“Fault message for red sensors “This N/C sensor is open”
Explanation: A red sensor has actuated (i.e., is open to ground). When this message is displayed,
the angle at which the condition was detected is shown.
Remedy: Check for the press or equipment malfunction that the sensor was supposed to
detect. If no malfunction has occurred, check for a problem with the sensor. Check
for loose or detached wiring at the DSI 2 or controller. Check for a severed wire
from the sensor to the DSI 2 or controller.
Miscellaneous Fault Messages
“The press cycle was interrupted before upper or lower limits were reached”
Explanation: The ram is returning to its Upper Limit without having reached its Lower Limit or
returning to its Lower Limit without having reached its Upper Limit.
Remedy: Check to see whether the upstroke or downstroke was prevented by a light curtain
interruption, the ram hitting something, etc. Verify that the Lower Limit set for
Ram Position (see page
RAM POSITION , page 179) is a little higher than BDC, and
adjust, if necessary. Also verify that the ram Upper Limit is set a little lower than
TDC, and adjust, if necessary.
NOTICE
When the ram position at the top during clockwise movement is not the same as the top position
during counter-clockwise movement, as is often the case in a pendulum motion, make sure to set
the Upper Limit just below the lower of these two “top” positions.
“One of the sensor auto enable counters is greater than 99”
Explanation: Normally, this fault will never occur since SmartPAC PRO Servo does not let you
enter a value greater than 99. However, this message could display if there is an
internal problem with SmartPAC PRO Servo.
Remedy: First press RESET. If the message reappears, contact Wintriss Tech. Support.
“Loss of Communication at Address X”
Explanation: SmartPAC PRO Servo is unable to communicate with the optional module
identified by “X” in the message (see Table 7-1).
Remedy: Check the wiring of the specified module. If you continue to get this error message,
call Wintriss Tech. Support.
