Optional Wiring
If alternate output functions are required, see Options for User Programmable Output Relays 1-3.
NOTE: User 3 is rated for DC only up to 48VDC and does not have a NC connection.
Connecting an Interlocked Pair:
An interlocked pair of operators is not a Master/Slave system, but is simply two gate operators
interlocked such that the one cannot open unless the other is fully closed. This connection is used
frequently at correctional facilities for Sally Port gates. The Smart Touch Controller provides both an
interlock input (#7) and the interlock output contact that is required.
1. User relay 3 on the Smart Touch Board has been set by the factory to provide the necessary
interlock function. Connect a total of four wires between operator #1 and operator #2 as follows:
One wire to the Common buss of each operator to the User 3 relay COM terminal of the other
operator. Then, connect wires from the User 3 relay NO terminal to the Interlock input (#7) of the
other operator.
2. If User relay 3 has already been used for a different function, then one of the other relays User 1
or User 2 must be wired as described above and set to output function 1. The user relays are
configured in the Installer Menu as item [r1__], [r2__] or [r3__] according to the definitions
described in Options for User Programmable Output Relays 1-3.
3. The interlock input, terminal #7, is convertible to alternately be a time clock input, so it is possible
that it may need to be switched back for the interlock function. If this alteration is needed, go to
the Installer Menu, and set item [tC _] to be [tC_1].
Connecting to an External Lock Mechanism:
An external solenoid lock or maglock can be controlled by the Smart Touch Controller to unlock just
before gate motion begins.
1. User relay 2 has been set by the factory to provide the necessary output for a solenoid lock.
Connect the voltage matching the lock solenoid to User 2 COM and connect a solenoid coil to
User 2 NO (connect a maglock coil to User 2 NC). The un-switched solenoid or maglock wire
connects directly to its supply voltage common conductor.
2. If User relay 2 has already been used for a different function, then one of the other relays User 1
or User 3 must be wired as described above and set to output function 6. The user relays are
configured in the Installer Menu as item [r1__], [r2__] or [r3__] according to the definitions
described in Options for User Programmable Output Relays 1-3.
Connecting the Gate Secure Position Indicator Output:
An external device can be signaled by the Smart Touch Controller to indicate the gate is secure.
1. User relay 1 has been set by the factory to provide the necessary output for position indication.
Connect the voltage matching the indicator light to User 1 COM and connect the gate secure light
to User 1 NC. The other indicator light wire connects directly to the voltage common conductor.
If an unsecured light is required, connect it to User 1 NO.
2. If User relay 1 has already been used for a different function, then one of the other relays User 2
or User 3 must be wired as described above and set to output function 1. The user relays are
configured in the Installer Menu as item [r1__], [r2__] or [r3__] according to the definitions
described in Options for User Programmable Output Relays 1-3.
