ElECTRICAL SHOCK HAZARD

Disconnect all Power Sources before servicing , failure to do could result in serious injury or death.

This control panel must be installed and serviced by a licensed electrician in accordance with the National Electric Code NFPA-70, state and local electrical codes. UL Type 4X enclosures are for indoor or outdoor use.

For information regarding operation, available options, or servicing questions, please call SJE Rhombus Technical Support.| SJE Rhombus offers a five-year limited warranty on the control panel
and the C-Level™ sensor.

Products returned must be cleaned, sanitized, or decontaminated as necessary prior to shipment to ensure that employees will not be exposed to health hazards in handling said material. All applicable laws and regulations shall apply

Installing the C-Level™ Sensor & Float Switches

The IFS control panel operates with a C-Level™ sensor and 1 or 2 recommended float switches or with 3 to 4 float switches. For C-Level™ sensor operation, C-Level™ sensor operates the Pump Start, Stop and Alarm functions and the back-up float switches are for redundant off and high level alarm. For float switch operation, the float switches operate the Pump Start, Stop and Alarm functions.

Ensure all supply power to the control panel is turned OFF before installing or servicing the C-Level™ sensor, float switches or pumps in the tank. Failure to do so could result in serious or fatal shock.

**NOTE **Do not splice the C-Level™ sensor cable.
Do not run C-Level™ sensor cable or float switch cables in the same conduit as the pump cables

Wiring the Control Panel

Locate conduit entrance at the bottom of the enclosure as shown. Check local codes for the number of power circuits required. The schematic is located on the inside cover of the control panel.
CAUTION! Be sure the incoming voltage is the same as the pump motor nameplate.
Providing separate pump and control/alarm power sources is recommended.
Type 4X conduit must be used to maintain a Type 4X rating of the control panel.
Connect the following wires to the proper terminals:
● incoming power for each pump circuit breaker
● incoming power for control/alarm
● pump 1
● pump 2 (duplex only)
● C-Level™ sensor
● Float switches (recommended)
See schematic label on inside cover of the control panel for details.
Verify correct operation of control panel after installation is complete.

Alarm System (Indicator Light and Horn)
When an alarm condition occurs, the red light and horn will be activated.
If the TEST/SILENCE button is pressed and released, the horn will be silenced. When the alarm condition is cleared, the alarm system is reset.
Circuit Breakers
Each pump circuit has a thermal-magnetic circuit breaker that provides branch circuit protection and a means to disconnect the pump.
Float Test Switches
Push to simulate a float closure condition for each input.
Dry Auxiliary Contacts
Normally Open – Contacts are OPEN under normal conditions and CLOSED when alarm condition is present. CLOSED during power loss.
Automatically resets once alarm condition is cleared. Aux contact rating: 120V, 5A
