Westfalia VESC-1

分油机控制单元

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.

保养规程

Stopping separation

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

Clearing an alarm

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