Description
Power supply
Single phase version: GND, N, L1 - 230V ± 10% - 50/60 Hz
Three phase version: GND, N, L1, L2, L3 - 400V ± 10% - 50/60 Hz
Output motor supply - (factory wiring)
Remote Stop/Start via normally open voltage free contact (factory default joint)
Maximum performance through normally open voltage free contact
Min/Max: Normally open voltage free contact min/max speed activation if equipment is
configured in MIN/MAX operating mode. The maximum speed is 100% and minimum is
40%.
Night: Normally open voltage free contact that reduces selected setpoint to 50% and,
consequently, reduces the motor speed. Active function in COP, CAV and VAV modes.
Switched alarm relay
AI3 Analog input 0-10V or 4-20mA. +24V output (100mA max.)
AI2 Analog input 0-10V or 4-20mA. +24V output (100mA max.)
AI1 Analog input 0-10V or 4-20mA. +24V output (100mA max.)
Motor tachometer - (factory wiring)
0-10V motor regulation master output - (factory wiring)
0-10V regulation slave output to other equipment. By factory default, slave output will
be same as equipment regulation speed. Parameter only modifiable through Modbus
communication.
Modbus RS485 communication connection and +12V power supply (300mA max.)
