Connect either clamp connector for the power cable to the positive (+) post of the battery and the other clamp connector to the machine chassis.
TS4 Pulse Generator.The control unit can be calibrated (adjusted) with a TS4 Pulse Generator made by Flo-tech, Inc., 403 Washington Blvd., Mundelein, Illinois 60060, or a similar pulse generator. To calibrate the unit, remove the plate on the end of the control unit opposite the handle.
All of the components of the new flow meter except the flow block can be put in the lid for the control unit when the flow meter is not used. With the components in the lid and the lid installed on control unit, the new flow meter is compact (in a small package) and portable (can be moved around by hand).
The 5P7360 Tachometer Generator Assembly is the replacement for the former 9S3047 Tachometer Generator Assembly. The former tachometer generator was connected to ground through its housing, while the new tachometer generator is not connected to ground. The new tachometer generator has a black color.
Do not use the former 9S3047 Tachometer Generator Assembly with the 5P3600 Hydraulic Flow Meter Group.
Plate removed on end of control unit to make calibration.
Components of flow meter installed in lid for control unit.
5P3600 Hydraulic Flow-Meter Group ready to be moved.The flow valve in the flow block is controlled at the control unit. The flow valve will automatically open if the engine is stopped. It will also automatically open during installation of the flow meter when the electric cables are connected. The valve in the former flow meter was operated manually. If the flow valve sticks (will not operate), remove the rubber plug in the end of the flow block. Turn the valve shaft with a wide blade screwdriver.
The flow block has a 9S6341 Safety Disc.
Always be sure the correct safety disc is used in the flow block. When testing machines with relief valve pressures above 3000 psi (20700 kPa), install a 1P7411 Safety Disc in the flow block. When testing machines with relief valve pressures below 3000 psi (20700 kPa), install a 9S6341 Safety Disc in the flow block.
Arrow gives location of rubber block in flow block.The flow block has a check valve for the small pressure hose to the control unit. The check valve will keep leakage to a minimum if the small pressure hose breaks or if a connection leaks. The inlet and outlet connections for the hydraulic lines in the flow block have 1 5/8"-12 threads. The connections are more compact than on the former flow meter. Also, the connections can be fastened faster and easier than on the former flow meter.
