SmartPAC 2 User Manual 1126700
Fault Messages 7-5
Remedy: Check the wiring and installation of the resolver and position sensor (see
Installing the Resolver, page 2-10 and Installing the Position Sensor
(Optional), page 2-37). If shaft diameter is the problem, mount the
magnet on a smaller shaft. If a position sensor is not installed, check to
make sure that the POSITION SENSOR setting in Initialization is
DISABLED (see Position Sensor Mode, page 4-3).
If none of the above procedures prevents this message from displaying,
the sensor may be bad. Try another sensor if available. Otherwise, call
the factory for help. Do not run the press until the problem is solved.
E-Stop errors
Explanation: If the word “ESTOP” appears in a message, one or both of the emergency
stop relay circuits are not working satisfactorily and may be defective.
Remedy: Check both stop relay circuits. To reset SmartPAC 2, turn the unit off,
then on again. (You cannot use the RESET key to reset this error.) If the
error recurs, contact Wintriss Tech. Support.
“Inboard ram test failure”
Explanation: Something is wrong with the SmartPAC 2 main processor board. The
board may need to be serviced or replaced.
Remedy: Try turning the power off, then on again. (You cannot use the RESET key
to reset this error.) If the message continues to appear, contact Wintriss
Tech. Support for assistance or replacement of the board.
“Resolver signals incorrect” or “Resolver drive signal incorrect”
Explanation: There is a problem with the resolver assembly.
Remedy: Check to make sure that the Master/Slave jumper, JP101, on the
SmartPAC 2 board (see Figure 2-7, page 2-13) is set to the following
position:
• MASTER for a SmartPAC 2 without WPC Clutch/Brake control
integration
• SLAVE for a SmartPAC 2 with WPC Clutch/Brake control integration
• If a position sensor is being used on your press, do not disable it in Initialization mode to
clear the error message. Otherwise, misalignment between the resolver and crankshaft
will not be detected.
• If you do not have a position sensor, be sure to disable the position sensor in
Initialization mode and make no connections to pin #246 on TB107.
