PRYCO, INC. 0 0 FUEL CONTROL MONITORING (FCM) SYSTEM The FUEL CONTROL and MONITORING (FCM) system, is totally solid state electronic except for a fail- safe critical high fuel level switch. The FCM system uses an ultra -sonic sensor to accurately determine the level of the fuel. It is specially designed for Pryco for this type of environment. Through electronic "action levels" the FCM controls the activities of up to four pumps and motors. It also controls and provides a signal for a full array of external alarms and similar devices based upon predetermined levels. The action levels shown in the table below represent a "normal' setup — changes may be made providing the integrity of a sequence of operation is not violated. Standard Features in- clude: * Ultra -Sonic Sensor - 4-20 ma * Control Panel Alarm Reset Switch * 24vdc Input For Continuous Operation * Control Panel Alarm Silence Switch * Power Available LED * Safety High Switch w/Fill Motor Shut Off * System Ready LED * High Fuel Level Notification * Electronic Fuel Gauge * Low Fuel Level Notification * HOA Switches * "Dry Tank" Prevention * Control Panel System Test Switch Option .. 700 FUEL CONTROL AND MONITORING SYSTEM — electronic circuit boards, ultra -sonic sensor, and related components to control and monitor all activities on the fuel system. 706 CRITICAL LOW LEVEL ALARM — Activates red light on control panel, provides signal for remote annunciation and engine shut down (prevents loss of engine fuel prime). 734 COVER—DAY TANK w/FCM, NEMA -1 734-1 SINGLE—one pump and motor 734-2 DUPLEX—two pumps and motors 734-3 TRIPLEX—three pumps and motors 734-4 QUAD—four pumps and motors 727 DUPLEX FILL PUMP and MOTOR — (addition to standard pump and motor) secondary "lag" pump/ motor system to back-up primary "lead" pump/motor. Normally the lead pump/motor begins operation at 86% usable fuel capacity; the lag system begins at 82%. Both systems turn off at 100% capacity. 727A DUPLEX FILL PUMP and MOTOR w/AUTOMATIC ALTERNATING LEAD/LAG — Same as Option 727 with a switch to automatically alternate each pump/motor into the lead starting position. 773 PUMP(s) FAIL DETECTION w/AUTOMATIC and MANUAL RESET — Includes: the control panel switch, an in-line flow switch, and other required items necessary to detect, report, and reset a "no fuel in line" condition (one per pump). A flow switch, option #372, is required. 780 FCM POWER SUPPLY PROTECTION — Line Conditioner and noise suppression with battery backup to protect FCM electronics and circuits from damaging "brown outs" and spikes. 799 REVERSE FLOW CONTROLS for OPTIONAL PUMP and MOTOR — Controls and piping necessary for a reverse flow single pump/motor (sold separately) to pump fuel back to main storage tank to prevent overfill. This system begins operation at a level above the fill pump(s) normal turn-off point. 799A DUPLEX REVERSE FLOW PUMP and MOTOR w/AUTOMATIC ALTERNATING LEAD/LAG — Two sets of controls and piping necessary for two reverse flow pumps/motors to pump fuel back to main storage tank to prevent overfill. (The pumps and motors are sold separately.) The "lead" system begins operation at a level above the fill pump(s) turn-off point – the "lag" system begins at a level above the lead system (provides assistance and backup). Page 32 P.O.
