PRESENT FAILURES
READING
When the “Failure” function is displayed, press the con-
firm button “ ” to display the present failures.
If no failures are currently present, after pressing the
confirm button “ ” the message “End failures” will be
displayed.
The monitored failures are:
Compressor
The machine is locked if the compressor runs non-stop for
more than 24 hours.
Coin mechanism
The machine is locked if it receives a pulse longer than 2
seconds on a validator line or the communication with the
serial coin mechanism does not take place for more than
30 seconds (Executive protocol) or 75 seconds (BDV
protocol).
RAM Data
One or more areas of the RAM contain wrong data which
was corrected with the default values.
The machine will continue to function, but it would be
advisable to initialise as soon as possible.
Probe
The machine is locked after 5 minutes if the internal
temperature sensor is disconnected; the display will indi-
cate a temperature of -11° C.
The machine is locked after one hour if a sensor short
circuit is detected; in this case the display will indicate a
temperature of +41° C.
Motor errors
With this function the failed motors are displayed for
approximately 1 second.
Scrolling through all failed motors is automatic.
Note:
By restarting the machine any blocked motors are de-
tected as not present.
Dispensing compartment lock
When the function “unlock compartment with dispensing”
and the parameter “out of service if open” are active, the
machine will lock if the locking device of the dispensing
compartment remains blocked when closed or it does not
close within the programmed time.
Motors status
This function is used to read the last failure that occurred
in each spiral, even if the machine configuration has an
empty position.
A motor can be in one of the following conditions:
- motor functioning;
- motor not present; when the motor is not detected at
machine start-up.
- motor disconnected; when a motor detected at ma-
chine start-up is not detected during a selection.
- motor blocked; when the positioning button is not
operated within the “timeout”.
- empty spiral; when, with the dispensing control in-
stalled, no dispensed product is detected.
Note:
By restarting the machine any motors with errors are
detected as not present.
RESET
By confirming this function all current failures will be reset.
