Single phase, duplex alternating pump control with override.
The Model 122 control panel is designed to alternately control two 120, 208, or 240 VAC single phase pumps in water and sewage
installations. The alternating action equalizes pump wear. In addition to the alternating pump control, this system provides override
control should either pump fail. If an alarm condition occurs, an alarm switch activates the audio/visual alarm system. Common
applications include pump chambers, sump pump basins, irrigation systems and lift stations.
MODEL 122 Control Panel
1. Enclosure measures 10 X 10 X 6 inches (25.4 X 25.4 X 15.24 cm).
Choice of NEMA 1 (steel for indoor use), or NEMA 4X (ultraviolet stabilized
thermoplastic with removable mounting feet for outdoor or indoor use).
Note: Options selected may increase enclosure size and change component
layout.
2. Magnetic Motor Contactors control pumps by switching electrical lines.
3. HOA Switches for manual pump control (mounted on circuit board).
4. Control Circuit Board provides pump control and alternation.
5. Green pump Run Indicator Lights (mounted on circuit board).
6. Circuit Breakers (optional) provide pump disconnect and branch circuit
protection.
7. Ground Lugs
8. Float Status Indicator Lights (mounted on circuit board).
9. Control and Alarm Power Indicator Lights (mounted on circuit board)
10. Auxiliary Alarm Contact, form C (mounted on circuit board).
NOTE: Schematic is located inside the panel on enclosure cover.
STANDARD ALARM PACKAGE
11. Red Alarm Beacon provides 360° visual check of alarm condition.
Note: NEMA 1 style utilizes a door mounted indicator in lieu of a beacon.
12. Alarm Horn provides audio warning of alarm condition (83 to 85 decibel
rating).
Note: NEMA 1 style utilizes an internally mounted buzzer in lieu of horn.
13. Exterior Alarm Test/Normal/Silence Switch allows horn and light to be tested
and horn to be silenced in an alarm condition. Alarm automatically resets once
alarm condition is cleared.
14. Horn Silence Relay (mounted on circuit board).
NOTE: other options available.
