o PCE faults out with LED Blinking. How many times is the LED Flashing (before pausing)?
See PCEC Manual Chapter 4:2 Table 16 & 17. Based on the number of LED Flashes, these pages will guide you to a possible
fault explanation and the possible solution.
Below are common issues:
o 3 Flashes: Change two of the incoming phases and verify that the motor is spinning in the correct direction. If the motor does
not turn in the correct direction, change the incoming phases back to their original connections and change dip switch #9 to the
desired Line Rotation sequence setting.
o 4 Flashes: Check for open line (i.e. open fuse). Check for incorrect wiring to load. Verify proper operation of the fault contactor.
Dip Switch 15 is set properly for the motor type. Ensure the PCE overload range falls within the range of the motor FLA. Ensure
IN1/IN2 command input is not intermittent from upstream devices.
o 6 Flashes: The user must check that Dip Switch 15 is set properly and re-check motor all connections from PCE/FC to motor. If
F6 persists, a final ohmmeter check on all three phases (SCRs’) must be performed as noted in Table 16. Damaged SCR(s) occur
due to excessive external currents. The installer must check all electrical devices from the feeder to the motor before installing
another PCEC unit.
o Verify all users Dip Switch settings and compare to Factory Default Settings.
o See PCEC User manual Chapter 3:1 & 3.:2 for each setting
o IMPORTANT: Verify if the motor is a 3-Lead Line Connected or 6-Lead Wye-Delta motor and then ensure that PCE DIP #15 is
either DOWN for 6-Lead motor or UP for 3-Lead.
o User claims the PCE is dead with no LED flashes, how can this be verified?
o With voltage applied to PCE A1/A2 [without voltage applied to A1/A2, nothing will happen]; hold down the Reset button for
approximately 5 seconds. This will engage the Test Mode where the LED will Flash 7 times and will also change the state of
the 97/98 & 13/14 contacts. The 7 Flashes verifies an internal check of the unit. If there are no Flashes then the unit is bad.
o The fault contactor should be engaged when power is applied to A1/A2 and will de-energize in the test mode.
o How does the hydraulic pump motor sound?
o A noisy pump motor usually indicates a motor wiring issue. Check the pump motor wiring and make sure it’s connected per
the manufacturers specifications. Check all terminals for loose connections.
o Completed the checklist above and the PCEC is still not functioning. Call Sprecher+Schuh PCEC factory for additional
help.
