SJE-Rhombus Model 32S 3-Phase Duplex Motor Contactor Control Panel

SJE-Rhombus Model 32S - Three Phase Duplex Pump Control Panel

The Model 32S control panel is designed to alternately control two three phase pumps in industrial and commercial water and sewage systems using the robust DPC-4F Pump Control Four Float Controller for pump sequence, alternation, selection, lag pump delay time and alarm.

If a high water alarm condition occurs, the high water alarm float activates the audible/visual alarm system along with auxiliary contacts for remote alarm. Common applications include lift stations and pump chambers. Models available with intrinsically safe relay for circuit extension into hazardous locations.

INNER DOOR FEATURES

Inner Door Provides a Degree of Safety for Panel Operation

1. Hand/Off/Auto Switches (22mm) for Manual Pump Control (mounted on inner door)
2. Elapsed Time Meters Provide Time Monitoring of Pump Operation (mounted on inner door)
3. Green Pump Run Indicator Lights (22mm) Identify Pump Called to Run Condition (mounted on inner door)
4. Adjustable Seal Fail Module Provides Dual Pump Seal Inputs and Two Red Seal Fail Indicators (mounted on inner door)
5. Inner Door Provides Added Safety for Panel Operation

PANEL COMPONENTS>
1. Enclosure Measures 20"x16"x8" Type 4X Stainless Steel or Type 4X Fiberglass 18"x16"x10" with Mounting Feet (for indoor or outdoor use).
2. Padlockable Latch Provides Added Safety.
3. IEC HP Rated Motor Starters Perform Contactor/Circuit Breaker Function, Up to 32 FLA (requires separate overload modules). Provides Location for Field Wiring of Incoming Power and Pumps.
4. Multi-Tap Transformer (208/230/460 VAC primary) Provides 120VAC Control/ Alarm Voltage Along with Primary and Secondary Fusing.
5. Class 10 Ambient Overload Modules (purchased separately) Provide Overload Short Circuit, Phase Failure-Phase Imbalance and Ground Fault Protection (equipment protection only); Accessible Through Inner Door (two overload modules required, field installation required).
6. DPC-4F Controller Sequences Pumps On and Off in Response to Change in Level Input Provided by the Float Switches. The Controller also Provides Pump Alternation Selection ( Alt, 1-2, 2-1), Lag Pump Delay Time (0-60 seconds), and Provides the High Water Alarm and Float Out-of-Sequence Alarm Conditions. For Float Out of Sequences, the Controller will Reassign Float Designation for Continued Operation, until the Float Condition has Cleared.
7. Terminal Blocks Provides Location for Field Wiring of Floats, Auxiliary Alarm Contact, Seal Fail and Thermal Cutout for Each Pump.
8. Ground Bar Provides Location for Field Wiring Ground Wires Incoming Power and Pumps.
9. Auxiliary Alarm Relay Provides Normally Open Contacts for Activation of Remote Devices During High Water Condition.
10. Red LED Beacon Provides 360 Degree Visual Check of Alarm Condition.
11. Alarm Horn Provides Audio Warning of Alarm Condition 95 decibel rating). (Not Shown)
12. Exterior Test/Silence Button (22mm) Allows Horn and Light to be Tested and Horn to be Silenced in an Alarm Condition. Alarm Automatically Resets Once Alarm condition is Cleared.
INTRINSICALLY SAFE MODELS
13. Intrinsically Safe 4-Channel Module Limits the Amount of Energy to Float Switches Preventing Ignition of Flammable Gases.
