APPENDIX B: PROBLEM SOLVING
In this appendix, several problems are included that can occur when the F124-P is going to be
installed or while it is in operation.
The pass code is unknown:
If the pass code is not 1234, there is only one possibility left: call your supplier.
ALARM
When the alarm flag starts to blink an internal alarm condition has occurred. Press the "select
button" several times to display the 5-digit error code. The codes are:
0001: irrecoverable display-data error: data on the display might be corrupted.
0002: irrecoverable data-storage error: the programming cycle might have gone wrong: check
programmed values.
The alarm condition will almost certainly be handled internally and if all mentioned values still appear
correct, no intervention by the operator is needed. If the alarm occurs more often or stays active for
a longer time, please contact your supplier.
0004: current flow B is outside its range as specified with setting 23 and 24.
0008: internal setpoint out of range. Ratio setpoint x flow A is outside flow B range.
Example: ratio setpoint 50%, flow A 60.000 L/hour requires 30.000 L/hour for flow B. If this
value is outside setting 23 or 24 the error is generated.
Above alarms can only be resolved by changing the configuration settings.
If several alarms are generated simultaneously, the alarm values are added together.
(e.g. 0003 is error 0001 and error 0002).
APPENDIX C: COMMUNICATION VARIABLES
The F124-P can be supplied with Modbus communication.
Available on request – please contact your supplier.
