9 CALIBRATION (CONT.)
9.4 Stage 4 - Set Maximum Moment
With the machine set to the maximum radius combination of the boom, dipper or any
extending boom fitted, and apply the maximum load rated for that machine at the maximum
radius position. This represents the Maximum Moment allowed.
Ensure the magnet is fitted on the top of the display as shown on page 14. The Display will
be in Indicator mode. (Probably just bottom green “Power On” indicator lit.)
Press and hold the RED test button for more than 3 seconds to enter the Calibrate mode. All
the LEDs come on to show it is now in Calibrate mode. Release the Red button and the top
! Red and bottom green Power On LEDs are lit, as well as the 50% Green LED. This indicates
that it is in “Maximum Moment” set-up mode.
!!
DON’T REMOVE THE MAGNET !!
REMOVING IT, OR NO ACTIVITY FOR 100 SECS WILL EXIT THE CALIBRATE MODE.
Press & hold the Red button for over 2 secs to make the Series 1-L Acquire & Store the
“Maximum Moment” pressure, showing the MAXIMUM MOMENT state.
Now release the button. All the LEDs should come on momentarily, then all but the Green
Power On LED go off before all the LEDs come on momentarily again to confirm the Zero
Pressure has been acquired & stored.
The unit will then go from Calibration mode to Indicator mode with all the LEDs lit as the
machine is in a maximum moment condition. Reduce the load to return normal operation.
Repeat with Duty Input set to Duty 2 (Duty input, white wire, grounded or connected to 0V)
if a second duty is to be used.
THE Series 1-L IS NOW CALIBRATED.
NOTE: REMOVE THE MAGNET SO THAT THE CALIBRATION CANNOT BE MODIFIED.
9.5 Verification
To verify the calibration, select random positions & lift duties. Check overload warning
against tip load.
