Fault Message
Probable cause
Action
Type
CHECK PHOTC.FAULT
Ejection Check photocell
obstructed or malfunctioning
according to the space limit set
on CPMA or to the limit value
PAT (with PAT>1)
Remove the obstruction condition or check the correct
functioning of the photocell
Check that there have been no contiguous packages
in transit
Check that no product has accumulated on output due
to a stop of the downstream system
Check that the CPMA space limit is adequate for the
application and in any case greater than the length of
the package
Check that there have been no multiple spurious
readings from the Synchronization photocell and, if
needed, increase the PAT parameter value
Sensor connected to EJECTION
CHECK input faulty or
disconnected
Check the sensor mechanical and electrical
installation and its correct activation
In absence of the installed sensor, deactivate the
diagnosis (CPMA=0)
If the problem persists, contact Assistance Service.
SYNC/CHK PH.FAULT
Failed reading of the Ejection
Check photocell according to the
reading of the Synchronization
photocell Sincronizzazione (with
PAT=1)
Failed reading of the
Synchronization photocell
according to the reading of the
Ejection Check photocell
Sincronizzazione (with PAT=1)
Check that tha package will be correctly detected from
both photocells
Check that the speed value is set to the actual transit
speed (see BS, KT)
Check that the encoder is set to correctly read the
actual transit speed (see DI, KE). In case of
programmable encoders, check that the number of
pulses per revolution is set equal to the one set on KE.
If needed, increase PDA value, compatibly with the
application.
In case of multiple readings due to the packs shape,
adjust PML and GML parameters opportunely or, if
necessary, set PAT>>1
Sensor connected to
PHOTOCELL or EJECTION
CHECK input faulty or
disconnected
Check the sensor mechanical and electrical
installation and its correct activation
In case the sensor connected to EJECTION CHECK
or both sensors are not connected, deactivate the
diagnosis (PAT=0).
If the problem persists, contact Assistance Service.
ENCD.FRQ.TOO HIGH
Speed measured by Encoder is
above BM (
) or higher than
1.3 BM (
)
On systems with
check that the speed
operative range is compatible with the values of BL
and BM parameters.
Check that the encoder is set to correctly read the
actual transit speed (see DI, KE). In case of
programmable encoders, check that the number of
pulses per revolution is equal to the one set on KE.
If the problem persists, contact Assistance Service.
