What do the Operating Indicators on the control box of the 4600 Series operators signify when they are lite?

Resolution:

Power:  The controller is receiving 120VAC power to control the operator.

Fire Alarm:  There is an active fire alarm activation in the building AND it is wired into terminals 13 and 14 of the controller.  The operator will disregard all activations until the alarm condition is cleared within the building.

Normal/SEQ: There is an closed contact activation, requesting the door to open, and/or, there is a sequential activation between two operators taking place.

H.O. / Alt. Action:  Either the hold open switch (or switch connected into terminal 6) or an alternate action sequence has been activated.  Alternate action is opens the door with an switch activation and the door does not close until a second activation is received.  Terminals for wiring will be Alt. Action is usually 15 and 17.  (The operator can be programmed under MODE to always wait for a second activation to close the door or automatically close door after 10, 20, or 30 minutes.)

Lockout timer: This indicates that the operator is disregarding any messages from the safety scanner to while the door is in its closing cycle. (Otherwise door would never close.)

Safety Clear: Door is ready for operation, no detected obstructions.

Safety Active:  Door is receiving a signal from a safety sensor that it there may be an obstruction in the path of the door.
