Wiring
PULSER WIRING
An optional pulser (available on the Series 1820R only) is used when external monitoring of the dispensing unit operation is desired. The pulser transmits one electrical signal (pulse) for each predetermined amount of fuel dispensed. Reed 10:1 pulsers operating with DC voltages are used. Pulser wiring must be 18AWG and installed in metal conduit separate from all AC wiring. It cannot share a common junction box, wiring trough or conduit with any AC wiring.
CONDUIT
All wiring to the GASBOY pump must be installed in 1/2" threaded, rigid, metal conduit. Do not use knockout boxes and flexible conduit.
If equipped with a DC pulser, AC power wires must be installed in a separate conduit from the DC pulser and the AC power wires and DC pulser wires must not be run in any sort of common conduit or trough.
All wiring and conduit runs must also conform with the National Electrical Code (NFPA 70) and the Automotive and Marine Service Station Code (NFPA 30A). All wiring and conduit runs must conform to local codes.
The conduit layout drawing on the left is for all Series 70 and 1820 rounded cabinet models. The drawing on the right is for 1820R models. The junction boxes shown below the 1820R are supplied with the pump.
