Fault clean oil outlet: apa yang harus dilakukan?

Penyebab: No pressure build-up or pressure drop at the clean oil outlet. Tindakan: Check separator per its manual; acknowledge and restart

Fault feed temperature: apa yang harus dilakukan?

Penyebab: Feed outside min/max temperature. Tindakan: Correct heater/feed temperature

SHORT-CIRCUIT TERMINAL 19/39: apa yang harus dilakukan?

Penyebab: Faulty displacement/filling water valve or wiring. Tindakan: Check connection, replace valve, press Enter

Display lit but no text: apa yang harus dilakukan?

Penyebab: EPROM fitted wrong way round or not programmed. Tindakan: Check EPROM number TVWS7X4A0-255

ERROR WATCHDOG: apa yang harus dilakukan?

Penyebab: Control program reset after abnormal operation. Tindakan: Acknowledge; if it persists after power cycle replace the unit

Westfalia VESC-1

Unit kontrol separator

The Westfalia VESC-1 control unit runs the separation, sludge discharge (partial and total ejection) and displacement programs of a self-cleaning separator and monitors it. Inputs include motor fault, clean-oil outlet pressure switch, feed temperature min/max switches, feed pump control and sludge tank level switches; outputs drive the feed, displacement/filling water and operating water valves, the sludge pump, a collective alarm and a klaxon. The manual and parts list explains the inputs and outputs, programming of times, operation (start, separation stop, separator off), monitoring and alarms, short-circuit and internal fault finding, and the watchdog.

Prosedur perawatan

Stopping separation

Press key 0 in separation mode: the unit runs waiting, displacement, waiting after displacement and speed recovery, then ejects with minimum product loss. hlm. 37
Pressing 0 during ejection interrupts the program at once. hlm. 37
If the motor starter is switched off with the feed valve open, a total ejection is made automatically. hlm. 37

Clearing an alarm

Read the fault text on the display (e.g. clean oil outlet, feed temperature). hlm. 37
Eliminate the cause, press Enter to acknowledge, then press I to restart separation. hlm. 37
