1) Adjust Latch and/or Sweep valves on closer clockwise OR
2) Decrease Closing Speed on controller (see page 13)
Door closing too slow
1) Adjust Latch and/or Sweep valves on closer counterclockwise OR
2) Increase Closing Speed on controller (see page 13)
Door does not open to desired location
1) Repeat Home process (see page 14), OR
2) Increase Obst Delay, OR
3) Adjust Backcheck valve on closer counterclockwise, OR
4) Decrease spring force on closer body (door must still close in event of power failure (see page 13), OR
5) Ensure shoe is properly oriented on door (see page 12)
Door does not reach fully opened position
1) Repeat Home process (see page 14), OR
2) Increase Obst Delay, OR
3) Adjust Backcheck valve on closer counterclockwise, OR

Door opens and closes repeatedly
Change selector mode switch from H/O to On
Motor is driving in the wrong direction
Change Mount (Push / Pull) on controller, reset Home process (see page 17), and save values
When door reaches open position,
door drifts toward closed position
Increase Hold Speed on controller (see pages 14 and 18) until door stops drifting
When door reaches open position,
door drifts further open
Decrease Hold Speed on controller (see pages 14 and 18) until door stops drifting
When door reaches open position, door bounces
Decrease Slow Speed on controller (see pages 14 and 18)
When signal is received, operator tries to open
door before auxiliary components are unlatched /
retracted
1) Confirm latch devices are getting proper power,
2) Confirm latch devices are receiving power long enough to fully retract - adjust Latch Retraction on
controller (see pages 14 and 18) as needed,
3) If latch device is not retracting fast enough, increase Start Delay on controller (see pages 14 and 18) to
assure latch device has had sufficient time to fully retract before operator starts opening door.
Error message says “Short Circuit”
Turn off power to unit . Check wiring for short / cut .
Error message says “Over Voltage”
Check incoming power - line voltage has exceeded 145VAC
Error message says “Under Voltage”
Check incoming power - line voltage has dropped below 80VAC
Error message says “Aux1, Aux 2, or Aux 3 Stuck”
Disconnect Aux 1, 2, or 3 inputs and confirm error message goes away. If so, make sure input device is not
stuck (sending constant signal) . Controller has a 3 minute protection limit .
Error message says “Comm Error”
Inverter must be replaced
Error message says “Presence Detect”
Unit has a presence detector attached and device has been activated
Error message says “Drive Disabled”
Selector mode switch is in the “Off” position

Cover extrusion has been stretched too wide and will not properly secure
When doors are closing Follower door hits astragal
on Master door and will not fully close
1) Confirm door with astragal is set to Master-Coordinator
2) Adjust ‘Master Stop’ value to move position where Master door will ‘stop’ and wait for Follower door to
fully close . Once Follower door has fully closed, Master door should then close .
