user relays – ProGraMMinG ProCedure
The Smart Touch Controller is able to interface with many types
of external devices through the use of three user programmable
output relays: two mechanical relays (User Relay 1 and User
Relay 2), and one solid state relay (User 3) which is used most often
for connection to ashing devices.
All of the user relay functions identied and described in the table
below are accessible in the Installer Menu
(R1 x, R2 x, R3 x) selections.
NOTE: A setting of zero disables a User Relay. The User Relays will operate
normally to 18VDC. Below 18VDC, alert notication occurs. On Crash products
User 3 relay is unavailable. It is pre-wired for the LED lights.
Use the STC buttons to program the user relays according to
the following steps:
1. Select the relay you wish to use through the Installer
Menu. See Installer Menu: Table 6 on page 66. For
example:
R1 13
(RELAY LOGIC 1) or R2 15 (RELAY LOGIC 2).
2. Select the appropriate function (1 through 42) by
changing the display to the associated number listed in
the table. Use the Select, Next and Previous buttons to
make your selection. Refer to Menu Mode Navigation
on page 60.

Connection
1 Close limit output Output can be used as an interlock signal to another
operator’s interlock input, or simply to indicate that the gate
is secure. The relay is “off” when the gate is closed. The relay
energizes when the fully-closed limit is released. (Any open
command energizes the relay.)
Relay 1, 2 or 3
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.
Relay 1, 2 or 3
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.
Relay 1, 2 or 3
4 Open limit pulse output Used in a sequenced gate system to command a second
machine to open. Generates a brief pulsed output that
occurs when the open limit is triggered.
Relay 1, 2 or 3
5 Warn before/during operate output Controls an external warning device. This output operates at
the same time as the internal warn before operate buzzer.
Relay 1, 2 or 3
6 Gate Lock output Controls external solenoid 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. Output remains active, for a
few seconds, after stopping.
