A few typical problems and their associated troubleshooting procedures are provided to facilitate identification
and resolution.
PROBLEM 1:
Pressing the Open and Close buttons produce no response (nothing happens).
1.
Verify the line voltage is present and matches the operator’s input voltage requi 10%.
2.
Verify the control voltage is present at the Power Supply Common and 24VDC terminals. It may be necessary to
reset the circuit breaker (black button) on the transformer.
3.
If an external Stop button is not used, verify a jumper wire connects Common to Stop.
4.
Verify there are no Faults or Errors being reported on the LCD display.
5.
Jump COM to the OPEN or CLOSE INPUT and verify that the LED lights on the STC board which indicates that
the input is active and working properly. To help in diagnosing the problem, take note of what other inputs light
up and check the display for codes.
6.
Verify there are no active safety device inputs.
PROBLEM 2:
Hydraulic pump is running and the hydraulic pressure is between 0 - 1200 PSI, but the gate is not moving.
The Smart Touch Controller reports system malfunctions on its LCD display and the buzzer will emit a series of chirps
at defined intervals. Review the table of Alerts, Faults and Errors listed in
To check the status of all inputs on the terminal strip, the LED tact button must be pushed.
If the power is three-phase, verify counter-clockwise electric motor rotation. To reverse rotational direction, switch any
two AC lines.
NOTE:
The VFD Motor Controller displays trip and fault codes. Check to see if any error codes appear on the VFD
display. Most VFD issues are resolved through the STC software and modbus interface.
1.
Check the hydraulic fluid level by removing the plug in the pump reservoir. If necessary, add fluid at this location
until the level is about ½ inch below the filler hole.
2.
Unplug the hydraulic hoses and run the pump; if the pressure is low, adjust the Pressure Relief Valve.
3.
If the Pressure Gauge does not respond to adjustment of the Pressure Relief Valve, you may need to completely
remove the valve, depress the plunger at the nose end with a blunt tool (e.g., a hex key) and blow on it to
remove any debris. Contact HySecurity Technical Support first (see page 2) before performing this procedure.
PROBLEM 3:
The gate only opens or only closes.
1.
Verify that no external device is commanding the gate to open or close by watching the LEDs associated with
each input.
2.
If the gate only opens, the Open Valve is probably stuck and needs to be checked for debris and cleared.
3.
If the gate only closes, the Solenoid Coil may not be energizing or it may be defective.
4.
Carefully, replace the valve.
PROBLEM 4:
A run command causes PEC to appear on display.
1.
Check that the photo eye is not blocked. If it is, remove the blockage and realign the photo eye. Refer to
on page 88.
2.
If you have a battery-powered photo eye, check that the batteries are viable and fresh.
3.
If needed, realign the photo eye.
