O <br />3 <br />YT <br />WEIGHT <br />G� ty"T!y 2 " <br />` <br />-� tether <br />approximate <br />length <br />activation level <br />FIGURE 4 - Float with cable weight <br />SJE-Rhombus3 Type 122 panels are designed to op- <br />erate with three or four floats for pump sequencing. The <br />standard float functions are common pump stop, lead pump <br />start, lag pump start/alarm (three floats), or separate lag and <br />alarm floats (four floats). <br />Three Float Operation: As the liquid level rises to the <br />stop float and tips it to the ON (closed) position, the panel <br />will remain inactive. As the liquid level tips the lead float, <br />the lead pump will start. If the liquid level tips the lag/alarm <br />float, the lag pump will start and the audio/visual alarm will <br />rtivate. Moth pumps and the alarm will remain active until <br />ie liquid level drops and the lag float is in the OFF (open) <br />osition. At this time the alarm will silence. Both pumps will <br />remain on until the liquid level drops to normal and all three <br />floats are in the CFF (open) position. When both pumps have <br />stopped running, the alternator will switch the lead pump and <br />lag pump operating functions in the next sequence. <br />Four Float Operation: The alarm will activate and re- <br />main on only if the alarm float is tipped to the ON (closed) <br />position. <br />Alarm System (Horn and indicator - standard) <br />When an alarm condition occurs, a red light and a horn will <br />be activated. If the testlnormallsilence switch is moved to the <br />silence position, the horn will be silenced. When the alarm <br />condition is cleared, the alarm system is reset. The alarm <br />system can be tested by moving the test/normallsilence <br />switch to the test position. <br />HOA Switch <br />A hand -off -automatic switch is provided for each pump. In <br />the hand mode, the pump Will turn on unless other safety <br />features are employed. In the automatic mode, the pump <br />will turn on from commands by the float switch(es). <br />Pump n Lights <br />le run light will be ON in either the hand or the autocratic <br />,)de when the pump is called to run. <br />�L:ootrol and ,alarm Fusing <br />The control circuit and alarm circuit are fused separately. <br />3.5 inch (9 cm) <br />tether length <br />FIGURE 5 - Mounting clamp detail <br />Control and Alarm Lights <br />Lights will illuminate when control/alarm power is supplied. <br />l:loat Status Ughts <br />Lights will illuminate when the respective float is in the closed <br />position. <br />Circuit Breaker (optional) <br />The pump circuit has a thermal -magnetic circuit breaker <br />which provides pump disconnect and branch circuit protec- <br />tion. <br />Dry Auxiliary Contacts (standard feature) <br />Normally open - Contacts are open ander normal conditions <br />and closed when alarm condition is present. <br />Normally closed - Contacts are closed under normal condi- <br />tions and open when alarm condition is present. Both types <br />automatically reset once alarm condition is cleared. <br />MOTE: Some options ordered may not be included in this <br />manual. Certain options will require alternative circuitry not <br />including float status and control/alarm indicators. <br />For information regarding the <br />operations of options not listed here, <br />or servicing questions <br />please call a aJE-Rhe mbus`°' <br />customer service technician at <br />(1-800-746-6287) <br />Warranty void if panel is modified. <br />
