve activated when the discharge temperature exceeds a threshold, and deactivated when it returns below the threshold minus a diff erential.
2. by an electronic valve (connected to connector J8 - see Fig. 2.d); in this case there will be continuous modulation of operation with P+I control set by parameter LII.

Compression ratio control
When normal operating conditions mean the compressor works at a compression ratio below the limit allowed by the envelope, two procedures can be activated:
• MOP procedure using EEV: the valve closes, increasing the pressure diff erential and consequently the compression ratio
• compressor acceleration: increasing the speed, the compressor increases the pressure diff erential and consequently the compression ratio.
Compressor shutdown for pump down
The pump down procedure is used to improve compressor restarts without the risk of liquid on the suction side. In this case, the following actions are carried out:
• the EEV closes;
• the compressor continues operating and speeds up (or down), after the time cPL from when the function starts, based on the distance from the threshold, and stops when the pressure reaches cPt, or when the maximum time cPM has elapsed;
• during the procedure, the LP alarm is disabled.
6.6.2 ON/OFF compressor control
In the branch used to confi gure the type of compressor, ON/OFF compressors can also be selected; in this case, control is based on temperature too.
The PID remain parameters the same (kp and ti), with the same meaning for both inverter-controlled and on/off compressors.
The compressor is started when the request exceeds 98% and stops when it falls below 2%..
In multi-evaporator confi gurations, the suction valves close when the compressor is OFF.
Pressure control with ON/OFF compressor
If a multi-evaporator system is confi gured, control can be performed based on pressure rather than temperature. In this case, the control sequence is as follows:
• the compressor is started (based on pressure) by one of thermostats on the cabinet/showcase, with active envelope control;
• the individual EEV valves strive to maintain the desired controlled temperature inside the cabinet/showcase, as set on screen Ca02.
6.6.3 ON/OFF control with multi compressors
On screen Dab13, a delay time can be selected for activation (or deactivation) between one compressor and the next.
6.6.4 Propane (R290) inverter compressor control
Propane compressors can be selected for the specifi c part numbers listed below.

As for the HFC models, the compressor is selected during the wizard to be completed when commissioning the unit
(see Commissioning). Before selecting the installed compressor, make sure that the Power+ inverter is connected to the Heos controller.
On screen Dab01, the compressors available for the application can be selected; currently this is:
• SIAM SPB 172
Other models can be implemented on request by contacting Carel HQ directly.
In the same way as for the other types of compressor, the thermodynamic and timing parameters are an integral part of the Heos controller software, so as to control the compressor while verifying that its operating conditions are always within the limits allowed by the manufacturer.
The electrical parameters are written into the Power+ inverter fi rmware, allowing sensorless control to manage the compressor eff ectively.
Furthermore, when selecting the compressor, all the thermodynamic and timing parameters are automatically confi gured.
Therefore, no other parameters need to be set before starting the compressor.
All of the compressor management functions (envelope, on/off ramps, equalisation, oil recovery, discharge temperature...) are the same as for HFC compressors.
Note: for this type of compressor, multi-evaporator management is
NOT available, rather the compressor can only be combined with a single evaporator.
The pressure probes must be suitable for use with propane (e.g.
SPKT***P**) ,
The confi guration for on/off compressor control (up to 5 compressors in
5 circuits) also allows the selection of propane compressors. In this case, there are no analogue inputs for managing the high and low pressure, but rather only the possibility to manage a digital alarm (for example, thermal overload) selected from the digital or/and universal channels (on screens Bac15 to Bac19); alarm discharge temperature management by probes selectable (Baa17 ... 21) with threshold setting on the mask Dad07.
The position of the digital outputs is selected on screens Dad15 to Dad19.

Screens Dcb01-Dcb04 can be used to set up to 8 defrost events managed by the clock (RTC) on the controller, and activate Power Defrost. The screen for setting the fi rst two events is shown below:
For Master/Slave networks with synchronised end defrost, control resumes on all units when the last of these reaches dt1 or the time dP1 has elapsed.
The units in standby remain in the dripping stage: fans off and cooling deactivated (or at minimum capacity without heater defrost).

