Settings 35
Alarm Mode 0: Warning-Alarm
Output 1 Output 2
Turns on When >Lower >Upper
Intended Function Warning Alarm
This allows the ICM to switch external warning lights or alarms. Output 1 is the
"Warning’’ output, switching on if any of the Lower limits are exceeded. Output 2
is the "Alarm’’ output, behaving similarly for the upper limit.
Alarm Mode 1: Clean-Dirty
Output 1 Output 2
Turns on When ≤Lower >Upper
Intended Function Clean Dirty
This could be used in a cleaning system that attempts to maintain a cleanliness level
by switching a pump on and off.

the lower ("Clean’’) limit. This could be used to stop a cleaning pump.
Output 2 is the "Dirty’’ output, coming on when the result is greater than the upper
("Dirty’’) limit. This could be used to start the cleaning pump.
Alarm Mode 2: Green-Amber-Red
Output 1 Output 2
Turns on When <Upper >Lower
Intended Function Green Red

result – in a similar way to the built-in one. Output 1 ("Green’’) is turned on when
the result is less that the upper limit. Output 2 ("Red’’) is turned on when the result
