Setting Timer to Close Function
The Timer-to-Close feature provides the ability to automatically
close the door, after a fixed time delay, after the door has been
moved to its OPEN limit. This time delay is user adjustable by the
on-board Timer-to-Close rotary switch as follows:
To configure the Timer-to-Close feature:
1) Set the rotary switch to the desired time delay setting in the
chart shown above.
• When set to 0, the timer-to-close feature is disabled and the
Timer-to-Close LED is turned off.
• When a non-zero time delay is selected, the Timer-to-Close
LED turns on solid.
• If the operator is configured for constant-contact closing, the
Timer-to-Close feature is disabled and the LED is turned off,
regardless of the rotary switch setting.
• Any action that moves door toward upper limit activates Tim-
er-to-Close cycle and the Timer-to-Close LED will start flash-
ing. Selected countdown time will start when unit reaches
up limit.
• If the door is stopped during its upward travel, the Timer-to-
Close cycle is aborted and the LED will turn on solid.
• If safety is activated during time out cycle, timer will hold until
safety is cleared.
• If the safety edge becomes active at any point during the down-
ward travel, the operator will reverse direction and run the door
to its OPEN limit. This will re-start the Timer-to-Close cycle.
• The Timer-to-Close feature will make three attempts to move the
door to its CLOSE limit. If it is unable to do so, the Timer-to-Close
cycle is terminated and the LED is turned on solid. To re-initiate
timer, door must be cycled closed first.
• 3- strikes on/off feature. Move switch 5 to ON to disable 3 strikes
feature.
• The Timer-to-Close cycle may be user-terminated at any time by
pressing the CLOSE or STOP buttons. The operator will respond
to the input, and the Timer-to-Close LED will turn on solid to
indicate the cycle has ended.
• If OPEN button is pressed, door will open and reset Timer-to
Close.
