(NB: thermistors shall have a negative temperature coefficient.) 3.3. The gantry control unit shall be suitable for both 2-wire and 5-wire vehicle systems. 3.4. The vehicle shall be bonded to the gantry via the common return wire of the overfill sensors, which shall be connected to pin 10 on the male connector via the vehicle chassis. Pin 10 on the female connector shall connected to the control-unit enclosure which shall connected to the gantry earth. 3.5. All approved bottom-loading vehicles shall carry an identification plate (see 2.3) which specifies the type of overfill-detection sensors installed (i.e. 2-wire or 5wire). 4. Location of the connections 4.1. The design of the liquid-loading and vapour collection facilities on the loading gantry shall be based on the following vehicle-connection envelope. 4.1.1. The height of the centre line of the liquid adapters shall be: maximum 1.4 metres (unladen); minimum 0.5 metre (laden), the preferred height being 0.7 to 1.0 metres). 4.1.2. The horizontal spacing of the adapters shall be not less than 0.25 metres (preferred minimum spacing is 0.3 metres). 4.1.3. All liquid adapters shall be located within an envelope not exceeding 2.5 metres in length. 4.1.4. The vapour-collection adapter should be located preferably to the right of the liquid adapters and at a height not exceeding 1.5 metres (unladen) and not less CONTROL OF VOLATILE ORGANIC COMPOUND-VOC EMISSIONS (STORAGE AND DISTRIBUTION OF PETROL FROM TERMINALS TO SERVICE STATIONS) [ S.L.549.52 17 than 0.5 metres (laden). 4.2. The earth/overfill connector shall be located to the right of the liquid and vapour-collection adapters and at a height not exceeding 1.5 metres (unladen) and not less than 0.5 metre (laden). 4.3. The above connections shall be located on one side of the vehicle only. 5. Safety interlocks 5.1. Earth/Overfill detection Loading shall not be permitted unless a permissive signal is provided by the combined earth/overfill control unit. In the event of an overfill condition or a loss of vehicle earth, the control unit on the gantry shall close the gantry-loading control valve. 5.2. Vapour-collection detection Loading shall not be permitted unless the vapour -collection hose has been connected to the vehicle and there is a free passage for the displaced vapours to flow from the vehicle into the plant vapour-collection system.
