generated after a configurable time delay. The priority of the signal can be configured High HP (menu 3-7). No
signal is generated In the heat recovery mode. In the event of any pending HP fault, no additional compressor
output stages are switched on.
5.12.4.2 High Pressure Monitoring Too Low
The system high pressure should be in a specific range during normal operation of the system. In addition to
the high pressure too high monitoring, the high pressure is also monitored for undershooting a lower limit value:
In the event of undershooting Low HP , the signal HP too low is output after expiry of a configurable signal delay
time using the parameter Del. HP too l. (menu 3-3). The signal is transmitted according to priority preselection.
This signal is not output in the case of measuring circuit errors of the HP transmitter. The HP too low signal has
no effects on the control and regulation processes.
5.12.4.3 Monitoring of the HP Valve
If the output opening degree for the HP valve is different for longer than the configurable alarm delay setpoint
Del.Dev.OD.HP-V by more than the configurable setpoint Max.OD.Dev.HP-V percentage difference from the
real HP valve opening degree read back via the analogue output 2 (terminals 38...40), the controller sends the
message
Error.OD.HP-V (Default-Prio. 2). The message has no influence on the control and regulation
processes.
5.12.4.4 Monitoring of the HP Control Error
The control error of the high pressure regulation, i.e. the difference between the actual value and the setpoint,
is monitored whether this exceeds a configurable threshold value for a configurable time. In this case, the
controller generates the message
Deviation HP . The following diagram shows the monitoring:
