6.5.7 Set up 1 – Alarm
The CPM 153 continuously monitors the most important functions. If an error occurs, an
error message (list of all error messages s. page 93) is set, which can trigger one of the
following actions:
• The fault signalling contact is made active
• Current output 1 outputs the set error current (2.4 or 22 mA)
Current output 2 outputs the set error current, if it has not been configured for the
controller function.
• ChemoClean cleaning is started
In the list of error messages on page 93 you can see how the error numbers are
assigned according to the factory settings. However, in the "ALARM" menu, you have
the option of outputting the error messages individually to the alarm relay, the current
output or as a cleaning trigger.
Note!
Please refer to for the complete list of possible error messages page 93.
To enter the menu, proceed as follows:

Note in display:
Error current is in the measuring current range. When
the current range is "0 ... 20 mA" and "Min" is selected
under Alarm in Field H1.
Recommended combinations:
Current range 0...20 mA and error current max (22 mA)
or
Current range 4...20 mA and error current min (2.4 mA)
