Electrical Issues
A general set of troubleshooting procedures are provided in the following paragraphs. Use a voltmeter to take
the measurements described in the steps. If at any point in the process, a result different than what’s expected
occurs, stop and identify the problem. Refer to Wiring HySecurity Sensors: Smart Touch on page 131.
AC-Powered Gate Operators
PROBLEM 1: Pushed the OPEN and CLOSE button, but the motor is not running.
1. Verify the incoming voltage and phase at the incoming power terminals matches the voltage and phase on the
nameplate of the motor. They must match!
2. Verify the 24VAC transformer has the proper connection to the incoming power (the black wire is always
connected); White – 115VAC*, Red = 208VAC, Orange = 230VAC, Blue = 480VAC.
3. Verify the primary tap wires match line voltage connected to operator. Measure the line voltage carefully to
distinguish between 208V and 230V branch circuits or between 390V and 460V branch circuits. A label on top
of the transformer identies the various voltage taps. This connection must match the voltage on the operator
nameplate.
NOTE: Primary taps do not exist on battery operators.
4. Verify the 24VAC is present at the Red and Green wires from the control transformer to the Power Supply Board
by measuring the bottom of the power supply board at the -ACC+ connectors.
5. Verify that the main power wires are at least the minimum wire size specied in Wire Sizing and Runs on
page 14. Be certain that the branch circuit wire size versus the distance of the run from the main panel is large
enough to avoid excess voltage drop.
6. Verify 24VDC power is present on the Power Supply Board between the +24VDC terminals above the terminal
strip and any screw connection on the terminal strip.
7. Be sure a 20A circuit (protected with a 20A inverse time breaker) is provided.
8. Check and make sure the operator is electrically grounded per NEC Article 250 and local codes.
9. Verify the 24VDC is present at the +24VDC and common terminals located along the lower edge of the Smart
Touch Controller board. (RADIO OPTIONS, etc.)
10. Verify that the “Heart Beat” LED is blinking green.
11. Verify the display is operational on the LCD and VFD display.
12. With the knowledge that the power is correct and the electric motor runs, check the STC display. If an error, alert
or fault code appears, refer to Table 8: Troubleshooting Codes on page 107 to determine possible resolutions.
Electrical Controls
No routine maintenance is needed for theelectrical system or controls. If the environment is very sandy or
dusty, or has many insects, be certain to seal all holes in the electrical enclosure. Blow the dust out of the
electric panel with compressed air. Use “Smart Touch Controller - Troubleshooting” on page to assess and x
error, alert, and fault codes. If it is necessary to call a distributor for assistance, be sure to have your model and
serial number ready. Other helpful information includes the name of the job, approximate date of installation,
and the service record of the operator.