Heos can manage the following types of defrost, depending on the setting of parameter d0: electric heater, hot gas, reverse cycle. The defrost can end based on temperature, in which case the defrost probe Sd needs to be installed, or after a set time. In the fi rst case, the defrost ends when the defrost probe Sd reading exceeds the end defrost value dt1 or the time dP1 has elapsed, while in the second case, only when the time dP1 has elapsed. If end defrost by temperature is selected, an alarm can be activated if the defrost ends when exceeding the maximum time. At the end of the defrost, a dripping stage can be activated (if the dripping time dd is greater than 0), in which the cooling cycle is not active and the fans are off , and then a further post-dripping stage, if the time Fd
(screen Dd02) is greater than 0, during which the cooling cycle restarts with the fans off . Parameter d6 (screen Ec02) can be used to select what is displayed on the PLD during the defrost.

Maximum time between consecutive defrosts (parameter dI)
Parameter dI (screen Dca03) is a safety parameter used to perform cyclical defrosts every “dI” hours, even without the Real Time Clock (RTC). It is also useful if the pLAN or RS485 serial network is disconnected, when defrosts are controlled by the supervisor. At the start of each defrost, irrespective of the duration, an interval starts being counted. If this interval exceeds dI without a defrost being performed, one is started automatically.
The count is always active even if the controller is OFF. If set on Master controller, the parameter has eff ect on all the sub-LANs connected, if set on a Slave controller, it only has an eff ect locally.

Defrost at start-up (parameter d4)
Defrost at start-up has priority over the control request. On the Master controller the defrost at start-up will be a network defrost, while on the
Slave controllers it will be local.
Defrost delay at start-up (parameter d5)
Also active when d4=0. If the digital input is set to enable or start a defrost via an external contact, parameter d5 represents the delay between enabling or calling the defrost and when it eff ectively starts. In a Master/
Slave network, to activate the heater defrost via a digital input on the
Master, it is suggested to use parameter d5 to delay the various defrosts on the Slaves, thus avoiding current overloads.
Example: if due to an RTC fault, the scheduled defrost (td3) is not performed, after the safety time dI, a new defrost starts.

Pump Down
With a heater defrost, the pump down cycle is always performed, in which the evaporator is emptied of liquid refrigerant immediately before the defrost starts. When starting the defrost, the expansion valve is immediately closed, and the compressor stops with a deceleration ramp lasting a few seconds. In this stage, the refrigerant is pumped to the high pressure section of the unit.
Other defrost management parameters concern the activation delays, synchronisation between Master and Slave, defrost stages such as pump down and dripping, and advanced functions, including
• Running time;
• Sequential stops;
• Skip defrost;
• Power defrost.
End defrost synchronised by Master (parameter d2)
This parameter determines whether or not, in a local network, at the end of the defrost Heos waits for an end defrost signal from the Master before restarting the cooling cycle.

Running time defrost (parameters d10, d11, dA1)
Running time is a special function that determines when the refrigeration unit needs defrosting. In particular, it is assumed that if the evaporator temperature measured by probe Sd remains continuously below a certain set threshold (d11) for a certain time (d10), the evaporator may be frozen and a defrost is activated. The time is reset if the temperature returns above the threshold. The probe used is set by parameter dA1. In addition, at start-up the time dA2 must elapse before the running time procedure is activated.

Sequential stop mode is especially useful for high-normal temperature refrigeration units, and is based on intelligently stopping control to allow the evaporator to defrost naturally by the fl ow of ambient air only, without activating the defrost output.
If the function is enabled (parameter dS0), during normal control two countdown timers are started:
• OFFTIME: counts down when control has stopped and paused during control;
• ONTIME: counts down during control and paused when control has stopped.
Two events may occur, with reference to the following fi gure:
• OFFTIME reaches zero (instant C): OFFTIME and ONTIME are reset with the values of dS1 and dS2 and the defrost is considered as having already been completed. Control resumes;
• ONTIME reaches zero (instant A): OFFTIME is reset with the value of dS1 and the natural defrost cycle starts, which lasts for the time dS1. At the end of the defrost (instant B), OFFTIME and ONTIME are reset with the values of dS1 and dS2 and control resumes.

Skip defrost (parameters d7, dn, do)
The function applies to defrosts that end by temperature, otherwise it has no eff ect. The Skip defrost function evaluates whether the defrost duration is less than a certain threshold (dn) and based on this establishes whether or not the subsequent defrosts will be skipped.

