Trouble Shooting
7.1 Algae
7.1.1 Excessive algae growth in water tank
Algae growth inside the water tank is not only annoying, it causes increased cleaning work and leaves
residue on the films. When algae growth increases, countermeasures are in demand:
• When work has been completed at the end of the day, drain water out of the machine
• Clean dryer-water rack regularly. Use soft sponge and soap to remove residue from the rollers
• Install a particle filter system in the fresh water supply for the processor
• If water tank overflows due to algae growth blocking the overflow hose, then the overflow
hose can directly be connected to the connection at the water tank inside the machine
• If no other solutions can be found, then usage of Anti-Algae-Agents can be a great
improvement (automatic dispensers work the best). However, it is known that cleaning agents
containing chlorine may corrode rubber rollers and high-grade steel in the tank area (check
before use)
7.2 General
7.2.1 Unit does not switch on
• Ensure that electrical socket has power supply
• Check machine fuse in main switch
• While power switch is on, check the following components: Voltage on contact of main switch
- If there is no voltage: - change main switch. Check input voltage at electronics. If the voltage is
normal, replace the electronics. If there is no voltage: check the cable
CAUTION!
For replacement exclusively use PROTEC gold cap fuses. These
fuses are optimized for use under existing conditions.
7.2.2 No display but circulation pumps run
• Check input voltage of 5 V at the contacts no. 1 and 8 of the 8-pole-plug X18 from the control
panel PCB. If voltage is present, then replace the control panel
• Disconnected the temperature sensor of the developer bath (X15) and check again.
7.3 Drive
7.3.1 Film transport does not run, film processing has started
• Display “E1”: see “Error messages” see 5.4
•
Check screwing of chain wheel on motor- and driveshaft.
7.3.2 Machine does not start automatically
• When the machine is switched on, insert a film into the feed. If the display shows two bars with
decimal points, then at least one of the film detection switches is in order. Check the function
of both switches, replace as needed
•
The display shows “E1”: The cover switch is not actuated by the latch on the cover. Cover
switch has no current passage when activated: Replace
7.3.3 Machine doesn't stop automatically
• Display is flashing: Control is in the manual mode. Switch back to Automatic Mode (see
5.2.12.2)
• The display continuously shows two bars with decimal points: Actuator of the film detection
switch is jammed. Readjust the switch or replace it. If the switches are defective, the machine
can still be used in the manual mode (see 5.2.12.1)
• The power output section may be defective, if so replace it
