The system consists of a single control panel and three easily installed sensor floats. Control Panel Exterior The non-corrosive, indoor and/or outdoor enclosure comes pre-assembled. The panel exterior features a large red alarm beacon and 83 to 85 dB audible alarm horn. Exterior alarm Test/Normal/Silence Switch allows horn and light to be tested or horn to be silenced in an alarm condition. Horn automatically resets once alarm condition is cleared. Control Panel Interior The panel interior consists of a heavy-duty motor contactor and printed circuit board controller. Handy HOA switch allows for either “Hand” (manual), “Off” or “Automatic” pump operation. A control switch turns off power to the float circuitry. The control switch and the HOA switch may be turned off to provide an additional safety feature when servicing. These switches are located inside the panel to protect against activation by unauthorized personnel. A multitap transformer provides 120V control voltage. Motor protective switch provide adjustable overload protection, short circuit protection and pump disconnect. Green “Pump Run” indicator light, alarm fuses, a control fuse and alarm and control power indicators all mounted on circuit board. Easy-to-follow wiring diagram and terminal strip provide for simple installation. 3 Phase Simplex Alarm System & Pump Control Specifications Model No. 3121W151H17A Item No. 513282 Volts 208/240/480 Hertz 60 Phase 3 F.L.A. 2.8 - 4.0 Dimensions H x L x W (in.) 15.5 x 11.4 x 7.3 Weight (lb.) 21 3121W181H17A 513284 208/240/480 60 3121H221H17A 513286 208/240/480 60 3 5.5 - 8.0 15.5 x 11.4 x 7.3 21 3 11.0 - 16.0 15.5 x 11.4 x 7.3 21 General Installation Instructions Typical Installation WARNING: Turn off power source before installing or adjusting this device. Failure to turn off power could result in serious or fatal electrical shock. 1. Determine the mounting location for the control panel. Liquid-tight connectors should be used on all cables entering panel. Conduit connectors, if used, must be sealed. 2. Check local codes and the schematic for power circuit requirements. On the control panel, determine the “power in” location (from the building power supply). CAUTION: BE SURE THE POWER SUPPLY VOLTAGE AND PHASE ARE THE SAME AS THE PUMP MOTORS BEING INSTALLED. 3. Determine the location on the control panel for the pump power cables and float switch cables. Drill holes to fit the type of cable fittings to be used. 4. Attach floats as shown in Typical Installation drawing. 5. Following step-by-step instructions and wiring diagram included with panel, complete connections of all cables. 6. Follow “Manual Testing” procedure in instruction manual. NOTE: Little Giant Pump Company cannot be responsible for damages caused by faulty or negligent installation of this control.