The algorithm keeps a counter of the defrosts to be skipped:
• if the defrost ends in a time less than dn1, the counter of the defrosts to be skipped is increased by 1;
• if the defrost ends normally, the next defrost is performed;
• when the counter reaches 3, three defrosts are skipped;
• at start-up, the defrost is performed “do” two times without increasing the counter.
Power defrost (parameters ddt, ddP)
Power defrost is used to increase the end defrost threshold dt1 and/or the maximum defrost duration dP1. These increases allow longer and more eff ective defrosts. Power defrosts are performed on each defrost call during night-time status or when suitably confi gured by the RTC parameters (sub-parameter P of parameters td1 to td8), so as to allow the user to choose the conditions that are most suitable for this special procedure. Power Defrost is activated when at least one of the increases, ddt or ddP, has any value other than zero.

The fans can be turned off in the following situations:
• when the compressor is off (parameter F2);
• during defrost (parameter F3).
During the dripping period (parameter dd > 0) and the post-dripping period (parameter Fd > 0) the evaporator fans are always off . This is useful to allow the evaporator to return to temperature after defrosting, thus avoiding blowing warm hot and moist air into the refrigerated environment.
Variable speed fans
The installation of variable speed fans may be useful in optimising energy consumption. In this case, the fans are powered by the mains, while the control signal may come from a PWM or 0-10 V output. The maximum and minimum fan speed can be set using parameters F6 and F7. Frd in this case represents the variation in temperature for switching fan speed from minimum to maximum. If using the fan speed controller, F5 represents the temperature below which the fans are activated. There is a fi xed hysteresis of 1°C for deactivation.

6.9 Electronic valve
Heos can manage Carel E2V single-pole valves (with 6-wire cable).
Double-pole valves (with 4-wire cable) are incompatible with Heos.
To manage the electronic expansion valve, two additional probes must be installed and suitably confi gured:
• temperature probe for measuring the superheated gas temperature at the evaporator outlet;
• pressure probe for measuring the saturated evaporation pressure/ temperature at the evaporator outlet
Installation notes:
Heos is designed to manage one electronic expansion valve that controls the fl ow of refrigerant inside an individual evaporator. Two evaporators in parallel cannot be managed with just one electronic expansion valve.
The NTC/PTC/PT1000 temperature probe must be installed near the evaporator outlet, according to the standard installation methods (see the installation notes on the E2V instruction sheet). Suitable thermal insulation is recommended. CAREL off ers special types of probes designed to simplify installation in contact with the refrigerant pipe:
• NTC030HF01 for Retail use IP67, 3m, -50T90 °C, 10 pcs
• NTC060HF01 for Retail use IP67, 6m, -50T90 °C, 10 pcs
To measure the saturated evaporation temperature, diff erent types of probes can be used; in particular, the following can be installed:
0 to 5 V ratiometric pressure probe (recommended by CAREL);
4 to 20 mA active pressure probes .
Conversion of the pressure to a temperature value is performed automatically once the refrigerant has been selected (see the paragraph on the compressor)
Heos manages the proportional opening of the electronic expansion valve, adjusting the fl ow of refrigerant in the evaporator, so as to maintain the superheat around the value set for advanced parameter P3 (superheat set point). The opening of the valve is controlled simultaneously yet independently from normal temperature control. When there is a refrigeration call (the compressor is operating), control of the electronic valve is also activated and then managed independently of compressor speed. If the superheat value read by the probes is greater than the set point, the valve is opened proportionally to the diff erence between the values. The speed of variation and the percentage of opening depend on the PID parameters set. The opening is continuously modulated based on the superheat value, with PID control.
Superheat set point (parameter P3)
This is used to set the reference superheat value for the control of the electronic valve. It does not determine the actual superheat value, but rather the desired value. Heos, with PID control, tends to maintain the actual superheat, calculated based on the probe readings, around the value set for this parameter. This is done by gradually varying the opening of the valve based on the diff erence between the actual superheat and the set point.

Important: the set point value calculated depends on the quality of the installation, the position of the probes and other factors.
Consequently, depending on the installation, the set point read may deviate from the actual value. Set point values that are too low (2...4 K), albeit ideally usable, may cause problems involving the return of liquid refrigerant to the compressor.
Valve position at start control (parameter cP1)
This is used to set the position of the valve as a percentage when control starts. High values ensure intense and immediate cooling of the evaporator when each call is sent, however may cause problems if the valve is oversized with reference to the cooling capacity of the controller.
Low values, on the other hand, allow a more gradual and slower action.
The values set should be coherent with compressor start-up speed.

