  If your DITEC Control System automation isn't opening or closing, start by checking the power supply cable. If that's not the issue, it could be short-circuited accessories. Disconnect all accessories from terminals 0-30 (ensuring a 24V= voltage is present), then reconnect them one at a time. Also, check if the line fuse is blown and replace it if needed. Verify that the safety contacts are correctly closed (NC) and properly connected to terminals 6-8 on the control panel, including the self-controlled safety edge. Ensure photocells are clean and functioning. If the automatic closure isn't working, try issuing any command. If problems persist after these checks, there may be a motor fault, check the motor connection.

  If your DITEC Control Systems remote control has a limited range or doesn't work when the automation is moving, the radio transmission might be blocked by metal structures or reinforced concrete walls. Try installing the antenna outside. Also, consider replacing the transmitter batteries.

  If the external safety devices on your DITEC Control Systems aren't activating, it could be due to incorrect connections between the photocells and the control panel. Verify that / is displayed. Connect NC safety contacts together in series and remove any jumpers on the control panel terminal board. Also, check the ? and ? setting.

  If your DITEC Control Systems automation opens or closes briefly and then stops, there might be friction present. Manually check that the automation moves freely and check the / adjustment. Make sure that any limit switches, if present, are working correctly.

  If the DITEC Control Systems remote control isn't working, the issue could be due to no storage module or an incorrect one. Switch the automation off and plug in the correct storage module. Also, check the correct memorisation of the transmitters on the built-in radio. If there is a fault with the radio receiver that is built into the control panel, the remote control codes can be read by removing the storage module.
