- Duplex Pump Down sensor stick with set points for Pump 1 On, Pump 2 On, All Pumps Off and High Alarm with a Common Relay Wire Input.
- The 3SPD24R-STK Checkpoint SmartProbe sensor stick is used in dirty water applications. The sensor stick provides a Duplex Pump Down function and High Alarm with a common relay contact input and independent switch outputs. The VDC applied to the common relay contact will be applied to the switch output when that switch is active.
- Programming logic provides a sequence on and all off function for Pumps 1 and 2. Each pump will turn on when water contacts its respective sensor ring and both pumps will turn off when water is below the All Pumps Off sensor ring.
- The sensor uses a differential between the Pump 1 On and All Pumps Off to determine when the Pump 1 is needed and a similar differential between Pump 2 On and All Pumps Off. This hysteresis allows for the control over On and Off functions using a single switch output for each pump.
