Function
The MONIT-outputs switch to HIGH level if one of the monitoring functions responds.
The digital monitor signals respond dynamically, i.e.
z depending on the state of the monitoring function, but
z independent of the selected fault reaction (trip, fail-QSP, ...).
Example
MONIT-LP1 (motor phase monitoring) responds if a cable disruption is detected in a motor
connection phase, although the fault reaction of LP1 is set to ”Off” (C0597 = 3).
Tip!
z Only with a corresponding signal conditioning it is possible to use the MONIT-outputs to
detect the cause of malfunction afterwards (e.g. storing the signal by using function block
FLIP).
z A detailed description concerning monitoring /fault messages can be found in the chapter
”Troubleshooting and fault elimination”.