PID control of the expansion valve (parameters P4, P5, P6)
The opening of the electronic valve is controlled based on the diff erence between the superheat set point and the actual superheat calculated by the probes. The speed of variation, the reactivity and the ability to reach the set point depend on three parameters:
• Kp = proportional gain, parameter P4;
• Ti = integral time, parameter P5;
• Td = derivative time, parameter P6;
The ideal values to be set vary depending on the applications and the utilities managed, nonetheless default values are proposed that allow good control in the majority of cases. For further details, refer to classic
PID control theory.

P4: this represents the amplifi cation factor. It determines an action that is directly proportional to the diff erence between the set point and the actual superheat value. It acts on the speed of the valve, in terms of steps/°K. The valve moves P4 steps for every degree variation in the superheat, opening or closing whenever the superheat increases or decreases respectively. It also acts on the other control factors, and is valid in both normal control and with all emergency control functionsa.
• High values ==> fast and reactive valve
• Low values ==> slow and less reactive valve.
P5: this represents the time required by the controller to balance the diff erence between the set point and the actual superheat. It practically limits the number of steps that the valve completes each second. It is only valid during normal control, the special functions in fact have their own integral time.
• High values ==> slow and less reactive valve
• Low values ==> fast and reactive valve
• P5 = 0 ==> integral action disabled
P6: this represents the reaction of the valve to variations in the superheat.
It amplifi es or reduces variations in the superheat value.
• High values ==> rapid variations
• Low values ==> limited variations
• P6 = 0 ==> diff erential action disabled
6.10 Protection functions
LowSH Low superheat
To prevent too low superheat values that may cause the return of liquid to the compressor or system instability (swings), a low superheat threshold can be defi ned, below which a special protection function is activated. When the superheat falls below the threshold, the system immediately enters low superheat status and activates a control action, in addition to normal control, with the aim of closing the electronic valve more quickly. In practice, the intensity of system “reaction” is increased.
If the device remains in low superheat status for a certain period, a low superheat alarm is activated, with the display showing the message ‘LSh’.
The low superheat signal features automatic reset, when the condition is no longer present or the controller is switched off (standby).

MOP Maximum evaporation pressure
When starting or restarting a system, the compressors may not be able to satisfy cooling demand. This may cause an excessive increase in the evaporation pressure and consequently the corresponding saturated temperature. When the evaporation pressure, expressed in degrees
(saturated), rises above the threshold, after a certain settable time the system enters MOP protection status: PID superheat control is stopped and the controller starts gradually closing the valve with an integration action to return the evaporation pressure below the threshold. The protection function has been designed to allow a gradual return to normal operating conditions, that is, when the critical conditions have ended, the controller temporarily operates with a higher superheat set point until the function is automatically reset.

LOP Minimum evaporation pressure
This function is used to prevent the evaporation pressure from remaining excessively low for too long. When the evaporation pressure, expressed in degrees (saturated), falls below the threshold, the LOP protection is activated, which adds an integration action to normal PID control, specifi cally devised to be more reactive as regards the opening of the valve. PID control remains active, as the superheat must continue to be monitored as to avoid fl ooding the compressor. The LOP alarm is delayed from the activation of the protection function, both are reset automatically when the pressure value, in degrees (saturated), exceeds the threshold.

6.11 Anti-sweat heater or fan modulation
IAnti-sweat heaters are controlled by comparing dew point calculated based on the room temperature and humidity, and the temperature of the showcase glass, measured by a probe or estimated using the showcase outlet, intake and room temperature. Two types of anti-sweat heater control are available:
• PI (proportional, integral);
• fi xed activation (manual control).
The conditions for activation of the algorithms are as follows:
PI fi xed activation (manual control) rHd > 0 rHd = 0; rHt >0
If the glass probe temperature is estimated (not read), PI control becomes proportional only. Based on a series of conditions, the PI algorithm ceases and, if activated, control with fi xed activation commences. In this case, alarm ACE is signalled on the display.
Condition
Glass temperature probe not valid
Cause physical probe not confi gured or error; the estimate of the glass temperature probe cannot be used because the outlet probe or intake probe is not confi gured or has an error or the room probe is broken or missing
Dew point not valid room humidity and/or temperature probe are not confi gured and operating; the serial dew point value is not available .

