motor 1 (MOT1) and motor 2 (MOT2) outputs
Motor 1 is the one which opens first; motor 2 is the one which closes first. Often Motor
1 is on the left hand side when looking out the driveway. The delay between motor 1 and
motor 2 operation is set by the trimmer marked – DEL +. If the motor direction is reversed,
swap the polarity of the connection wires.
flashing warning lamp output (LAMP)
The outputs are set up for a 2 W flashing lamp, at either 12 or 24 V dc, depending on the
board’s supply voltage. The board supplies power to the lamp, but it is a continuous supply,
so the lamp must have a flashing circuit built in. The output supplies power to the lamp
from 1 second prior to opening, until fully open; and from two seconds prior to closing, until
fully closed. If the board is running only from battery backup, then the lamp will only flash
for the first four seconds of operation.
courtesy lamp (EXT. LAMP) / electric lock (EL. LOCK)
module output
To connect an electric lock or a courtesy lamp, it is necessary to fit an optional expansion
module. Only one module can be fitted. This must be connected with the three wires
arranged as red-grey-black from left to right.
The ELU Electric Lock Unit module can accept a lock rated at up to 12V 15W. When a
lock is fitted, it is recommended to fit the STRIKE jumper over both its pins. This enables
a short delay before opening, to allow the lock to release before the gate leaf moves. The
LCU Lamp Control Unit module can accept a lamp rated at up to 12V 15W.
tx photocell power out (TXF), photocell signal in (PHO)
Photocells should have NC (normally closed) contacts when there is no obstruction. Fit a
jumper wire between the signal input terminal and ground if no photocells are fitted. The
maximum total accessory power load allowed is 150 mA. The combined consumption on
the TXF and VA terminals must not exceed this limit. Photocells are part of this total load.
NOTE 1
If the TEST jumper is fitted, the unit performs a function test on the photocells
before each operation. This adds a 200ms delay before every operation. The transmitting
photocell must be powered from the TXF output. Photocells must have NO (normally open)
contacts when the power is off.
NOTE 2
If the PAU trimmer is set to fully anticlockwise and the photocell beam has been
interrupted, then the gates will close 1 second after the beam is cleared.
NOTE 3
The default behaviour of the gates is to react immediately when the beam is
interrupted. Professional Setup Step 12 allows this to be changed. Gates can be made to
stop in response to an obstruction, and then only react after the obstruction is removed.
accessory power output (VA)
The maximum total accessory power load allowed is 150 mA. Accessories in excess of this
limit must be powered directly from the battery.
NOTE
The transmitting photocell must be powered from the TXF output if the TEST
