Installation

WARNING

To reduce the risk of serious injury, including elec-

tric shock or splashing fluid in the eyes or on the

skin, always follow this procedure before servicing

any part of the metering system and before check-

ing for loose or shorted wires.

1. Turn off the control, and unplug it.

2. Shut off the power to the pump(s).

3. Relieve the fluid pressure.

CAUTION

To avoid damaging the electronic components of the

pulse meter module (1)

DDo not lay anything on the module.

DBe sure the open side of the pulse module faces

up if you lay it down.

DDo not twist or force parts. Align parts properly

as instructed.

NOTE: All pulse meters are bi-directional.

To Install or Remove the Complete Pulse Meter

1. Observe the Warning and Caution above.

2. Disconnect the cable from the pulse module,

taking note of the wiring polarity.

3. Remove the old pulse meter and install the new

one, observing the original wiring polarity.

To Replace the Electronic Pulse Module

4. Observe the Warning and Caution at left.

5. If you are replacing the pulse module, disconnect

the cable, taking note of the wiring polarity.

6. Remove the screws, and lift off the pulse module.

7. Install a new pulse module (1). Align the notch on

the side of the pulse module with the notch on the

side of the metering unit. Use the new screws and

torque them oppositely and evenly to 3 to 5 in-lb

(0.34 to 0.57 N.m). See Fig. NO TAG.

8. Connect the pulse module wires to the cable,

observing the original wiring polarity.

To Verify the Accuracy of a Pulse Meter

Module

1. Use a clean, calibrated container. If using a single

container, be sure to clean it after each dispense.

2. Have pump air pressure at the lowest possible

setting for dispensing fluid.

3. Put the tip of the nozzle at the bottom of the

calibrated container.

4. If the tip of the dispense valve does not reach the

bottom of the calibrated container, use a length of

plastic tubing over the tip of the nozzle to ensure

liquid enters the container from the bottom.

5. Trigger the gun slowly so the fluid immediately

covers the tip of the dispense valve.

6. Dispense 1 quart of fluid according to the metered

display on the dispense valve.

7. Allow product to sit for 20 minutes, then compare

the actual, physical measurement in the calibrated

container to the measurement displayed on the

meter.

NOTE: The procedure above will determine if the

meter is accurately dispensing the product and mini-

mize testing errors. Some variance may occur depend-

ing on the viscosity of the fluid. If this procedure deter-

mines that the meter is not accurate, recalibrate the

meter as described in the service manual or replace

the meter or the electronics as necessary.
