General Information

PL-M2000 Rooftop Controller

Description

The ProLon PL-M2000 RTU Rooftop controller is a microprocessor-based controller designed to operate rooftops or other mechanical HVAC systems. It uses PI (Proportional-Integral) control loops and acts as a master when used on a network with ProLon zone controllers.

General Behaviour

Although fully configurable, the ProLon M2000 Rooftop controller uses pre-established control sequences or ’’profiles’’ to operate specific HVAC equipment with dedicated output functions. These can be fully optimized to obtain the best results for each type of system. Numerous parameters enable the modification or fine tuning of the fan, the cooling outputs, the action of the heating outputs (On-or-Off / pulsed / modulating), the bypass or VFD and outside air dampers, the CO2 levels, the proportional bands, integration times, differentials, operational ranges, setpoints and a whole range of limits and safeguards.

The various programming options also allow the user to modify the schedule, unoccupied mode settings, morning warm-up and supply air pre-heating sequences as well as the network demand control strategy best suited for the building space it is controlling. All these parameters can be accessed by using the

ProLon Focus software.

REV. 6.1.8 / PL-HRDW-RTU-M2000-C/F-EN 4

Operating Sequence

General

The ProLon M2000 RTU Rooftop controller receives readings from five different temperature sensors: outside air, return air, supply air, mixed air and zone air. In addition to the temperature sensors, it also has inputs for the static pressure, CO2 levels and proof of fan. It operates on a configurable schedule using an internal real time clock. Also, as a Master device, it receives data from the zone controllers sent over the network bus. The controller then analyzes all the data and demands sent by the zones and commands the appropriate outputs to respond accordingly, within parameters set by the temperature sensors and other safety limits. The Master sends back information on its network such as supply air temperature, occupancy status and other relevant data for the zone controllers to use.

Occupied Mode

The controller operates the fan. When there is a cooling demand from the zones, the Rooftop controller will activate the cooling outputs as long as all temperature limits, delays and other related parameters are respected. Once the demand is satisfied, the outputs are deactivated within the prescribed minimum on/off time delays.

When there is a heating demand from the zones, the Rooftop controller will activate the heating outputs as long as all temperature limits, delays and other related parameters are respected. Once the demand is satisfied, the outputs are deactivated within the prescribed minimum on/off time delays.

When the CO2 levels become too high, the Rooftop controller will open the outside air damper as long as all temperature limits, delays and other related parameters are respected. Once the CO2 levels return to normal, the outside air damper returns to its previous position.

When there is no cooling or heating demand from the zones, only the fan is enabled. If the heating equipment permits, a supply air pre-heating sequence may be enabled. This allows cold mixed air to be heated to a more comfortable level for subsequent use by the zones for ventilation.

Unoccupied Mode

The fan can be configured to operate in intermittent mode. When there is a cooling or heating demand from any single zone, the Rooftop controller will activate the fan and the necessary cooling or heating outputs as long as all temperature limits, delays and other related parameter are respected. Once the demand is satisfied, the fan and any cooling/heating outputs are deactivated within the min. on/off time delays set.

During the unoccupied period, the Rooftop controller can be driven by the highest demand on the network and will operate the fan and relevant outputs accordingly.

HAND/OFF/AUTO Switches

Each output on the M2000 has a dedicated switch that lets the user manually override the activity of the output. “HAND” mode (switch at rightmost position) fully activates the output (24 VAC for digital outputs,

10VDC for analog outputs). “OFF” (switch at center) deactivates the output and “AUTO” (switch at left) returns control of the output to the program in the M2000’s microchip.

Jumpers

The M2000 has jumpers that are externally accessible (see Figure 3), as well as jumpers that are on the lower internal board (see Figure 4), that allow for configuration of various hardware elements.

Input and Output Identification

All the inputs and outputs of the M2000 use pluggable screw type terminal blocks with elevator style clamping, which make connections easier and more secure.

For incoming communication from a remote computer or network controller, dual RJ45 type connectors are available in parallel with screw type terminal blocks. The RJ45 connectors allow the use of premade

CAT5 cables for simple plug-and-play RS485 communication. These RJ45 connectors follow the Modbus pinout specification for RS485 communication.

Addressing Dipswitch Configuration for Network Communication

For proper communication, a unique address must be configured on each controller by setting the first

7 switches on the addressing dipswitch bloc to the desired value. The dipswitch bloc is located on the front section of the PL-M2000 RTU.

These switches are numbered from 1 to 7 and represent a binary value from 1 to 64 (1, 2, 4, 8, 16, 32, and

64 respectively). The last switch (#8) is reserved. The value of each switch that is in the ON position is added together to form the numerical address of the controller.

The example in Figure 9 shows the switches 1, 2 and 4 in the ON position. Therefore, the corresponding values are 1, 2 and 8, giving an address sum of 11.

The ProLon network allows a maximum of 127 addresses; therefore 127 controllers.

