5.12.5 Monitoring of the medium pressure
The parameters required for the monitoring of the medium pressure can be configured using the menu 3-3. The
parameter
MP OFF xxx sets the maximum permissible medium pressure. If the pressure exceeds the specified
limit value, the system is immediately shifted down to a specified number of compressors (parameter
Nr.Comp.MP-Al ). The High MP message is sent. The parameter MP ON xxx b specifies the pressure for which
the compressors disabled by MP OFF are enabled again.
5.12.6 Monitoring of the medium pressure valve
If the medium pressure (MP) deviates from the setpoint by more than 2 bar for a period longer than 10 minutes,
the controller sends the message
Alarm MP-Valve .
In the event of a fast unload and with all compressors idle, the message is reset.
5.12.7 Monitoring of the fan motor overload cut-out
The fan motor is monitored by the motor overload cut-out. The auxiliary contact is open in the alarm state (no
signal at the input of the controller). The alarm message "
Mot. cutout Fxx " is sent if the motor overload cut-out
trips.
The motor protection monitoring can be influenced with the following parameters:
