Electrical Check Before beginning to install the LectroCount , it is essential that you complete the following checklist. If the vehicle electrical system cannot meet the following requirements, corrective action must be taken before installing the LectroCount . This checklist is also included with the system. That copy should be filled out and filed with the distributor or truck builder.
Truck Cab Computer Installation GENERAL REQUIREMENTS Truck Cab A minimal truck cab computer system Component Configuration includes: 1. A supervisory control module (SCM) that is mounted between two right angle brackets 2. A dot matrix ticket printer 3. A Lap Pad (key pad/display). Systems equipped with the RAM card option will have a RAM interface module mounted atop the supervisory control...

5.4.2 Installation of Ground Strap Kit Locate a good ground point near the back of the seat frame. The bottom of the seat base bracket is usually a good spot. Drill a 9/32” hole in the seat frame near the back of the base. Attach one end of the ground strap to the bracket using the lock washer, flat washer and nut provided.

Supervisory Control Module Grounding The Supervisory Control Module (SCM) case must be grounded to a good chassis ground on the truck to ensure proper operation. Usually, a good ground path is established from the SCM case through the mounting brackets and bolts to the chassis.
If the resistance is less than 3 ohms: The system is grounded sufficiently and no further action is necessary. If the resistance is greater than 3 ohms: A grounding strap needs to be attached between the mounting bracket and a good ground in the cab.
7. Lap Pad Connection The “D” connector on the end of the Lap Pad’s coiled cable should be plugged into the socket labeled “Lap Pad” on the front of the supervisory console. Tighten the two captive screws on the connector to hold it in place.

INSTALLATION OF STRAINER COVER MOUNTED THERMOWELLS (CONT.) The aluminum thermowell will be used for the 3-wire platinum RTD temperature probe. Before inserting the probe into the aluminum thermowell, thoroughly coat the entire probe length with the copper, heat transfer grease that is supplied.
10.2 INSTALLATION OF PIPE MOUNTED THERMOWELLS Re-coat the RTD probe with the Thermowells can also be installed in half grease and insert it into the couplings that are welded in place on thermowell for the final time, the fluid line. positioning it as far down in the thermowell as possible.
Controls to facilitate the RSCB installation on many industry standard meters. 11.1 LIQUID CONTROLS METERS/RSCB WITH INTERNAL PULSERS The internal pulser version of the RSCB allows traditional mechanical registration equipment to be easily replaced with the LectroCount³ electronic register. (Requires Part Number 81369 Mounting Kit, LC Meter)
Remove the cotter pin from the drive the Drive Shaft Adapter to the Pulser Drive Shaft, with a cotter pin item shaft on the bottom of the RSCB, taking care not to lose the washer. Avoid pushing shaft into housing Place the RSCB on the counter until drive shaft adapter, item #1, is bracket, sliding the drive shaft...
11.3 NEPTUNE NON-COMPENSATED METER RETROFIT Field Installation / Replacement of Register Stack With RSCB Using 81364 Neptune Mounting Kit Remove all of the mechanical register components from the meter. Leave just the star-shaped gear and the two square-headed studs. Screw the two cone-tipped clamping screws, (item #7) into sides of adapter bracket, (item #6), until the conical tip is protruding inside of the bracket.
11.4 NEPTUNE TEMPERATURE COMPENSATED METER RETROFIT KIT Remove the mechanical registration equipment and the mechanical Temperature Volume Compensator from the top of the meter. Remove the cotter pin from the drive shaft on the bottom of the RSCB, taking care not to lose the washer. Position the adapter shaft (item #2) over the pulser shaft.
Terminal block numbers, signal functions, and wire colors can be found there. Please read the special notes listed on the drawing. Liquid Controls will not honor any warranty claims for damage due to negligence during the installation of the system.
12. Wiring the RSCB Once the control valves, pulser, and ETVC kit (if so equipped) have been mechanically installed, they need to be wired to the RSCB. The RSCB has seven ½” NPT ports to accommodate the wires and cables that enter it. Typically, the ports in the back are used for the signal cables that run to the truck cab and for the optional three-way solenoid.
Note: The numbers and wires on the wiring blocks face towards the outside of the box. 12.1 WIRING OF VALVE SOLENOIDS TO RSCB The solenoid conduit hubs should be It is recommended that red wire be used positioned to allow the conduit to be for main connections, though black can efficiently routed to the RSCB.
(S2) connects the bonnet to the outlet. The wires from S1 connect to terminal block J-4- SOL1. The wires from S2 connect to terminal block J-4-SOL2. 12.1.2 Liquid Controls Dual Stage Valve Wiring (Part Number: A284811 for 2") Solenoid S1 is hard piped to the top of the differential valve and represents the first stage of the closure.
12.5 TRUCK CAB CABLE ROUTING The RSCB is supplied with a cable assembly, consisting of two cables, which connect it to the truck computer. The two cables are terminated on the RSCB end with connectors that have been routed through RSCB hubs and connected to the RSCB circuit board at locations J1 and J6. On the cab side of the cable assembly, the two cables join in a black 16 pin circular connector.
