GENERALITY
For operator safety and practicality, the VISION SC600 system envisions three
programming levels; the first for configuration of the frequently amendable SETPOINT
parameters only, the second for programming and setting of the main parameters relating
to the various board functioning modes and the third for programming input/output of the
board. It is not possible to directly access the second or third level from first level
programming, exit current programming first.

SYMBOLS
5.6
For practicality we will use the following symbols:
• ()the UP key
that performs value increase functions;
• the DOWN key
that performs value decrease functions.
SETPOINT SETTING AND DISPLAYING
5.7
1. Press the SET COMPRESSOR key to display the current SETPOINT in Bar.
2. Keeping the SET COMPRESSORI key pressed and pressing one of the () o ()
keys, the SETPOINT value can be amended. Release the SET key to return to displaying
the regulation probe value; memorising of the made amendments will automatically
happen.
NOTE:
Similarly for the setting of the setpoint related to fans repeat the above steps using the
SET FANS key instead of the SET COMPRESSORS key.
While viewing the SET POINT value in Bar (SET button pressed), if you press the standby
key at the same time, you will view the value changed to °C depending on the type of Gas
set. While viewing the value in °C, it will not be possible to change the set through the
arrows.
FIRST LEVEL PROGRAMMING (User level)
5.8
To access the first level configuration:
1. Keep the keys () and () pressed simultaneously for a few seconds until the first
programming variable appears on the display.
2. Release the keys () and ().
3. Using the () key or () key, select the variable to be amended.
4. After having selected the wanted variable, it will be possible to amend its setting by
keeping the SET COMPR (or SET FANS) key pressed and by pressing one of the () or
() keys.
To exit the menu once the configuration values are set, simultaneously keep the () and
() keys pressed for a few seconds, until the pressure measure value appears again.

ACTIVATION SEQUENCE AND DELAYS
5.14
The activation logic of the digital outputs is selected by parameter Seq (for both
compressors and fans).
NB c / u indicates compressors / fans parameter, i.e. t1c / U indicates both parameters T1c and t1U.
With SEq=1, the activation of digital outputs always follows the 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
sequence and the 10, 9, 8, 7, 6, 5, 4 , 3, 2, 1 disabling one complying with the t1C/U,
t2C/U, t3C/U, t4C/U times. If an output is not available because it is alarm, it will
be temporarily excluded from the sequence.
Rev. 02-17
USE AND MAINTENANCE MANUAL
Pag. 23
VISION SC600
CHAP. 5 - Data Programming
With SEq=0 the activation/deactivation of the digital outputs is operation time-based, and
in particular:
- The output that has the least number of operating hours in times t1C/U, t2C/U, t3C/U
and t4C/U, and that is available at that time (therefore not in alarm).
- The output that has the largest number of operating hours in times t1C/U, t2C/U, t3C/U,
t4C/U is deactivated.
Delays on the activations of the outputs
“t1C/U” determines the minimum time that must elapse between the insertion of a step and
the next one. This parameter avoids breakaways caused by simultaneous start-ups.
“t2C/U” determines the minimum time that must elapse between the deactivation of two
different steps.
“t3C/U” determines the minimum time that must elapse between two subsequent
insertions of the same step. This parameter allows you to limit the number of startups per hour if the controlled motors require this.
“t4C/U” determines the minimum time that must elapse between one shutdown and
the next insertion of the same compressor step.
On the LCD display the icons bar relative to fans and compressors (see par 5.4 ) will flash
when its output is pending ON or OFF due to these times.

INPUTS AND OUTPUTS CONFIGURATION
5.15
The configuration of the outputs of the 100 N Master unit can be set via the nC, nU and
NPC parameters. Each output can be associated with the relative protection via the I1, I2,
… , I15 digital inputs.
The nC, nU and NPC parameters are closely associated with each other . The maximum
number of compressors depends on the number of fans set and if there is any capacity
control. The sum of the fans + compressors must not be greater than 10 if there is no
capacity control (NPC=0). If the capacity control is activated (NPC=1 or -1), each
compressor is associated with an additional output to check the relative splitting valve.
Therefore, the sum of twice the compressors plus the fans must be less than or equal to
10 (maximum number of outputs). Recap:
Active capacity control
(NPC=1 or -1)
Disabled capacity control
(NPC=0)
Maximum number of
Maximum number of
compressors
Fans
5 – [(number of fans nU)/2]
10 – (number of compressors nC*2)
10 – (number of fans nU)
10 – (number of compressors nC)
Compressors and fans have a sliding-based management: the first outputs are considered
as “Compressor outputs”, followed by the “Capacity control outputs” and finally the “Fan
outputs”. If, for instance, you set NPC=1, nC=3, nU=3 then:
- digital outputs 0, 1, 2 are “Compressor outputs”;
- outputs 3, 4, 5 are associated with the capacity control of the compressors;
- outputs 6, 7, 8 are the digital outputs that control the fans.
If a compressor is eliminated, i.e. changed from nC=3 to nC=2, then:
- outputs 0, 1 = compressor outputs;
- outputs 2, 3 = capacity outputs;
- outputs 4, 5, 6 = fan outputs.

