01508 MRE: "Too high negative ASV val. in run"
01509 MRE: "ASV init. pulse not detected"
Possible cause
See error code 01506
Incorrect system configuration (DOCMEM instead of SETMEM v.v.)
Too low PHD light intensity setting
Dirty PHD diaphragm
Defective PHD
Actions
See error code 01506
Correct system configuration
If the PHD is involved, it can be checked, when there is enough light in the environment,
by removing of the engine back-cover; if the problem still occurs the
PHD is not involved
Possible cause
Drum has a short cut to ground
Bad connection between ASV-probe and CPU-IO
Bad connection between CPU-IO and SSR-PBA or SSR-PBA and OPC drum
No 24V supply to ASV-probe
Defective compensation voltage supply unit
Defective ASV-probe
CPU-IO defect
Actions
Remedy the drum short cut
Check the concerning connections and the wiring
Check/replace the concerning parts
Aren't you glad you asked.....If the drum is over a mil consider replacing it. When was the last PM? There are sliding contacts, motor side, on the end of the drum that could be dirty. You really need a technician to go through the machine......
