Three Phase Duplex SJE-Rhombus® Type 322 Installation Instructions and Operation/Troubleshooting Manual 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. All conduit running from the sump or tank to the control panel must be sealed with conduit sealant to prevent moisture or gases from entering the panel. NEMA 4X enclosures are for indoor or outdoor use, primarily to provide a degree of protection against corrosion, windblown dust and rain, splashing water and hose-directed water. Cable connectors must be liquid-tight in NEMA 4X enclosures. Installation Most Type 322 panels are designed to operate with three or four float systems. The three float system is standard, performing the common pump stop, lead pump start, and lag pump start/high level alarm functions. The four float system utilizes separate floats for each function. NOTE: Options ordered may affect the number of floats and their functions. Please reference the schematic provided with the control panel for proper installation. Warranty void if panel is modified. Call factory with servicing questions: 1-800-RHOMBUS (1-800-746-6287) Installation of Floats CAUTION: If control switch cables are not wired and mounted in the correct order, the pump system will not function properly. WARNING: Turn off all power before installing floats in pump chamber. Failure to do so could result in serious or fatal electrical shock. 1. Use float label kit to identify and label cables on both float and stripped ends (stop, lead, lag, alarm, etc.). See schematic for float options. Manufactured by: 2. Determine your normal operating level, as illustrated in Figures 1 & 2. 3. Mount float switches at appropriate levels as illustrated in Figures 3-5. Be sure that floats have free range of motion without touching each other or other equipment in the basin. If using the mounting clamp; follow steps 4-6. 4. Place the cord into the clamp as shown in Figure 5. 22650 County Highway 6 P.O. Box 1708 Detroit Lakes, Minnesota 56502 USA 1-888-DIAL-SJE (1-888-342-5753) Phone: 218-847-1317 Fax: 218-847-4617 E--mail: customer.service@sjerhombus.com Website: www.sjerhombus.com ©SJE-Rhombus PN1008698C • Rev 11/14 5. Locate the clamp at the desired activation level and secure the clamp to the discharge pipe as shown in Figure 5. NOTE: Do not install cord under hose clamp. 6. Tighten the hose clamp using a screwdriver. Over tightening may result in damage to the plastic clamp. Make sure the float cable is not allowed to touch the excess hose clamp band during operation. NOTE: All hose clamp components are made of 18-8 stainless steel material. See your SJE-Rhombus® supplier for replacements. Installation Instructions Mounting the Control Panel 1. Determine mounting location for panel. If distance exceeds the length of either the float switch cables or the pump power cables, splicing will be required. For outdoor or wet installation, we recommend the use of an SJE-Rhombus® liquid-tight junction box with liquid-tight connectors to make required connections. You must use conduit sealant to prevent moisture or gases from entering the panel. 2. Mount control panel with mounting devices furnished. 3. Determine conduit entrance locations on control panel. NOTE: Be sure the incoming power, voltage, amperage, and phase meet the requirements of the pump motors being installed. If in doubt, see the pump identification plate for electrical requirements. 4. Drill proper size holes for type of connectors being used. NOTE: If using conduit, be sure that it is of adequate size to pull the pump and switch cables through. 5. Attach cable connectors and/or conduit connectors to control panel. 7. Run conduit to junction box. Drill proper size holes for the type of conduit used. Attach connectors to junction box. 8. Identify and label each wire before pulling through conduit into control panel and junction box. Make wire splice connections at junction box. 9. Firmly tighten all fittings on junction box. 10. If a junction box is not required, pull cables through conduit into control panel. 11. Set motor protective switches: a) set the dials to match motor full load amps. b) turn dial on motor protective switch to the ON position. NOTE: Resetting the dial with power applied to the motor protective switch could start the motor. 12. Connect pump wires directly to the motor contactors terminal positions T1, T2, and T3. NOTE: Three-phase motors will run in either direction. Check pump motor before installation for proper rotation. To correct rotation, change pump cable connections on any two terminals T1-T2-T3. FOR INSTALLATION WITHOUT A SPLICE, GO TO STEP 10; FOR INSTALLATION REQUIRING A SPLICE, FOLLOW STEPS 6-9. 13. Connect “power-in” conductors to proper locations: 208/240/480 VAC on the 3 position terminal block. Install tagged factory wire to appropriate transformer primary voltage tap. 6. Determine location for mounting junction box according to state and local code requirements. Mount the junction box to proper support.

