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-12/24VDC.
Ÿ
IMPORTANT:
You must use the MON-12/24VDC to properly monitor entrapment protection devices. To turn this
voltage on for
initial setup
, press 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 (on next page), 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).

MONITORED ENTRAPMENT PROTECTION
DEVICE CONNECTIONS
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 senses a fault (MON_FAULT LED will turn on), the
operator will only work with a constant pressure actuated switch. Once the obstruction is
cleared, the gate will operate normally.
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 connected and the board
detects a fault (MON_FAULT LED will turn on), the operator will only work with a constant
pressure actuated switch. Once the obstruction is cleared, the gate will operate normally.
