SMART DC CONTROLLER
USER RELAYS - PROGRAMMING PROCEDURE
The Smart DC 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 identied and described in Table 13
are accessible in the Installer Menu.
Use the Smart DC Controller buttons to program the user relays according to the following steps:
1. Select and connect to the relay you wish to use on the Smart DC Controller board.
2. Access the Installer Menu and RL 1 or RL 2 display (depending on the relay you have connected).
3. Enter the appropriate function using the associated number (1 through 45) listed in the table.
Table 13. User-Programmable User Relays - Function Options
No. Name Description
1 Close limit output
Creates an interlock signal to another operator's interlock input, or
simply to indicate that gate is secure or not. Relay is released when
fully-closed limit switch is tripped. Relay is energized when fully-closed
limit is released. (Any open command energizes 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 close limit is triggered.
3 Open limit output
Indicates gate is at full-open position. Output becomes active when an
open-limit is triggered and deactivates when open-limit is released or
a close command is received. Use this output for a trafc light.
4
Open limit pulse
output
Triggers a sequenced barrier arm gate operator to open. Generates a
brief pulsed-output when open-limit is triggered. An additional pulse is
also generated with any new open command even when 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 operator
starts moving the gate.
7
Gate forced open
output
Activated if gate is forced off closed limit switch and operator is not able
to restore gate to full closed position within four seconds. The buzzer
resets itself in 30 seconds but relay stays active until gate receives a
run command.
NOTICE
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 a N.C. (normally closed) connection.
