Explosion-Proof Dual-Pump Alternation in Two Tanks

The ProtEX-MAX can be used as an explosion-proof pump controller when combined with a continuous level
transmitter. Since the PD8-6060 accepts two 4-20 mA inputs (from two different level transmitters) and can be
equipped with four relays, it could be used to control and alternate two pumps in two different tanks as well as provide
the 24 V to power the transmitters. The illustration below shows how the relays control both the main and backup
pumps to maintain the levels in tanks 1 and 2.

Learn how to use the ProVu (ProtEX-MAX) meter as an explosion-proof pump controller.
See how the four relays can be used to alternate two pumps and provide high and low alarms.
