Photo Electric Control Cell
- Photo electric control cells shall comply with the requirements of BS 5972 and offer a Class II protection from electric shock as defined in BS EN 60598.
- Unit must be completely weatherproof, hermetically sealed against the ingress of moisture. It shall be resistant to vibration or change in temperature. It shall be housed in a strong impact resistant low profile translucent housing, the surface of which shall be non- oxidizing and impervious to deterioration.
- The photo electric control unit (PECU) shall be guaranteed for a period of not less than six years, failures within that period of time to be replaced free of charge.
- They will be capable of working in an ambient temperature of up to + 60°C.
- The operation level should be preset to ON 70/100 Lux the ratio of ON to OFF should be approximately 1:2. There shall be no means of manual adjustment to the PECU’s calibration and it shall not need to be orientated to operate as required.
- An override facility shall be provided for maintenance.
- There should be a minimum 15 second delay to prevent the unit from functioning due to short period high illumination such as lightning etc.
- The power supply to the PECU shall be 230V 60Hz. A.C with a contact output rating of 30A at 230V (resistive).
- The PECU and associated relay or switching device shall have pre matched responses and housed in the same envelope. The contact rating shall be 1500-Watts (1800 V.A) and should be fitted with a snap action to prevent chatter. In the case of the load to be switched then the PECU can switch directly, a contactor shall be used.
- The photocell shall be located within the road lighting feeder pillar or pole mounted at a height of (3) three meters -or as directed by the Engineer- such that it can be easily removed. It shall be housed within a small compartment with an acrylic fascia plate set into the surface of the feeder pillar for the satisfactory operation of the photocell. The control circuitry for the correct switching of the road lighting will be housed within the adjacent feeder pillar. The associated specification requirements will be dealt with within that section of the specification.
