The circuit board’s 24 VDC terminal provides up to 700 mAmps to power accessories such as loop detectors,
keypads, etc. If the total current draw of your accessories exceeds the 700 mAmps, a separate power supply
(transformer) is required.
When installing a safety loop detector or pedestrian switch or a stop switch, make sure to REMOVE the black
jumper between the 24V-COM and SAFETY and/or STOP_CMD terminals.
DO NOT use these terminals for monitored entrapment protection device connection. See next page for wiring.

MON_CLOSE
(LED will indicate when an obstruction is detected or device is not present)
This input is only for the monitored entrapment protection device for the close
direction. When the gate is closing, it will open to the full open position if an
obstruction is sensed and resets the automatic close timer. This input does nothing
in the opening direction. If a device is not connected or the board detects a fault
(MON_FAULT LED will turn on), the operator will only work with a constant pressure
actuated switch.
MON_OPEN
(LED will indicate when an obstruction is detected or device is not present)
This input is only for the monitored entrapment protection device for the open
direction. When the gate is opening, it will reverse for 2 seconds and stop if it senses
an obstruction. This input does nothing in the closing direction. If a device is not
connected or the board detects a fault (MON_FAULT LED will turn on), the operator
will only work with a constant pressure actuated switch.
MONITORED ENTRAPMENT PROTECTION
DEVICE CONNECTION
Ÿ
There are 2 types of sensors that can be connected to the gate operator for UL 325 monitored entrapment
compliance: non-contact sensors (photo eye) and contact sensors (edge sensors).
Ÿ
Monitored entrapment protection devices use 4 wires to connect to the board. From the device, connect the
RELAY
COMMON
to the board
COMMON
and the
NORMALLY CLOSED
relay contact to the assigned
MON_OPEN
or
MON_CLOSE
input. Connect the power wires to the
COMMON
and
MON-24VDC.
Ÿ
IMPORTANT:
You must use the MON-24VDC to properly monitor entrapment protection devices. To turn this voltage
on for
initial setup
, press the reset button on the board. Do not use the 24 VDC terminal on the board’s terminal strip.
Ÿ
NOTE:
The power to the
MON-12/24VDC
terminal will be off when the gate is at rest (not moving). It will be normal to
see the
MON_OPEN
and
MON_CLOSE
LEDs when the gate is closed. If the auto close timer is
OFF
it will do the
same when the gate is at rest in the open position. Also, if no devices are connected both of these lights will stay ON.
Ÿ
Please refer to the device manufacturer wiring instructions for details, making sure to follow the normally closed wiring
directions. Some devices may work on monitoring interfaces other than normally closed.
Ÿ
Should there be a need for more than 1 entrapment protection device for each direction, use a multi-input module from
Miller Edge (model: MIM-62).
