APPENDIX B: PROBLEM SOLVING
In this appendix, several problems are included that can occur when the F093-P is going to be
installed or while it is in operation.
Tachometer does not generate pulses:
Check:
Signal selection SETUP - 61,
Pulse amplitude (par. 4.4.2. / 4.4.3.),
Tachometer, wiring and connection of terminal connectors (par. 4.4.2. / 4.4.3.),
Power supply of Tachometer (par. 4.4.2. / 4.4.3.).
Tachometer generates "too many pulses":
Check:
Settings for running hours and Engine speed: SETUP 11-14 and 21-27,
Type of signal selected with actual signal generated - SETUP - 61,
Sensitivity of coil input - SETUP - 61 and par. 4.4.2 / 4.4.3.
Proper grounding of the F093-P - par. 4.4.1.
Use screened wire for Tachometer signals and connect screen to the “
┴
“ terminal.
Engine speed displays "0 / zero" while there is RPM (running hours is counting):
Check:
SETUP 22 / 25: are the K-factor and time unit correct?
SETUP 26 / 27: The unit has to count the number of pulses according to SETUP 26 within
the time according to SETUP 27. Make sure that 27 is set to 10.0 seconds for example : the
result is that the unit has at least 10 seconds time to measure the number of pulses
according to SETUP 26.
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.
0003: error 1 and error 2 occurred simultaneously
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.
