The Simple Panel is designed to provide reliable control of tubular motors for garage doors. However, as with any automated system, occasional issues may arise due to wiring errors, configuration settings, safety device activation, or motor setup.
This troubleshooting guide provides a simple, step-by-step reference to help installers and technicians quickly identify common faults and resolve them safely. If a problem occurs, start by checking the symptoms below and follow the suggested actions.
Find the specific Fault
The Door Does Not Move at All
If the door does not respond to any commands, the issue is usually related to the power supply or the control unit itself.
Possible Causes
No power reaching the panel
Blown fuse
Faulty control unit
What to Check
Confirm the 240V power supply is connected and active.
Check the 5A fuse inside the control unit.
If the panel emits a continuous beep, the control unit may be faulty and should be replaced.
The Door Opens but Will Not Close
In some cases, the door may open normally but refuse to close.
Possible Cause
The system has not yet completed a full opening cycle after being powered on.
What to do
Send an open command and allow the door to reach the fully open limit position. Once this is complete, the control unit will allow closing commands.
Possible Cause
The shutter won’t close if there is a limit issue; if so, the panel will produce two beeps.
What to do
Adjust both sets of limits. If the issue persists, we recommend adjusting the limits with the addition of a test lead.
Possible Cause
Safety edge issue; the panel indicates this by emitting 5 beeps.
What to do
Check the safety edge at both the junction box and panel terminal. Ensure connections are secure, and wiring is in the correct order. If all is correct, inspect the rubber profile for damage or distortion.
The Door Moves in the Wrong Direction
If the door closes when it should open (or vice versa), the motor wiring is reversed.
How to fix
Stop the door movement.
Switch the control unit off.
Swap the brown and black motor wires on terminals 5 and 7.
Switch the power back on and test the operation again.
The Door Reaches the Floor and Reopens
If the door closes fully but immediately reopens, the control system is likely detecting an obstruction.
Possible Cause
Bottom limit switch set too low.
What to do
Adjust the bottom limit switch slightly higher.
Possible Cause
Safety edge triggered due to an uneven floor.
What to do
Set the safety edge exclusion for the final 5 cm of closure.
Remote Controls Are Not Working
If the door does not respond to transmitters, the issue may be related to radio programming or memory capacity.
Possible causes
No transmitters programmed
Radio memory full
What to check
If the control unit emits three beeps at startup, no transmitter has been programmed.
Enter programming mode using the P1 and P2 buttons and store a transmitter.
If you hear four beeps, the radio memory is full, and some transmitters will need to be deleted before new ones can be added.
The Door Stops or Reverses During Closing
If the door stops or reverses during operation, a safety device has likely been triggered.
Possible Causes
Safety edge activated
Photocells misaligned
Safety wiring issue
What to Check
Inspect the rubber safety edge for damage or obstruction.
Check the wiring connections for safety devices.
Emergency Stop Fault
If the control unit emits six beeps and the door will not move, there may be a problem with the emergency stop circuit.
What to Check
Ensure the Emergency STOP push-button is not activated.
Verify that the STOP wiring is correctly connected.
The Motor Stops Before the Door Finishes Moving
If the motor starts but stops before the door completes its travel, it may be due to the limit switch configuration or motor protection.
Possible Causes
Limit switches are not correctly set
Motor overheating
What to do
Reconfigure the limit switches.
Allow the motor to cool down if thermal protection has been triggered.
Check the motor wiring and test the motor independently if necessary.
The Door Exceeds Its Normal Running Time
If the control unit emits eight beeps, the system has detected that the door movement has exceeded its expected operating time.
Solution
Check and reset the limit switches to ensure the door stops correctly at the open and closed positions.
Quick Reference: Sound Signals
The Simple Panel uses beep sequences to indicate faults.
No. Beeps | Meaning | Action |
Continuous beep | Control unit fault | Replace unit |
2 beeps | Motor issue | Check wiring, limits, and motor |
3 beeps | No transmitters programmed | Program a transmitter |
4 beeps | Memory full | Delete unused transmitters |
5 beeps | Safety edge fault | Check the safety edge and photocells |
6 beeps | Emergency STOP fault | Check STOP wiring |
8 beeps | Limit switch error | Reset limits |
9–10 beeps | Relay fault | Replace unit |
If the problem persists after following these steps, the issue may require further electrical diagnostics or component replacement. Get in touch with our technical team at technical@ellard.co.uk, and we can guide you through the next steps.
