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 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)

General
7.2.1
Mains switch “ON” – no function
•
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, replace the respective component.
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. 7 and 8 of the 8-pole-plug X23 from the control
panel PCB. If voltage is present, then exchange the control panel
•
Check fuse (5A) on the power PCB
•
Disconnected the temperature sensor of the developer bath (X25) and check again
•
Disconnect temperature sensor dryer (X24) and check display again

Drive
7.3.1
Machine does not start automatically
When machine is switched on place a film in the infeed until it reaches the pull-in-rollers. If necessary,
move the film sideward to activate the light barrier. If the display shows two bars with decimal points,
then the light barrier is in order. Check each of the four eyes on the light barrier. Each eye must start the
machine - if not then exchange light barrier. Check the connection of the light barrier. If there is no
reaction on the display then exchange the light barrier, eventually the control unit has be changed.
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.
Developer-temperature button is flashing: see “Developer bath temperature is not reached” see

7.3.2
Machine doesn't stop automatically
•
Display is flashing: Control is in the manual mode. Switch back to Automatic Mode (see 5.2.2)
•
The display continuously shows two bars with decimal points: Light sensors on light barrier are
dirty or the light barrier is defect. Clean with soft cloth. If the need arises dismount light barrier
to clean it. If the switches are defective, the machine can still be used in the manual mode (see
5.2.13)
•
PCB is possibly faulty - then exchange
