Mercury Coldroom Panel Installation Guide
Probe and Alarm inputs
Note: When wiring in the probes to the connector, ensure that the 3 wires fitted to the probe connector (not shown on the diagram below) are
not moved and remain firmly connected. These wires are used for the external digital inputs; door-open and entrapment. The resistors for
the digital inputs are already present on the PCB and therefore external resistors are not required to signal door-open and entrapment
alarms. The user only needs to configure the jumper switches (below), to identify what type of probe is being used when using the
additional switched resistor functions ‘Case Clean’ and ‘Plant Fault 1’ (see Switched Resistor Values).
