PETROVEND SYSTEM 2 CONTROLLER
LVDIM is connected to the PV270 pump relay board (in the System 2 controller) and thence to the pulsers (see
Figure 29).
PetroVend 4-conductor shielded cable (part no. 12-1026) must be used to connect to pulsers; or you must run
#18 AWG gas, oil, and fire-resistant wire in metal conduit (separate from high-voltage wiring) to the pulsers.
