Alarm Mode 0: Warning-Alarm
Output 1
Output 2
Turns on When
>Lower
>Upper
Intended Function
Warning
Alarm
This allows the CMS 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.
Output 1 is the "Clean’’ output, coming on when the result is less than or equal to 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
This mode encodes the result in such a way that the internal alarm relays can be used to drive an external remote
3-colour LED indicator. This is a special type of LED containing both red and green emitters, which could be
mounted in a control panel. This external LED will then turn green / amber / red according to the test 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 is greater than the lower limit. If the result is in between, both
outputs are turned on and the LED colour will be amber (i.e. a mixture of red and green light).
Alarm Mode 3: Particles-Water
Output 1
Output 2
Turns on When
Cleanliness>Upper
Water>Upper
Turns off When
Cleanliness ≤lower
Water ≤lower
Intended Function
Cleanliness Alarm
Water Alarm
This is used when separate alarm outputs are needed for particles (cleanliness) and water content.
This mode is able to use both upper and lower limits such that the outputs have ``hysteresis’’. If only the upper or
lower limit is required, then both upper and lower limits should be set to the same value.
Alarm Mode 4: Continue-Clean
Output 1
Output 2
Turns on When
>Lower
≤Lower
Intended Function
Continue Testing
Stop Testing / Clean
This is used for a "cleaning" application where a signal is needed to stop testing (for example to stop a pump or
signal an external controller).
