INPUTS/OUTPUTS menu - Compressor magnet circuit breaker flow switch digital inputs
Visualisation on unit display Index Display/Parameter
A Inputs/Outputs: Indicates the state of the different entries/exits.
B Master: indicates the type of data displayed; the displays can be:
• Analogue inputs;
• Digital inputs;
• Digital outputs;
C 05: indicates the status of the flow switch positioned on the
evaporator, the status of this input can be one of the following:
• Closed = normal functioning;
• Open = minimum water flow rate threshold exceeded at the
evaporator (Flow switch alarm);
D
06: indicates the status of the compressor magnet circuit breaker
indicated, the status of this input can be one of the following:
• Closed = normal functioning;
• Open = the compressor load has exceeded the maximum
threshold (Compressor magnet circuit breaker alarm);
