Enable before clutch cool down expired fault.
Enabling the CES controller before the
cooldown period has expired following a clutch current fault.
Possible causes:
-
Operator error following a brake current fault.
-
Defective brake control board.
231
Communication Fault between the clutch and brake control boards.
The controller has two microprocessors. The master processor handles everything
except for speed and current control. The control processor handles speed and current
control. It accepts speed and run commands from the master control and reports
current and speed values to the main processor several times per second. If no data is
received by the master processor for the programmed time, a control fault is set.
Time = Parameter Group H, Item 23.
Possible causes:
-
Connections between clutch control board “PL2 and brake control board PL-EC
-
Clutch control processor crashed. Cycle power to the control.
-
Defective clutch control logic board.
-
Defective brake control board.
13.3 TROUBLE SHOOTNG 300 LEVEL STOP ON TOP FAULTS
300 level: these faults will cause the CES controller to execute a normal stop upon reaching the top of
the press stroke.
313
Under speed fault.
An under speed fault exists when the tach signal is less than speed
reference for a time and % as determined by parameters H.18 & H.19.
Possible causes:
-
Insufficient torque caused by damaged or reduced capacity of clutch coils.
-
Mechanical binding of press.
-
Clutch current limit set too low.
-
Failed SCR’s
-
Clutch control board not firing SCR’s
-
Loose belts on mechanical CES Drive.