OPERATING MODE –INVERTER MANAGEMENT
The operating mode is selected via the iEn parameter.
iEn = 0: inverter management deactivated
If iEn=0 both the fans and the compressors are managed with digital outputs and sideband control.
-
For the compressors:
Based on the value of the “SET COMPRESSORS”, "r0C" and "nC" parameters, the
controller calculates the various areas where there is a request to enable and disable the
compressor outputs (steps) by positioning the various switch-ons and switch-offs in the
r0C differential range. Each step has a r0C/nC differential (where nC is the number of
compressors). The combination of the outputs to the steps depends on the setting of the
Seq. variable. If, for instance, we consider Seq=1, for Compressor output no.2 the
enabling will occur at SET_COMPR+(r0C/nC)*2 (constant 2 refers to step 2) and the
disablings will occur at SET_COMPR +(r0C/nC)*1 (see graph no.1 or graph no.2 ).
The number of enabled compressors depends on the deviation between the value
measured by the adjustment pressure sensor (located at the intake) and the set intake
Setpoint.
-
For the fans:
Based on the value of the “SET FANS”, ''r0U'' and ''nU'' parameters, the controller
calculates the various areas where there is a request to enable and disable the fan outputs
(steps) by positioning the various switch-ons and switch-offs in the r0U differential range.
Each step has a r0U/nU differential (where nU is the number of fans). The combination of
the outputs to the steps depends on the setting of the Seq. variable.
If, for instance, we consider Seq=1, for Fan output no.2 the enabling will occur at
SET_VENT+(r0U/nU)*2 (constant 2 refers to step 2) and the disablings will occur at
SET_VENT +(r0U/nU)*1 (see graph n0.3).
The number of fans enabled depends on the deviation between the value measured by the
adjustment pressure sensor (on the supply line) and the set supply Setpoint.

iEn = 1: compressor inverter management activated
If iEn=1, compressor 1 is managed with the 0-10V output and a side-band control. The
compressor 1 digital output is used to enable the inverter, the other digital outputs control
the remaining compressors with a side-band control.
The adjustment of the inverter is based on the operation shown in Graph no.4 as the
intake pressure varies:
-
when the first compressor step is activated, the inverter output is set to the minimum iMc
value.
- Afterwards,
the inverter output varies in proportion with the value read by the intake sensor
(within a 0-10V range) and the other compressor outputs are controlled on a side-band basis;
- when
there is a request to enable the second compressor stage and after the t1C time, the
inverter output is gradually reduced down to the iMc value. Compressor output 2 is then
activated and the inverter varies in proportion with the value read by the intake sensor;
-
when a compressor step is disabled, the inverter output is gradually increased until it reaches
the maximum value in the itS time. It then varies in proportion with the value read by the
intake sensor.
CONTROL IN THE EVENT OF ALARMS
With the compressor output no.1 alarm input activated, the analogue input will be
immediately brought to 0V and the digital output no.1 will be opened after (inverterenabling is removed).

iEn = 2: fan inverter management enable
With iEn=2 you will have the Condenser fan control with 0-10V analogue output and
of
sideband-type adjustment. Digital Output “Fan 1” represents "the condenser fans
inverter activation"; the other fans digital outputs are disabled (all fans are controlled by the
inverter). The compressors are controlled by digital outputs and
sideband-type
adjustment.
The adjustment follows the operation of graph no.5 with the increase of the output
pressure and the decrease of graph no.6.
Output pressure INCREASE (Graph n.5) :
The analogue output of the adjuster will be 0V for output pressure probe less or
equal to point (B) representing the "SET point + iOv offset" value.
If the output pressure probe value is higher than point (B), you will have the analogue
output at 10V for the maximum BOv time. BOv is the Fans Boost times for which the
adjuster output is increased by 100% in order to help the start-up of the fans.
Between points (B) and (C), the analogue output will have a value proportional to the
value of the output pressure probe starting from the minimum value of the parameter (iMv)
up to the maximum value of 10V. With output pressure probe values equal or higher than
point (C), you will have a 10V analogue output. Digital output no.1 represents "the
condenser fans inverter activation" and is ON for pressure values higher than or equal to
the set point and OFF for lower values.

OPERATING MODE – COMPRESSORS CAPACITY MANAGEMENT
With the NPC parameter = ±1, the operation of the compressors is selected and the digital
outputs are controlled on a side-band basis and the CAPACITY CONTROL IS SET TO 50%.
Then there are two possible variants based on the status of the SEq variable designed for the
logical selection to activate the compressors.
-
SEq parameter = 1 (without rotation)
Based on the value of the “SET COMPRESSORS”, "r0C" and "nC" parameters, the
controller calculates the various areas where there is a request to enable and disable the
compressor outputs (steps) by positioning the various switch-ons and switch-offs in the r0C
differential range. Each step has a diC/nC/2 differential (where nC is the number of
compressors).
Therefore, the number of steps is twice the number of the compressors (given the presence
of the capacity control).
For instance, for compressor no.1 the enabling will occur at:
(constant 1 indicates step 1)
and the disabling will occur at:
.
The enabling of the capacity control of compressor no.1 will occur at:
and the disabling will occur at:
(without considering the intervention of times t1C and t2C).

