7.3.3
Drive motor does not run
•
Display “E1” or “E3”: see “Error messages” see 5.5
•
If current can be registered on motor, then motor is defect - replace it.
•
Dryer fan runs but no voltage on motor: exchange power PCB.
7.3.4
Disp
l
ay shows error message “E2”
•
Check plugins between main drive motor and power PCB. If “E2”" appears again, then
exchange main drive motor. In rare cases the PCB causes the error (see “Error messages” 5.5)
7.4
Baths
7.4.1
No circulation in bath
•
Circulation pump runs but no circulation can be registered. Air lock in heating and circulation
system. To ventilate: see “1. Test run” 3.6.1
•
Particles in the pump chamber. The pump chamber can be easily opened by removing the
four clips. When closing again ensure that the rubber seal is positioned correctly and not
damaged
•
Pump does not run. Check voltage on the connections X3 and X4 of the power PCB. If no
voltage can be registered, see “Mains switch “ON” – no function” see 7.2.1. If however voltage
can be registered, exchange pump.
7.4.2
Developer bath temperature is not reached
•
No circulation
o
Circulation pump has no current or is defective.
o
Air in circulation system: see “1. Test run” see 3.6.1).
•
Check temperature safety switch on heat-exchanger. For temperatures up to 90°C, the
temperature limiter must have current passage.
•
Check heating element: Current flow resistance should read approx. 66 Ω.
•
Check temperature sensor: Voltage at X25 on the control unit between pin 3 (green) and pin 2
(brown). The value should read 0. 32 V at a temperature of 32 °C.
•
Increase the temperature and check the current on the control unit of clip X13. Voltage should
be between mains and 60 Volts. If this is not the case, exchange the electronics.
7.4.3
Developer bath temperature is higher than the set temperature, display shows two
crossbars, developer temperature button blinks
•
see above
•
Check current on power PCB at clip X13. There may be no current. If current is registered,
exchange electronics.
7.4.4
Developer bath temperature too high or too low (display shows values of
20 °C or 42 °C)
•
Check temperature sensor. Sensor is either not connected or defective.
7.4.5
Calibration of bath temperature / actual bath temperature is different from displayed
value
Differences between displayed temperature and measured value in the developer bath can be
adjusted. An adjustment may be necessary for example after exchanging the bath temperature sensor.
A calibration has to be done, if the difference is higher than +/- 0.5 °C. Adjustment range is +/- 2 °C.
7.4.5.1
Calibration process
1
Switch processor off. While pressing developer temperature button switch machine on. Display
will show developer bath temperature measured by sensor.
2
Measure actual temperature inside developer bath using a calibrated thermometer.
3
At first adjust displayed value in 1-degree-steps using the arrow buttons and. To adjust the
decimal, hold developer temperature button down and press resp. arrow-button.
4
Switch machine off again.
