The High and Low Pressure Alarm switches on this model have been wired to allow Volt Free indication of Faults.
If Power Interruption of the associated Boiler / Chiller plant is required, the 240v 50Hz power supply for the associated
Boiler / Chiller plant should be routed as follows;
Interlock Circuit In
- Term 2
Link Wire Required - Terms 1 & 5
Interlock Circuit Out - Term 6
In this manner if one of the Alarm Switches are activated, the power supply to the associated Boiler / Chiller plant will be
interrupted.
