USER RELAYS - PROGRAMMING PROCEDURE
User Relays - Programming Procedure
The SmartDC Controller is able to interface with many types of external devices through the use of two
user-programmable output relays. All of the user relay functions identified and described in Table 8 are
accessible in the Installer Menu.
The User Relays will operate
normally to less than 18VDC. The
USER 2 RELAY is rated for DC only
up to 48V and does not have an N.C.
(normally closed) connection.
Use the SmartDC Controller buttons to program the user relays according to the following steps:
1�
Select the relay you wish to use.
2�
Enter the appropriate function using the associated number listed in the table.

Name
Description
1
Close limit output
Creates an interlock signal to another operator’s interlock input, or simply
to indicate that the gate is secure or not. The relay is released when the
fully-closed limit switch is tripped. The relay is energized when the fully-
closed limit is released. (Any open command energizes the relay.)
2
Close limit pulse output
Used in a sequenced system to command a second machine to close.
Generates a brief pulsed output that occurs when the close limit is triggered.
3
Open limit output
Indicates a full-open position. This output becomes active when an open-
limit is triggered and deactivates when the open-limit is released or a
close command is received
.
Use this output for a traffic light.
4
Open limit pulse output
Triggers a sequenced barrier arm gate operator to open. Generates a brief
pulsed-output when the open-limit is triggered. An additional pulse is also
generated with any new open command even when the gate is already
fully-opened.
5
Warn before/during
operate output
Controls an external warning device. This output is active whenever
internal warn before operate buzzer is sounding but the relay output is
constant on
.
Activation timing of this relay is controlled by setting User
Menu for Warn Before Operate [bF].
6
Gate Lock output
Controls external solenoid locks or magnetic locks. In both directions
of travel, this output is activated about 7/10ths of a second before the
operator starts moving the gate and remains active while moving as well
as for a few seconds after stopping
.
