7 TROUBLE-SHOOTING
7.1 ALARMS MANAGEMENT
The “OMEGA” electronic card is a powerful control logic unit which signals possible
machine troubles by means of alphanumeric messages visualised on the display; the
technician shall understand them to quickly find the reason of this trouble.
MESSAGE
DESCRIPTION
REMEDIES
EME
EMERGENCY
The door is open or the safety grid on the hopper is not
completely lowered.
An intermittent beep is released.
Make sure that the door
is closed and the safety
grid on the hopper is
lowered.
TER
MOTOR
THERMAL
CUTOUT ALARM
When a motor thermal cutout is triggered, it is followed by
the blinking of the led TER and by the release of an
intermittent beep.
After checking the
machine, press STOP to
restore correct
functioning.
EPO
STORED DATA
ALARM
When the machine is started up, the microprocessor checks
the data stored in the EPROM memory: if this data are not
correct EPO will appear on the display, followed by the
release of an intermittent beep.
Send for a technician.
EPI
MEMORY ALARM
If, during normal functioning, the memory is not
acknowledged, EPI will appear on the display, followed by
the release of an intermittent beep.
Send for a technician.
LI
POWER SUPPLY
ALARM
If, during normal functioning, the voltage is too low, LI will
appear on the display, followed by the release of an
intermittent beep.
Check mains voltage
and machine power
supply.
OUT
USCITE MODULE
ALARM
If, during normal functioning, the output control module is
faulty or if it is not acknowledged, OUT will appear on the
display, followed by the release of an intermittent beep.
Send for a technician.
TA
TA ALARM
If, during normal functioning, an anomaly of the current
transformer occurs, TA will appear on the display, followed
by the release of an intermittent beep.
Send for a technician.
UTA
TA MICRO-
PROCESSOR
ALARM
If, during normal functioning, an anomaly of the
microprocessor controlling the consistency calibration
occurs, UTA will appear on the display, followed by the
release of an intermittent beep.
Send for a technician.
