Electronic

General

The unit comprises a controller and a photo-cell separated by a lead

length of 300mm in order to facilitate greater mounting flexibility. The

unit is designed to automatically switch lighting loads ON and OFF

depending on the ambient lighting levels. It is designed to be built into

an enclosure and is particularly suited for incorporating within a

bulkhead fitting or road sign.

Installation

The sensor unit, containing the light sensitive photo-cell, is supplied

complete with two neoprene washers and a 20mm plastic nut and is

designed to be mounted through a 20mm diameter hole. It is important

that the photo-cell is mounted in such a way that it is not influenced by

any light, direct or reflected, emitted from the luminaire or fitting it is

controlling. If however after installation, the controlled light is switching

ON and OFF periodically, then light from the fitting is Affecting the

controller and the position of the sensor should be moved.

Connections

Blue - Neutral

No earth connection is required on the unit. However the fitting into

which the unit is incorporated may need an earth and reference to the

manufacturer's instructions should be made.

Testing

To check the correct operation of the photo-cell, cover the sensor lens

for approximately 1 minute, the unit will then switch ON. Remove the

cover and wait for approximately 45 seconds, the unit will then switch

OFF.

WARNING: When the unit is first switched ON, the lamp circuit will be

energised and the lamp holder contacts will be LIVE until

the unit has switched OFF in daylight, approximately 45

seconds later. At ALL times whilst the power is applied,

the sensor will have an a.c. voltage across it which can

be as high as 230 Volts. The sensor connections will at all

times be AT MAINS POTENTIAL RELATIVE TO EARTH.

SWITCH OFF MAINS SUPPLY BEFORE REMOVING

SENSOR OR CONTROLLER. It is important that the

mains supply to the unit is maintained at all times and that

before removing the cover for maintenance or any

change to sensor or controller, the mains supply is

isolated. Insulation testing by a suitable instrument can

be carried out on circuits including photo-cells, but not

continuity tests, as high voltage used may damage the

photo-cell.
