6.4.1 Alarm Auto Reset
In this menu, the behaviour of the CPSm in case of faults can be adjusted. Here, two settings for each
fault case are possible. AUTOMATIC reset (mask bit = 0) or MANUAL reset (mask bit = 1).
In the AUTOMATIC position, the fault indication is reset and the control continues to operate, when
the fault is not present any longer.
In the MAN position, indication of all faults is maintained (with the exception of short-term high water).
In order for the controller to continue to operate, all faults must be reset on the controller.
Decide for each fault whether or not an automatic reset should be effected and determine the
corresponding mask word as described above.
A recommendation for adjusting is given in the above table in the column "auto" ( x = automatic reset;
n = no automatic reset; - no recommendation, depending on application).
Security Note: The T2-alarm (thermo contact with higher
tripping temperature) of controllers used in Ex-endangered
areas should not be set to "Auto reset" .
