WARNING
Do not allow any body part
to be trapped by equipment.
Body parts can be crushed
by subassemblies during
operation.
Failure to comply may result in death
or serious physical injury.
WARNING
Do not allow fluid to leak
onto floor when operating
equipment. If spill occurs,
clean any fluid on floor before continuing
operation.
Failure to comply may result in death
or serious personal injury.
Safety*
Read and carefully observe these installation
instructions before installing/operating/
troubleshooting the assembly. The assembly
must be installed, maintained and repaired
exclusively by persons familiar with the
instructions.
Always disconnect power source
(electricity, air or hydraulic) from the
equipment when it is not being used.
This equipment generates high pressure.
Extreme caution should be used when
operating this equipment as material leaks
from loose or ruptured components can
inject fluid through the skin and into the
body. If any fluid appears to penetrate the
skin, seek attention from a doctor
immediately. Do not treat injury as a simple
cut. Tell attending doctor exactly what type of
fluid was injected.
Any other use not in accordance with
instructions will result in loss of claim for
warranty or liability.
• Do not misuse, over-pressurize, modify
parts, use incompatible chemicals, fluids,
or use worn and/or damaged parts.
• Do not exceed the stated maximum
working pressure of the equipment or of
the lowest rated component in your
system.
• Always read and follow the manufacturer’s
recommendations regarding fluid
compatibility, and the use of protective
clothing and equipment.
• Failure to comply may result in personal
injury and/or damage to equipment.

*Indicates change.
Operation*
Fluid enters the inlet port (either end of the
meter) and passes through the metering
chamber. The force of the fluid causes the
internal gear assembly to rotate and forces
the fluid to exit through the outlet port.
Each full rotation of the gear assembly
displaces a given volume of fluid. Controlled
clearances between the gears and chamber
wall minimize leakage. One gear in the
assembly contains two magnets; one at each
end of the gear. See Fig. 4, page 6.
Use and maintenance
NOTE
Install a 40-micron or finer filter at the
inlet side of these meters.
Failure to comply may result in
damage to system, damage to
components, jammed gears, or
inaccurate readings.
These magnets activate a reed switch in
the switch module to open and close.
Contact closures from the switch are
transmitted as a signal to the remote batch
controller.
This transmitter is normally connected to
fluid managament metering systems that
have scaling capabilities and that can accept
a reed switch pulse.
Typical application is the Enterprise Fluid
Inventory Control and Management System
that accurately tracks, monitors and
dispenses fluids in vehicle service
applications.

Before assembly verify gears rotate
and do not bind. Manually turn gears
through three rotations to verify free
movement.
Meter will not function properly if
gears are incorrectly installed.
Assembly
Metering gears
1 Install gear (5) with magnets into
housing (3). Make sure to locate gear
properly in housing († Fig. 4, page 6).
2 Place second gear into housing. Verify
gear engages magnet gear as shown.
3 Rotate gear assembly by hand to make
sure gear teeth are properly engaged.
4 Install and seat o-ring (4) into oval
groove in housing.
5 Position housing cover (6) onto housing.
6 Install washers (7) and screws (8) that
secure housing cover to housing.
7 Tighten screws in a criss-cross pattern
to 90 in-lbf (10.2 Nm).

NOTE
Do not wire fluid solenoid incorrectly.
Wire polarity must be maintained
when connecting fluid solenoid. Red
wire is positive +and connects to
terminal 1 and black wire is negative
-and connects to terminal 2.
Failure to comply will result in damage
to equipment.
Fluid solenoid
Fluid solenoid valves contain diodes in their
connectors. This diode prevents electrical
surges from damaging relay contacts in the
keypad controller. Connections at fluid
solenoid valve are pre-wired († Fig. 6).
Fluid solenoid valve is normally closed and
pilot-operated. Valve is equipped with an
LED indicator and manual override.
When energized, valve opens and allows
fluid to be dispensed from control valve.
Fluid solenoid valves are suitable for
motor/gear oils, automatic transmission
fluid, antifreeze/water mix or windshield
washer fluid.
For complete instructions on fluid solenoid
valve 338315 refer to manual 671131.*

Operation
Valve assembly († Fig. 7) consists of two
separate internal valves; the primary needle
valve and the secondary valve. The primary
valve actuates first, causing the secondary
valve to operate.
When the coil is energized, the primary
needle valve lifts and allows fluid into
delivery port. Fluid pressure equalizes and
assists movement of secondary valve.
When energized, the valves poppet lifts to
open the port 2 to port 1 flow path, while
flow from port 1 to port 2 is severely
restricted.*
Manual override
To place valve in manual override mode,
push down on knob and turn counter-
clockwise 180°.
