Equipment Needed • Equipment Needed : – 1/2” and 1 1/4” hole punch and rubber grommets. – Power drill with bits. CAUTION! Do not use electric drill around LPG. – Assorted bolts and nuts for mounting to truck cab floor - length determined by the thickness of the cab floor. – Digital Voltmeter. – Pliers – Screwdrivers – Socket and Allen wrenches – Wire cutters – Wire strippers – Electrical tape – Pipe dope – Wire ties – Make arrangements to have the meter calibrated after installation.
General Instructions • General Instructions: – Unpack - Immediately upon receipt – Carefully unpack F-RAMS® & 2100 - Always handle with care. Do Not Drop. – Remove and inspect the F-RAMS® unit and all of its parts , checking that no damage has occurred during shipping. – Match the parts against the packing slip to ensure all parts have been included. Note: For installation instructions for the meter and valve, refer to the manufacturer’s meter/valve manuals.
F-RAMS® Operating Specifications • Pre-Installation Electrical Checklist: – Operating Specifications: • • • • • Idle State (not delivering product) ……. 1 Amp Delivery Solenoids ……. 1 Amp Printer ……. 1 Amp Safety Factor …….
Pre-Installation Checklist • Pre-Installation Electrical Checklist (cont.): – For proper operation of the F-RAMS® system, the truck electrical system must meet the following requirements. • Battery terminals and cables must be in good condition with clean, corrosion free connections. • Battery must be charged in accordance with manufacturer’s specifications. • Alternator output must meet total truck demand under normal use ( i.e. lights,heater,radio,hose reel, lifts etc.
VOLTAGE CHECKS • To check the voltage requirements: – – With the truck turned off - Use a Digital voltmeter and measure across the battery to determine the battery voltage - Minimum 12.5 VDC. (This will tell you if there is a drain on the battery). Record Voltage: _________ With the truck operating - Use a voltmeter and measure across the battery to determine the battery voltage - Minimum of 12.67 VDC to 13.87 VDC. (This will tell you if there is a drain on the battery.
MOUNTING BRACKET • MCU Mounting Bracket Location – The MCU can be mounted either on the back wall of the cab or underneath the passenger seat. The recommended location is on the back wall of the cab. – When running the fiber optic cable to the back of the truck, drill a hole through the back of the cab or through the floor board. CAUTION: Be sure to install grommets to the holes so the truck vibration does not cut through the cable. Battery Cable Acc.

CABLES • Wiring Cables – To make the installation easier, each F-RAMS® is shipped with 3 quick connect wiring cables. This kit is made up of several cables. – (1) MCU wiring cable ------ 3 conductor 18 gage ( White --- 12VDC,Green --ACC, and Black --- GND ) Note: Runs from the fuse box and the terminal strip. – (2) I.S.

CABLE ROUTING • Routing the cable – – – Drill 1/2 inch hole Make sure that the fiber optic cables that exit the cab have protection over their connectors to keep them clean. Punch a 1/2” hole in the cab for wiring exit. On tilt-cab trucks make sure to leave enough slack in the cable for maintenance access. Push the connector with its protective end (covers) through the hole and route to the RDU, storing any excess cable inside the truck cab.
FLOW METER CONNECTION • Flow Meter Connection – – Route the fiber optic cable from the back of the MCU unit to the RDU unit which is located on top of the flow meter. Avoid suspension parts, i.e. shocks, springs, etc. which can crush the cable. Stay as far away from heat sources (engine exhaust manifold, mufflers, tail pipes, etc.) as possible. Running the cable down the inside edge of the frame will provide maximum protection. Secure every 18 - 24 inches with ties (or equivalent).
RDU Rear Connection • RDU Rear Connection – Remove (6) Seal screws holding the back panel of the RDU. This will expose the inside of the RDU with the following connectors: • MCU Fiber Optic communication cable (1) pair -- Orange, Blue • I.S.Power cable (1) pair --- White 12 volts (Switch hot), Black (GND). • [Optional] RTD Probe cable (3) wires --2 - Reds, 1 - White (Only used on temperature compensated systems.) • [Optional] Valve Fiber Optic cable (1) Blue Fiber Optic. (Only used on systems with valves.

Tilt Cabs • Cab-over Trucks – Be careful when locating the exit points of the fiber optic cable from the RDU. The entrance point must be as close to the pivot point of the cab as possible. A position on the line with MCU will keep the harness out of the way. Be sure to allow enough slack to accommodate pivoting of the cab. – For convenience, a 35-foot fiber optic cable along with optional lengths of 25, 20, and 15-foot cable are available.
Conventional Cab
CAB HOOK-UP • ACC. hook-up and 12VDC hook-up – First locate the ACC. position on the fuse box by using a trouble light or a volt meter. – With the truck turned OFF, connect the test light, by connecting the alligator clip to ground. Use the other end of the test light to touch the end of the fuse. • Note: The test light will light when you come in contact with a 12 volt source. – After locating an ACC. line, test to ensue that it is a true ACC. • Note: If it is a ACC.
