ISSUE:

Stations are not turning on or are stuck on

  • On the Output Station Module (or ROM8), check for corrosion where the ribbon cable plugs into the connector.
  • Look for damage to the power connector wire leading out of the Output Station Module.
  • Check for loose or corroded field wires at the screw-in connectors. Make sure that the connections are tight.
  • Swap the Output Station Module with a known operational unit. If this fixes the problem, the original board should be repaired or replaced with a new one.
  • If the issue persists, check the functionality of the Terminal Board, swapping it with a known operational unit to rule out the Timing Mechanism.
  • Check the large white connectors (where the Timing Mechanism plugs into) for corrosion and damage.