Inputs
The room humidity (SU) and temperature (SA) probes can be (see parameters /FL, /FI):
• connected to the Master, which automatically shares them with the Slaves;
• connected locally to each controller;
• sent from the supervisor via the serial probes.
Alternatively, the supervisor can directly supply the dew point value
(Sdp) using the serial probes. The glass temperature probe (Svt) can be connected directly to each controller (see parameter /FM), or estimated.
The estimate of the glass temperature probe reading is performed internally when: room temperature (SA), outlet temperature (Sm) and intake temperature (Sr) are available, and depends on parameters Ga, Gb and Gc. Parameters rHo, rHd determine the modulating output.

If one of the probes is not available (SA or either Sm or Sr), only fi xed activation control will be possible, based on parameters rHu and rHt.
Outputs
The analogue output for the anti-sweat function can be 0-10 VDC
(analogue output Y1, Y2, Y3) or PWM (SSR output OUT2).
If using the 0 to 10 Vdc output, the output voltage will vary based on the anti-sweat control activation percentage (see Fig. 6.ad). This output can be used to directly control an FCS controller, for example.
If using SSR output Out2, the output will be active for a time that is proportional to the function activation percentage (see Fig. 6.ad), with a period equal to rHt (manual anti-sweat activation time, settable between
1 min and 30 min).
The anti-sweat control activation percentage (OUT) depends on the diff erence between the dew point calculated and the glass temperature probe value (measured or estimated), on the value of parameter rHo
(off set), the value of parameter rHd (diff erential), the Cutoff (rhB) and the hysteresis (rHC) (see the following fi gure).

Min: minimum output fi xed at 10%; Max: maximum output fi xed at 100%.
The action is only proportional if the estimate of the glass temperature is used, and proportional and integral (Tint=240 s, constant) if the actual glass temperature probe is used. The aim of the integral action is to bring the glass temperature towards the set point (Sdp+rHo).
Important: if using supervisor serial probes to propagate the room temperature, humidity or dew point values, the Heartbeat on the
“Dew point propagation plugin” needs to be set appropriately. This is used by the HEOS controller to understand whether the supervisor is continuing to send new values. If Heos does not receive any new values for more than 30 minutes, alarm ACE is signalled and manual control
(fi xed activation) is activated. This is useful in the event of power failures on the supervisor.
The probe not updated alarms are normally displayed when the unit is fi rst started, i.e. when the variables have yet to be initialised.
Fixed activation control (manual control)
Control depends only on parameters rHu and rHt and follows the trend shown in the fi gures.

Heos can also optimise the condenser control (generally water-cooled) the condensing pressure/temperature, however can also use the water temperature; there are two main types of valves, two-way or threeway mixing valves. In certain special cases (for example, when ambient heat can be recovered from), air-cooled condensers can also be used; in this case, control is performed based on the condensing pressure/ temperature. Consequently, two types of condenser can be chosen on screen Daa06 (displayed only if both analogue outputs have been activated): water-cooled and air-cooled

• Parallel connection to the condenser
• Serial connection to the condenser

6.14 “Dual temperature” management
This procedure provides “2 sets” (setA and setB) of parameters for managing both a low temperature (setB) and medium temperature cabinet (setA).
The set of parameters (setA or setB) can be selected either via the digital input set on screen Bac20 or on the keypad via screen Df04; the function is enabled and the type of selection (keypad/supervisor or digital input) is set on screen Df03.
In the event of changes to the cabinet circuit, a digital output set on screen Bad20 can be used; the active set used (A or B) for the digital output is always selected on screen Df03.
The parameters (setA and setB) are programmed on screens Df05-13 for setA and screens Df14-22 for setB; if the active set is “A”, then only the parameters in setB will be visible; vice versa if the active set is “B” only the parameters in setA will be visible. This is because if set “A” is active, the corresponding operating settings are currently selected in the respective control loops, while setB can be set on screens Df14-22; switching the sets swaps the parameter settings.

8. SIGNALS AND ALARMS
Heos can manage both alarms relating to the status of the digital inputs and to system operation. For each alarm, the following are controlled:
• actions on the devices, if required
• output relays
• red LED on the terminal and buzzer
• any activation delay
The complete list of alarms, with the related information as described above, is available in the “Alarm table”.
Note : A maximum of 50 alarms can be logged; after this limit any new events overwrite the oldest ones, which are therefore deleted.

