When operating voltage is applied, the MPA22 automatic burner-control
system performs a startup test and then displays "OFFUPr".
This means that no setup procedure has been completed as yet.
The MPA22 automatic burner-control system has separate setup procedures
for each operating mode and characteristic-map memories which are backed
up separately for each operating mode.
A "P" is displayed while setup is in progress. This mode has a 30-minute timeout;
the timer is reset each time you press a button on the touch-sensitive display.
If the timeout expires a safety shutdown is triggered and the "OFFUPr" message
reappears in the automatic burner-control system's display.
The purpose of this timeout is to prevent incomplete setup causing the burner
to remain on for a prolonged period of time.
All safety functions are activated during the setup procedure, just as in normal
operation. The only difference is that the servomotors can be brought to the
limits specified in the setup mode. As in normal operation, flame failure, air-
pressure monitor failure or a fault in servomotor drive and feedback, or other,
similar faults result in a fault-triggered or safety shutdown.
Setup has to be repeated if a fault-triggered, safety or controlled shutdown occurs
during the setup procedure. The values entered beforehand are retained, on
condition that they pass the plausibility check which takes place on startup.
You must enter a password before you can set the parameters of the MPA22
automatic burner-control system.
Consult the operating instructions for the burner connected to the
MPA22 for detailed settings.
The first step is always to set the automatic burner-control system to setup
mode: Simultaneously press buttons "1" and "2".
A prompt asking you to enter the password appears on the display:
