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® photo eyes or 2-wire monitored edge.

Output Definitions / Ratings: Impending operation warning – Relay contacts to close 2 to 10 seconds before 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 countdown will restart when this input is removed. (This is a class 2 circuit)

• To start a timer hold, Connect this input to the 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 the 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 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.
