Developer Temperature Too Low; Developer Temperature Too Low, Fixer Temperature Too High; Calibration Of Developer Temperature; Film Defects - Protec ECOMAX Manual De Instrucciones

Trouble Shooting

4.3 Developer temperature too low

• Check circulation pump. Air lock in the circulation pump: vent pump (see
page 15). If no circulation can be detected: check wiring of circulation
pump, pump possibly defective.
• Bath is not heated: check temperature safety switch on heat-exchanger.
Check heating element: impedance across the element should reach
approx. 174 W.
• Check temperature sensor (see 4.2).
• If no other error can be detected, the temperature controller may be defec-
tive.

4.4 Developer temperature too low, fixer temperature too high

• Air lock in the circulation pump: vent circulation (see page 15).

4.5 Calibration of developer temperature

Temperature fluctuations can be compensated for by the temperature controller.
The controller is accessible from top. Remove the cover plate above the pumps.
Adjustment of the controller is expained on the drive shaft next to it (see figure)

Film defects

5.1 Films will not dry

• No air comes out of air channel: check fastening of fan impeller, motor may
be defective.
• Cold air comes out of air channel: check wiring of heating element in the
air channel, heating element possibly defective.
• Hot air comes out of air channel, but the film is still not dried to satisfaction.
Check chemicals and film type. If this leads to no solution then the trans-
port speed of the machine can be reduced (see Changing the transport
speed, page 33).

5.2 The film does not transport correctly

• Check the positioning of the racks in the machine and make sure that the
latches are closed.
• Check the roller racks: rollers are correctly seated and do not have exces-
sive clearance, rubber springs are correctly seated, all gear wheels are
installed.
• Motor runs: the worm gear of the drive shaft should be secured with a split
pin to avoid twisting. Check the screws and positioning of the chain and
chain wheel.

5.3 Scratches, pressure marks, dirt on film

• Pressure marks caused due to polluted or damaged rollers. Check rollers
for visible damage. Rubber rollers sometimes swell up. Replace defective
rollers.
