This indicates that the detectors have no power, please recheck all wiring.

The lift door contacts could be faulty, check the door contacts

This indication shows that a TX or RX Diode has failed on one of the detectors. The detectors will continue to operate as normal with exception of a failed diode. Where full detection may not be met It is advised that the TX & RX detectors should be replaced.

Check the installation sheet to confirm correct installation including detector alignment. If this is correct, then there could be something is stuck to the detector which is blocking diodes, or a diode could have failed.

The LEDs (Light Emitting Diodes) in the detectors are not replaceable.

Yes, Panachrome+ detectors can be mounted statically using the external door signalling input on the Panachrome+ Controller to determine when green/red indications are shown (see Panachrome+ controller installation ‘External Signalling’).

Yes, an external signal activation provides the quickest response to indicate door movement.

Failsafe; If a fault occurs i.e. losing mains power, damage to the Panachrome+ Controller, extension cables or detectors, the doors will remain open in a safe position without trapping passenger.

The Panachrome+ Controller will require the correct signal from the door operator either Normally Open (N/O) or Normally Closed (N/C) contacts to allow lift doors to return to an open state.

To check failsafe; disconnect working detectors from the Panachrome+ Controller, the doors will remain open, if doors close then the Panachrome+ is not failsafe.

Yes, Panachrome+ detectors can be mounted statically using the external door signalling input on the Panachrome+ Controller to determine when green/red indications are shown (see Panachrome+ controller installation ‘External Signalling’).
