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 that must be
completed before the system can be functional. Review the installation instructions below and the
Battery
Connection Diagram . 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!
a. 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 Buss 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 is to happen when the AC line
power fails. 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.
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.
