Top Stop And Overrun Setting Faults; Overrun Limit Switch Fault - Honeywell SmartPAC 2 User Manual

SmartPAC 2 with WPC Integration

Top Stop and Overrun Setting Faults

Problem: These errors indicate that the overrun limit switch is on before the Top
Stop timing is off. Remember that the Top Stop Timing (actual internal
dwell) is on for twenty degrees.
Remedy: Check that you have properly set Top Stop angle and installed and set the
Overrun Limit Switch correctly. Review "Install the Overrun Limit Sensor
Magnetic Switch," page 44, "Install Magnet for Overrun Limit Sensor,"
page 116, and "Switches 1 and 2 – Overrun Limit Switch Settings," page
242.

Overrun Limit Switch Fault

Problem: The overrun limit switch (made up of the overrun sensor and magnet)
provides overrun timing to WPC. WPC checks that the overrun limit
switch opens and closes only once per stroke, and compares that with the
other timing signals (such as auto carry-up and top stop). If WPC detects
more than one on/off occurrence, it generates the following error message:
"
NOT ALL OF THE TIMING SIGNALS WERE SEEN IN SEQUENCE
Remedy: Review "Install the Overrun Limit Sensor Magnetic Switch," page 44,
"Install Magnet for Overrun Limit Sensor," page 116, and "Switches 1 and
2 – Overrun Limit Switch Settings," page 242, and see LED map, Figure
B at the end of the manual, as you correct this problem. Check the
overrun limit switch installation to make sure that it opens and closes only
once per stroke. Check that you are using the brass screw provided or
other non-ferrous screw. Other considerations: Make sure that the
overrun limit switch has enough dwell to provide an adequate signal at
high speeds. The larger the diameter of the shaft on which the magnet is
mounted, the shorter the dwell. If this is the problem, the solution is to
mount the magnet on a smaller shaft. Also, ensure that the press is not
encountering undue shock and vibration due to excessive blanking. If you
cannot resolve this problem, contact Wintriss Tech Support.
