The Suspension Probe Single Phase Simplex control panel is used to operate a pump for water, dewatering, and storm water applications. Comes in 120/230VAC, 16-20 FLA Ranges, and a Type 4X (outdoor) enclosure. The control panel includes four (4) 20' single point suspension probes, a hand-off-auto (HOA) switch with pump run indicator, and a drain-fill selector switch. The incoming and pump power must match system voltage with conduit connections (required) per local codes. Refer to included electrical schematic for complete wiring and voltage information.
The control panel is operated by the included suspension probes for reference point, pump stop, and pump start. As the liquid level rises/recedes activating the pump start probe, the pump will start and continue to run until the pump stop probe is deactivated to complete the pump cycle. There is no alarm activation included in this series of control panels, refer to models with a fourth suspension probe used as a liquid level alarm. Use the drain-fill selector switch to easily convert from a pump down (drain) to pump up (fill) application without having to rewire the suspension probes.
Auxiliary contacts can be included to connect to a building automation system (BAS) or SCADA system and phone dialers for remote notification of a pump run event.