The standard float functions are common pump stop, lead pump start, lag pump start/alarm (three floats), or separate lag and alarm floats (four floats). Other float options, such as redundant off, are available. Three Float Operation: As the liquid level passes the stop float and tips it to the ON (closed) position, the panel will remain inactive. As the liquid level tips the lead float, the lead pump will start. If the liquid level tips the lag/alarm float, the lag pump will start and the audio/visual alarm will activate. Both pumps and the alarm will remain active until the liquid level drops and the lag float is in the OFF (open) position. At this time the alarm will silence. Both pumps will remain on until the liquid level drops to normal and all three floats are in the OFF (open) position. When both pumps have stopped running, the alternator will switch the lead pump and lag pump operating functions in the next sequence. Four Float Operation: The alarm will activate and remain on only if the alarm float is tipped to the ON (closed) position. Pump Run Lights Each pump has a run light. The run light will be ON in either the hand or the automatic mode when the pump is called to run. Float Status Lights Lights will illuminate when the respective float is in the closed position. Dry Auxiliary Contacts (optional) Normally open - Contacts are open under normal conditions and closed when alarm condition is present. Normally closed - Contacts are closed under normal conditions and open when alarm condition is present. Both types automatically reset once alarm condition is cleared. Seal Failure Circuit and Indicator Light (optional) When an alarm condition occurs, a red light and a horn will be activated. If the test/normal/silence switch is moved to the silence position, the horn will be silenced. When the alarm condition is cleared, the alarm system is reset. The alarm system can be tested by moving the test/normal/silence switch to the test position. The seal fail circuit has resistance sensitivity and will sense the presence of water in the pump seal chamber. Upon installation, turn the sensitivity dial on the seal fail module to the point where the light turns on, then dial back slowly until the light turns off. If water enters the seal chamber at this point, the seal fail circuit will sense the change in resistance. After a short time delay, the indicator light will turn on. When the condition is cleared, the relay will de-energize and the indicator light will turn off. The seal fail relay has a sensitivity adjustment so that false readings may be tuned out. Control/Alarm Switch Thermal Cutout (optional) Alarm System (Horn and Indicator) Allows the control/alarm power to be turned on or off. HOA Switch A hand-off-automatic switch is provided for each pump. In the hand mode, the pump will turn on unless other safety features are employed. In the automatic mode, the pump will turn on from commands by the float switches. Motor Protective Switch A motor protective switch is supplied for each pump to provide an adjustable overload, branch circuit protection and disconnect. The overload must be set in the field. To set the overload, dial the amp scale to the pump’s full load amp rating (FLA). If the FLA’s are unknown, use a calibrated amp meter to measure the pump amperage draw under loaded conditions. An auxiliary contact is wired in series with the magnetic contactor coil so that on an overload trip, the magnetic contactor will be disabled. In the event of an overload trip, the motor protective switch must be reset by first turning the selector handle counterclockwise to the OFF position and then turning the handle 90o clockwise to the ON position. The thermal cutout is wired in series with the magnetic contactor coil. If the pump’s thermal switch opens on high temperature, the contactor will turn off and stop the pump. When the thermal switch cools and closes, the magnetic contactor will turn on if the pump is called to run. NOTE: Some options ordered may not be included in this manual. For information regarding the operations of options not listed here or servicing questions, please call a SJE-Rhombus customer service technician at 1-800-RHOMBUS (1-800-746-6287) Control/Alarm Light The light will illuminate when the control ON/OFF switch is in the ON position. Warranty void if panel is modified. Troubleshooting 1. Isolate the float by disconnecting one or both of the float leads from the float terminals. 2. Place one ohmmeter lead on one of the float wires, and the other ohmmeter lead on the other float wire. 3. Place the ohmmeter dial to read ohms and place on the R X 1 scale. With the float in the “off” position, the scale should read infinity (high resistance). Replace the float if you do not get this reading. With the float in the ON position, the scale should read nearly zero (very low resistance). Replace the float if you do not get this reading. Alarm Horn Pressing the alarm test/normal/silence switch to the test position or activating the alarm float should turn on the alarm horn. If the horn does not sound, replace with horn of same type. NOTE: Readings may vary depending on the length of wire and accuracy of the measuring device. Alarm Light Fuses Pressing the alarm test/normal/silence switch to the test position or activating the alarm float should turn on the alarm light. If the light does not activate, replace with bulb of same type. Check the continuity of the fuse. Pull the fuse out of the fuse block. With the ohmmeter on the R X 1 scale, measure resistance. A reading of infinity indicates a blown fuse and must be replaced. Replace fuse with same type, voltage and amp rating. Alternating Relay or Device The alternation can be sequenced by lifting the float switches or making jumper wires to simulate the floats closing. If the alternator fails during testing, replace with same type. Consult factory at 1-800-RHOMBUS (1-800-746-6287) when in doubt about testing procedures or results. Float Controls Check the floats through their entire range of operation. Clean, adjust, or replace damaged floats. Checking the float resistance - The float resistance can be measured to determine if the float is operating correctly or is defective. Use the following procedure to measure the float resistance: Magnetic Contactor Contacts - Check the contacts for severely burnt or welded contacts. The contactor arm should move freely. Coil - Measure the coil by disconnecting one of the coil leads. Measure the coil resistance by setting the ohmmeter on the R X 1 scale. A defective coil will read zero or infinity, indicating a short or opened coil respectively. If contactor is defective, replace with same type. NOTE: Readings may vary slightly depending on the and accuracy of the measuring device. Motor Protective Switch Test by inserting a paper clip or other small device into the test hole and push to the left. The relay should trip.