All alarms feature the following behaviour:
• When an alarm is activated, the red LED fl ashes and the buzzer and alarm relay are activated (when confi gured)
• Pressing the button, the red LED stays on steady, the buzzer is muted and the alarm screen is shown
• If there is more than one active alarm, these can be scrolled using and
• Pressing the button again for at least 3 seconds manually resets the alarms, which are cleared from the display unless others are active
(they are saved in the log)
The compressor high and low pressure alarms can be set in branch
Dad01-04. In addition to the high and low pressure alarm thresholds, with corresponding delays for the low pressure alarms, this screen can also be used to set the type of reset when exiting the envelope. For the delay and type of reset, also see the alarm table (par. 8.5).
8.3 EEV valve protector alarms
The alarms corresponding to the LowSH, LOP, MOP and High Tcond protectors are only activated during control when the corresponding activation threshold is exceeded, and only when the timeout defi ned by the corresponding parameter has elapsed. If a protector is not enabled
(integration time= 0 s), no alarm will be signalled. If before the expiry of the timeout, the protector control variable returns back inside the corresponding threshold, no alarm will be signalled.
Note: this is a likely event, as during the timeout, the protection function will have an eff ect.
If the timeout relating to the control alarms is set to 0 s, the alarm is disabled. The protectors are still active, however. The alarms are reset automatically.
Reset
Alarms can be reset manually or automatically:
• Manual: the alarm is reset by pressing the button twice, the fi rst time displays the corresponding alarm screen and mutes the buzzer, the second (extended, for at least 3 seconds) cancels the alarm (which is saved in the log). If the alarm is still active, the reset has no eff ect and the signal is shown again.
• Automatic: when the alarm condition ceases, the alarm is automatically reset, the LED comes on steady and the corresponding screen remains displayed until the button is pressed and held; the alarm is saved in the log.
For manual reset, the functions associated with the alarm will not be reactivated until the alarm is reset, while for automatic reset, the functions are reactivated as soon as the alarm condition ceases.
Log
The alarm log can be accessed:
• from branch F.d of the main menu
• pressing and then when there are no active alarms
The alarm log screens show:
1. the chronological number of the event (no. 01 is the oldest alarm)
2. time and date of the alarm
3. the alarm code (see the table in par. 8.5)
4. short description of the logged alarm
5. control probe reading and set point, superheat reading and set point, discharge temperature value, envelope zone, evaporation and condensing pressure values converted to temperature.
The last screen displayed is used to reset the log.

Alarm parameters and activation
AL (AH) is used to determine the activation threshold for the low (high) temperature alarm LO (HI). The value set for AL (AH) is continuously compared against the value measured by the probe defi ned by parameter
AA. Parameter Ad represents the alarm activation delay, in minutes; the low temperature alarm (LO) is activated only if the temperature remains below the value of AL for a time greater than Ad. The thresholds may be relative or absolute, depending on the value of parameter A1. In the former case (A1=0), the value of AL indicates the deviation from the set point and thus the activation point for the low temperature alarm is: set point - AL. If the set point changes, the activation point also changes automatically. In the latter case (A1=1), the value of AL indicates the low temperature alarm threshold. The low temperature alarm is signalled by the buzzer and error code LO on the display. The same applies to the high temperature alarm (HI), with AH instead of AL. I
The meaning of parameters AL2, AH2, Aa2 and A2 is similar to AL, AH, Aa,
A1, relative to the second set point.

9.1 Setting the controller’s address
The controller’s pLAN address set by default in the factory is 1. The controller’s address can be set via a terminal connected in the pLAN network. The controller is assigned a private (Pr) or shared (Sh) terminal with address 32. The address of the external terminal can be set in the range between 0 and 32; addresses between 1 and 32 are used by the pLAN protocol, while address 0 identifi es the Local terminal protocol, used for point-to-point connections and to confi gure the controller (this procedure is only possible with a pGD terminal and one pCO only).
If the controller with the default setting (address=1) is connected to an external terminal (address=32), communication is established and the display on the external terminal replicates the display on the built-in terminal, if featured. If, on the other hand, the controller has a diff erent address (e.g. 7) and the terminal is not set to communicate with the controller with this address, once the connection has been established, the terminal displays a blank screen.
In this case, proceed as follows.
Procedure:
1. Press the UP, DOWN and Enter buttons together to access the screen for setting the terminal’s address.
Display address setting............:02
I/O Board address..:07
4. Power on the controller while holding the Alarm and Up buttons together, until the following screen is shown.
selftest please wait...
5. Use UP and DOWN to set the controller’s pLAN address to 7 and confi rm by pressing Enter.
pLAN address: 7
UP: increase
DOWN: decrease
ENTER: save & exit
2. Set the address of the display, 0 for point-to-point connections.
Confi rm by pressing Enter.
Display address setting............:00
9.2 Setting the terminal’s address and connecting the controller to the terminal
After setting the controller’s network address (see previous paragraph), to establish connections between the controller and the terminal, the terminal’s address needs to be set.
Procedure:
1. Press the UP, DOWN and Enter buttons together. The screen is displayed for setting the terminal’s address. Set the address to 2 and confi rm by pressing Enter.
Display address setting............:02
3. Power off the controller.