In general, if SEq=1 the activation of the compressors and the capacity control (if one
does not consider the presence of the fans) follows this sequence: C1, PC1, C2, PC2,
C3, PC3, C4, PC4, C5, PC5, C6, PC6, C7, PC7, C8, PC8, C9, PC9, C10, PC10. The
deactivation is based on this sequence: PC10, C10, PC9, C9, PC8, C8, PC7, C7, PC6,
C6, PC5, C5, PC4, C4, PC3, C3, PC2, C2 ,PC1, C1.
The number of compressors enabled depends on the deviation between the value
measured by the adjustment pressure sensor (positioned at the intake) and the set
intake Setpoint, as well as the t1C e t2C times. Namely, the “t1C” time determines the
minimum stay time of a step that has just been enabled, and the “t2C” time the
minimum stay time of a step that has just been disabled.
These two times prevent
considerable temporary pressure changes from causing the compressors to switch on
and off.
Note: on the LCD display, the capacity control is indicated by the fact that the
corresponding pair of LEDs turns on. If a compressor or capacity control is waiting for
the t1C or t2C time, the corresponding LEDs on the display start to flash.
- parameter
SEq = 0 (with rotation)
If SEq=0 the compressors are activated based on their operating time. When there is a
request to activate a step, a compressor with a shorter operating time is activated,
provided it is not in stand-by and that there is no alarm associated with it. Upon a
subsequent request to enable a step, the capacity control of the last compressor
enabled will be activated. The compressor and relative capacity control are always
activated and deactivated in pairs: if the step is disabled, first the capacity control will be
disabled and then the relative compressor.
Note: if the Compressor inverters management is active (parameter iEn=1 or iEn=3), the
capacity control cannot be used.

answers with the high pressure probe measurement (delivery) to the address (Ad+1). If the
VISION SC600 is questioned as a "tool TWMP", it is therefore not possible to set other
instruments at Ad +1.

CHAPTER 7: DIAGNOSTICS
DIAGNOSTICS
7.1
In case of anomalies, the VISION SC600 controller warns the operator using alarm codes
shown by the display and an acoustic signal emitted by a buzzer inside the Operational
console.
When there is an alarm, the
icon starts flashing on the display, the alarm relay is
activated, as well as the internal buzzer and one of the alarm codes is displayed (the code
is alternated with the page normally displayed).
The internal buzzer can be silenced at any time by pressing the "Sound off" key. Press the
SET key (compressors or fans) to reset the audio signal. If an alarm has been silenced
and another kind of alarm is tripped (a different one from the one currently reported), the
audio signal goes off again and the error code will be shown based on the display priority.
There can be two kinds of alarm based on how serious they are:
-
Automatic set (the alarm is automatically reset when the problem is cleared);
-
Manual reset from the keyboard (the alarm is reset once it has been acquired by the
operator via the "Sound off" key).
When the alarm is cleared, the
icon stops flashing and becomes steady to tell the
operator that an alarm with an automatic reset was tripped and is no longer activated. The
display goes back to showing the normal page and the alarm code is no longer shown.
When the "Sound off" key is pressed, the steady
icon turns off. The alarm code with the
top priority tripped is saved and can be displayed (read-only) in the first-level ALL variable.
The view of this variable at the first commissioning (with empty memory) will display ---.
The alarms are displayed in the following order of priority: E0, E0n, E1, E2, EH, EL, EHc,
ELc, EHu, ELu, E8, EF,EC1….EC0, EU1….EU0, EC, Eu, EO5, E7, EP, En, E6.

ALARM HISTORY MANAGEMENT
7.2
The VISION SC600 system can log up to 40 alarm events. To display the codes of the
logged alarms, press the TACITO ALLARME [ALARM OFF] key for at least 3 seconds.
Sector 1 of the LCD display (see par. 5.4) will indicate when the alarms occurred, from the
most recent (0) to the oldest one (39). Sector 2 on the LCD display will indicate the alarm
code, while sector 3 displays the date on which it was saved or the time if occurring on the
same day. The UP and DOWN keys are used to scroll through the logged data, starting
from the most recent one. To reset the logged data, press the SET COMPRESSORI [SET
COMPRESSORS] and SET VENTILATORI [SET FANS] keys together for 10 seconds
during the display stage. After 10 seconds, the instrument will emit an audio signal and exit
the page displayed. If there are no alarms saved in the memory, the system does not
provide access to the display.
To exit the page displayed, press the UP and DOWN keys together for at least 3 seconds.
The instrument exits automatically if no keys are pressed for 30 seconds.
When the instrument is turned on, the “On” code is logged with the relative time of the
event.
