18 - ACCESSORY INPUTS AND OUTPUTS
GATE OPERATOR ACCESSORY INPUTS:
Auxiliary Inputs 1 (16) and 2 (18):
These digital inputs may be connected
to the digital outputs of accessories and programmed to activate or control
the gate operator in a number of different modes. Shorting the pins through a
dry contact activates the programmed settings for these inputs. These inputs
are programmed in the “FUNCTION Auxiliary I/O” menu.
SAFETY LOOP Input:
(22) Dry contact input that can be programmed for an
inductive safety loop or photo-eye detector. Shorting pin 22 to GND reverses
a closing gate to the full open position. The opened gate is held opened for
as long as the LOOP input is active.
SHADOW (LOOP 1) Input:
(24) Dry contact input that can be programmed
for an inductive safety loop or photo-eye detector. Shorting the LOOP 1 input
(24) to GND maintains an OPEN gate fully open and a CLOSED gate fully
closed until deactivated.
Setting the LOOP1 input to “Photo Mode” causes the moving gate to stop,
then reopens the gate when the LOOP1 input is deactivated.
ENTRAPMENT (LOOP 2) Input:
(26) Dry contact input that can be
programmed for an inductive safety loop or photo-eye detector. Shorting the
LOOP2 input (26) to GND while the gate is opening cause the gate to close
to the fully closed position. This loop input is intended for use with safety
sensors to prevent entrapment between the opening gate and an adjacent
wall or structure.
Edge Input:
(28) This input may be configured as “DIGITAL” or “ANALOG”
as required by the sensor type. When configured as “DIGITAL”, this is a dry
contact input; otherwise when configured as “ANALOG”, the input must
measure 8200ohms. When the input is activated it stops the gate regardless
of direction of travel, momentarily reverses it then stops.
Exit Input:
(30) Dry contact input for a vehicle exit sensor. Shorting this
input to GND opens gate from the closed position and holds gate open with
maintained input or reverses gate if closing.
Fire Input:
(32) Dry contact input for a fire department control switch. Opens
the gate and holds the gate open until the control switch is deactivated. This
input is “hold to run”. Auto-close is disabled when this input is activated. Also
clears hard shutdown.
GUARD STATION
Guard Station Open:
(34) Dry contact input for a guard station open switch.
Momentarily shorting the digital input to GND opens the gate to the full open
position with the subsequent auto-close feature enabled.
Guard Station Stop:
(35) Dry contact input (Normally Closed) for a guard
station stop switch. Momentarily opening this input stops the opening gate at
its current position. While this input is activated, all other inputs are disabled
and are not functional.
Guard Station Close:
(36) Dry contact input for a guard station close
switch. Momentarily shorting the digital input to GND closes the gate (master
and slave).
RADIO
Radio Open:
(39) Dry contact input for an accessory radio open switch.
Momentarily shorting the digital input to GND opens the gate to the full open
position with the subsequent auto-close feature enabled.
Radio Close:
(40) Dry contact input for an accessory radio close switch.
Momentarily shorting the digital input to GND closes the gate.
Radio Input:
Open/Close: (39 and 40) If you tie open and close together the
unit will operate as a Step by Step command each time the input is shorted
to GND, it will either OPEN, STOP or CLOSE.

Figure - BOARD OUTPUTS
GATE OPERATOR ACCESSORY OUTPUTS:
OUT1 and OUT2:
Individual, isolated relays provide COMMON, NORMALLY
OPEN, and NORMALLY CLOSED dry contacts for switching accessories
based on programming of the “Auxiliary IO” function. These outputs are
programmed in the “FUNCTION Auxiliary I/O” menu.
Magnetic Lock:
Provides fused power (1.85A max) and isolated relay
COMMON, NORMALLY OPEN, and NORMALLY CLOSED dry contacts for
electrically powered and maintained magnetic locks. The output time for
magnetic lock activation/deactivation may be adjusted from 0 to 5 seconds.
Lamp:
Provides fused power (1.85A max) to drive a flashing warning lamp
to indicate gate operation. This output is active when the gate is operating
(Opening and Closing). Lamp Delay sets the amount of time the lamp
accessory output is activated prior to gate movement. Settings from 0 to 5
seconds with a step of 0.5 seconds.
Alarm:
Provides fused power (0.5A @ 12VDC) to drive an alarm siren
to signal the occurrence of a hard shutdown, caused by 2 consecutive
entrapment events (signals). This alarm output is reset by pressing the “Reset
Hard Shutdown” button on the front panel or activating the “FIRE” input.
