Common Causes
- Loss of power to control panel
- Stop button pressed on control panel
- Control circuit "broken" by an external device (emergency pull switch, float switch, stop button, etc.)
Environment / Applies To
- Control panels (including the RB-series)
Solution Summary
The control circuit is typically re-enabled by pressing the blue control button on the control panel. The control button may also be available on a secondary panel, like a touch screen assembly (TSA) panel:
The control button is typically illuminated when the control circuit is engaged.
Tip: If the control circuit does not engage when the control button is pressed, a device may be preventing the circuit from engaging. Check all devices that are able to disengage the control circuit (emergency pull switch, float switch, stop button, etc.). Simply exercising (pulling, pushing, etc.) these devices can eliminate an issue where a control circuit cannot be engaged.
Once the control circuit is engaged, the error can be acknowledged and the process resumed.
