Wiring and Control Configuration for DC Operators
If this installation is a 24-Volt DC battery type gate operator, there are a few additional steps to complete before the
system can be functional. Review the installation instructions, step #10 on page Error! Bookmark not defined. and the
connection diagram on
page 58 (2-battery system).
Be certain the DC power disconnect switch is turned off before making any connections.
1. Connect the heavy gauge wires between the battery enclosure and the gate operator as follows: Be certain to
observe polarity carefully!
From the battery enclosure the (+) lead connects to the lug on the large rotary power disconnect switch. The
(-) lead connects to the lug on the circuit breaker. At the gate operator the (+) lead connects directly to the
lug on the top of the DC electric motor. The (-) lead connects to the bottom lug on the contactor mounted
alongside the DC motor. All lug connections must be tightened very securely since they pass high current to
the gate operator.
2. Connect two separate 14-gauge circuits between the battery enclosure and the gate operator. One circuit
provides the 24 VDC to the gate operator controls and the second circuit is required so that the Smart Touch
Controller knows that the battery charger is operating normally on AC power. Be certain to observe polarity
carefully!
a. Connect four wires to the terminal strip in the battery supply labeled: (+)24, (-)24, COM, #21. The 24 Volt
(+) and (-) terminals connect to the red (+) and black (-) wires at the on/off power switch in the gate
operator.
b. The COM and #21 terminals connect to the Common Bus and to terminal #21 (Charger AC power loss)
on the Smart Touch Controller.
3. The Smart Touch Controller User Menu (U4) provides four optional system configurations for 24-Volt DC battery
type gate operators. Since this is an uninterruptible power supply system, the installer must decide, depending
upon customer preference, what happens upon AC line power failure. The User Relays will operate to less than
18VDC. There are four functional choices provided in the User Menu, item [AP_].
Setting 0 (Type A): The operator functions normally until the batteries drop to 20 Volts, then auto open and lock
until the battery voltage recovers to 23.5 Volts. The gate can still be manually closed only by a Close Pushbutton
or an Emergency Close input and will then re-open by any open command until the battery voltage drops to 17
Volts at which time the gate is absolutely locked open, unless moved manually.
Setting 1 (Type B): The operator functions normally until the batteries drop to 20 Volts, then auto close and lock
closed until battery voltage recovers to 23.5 Volts. The gate can only be opened by a special combination of a
Stop Pushbutton input, then within 1 second, an Open Pushbutton input. The Fire Department open input can
open the gate without the special PBS enabling pre-input. The gate can be re-closed only by Close Pushbutton
and the Emergency Close inputs. When the battery voltage drops to 17 Volts, the gate completes its final cycle
and stays in the full open or full closed position, depending upon which cycle was last.
Setting 2 (Type C): The operator automatically opens five seconds after loss of AC power and locks open, until
AC power is restored. The gate can still be manually closed only by a Close Pushbutton or an Emergency Close
input and will then re-open by any open command until the battery voltage drops to 17 Volts at which time the
gate is absolutely locked open.
Setting 3 (Type D): Same as type C, except the operator initially does nothing after loss of AC power, but then
locks open after the next open command of any type.