REV. 6.1.8 / PL-HRDW-RTU-M2000-C/F-EN 10

Inputs

Temperature Sensors

The M2000 Rooftop controller has four analog inputs that monitor outside air, supply air, return air and mixed air temperatures (see Figure 10) and will integrate these readings into its control sequence. The sensors used are standard 10k type thermistors that share a single common connection.

Alternatively, the supply air temperature can be retrieved from a zone controller that has its own supply sensor and belongs to the M2000’s network.

The outside air temperature can be also be provided by an alternate source. If a network controller is present on the network, it can retrieve the outside temperature reading from one controller and distribute it to any other controllers on the network.

REV. 6.1.8 / PL-HRDW-RTU-M2000-C/F-EN 11

Room Sensors

The M2000 RTU can receive the setpoint and temperature from a specific room when a PL-RS analog thermostat is connected to it. The M2000 will then automatically integrate this information into its control sequence. The setpoint may also simply be set by software. The PL-RS series room sensors are connected using a 3-conductor cable (see Figure 11).

Proof of Fan

The M2000 RTU has an analog input dedicated to the proof of fan signal. Please refer to Figure 12 to see how to correctly connect it to analog input 7. To indicate proof of fan, the contact must be closed. If no proof of fan signal is available, you must short analog input 7, or else the controller will interpret the absence of signal as a fan malfunction and no heating or cooling action will be taken.

Dry Contact for Clogged Filter or Schedule Override

Analog input 4 on the M2000 RTU can also be configured as a dry contact input for either a clogged filter sensor or as a schedule override input. Please refer to Figure 13 to see proper connection.

• Clogged filter sensor: To indicate that the filter is clogged, the contact must be closed.

• Schedule Override: Closing the contact causes the M2000 to immediately return to occupied

mode from unoccupied mode. The M2000 remains in occupied mode as long as the contact is held

closed. If it was already in occupied mode, there is no change.

Static Pressure and CO2

Analog inputs 8 and 9 on the M2000 rooftop controller are dedicated to the CO2 and static pressure sensors, respectively. By default, a 4-20 mA signal is expected for the CO2 input and a 0-5 VDC or 1-5 VDC signal is expected for the static pressure input. However, this can be modified using the internal jumpers

(see p.8). Please refer to Figure 14 for correct wiring.

Outputs

The M2000 Rooftop controller contains 8 customizable outputs; five triac ON/OFF outputs (24VAC) and three analog outputs (0-10VDC). Output configuration is performed via the ProLon Focus software.

An integrated resettable fuse protects each of the outputs of the M2000 against current surges and short circuits. This protection will cut the current to the output as soon as an overload condition is detected.

The fuse is a round, yellow-coloured PTC that will change to orange and heat up on an overload condition. Once power has been removed from the M2000, the fuse will cool down and automatically reset. Fix the faulty wiring and you will be able to activate the output once again.

Typical Connection of Triac Outputs 1 to 5

On the M2000 Rooftop controller, all triac outputs produce a 24 VAC live voltage when activated. Note that all output voltages originate from a single voltage supply: the equipment’s transformer. Consequentially, only the live side of the output connections are usually needed; these are on the top row (see figure

15). The bottom row is the common (GND).

Typical Connection of Analog Outputs 1 to 3

For all analog outputs, the common is found on the bottom row terminal blocks, and the active signals are found on the top row terminal blocks (see Figure 16). Analog outputs 1 can be configured to modulate a 0-10 VDC load, to pulse a 0 or 10 VDC triac relay or to control a 10 VDC On/Off relay. Analog outputs 2 and 3 can only modulate a DC load (0-10 VDC or 2-10 VDC).

DMUX-4J Connection on Digital Output 2 for 3 or 4 Stage Cooling

When 3 or 4 stages of cooling are required, the M2000 Rooftop controller must be equipped with a

DMUX-4J. The DMUX-4J input is only connected to Digital Output 2 on the M2000 Rooftop controller.

The DMUX-4J must be configured to “Sequenced Relay Control” with a 1 second pulse resolution. The

“Triac Input Selection” jumper must be set to normal signal input and the “Power Type Selection” jumper must be set to AC power. The DMUX-4J outputs are then connected to the rooftop unit (see figure 17).

Each of the DMUX-4J outputs have connections for “Normally Closed” and “Normally Open” operation, so use the connection that is compatible with your rooftop unit. For more information on the DMUX-4J, consult the Specification Sheet and the Installation Guide for the DMUX-4J.

Power Source & Network

Power Source

The M2000 controller is powered by the HVAC equipment’s 24 VAC power supply (class 2) by connecting the common (’’C’’ wire) to the "COM" terminal block and the live (‘’R’’ wire) to the "24 VAC" terminal block

(see Figure 19). The common for all inputs and outputs is the same as the power source’s common. All output power sources also originate from the HVAC equipment’s power source.