4. Set terminal 1 (Trm1) with address 2 as private (Priv) or shared
(Shared) according to the application, and confi rm to exit. After a few seconds, the connection will be established.
5. To add a second terminal, repeat steps 1 to 4.
9.3 Uploading/updating the software
The following methods can be used to update the fi rmware and acquire the log fi les on pCO controllers:
• SmartKey programming key;
• pCO manager tool, installable on a PC.
Smart key
The PCOS00AKY0 key is an electronic device used to program and service the pCO sistema family controllers. PCOS00AKY0 simplifi es data transfer between the controllers installed and a personal computer by exploiting the high capacity fl ash memory for storing software applications, BIOS and variable logs. The pCO is connected directly via the telephone connector using the cable supplied, while to transfer the data to a personal computer, the USB adapter code PCOS00AKC0 is required. The power supply comes either via the USB port on the PC or from the controller, therefore no external power supply is needed.

Tab. 9.d
The key is factory-programmed in read/write mode (type C) so that it can be used immediately to transfer software from one controller to another.
When the key is connected to the personal computer, the symbols have the following meanings:
Flashing Waiting for connection to PC
Alternating When connected to PC indicates data transfer in progress
The programming key is compatible starting from BIOS version 3.43 and
BOOT version 3.01. For more detailed information on programming the key, see the pCO Manager program manual.
Using the Smart Key with the pCO/μPC
Switch off the pCO, remove any peripherals connected in the pLAN and plug the key into the telephone connector on the controller. When switching on again, all the symbols light up momentarily and the buzzer emits a beep. A few seconds later the key becomes operational. During this period the symbols will fl ash. The controller then enters programming mode and the start button lights up steadily. Press the button to start data transfer.
Important:
• If the key is type B, C or G (in write mode) pressing the start button will immediately delete the software already loaded on the pCO.
• Do not remove the key while data is being transferred to the key itself, as the fi le being transferred will be lost and the corresponding space will not be restored. To restore the original capacity all the fi les will need to be deleted. If the key is type “C” or “G”, simply perform a new application read operation.
Meanings of Buttons/Symbols start start+ start+ start+ mode
Flashing: the key is connecting to the pCO. During this phase, which may last a few seconds, the start button is disabled.
Flashing: The key has detected the pCO and is checking the access rights.
On steady: Pressing the start button will start writing the software to the pCO.
On steady: Pressing the start button will start reading the software from the pCO.
On steady: Pressing the start button will start reading the logs from the pCO.
On steady: In case of C or G keys, pressing the button for 1 second switches from read to write.
Tab. 9.b
If the key is type C of G, pressing the “mode” button for 1 second switches from read to read logs (G only) or to write. The symbols (write to pCO),
(read from pCO), (read logs) refl ect the selected status. If the key is not type “C” or “G”, the “mode” button is disabled and off . The “start” button starts the read or write operation, indicated by the fl ashing of the corresponding symbol ( or ) at a frequency proportional to the progress of the operation.
When the operation is completed, the buzzer will sound intermittently for 2 seconds. Pressing the start button again will make the buzzer sound without repeating the operation. To repeat the operation, the key must fi rst be unplugged. In case of error the symbol will light up together with the other LEDs. The following table can help you fi nd the cause of the problem.

