Troubleshooting
5-17
Problem: The following errors indicate failures on the WPC 2000 Main Processor board or
the DSV/Lockout Relay board. Error codes F70, F71, F72/H72, F73/H73, and
F76/H76 indicate failures with the DSV driver logic on the Main Processor board.
Codes F74/H74, F75/H75, and F77 indicate failures with the relays on the DSV/
Lockout Relay board. F78 indicates an issue with the poppet position sensors in
the DSV valve itself.
Remedy:
Press Reset/Select. If the error persists, contact Wintriss Tech. Support for
assistance or replacement of either board.
Loss of Rotation
Problem: The Dual Safety Valve (DSV) has been activated, but the resolver did not start
rotating within the Start-time Limit set on the WPC 2000.
The Start-time Limit setting may be too short. Alternatively, the drive belt on the
resolver may be loose or broken, and the resolver may not be turning continuously
with the press crankshaft, or have stopped turning altogether. Also, the resolver
may be defective.
Air pressure to the clutch may be low, or the clutch may be bad, resulting in no
movement of the crankshaft (and resolver) even though the DSV is energized. In
addition, an internal WPC 2000 problem could have occurred.
Remedy:
Check the Start-time Limit setting, and re-initialize if necessary (see Initializing
Only the Start-time Limit, page 3-5). Check the resolver and resolver drive, and
replace the resolver if necessary. Check the clutch and repair if necessary. If these
solutions do not work, contact Wintriss Tech. Support.
