9.0 MANUAL OPERATION
9.1 Pressure Adjustment - Manual Mode
WARNING
Failure to observe and comply with the following precautions
could result in death or serious personal injury. Property
damage could also occur.
• Always make pressure adjustments before putting torque
wrench on nut or bolt head.
• Pressure setting must be adjusted to provide the correct
torque and to ensure that excessive torque is not applied.
• Do not adjust pressure settings while pump is in use.
1. Press and hold the red pendant button. Refer to Figure 4.
2. While holding the red pendant button, press and hold the
yellow pendant button. The pendant LED indicator light will
blink red twice and the pendant will vibrate.
NOTICE
Steps 1 and 2 reset the stored pressure to zero (0)
psi/bar if a stored pressure had been previously set. It is not
necessary to reset stored pressure. Manual mode will still function
if a pressure is stored, but pump pressure will not exceed the
stored pressure.
3. Loosen the relief valve locknut and turn the relief valve
adjustment knob counterclockwise until there is a light drag
when turning. Refer to Figure 7.
4. Press and hold the green pendant button to start pump
motor.
NOTICE
The green pendant button must be held down during
the entirety of steps 5 through 8. Releasing the green pendant
button will stop pump motor.
5. Turn the relief valve adjustment knob clockwise to increase
pressure to desired value.
NOTICE
To obtain an accurate setting, decrease the pressure
to a point below the final setting and then slowly increase the
pressure until it reaches the final setting.
6. Tighten the relief valve locknut when the pressure gauge
reading is stable and is at the desired pressure.
7. Release the green pendant button.
8. Recheck the final pressure setting by holding the green
pendant button and pressurizing the system.
9. If the final pressure setting is not at the desired setting, then
repeat the procedure described in steps 3 through 8. If the
final pressure setting is at the desired setting, then proceed
to step 10.
10. Press and hold the green pendant button. When the pump
reaches the previously set pressure, press the yellow pendant
button.
11. Release the yellow and green pendant buttons.
12. The pendant LED indicator light will blink yellow and the
pendant will vibrate three times when stored pressure is
recorded.
NOTICE
The pump will save the stored pressure (within the
available range of 1,000 to 10,000 psi [70 to 700 bar]) even after
long periods of non-use.
9.2 Torquing - Manual Mode
1. Place torque wrench on nut or bolt.
2. Press and hold the green pendant button to begin an
advance cycle. Pendant will vibrate and the indicator light
will blink green until within ±250 psi [17 bar] of the stored
pressure is reached.
NOTICE
• If stored pressure was reset and a new setting was not entered,
the pump will continue to build pressure until the manual relief
valve setting (Section 9.1 step 6) is reached.
• If stored pressure exists and pump is run in manual mode,
then:
- Pendant LED indicator light blinks green if pressure is
below
stored pressure value.
- Pendant LED indicator light blinks yellow if pressure is
equal
to
stored pressure value.
- Pendant LED indicator light blinks red if pressure is
above
stored pressure value.
• The pump can be run in manual mode without entering a
stored pressure setting. If there is no stored pressure setting,
the pump pressure will build until it reaches the manual relief
valve setting.
• The pendant LED indicator light will blink green and the
pendant will vibrate once when the pump motor is turned on.
• The pendant will vibrate twice when the pump motor stops.
• If relief pressure is achieved before the torque wrench fully
advances, then desired torque has been achieved.
• If relief pressure is not achieved before the torque wrench fully
advances, then the desired torque has not been achieved and
further cycles are required.
3. Release green pendant button to start a retract cycle.
4. Repeat steps 2 and 3 until target torque is achieved.
5. If inputs from the pendant are not received within three
seconds of completing a retract cycle, then the pump will
automatically dump all remaining system pressure and turn
off.
10.0 DEPRESSURIZING THE SYSTEM
The pump automatically dumps system pressure whenever the
pump motor stops whether manually or automatically under
normal operating conditions. If pressure is trapped, to manually
relieve pressure perform the following procedure:
NOTICE
The pump must be connected to an AC power source
for this procedure.
1. Be sure the pump motor is off.
2. Press and hold the red pendant button. Refer to Figure 4.
3. While holding the red pendant button, press and hold the
green pendant button. Pressure gauge should now show
zero (0) psi/bar.
4. After the pressure gauge shows zero (0) psi/bar, release red
and green pendant buttons.
