Dual setpoint controller that is easy to program. Controls submersible pumps in lift stations, and is designed to field calibrate the Birdcage Level Sensor.
Standard Features:
This controller is simple and inexpensive. It is so simple that even the least-trained operator can program six standard level setpoints for the control of the pumps -the on/off setpoints for the two pumps and the settings for the two alarms. That's it! Everything else is defaulted to a secure menu, pre-programmed for the customer. Everything is readily available in case you have to change range or decimal placement, suppress the zero, or turn off the alternation, etc.
The flexibility and variety of options in the secure menu will be applauded by engineers, while the operators will never have to learn those programming steps. Nothing could be easier!
Standard Features:
- Control ON-OFF for two pumps
- Front-panel programming
- Analog output for run times.
- Secure menu for all other pre-set values
- 24 VDC power for sensor
- Accepts 4 - 20 mA or 1-5 VDC
- Nonvolatile memory, no batteries
- Alternation of pumps set as default
- Setpoints continuously displayed, along with current level readings