Commissioning: basic concepts
Note: The following paragraphs are from the online help of pCO
Manager, to which the user is referred for further details.
Commissioning is a confi guring and real-time monitoring software that can be used to supervise the performance of an application program installed on a pCO, to start up the pCO and to perform debugging and maintenance. With this software the user can set the confi guration parameters, edit the values of volatile and permanent variables, save on fi le the trends of the unit’s main quantities, manually manage the unit’s I/O using simulation fi les and monitor/reset the alarms of the unit on which the device is installed.
Work carried out with Commissioning is preceded by confi guring the work environment, which is typically done by the project designer. The active project in 1Tool is automatically loaded by pCO Manager.
The project designer can use the confi guration functions of Commissioning to decide which variables should be subjected to monitoring, logging, trend-monitoring and event-monitoring, to organize variables into categories and to create sets of confi guration parameters.
55
Operators using Commissioning for maintenance will be able to see the necessary variables and to draw from preset confi guration values.
Support fi les
Once the design of the application is completed, 1Tool generates a number of fi les in the compiling stage, two of which are required by Commissioning:
• <nomeApplicativo>.2CF [<ApplicationName>.2CF] (variable descriptor)
• <nomeApplicativo>.2CD [<ApplicationName>.2CD] (category and access profi le descriptor)
In addition to these fi les, the software also manages the <nome applicativo>.
DEV [<Application Name>.DEV] fi le, which contains the unit’s preset parameters. When the user has fi nished using Commissioning, whether for confi guration or monitoring purposes, the following fi les can be generated:
• <nomeApplicativo>.2CW [<ApplicationName>.2CW] (descriptor for categories, access profi les, monitoring groups);
• <nomefi leCommissioningLog>.CSV [<FilenameCommissioningLog>.
CSV] (fi le used for the commissioning log, containing data of the variables logged during monitoring).
Therefore, to confi gure Commissioning the following fi les are required:
.2CF, 2CD and, if necessary, the .DEV fi le, which can be imported or exported. For monitoring purposes, in addition to the fi les above, it might also be necessary to have the .2CW fi le, containing the defi nition of the work environment. The commissioning log fi le is a simple output fi le.
pCO Load: basic concepts
pCOLoad is the module that manages:
• uploading to the fl ash memory (of the device or of the ProgKeyX key installed on the pCO);
• uploading to the NAND memory of certain devices;
• downloading the log fi le, .DEV fi le and P memory (from the fl ash memory);
• downloading fi les from the NAND memory, if present.
The fi les exchanged with the Flash memories of pCO controllers are:
• BOOT.BIN (download reserved, upload enabled from menu)
• BIOS.BIN (download reserved)
• <nomeApplicativo>.BLB [<ApplicationName>.BLB] (download reserved)
• <nomeApplicativo>.BIN [<ApplicationName>.BIN] (download reserved)
• <nomeApplicativo>.DEV [<ApplicationName>.DEV]
• <nomeApplicativo>.GRT [<ApplicationName>.GRT] (upload only, from which the .GRP fi le is extracted)
• <nomeApplicativo>.IUP [<ApplicationName>.IUP]
• <nomeApplicativo>.LCT [<ApplicationName>.LCT]
• <nomeApplicativo>.PVT [<ApplicationName>.PVT]
• <nomepCOlog>.BIN, <nomepCOlog>.CSV, <nomepCOlog_GRAPH>.CSV
[<pCOlogName>.BIN, <pCOlogName>.CSV, <pCOlog_GRAPHName>.
CSV] (only if log fi les have been confi gured, download only).
The fi les exchanged with the NAND memories of pCO controllers are:
• any fi le that the pCO can independently copy to fl ash memory (see list);
• external fi les (e.g. .pdf or .doc fi les for documentation).
LogEditor: basic concepts
LogEditor is the module used to confi gure the log fi les of pCO devices
(pCO logs). Confi guring pCO logs consists in defi ning a number of sets of variables in which to specify which variables should be logged, the logging method (by frequency or by event) and the minimum number of loggings required. Confi guration is based on a binary fi le (.PVT – Public
Variable Table), which is generated by 1Tool and contains the descriptive data of the variables that can be logged.
All the log confi gurations so defi ned are saved in the .LCT (Log
Confi guration Table) binary fi le, which must be uploaded to the pCO together with the .PVT fi le. Log confi guration data is also saved in a fi le that can be used only by LogEditor – the .LEF fi le, which must be saved to be edited with LogEditor as necessary.
LogEditor can be used even when the device is not connected. Once the fi les for logging are uploaded to the pCO, the pCO saves the logged data in the following fi les:
• .BIN fi le containing all the data in binary format;
• .CSV fi le containing the same data in a generic format with values separated by commas;
• *_GRAPH.CSV containing the same data to be used for charting purposes.
