Fig. 3−163 Monitor outputs of the monitoring system (MONIT)
Function
The MONIT outputs switch to HIGH level if one of the monitoring functions responds.
The digital monitor signals respond dynamically, i.e.
l depending on the state of the monitoring function, but
l independently of the selected fault reaction (e.g. TRIP).
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).
) Note!
l With appropriate signal conditioning, the MONIT outputs can be used to locate
the cause of malfunction (e.g. by storing the MONIT output signal via the FLIP
function block).
l More detailed descriptions of the monitoring functions / error messages can be
found in the chapter "Troubleshooting and fault elimination".
