Three Phase Duplex Alternating Pump Control with Intrinsically Safe Circuits
The Model 324 Build-A-Panel™ control panel provides greater flexibility by ordering through options, allowing you to customize a standard panel to your specific needs.
The Model 324 control panel provides a reliable means of controlling two alternating 208/240/480V three phase pumps in applications requiring intrinsically safe float circuits or other circuit extensions.
The alternating action equalizes pump wear. In addition, this system provides override control should either pump fail. If an alarm condition occurs, an additional alarm switch activates the audio/visual alarm system.
Common applications include pump chambers, lift stations or other installations classified as hazardous locations requiring intrinsically safe circuits.
- NEMA 4X (indoor/outdoor) enclosure
- Red alarm beacon provides 360o visual check of alarm condition
- Alarm horn provides audio warning of alarm condition
- Exterior alarm test/normal/silence switch allow horn and light to be tested and horn to be silenced in an alarm condition; alarm automatically resets once alarm condition is cleared
- Horn silence relay
- Intrinsically safe module limits the amount of energy to switches preventing ignition of flammable gases
- Intrinsically safe partition isolates intrinsically safe wiring
- Motor protective switches provide adjustable overload, branch circuit protection and pump disconnect
- IEC motor contactors control pumps by switching electrical lines
- Hand/Off/Auto (HOA) switches for manual pump control
- Multi-tap transformer (208/240/480 VAC primary) provides 120V control/alarm voltage
- Alternating circuit board (U.S. patent # 5,909,532) provides pump control and alternation
- Green pump run indicator light
- Control on/off switch
- Alarm and control fuses/indicators
- Input power terminal block
- Ground lugs
