Do all units have a high pressure transducer and manual high pressure switch?

All 60 cycle NRL’s are equipped with an AP (HP) transducer which provides an analogue signal to the gr3 controller. The trip point for the AP (HP) transducer can be adjusted from downward from 39 bar (566 PSIG). To suit site conditions. The manual AP (HP) reset control cuts out at 41 bar (595 PSIG) and must be physically reset.
