DIGITAL GREASE CONTROL VALVE OWNER’S MANUAL
2. INSTALLATION PROCESS
WARNING:
To reduce the risk of serious injury, the pressure relief should be done very
carefully. Follow the
PRESSURE RELIEF PROCEDURE
in
OPERATION INSTRUCTIONS
section.
WARNING:
Make sure the whole system is clean before installing/ replacing a new
control valve. No impurities or contaminant are allowed to enter the control valve.
(1) Installing the new grease control valves
Follow the following steps to clean the grease supplying system before a new control valve is
installed. (The system also needs cleaning when the grease in the system is polluted).
①
. Turn off the check valve before each dispensing point in the system.
②
. Turn off the check valve close to the grease pump outlet.
③
. Turn off the check valve in the air line. Lower the air inlet pressure, and then open the air line
check valve again, so that the grease pump is ready to work.
④
. Slowly open the check valves close to the grease pump
outlet and then the check valve to the dispensing point
to drain the grease to a waste tank.
⑤
. If there are several dispensing points, you need to drain the
grease at each point, one by one, starting with the furthest
one from the pump, and ending with the nearest one to the
pump.
⑥
. When installing a new control valve, first apply appropriate
sealing glue around the male thread of grease supplying
system, then connect the male thread into the female thread
of grease inlet of the control valve, and fix them together.
⑦
. Turn on all check valves of grease system.
⑧
. Press the trigger to drain enough grease to make sure the grease system is completely
cleaned. See “OPERATION INSTRUCTIONS” section for the control valve operation.
⑨
. Repeat steps
⑥
to
⑧
for other grease control valves to be installed at each dispensing point
in the system.
(2) Replacing grease control valve
①
. Disconnect and take the grease control valve off the system.
②
. Follow the steps
⑥
to
⑨
in “(1) Installing the new grease control valve" section above.
OPERATION INSTRUCTIONS
1. PRESSURE RELIEF PROCEDURE
WARNING:
Skin injection hazard: The equipment stays pressurized until pressure is
manually relieved. To reduce the risk of serious injury from pressurized fluid, fluid from the valve
or splashing fluid, follow this procedure whenever you:
• Are instructed to relieve pressure
• Stop dispensing
• Check, clean or service any system equipment
• Install or clean dispensing devices
(1) Pressure relief procedure
①
. Close the pump air regulator and the bleed-type master air valve.
②
. Hold a metal part of the dispensing valve firmly to a grounded metal waste container and
trigger the valve to relieve the fluid pressure.
③
. Open the air line valve and grease line valve.
④
. Close the control valve after the pressure is relieved.

(2) Clean the obstruction in the grease system, when any of the following cases occurs:
①
. Problem on control valve, flexible hose, rigid tube or manual/auto tip.
②
. Pressure can not be relieved enough after above procedures are done.
③
. It takes more than 5 seconds to relieve the pressure thoroughly.
2. LCD DISPLAY
INDICATIONS: See the following displaying illustration
of the LCD panel.
①
. Partial register (4 figures with moving comma from
0.1 to 999.9): Measurement exceeds the maximum
value will become zero and re-measure.
②
. Battery condition (Low-power alarm device is built in.)
③
. Model identification
④
. Indication of resettable total or total register
⑤
. Resettable total or total register (Total register can
not reset; 7 figures with moving comma from 1 to 99999.9)
⑥
. Indication of flow rate mode
⑦
. Indication of unit of measurement of partial (oz, g)
⑧
. Indication of unit of measurement of total (Ib, kg)
3. OPERATIONAL FUNCTIONS
The control valve features two keys (MENU and RESET).
(1) Setting measurement unit
①
. Press “MENU” and “RESET” simultaneously and hold for about 5 seconds to enter the unit set mode.
②
. Press "RESET" to select the unit.
③
. When desired measurement unit is displayed, press “MENU” and hold about 1 second or the
digit stops blink to quit the setting mode.
(2) Resetting the present total
Press "RESET", full-screen shows. After about 1 second, the display shows “0.0”.
(3) Displaying current correction factor and general total
Press “MENU” and “RESET” simultaneously and hold for 2 seconds. The display shows the
correction factor and total value.
4. CALIBRATION PROCEDURE
(1) Procedure for entering the correction factor directly
①
. Wait for the control valve to go to standby.
②
. Press the “MENU” key. Keep it pressed until the digit flashes in Zone
①
. Press the “RESET”
key to choose the right digit from 0 to 9. Press the “MENU” key to go the next digit so that the
Actual Value can be input.
③
. Make sure the correction factor is right and then press the “MENU” key. Keep it pressed until
calibration is finished and the factor is saved. The control valve will then return to standby.
(2) Modify the correction factor in field
①
. Press the “RESET” for 1 second, Zone
①
displays “0.00”.
②
. Start dispensing into a container whose weight is known.
③
. Stop dispensing when over two-thirds of volume is reached, weigh the container for gross
weight and minus the tare weight of the container to get the net weight. The weight that is
displayed on the LCD is the Display Value, not the Actual Value. The net weight of the grease
is the Actual Value.
④
. Press the “MENU” key. Keep it pressed until the digit flashes in Zone
①
. Then press the
RESET key to choose the right digit from 0 to 9. Press the “MENU” key to go the next digit so
that the Actual Value can be input.
⑤
. Make sure the Actual Value is input right and then press the “MENU” key. Keep it pressed until
calibration is finished and the factor is saved. The meter will then return to standby.
