Timer-to-Close Module Accessory

garage door operator accessory ​ ​​​​
​​​​​​​​​​​​​Provides an automatic door closing feature that is easily installed and automatically recognized by the operator system. The Timer to Close feature can be selected to start when the door is opened from inputs such as the open button on the wall control, optional radio control input or auxiliary open input via an optional device. The module is installed in the operator electronic box and connects to the main circuit board through an expansion port connector.​

Easily expand the features of your commercial operator with an optional Timer to Close Module board. The Timer to Close Module provides an automatic door closing feature that is easily installed and automatically recognized by the operator system.

The Timer to Close Module is available for the following commercial door operators: RHX®, RSX®, RMX® and CDX®​

Timer To Close Module

​Specifications

Timer

The timer is selectable from 1 second to 5 minutes. It requires the use of one of the following monitored reversing inputs: Safe–T–Beam® photoeyes or 2-wire monitored edge


Output definitions / ratings

Impending operation warning – Relay contacts to close 2 to 10 seconds prior to door closing.

  • 1 set of Single Pole Single Throw (SPST) normally open contacts
  • Rated 3 amps at 120VAC max


Input definitions

Timer Hold –This input causes an active timer to reset and hold. The count down will restart when this input is removed. (This is a class 2 circuit)

  • To start a timer hold: Connect this input to ground (GND) via an optional device.
  • To remove a timer hold: Disconnect this input from ground (GND) via an optional device
  • In addition to the timer hold input, any active reversing device will reset and hold the timer


Auxiliary open input

This input causes a closed or stopped door to open, prevents an open door from closing and reverses a closing door. This input can be selected to initiate the timer. (This is a Class 2 circuit)

  • To start an auxiliary open: Momentarily connect this input to ground (GND) via an optional device.


Normally closed reversing input

This input will reverse a closing door or prevent an open door from closing. This option is selected from a menu on the commercial operator control board.

  • To initiate a normally closed reverse: Momentarily disconnect this input from ground (GND) via a normally closed reversing device.


Monitored edge sensor input

This input will reverse a closing door or prevent an open door from closing. Requires the use of a 2-wire Miller Edge Sensor System designed to work with the commercial operator control board. This option is selected from a menu on the control board

  • To initiate a monitored edge sensor reverse: Momentarily connect this input to ground (GND).

Note: This input will detect broken or short – circuited wiring to the edge sensor and will interpret these as active inputs. (No additional equipment required.)


Power supply requirements

Voltage - nominal 24V DC via the expension port.
User interface – one 12 position and one 2 position terminal block.
Max Wire Size – 12 AWG, min wire size 20AWG – stranded wire.
