PD6100 Strain Gauge, Load Cell, & mV Meter Instruction Manual

Application #2: Pump Alternation Using Relays 3 & 4

1. Relays 1 and 2 are set up for low and high alarm indication.
2. Relays 3 and 4 are set up for pump alternation.

6900 Controls high alarm

7000

900 Controls backup pump

6000

1000 Controls main pump

The following graphics provide a visual representation of a typical pump alternation application with high
and low alarm monitoring.
1. Relay #4 turns the main pump on at 6000

gallons and turns it off at 1000 gallons.

2. With the Pump Alternation feature activated,

the next time the level reaches 6000 gallons,
relay #3 transfers and starts the backup
pump.

3. If the backup pump is not able to keep up,

and the level reaches 7000 gallons, relay #4
transfers and starts the main pump as well.

4. Relay #2 trips the High Level Alarm at 7500

gallons and resets at 6900 gallons.

5. Relay #1 trips the Low Level Alarm at 495

gallons and resets at 750 gallons.
