ACCESSORY AND RELAY CONNECTIONS
These terminals will provide battery backed power to 24 Vdc
devices and are located at the bottom of the electronic control
board at J4 terminals 1 and 2. Terminal 1 is 24 Vdc (+) and
number 2 is 0 Vdc (-). Peripheral CLASS 2 low voltage devices
that require 24 Vdc power maybe connected here (500 ma.
maximum). EXAMPLE: Vehicle detector, radio receiver.
RELAY OUTPUT K1 - (OPTION)
S1-6 off S1-8 off, relay will fire (latch) when gate is not closed.
S1-6 on S1-8 off, relay will fire when arm is pushed up off of
limit switch (use with slip clutch option) and fires relay when a
tail-gate is detected by the close loop - ANTI TAIL-GATE
ALARM.
S1-6 off S1-8 on, relay will pulse relay when arm reaches full
open position.
S1-6 on S1-8 on, relay will only pulse when input is given to J5
1,2,3 inputs. (see page 10).
BATTERY INSTALLATION
HOOKING UP BATTERY LEADS - ALWAYS HOOKUP AND TURN
ON AC POWER BEFORE INSTALLING BATTERIES. After turning
on AC power, install two new, fully charged 12 volt DC batteries
on shelf next to motor. Connect red lead from operator to the
positive (RED +) terminal of one battery and black lead from the
operator to the (BLACK -) terminal of the OTHER battery. Place
the supplied jumper between the remaining terminals of each
battery if one is not already in place (Figure 1). (Use LiftMaster
MBAT or 29-NP712 for replacement batteries.) Replace in pairs.
WARNING: Do not run operator without installing the batteries.
MASTER/SECOND WIRING
STEP 1: In a master/second configuration, either unit can be
the master. Choose one unit to be the master and then direct all
control wiring to it (also install vehicle detectors and receivers
in it).
STEP 2: At the MASTER, any input (at J5) with control
(detectors, receivers, keypads, timers, etc.) wires to it must
also be run to the same terminals of the second. Along with
these control wires, both operators MUST share a common
ground connection from chassis to chassis (or from common
to common, i.e., master gate J5 terminal #12 to second gate J5
terminal #12).
EXAMPLE: If only open and close are used at master then three
wires will run between gates (Figure 2).
STEP 3: If it is required that if one gate senses an obstruction,
the other reverses also, then 3 additional wires must be run
between the master J3 and second J3 (Figure 3). These
connections are for transmitting IRD (obstruction signals)
between both units. This will allow the master or second to
inform the other that a closing obstruction has occurred and
for it to reverse and open. SET switches on S2, 1-8 the same
on both gates.

IRD - Obstruction Signal Connections
Terminal 1 of Master must go to terminal 4 of
Second and terminal 1 of Second must go to
terminal 4 of Master. Terminal 2 of Master
must go to terminal 2 of Second.
