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
  • Selectable pump alternation when used with two pumps to minimize pump wear. With alternation "On", a seal failure or over-temperature condition will force the non-failed pump to lead status and stop alternation.
  • Alarm light for seal failure when used with a sumersible pump that includes a moisture sensor.
  • Alarm light for overheating when used with a pump that includes a thermostat. Pump is removed from service and can be brought back online manually or automatically when pump has cooled down.
  • Runtime displayed by a front panel button.
  • 24 VDC power for level transmitter
  • 4 - 20 mA or voltage signal
  • Nonvolatile memory, no batteries
  • Test System function that simulates the process input to test programming or to insure the pumps are operating.
  • User-selectable security lock-out of programming and/or setpoints.
The Bulldog BD200 Pump Controller provides versatile level control in a standard 1/4 DIN package.

This controller is versatile, simple, and inexpensive making it the ideal instrument for controlling dual pump lifting stations. Setpoints for ON/OFF and HI/LO alarms are easily set on the front panel. These same buttons also Enable/Disable pump alternation. Selectable time delay up to 60 seconds on power up for pump two prevents both pumps from starting at the same time and a large current draw. Alarms for pump seal failure and motor windings overheating are indicated by lights on the front panel. The dial can also display a runtime clock for each pump. An isolated 4-20 mA retransmission is standard. The front face is rated NEMA-4X for outdoor panel mounting. The BD-200 is also available with RS-232 or RS-485 protocol for connectivity with SCADA systems.
