Note: Perform this procedure with the machine on
a firm, level surface with the boom in the stowed
position.
1 Connect a 0 to 5000 psi / 0 to 350 bar
pressure gauge to test port #1 (TP1) on the
function manifold.
2 Turn the key switch to Ground control. Pull
out the platform red Emergency Stop button
to the on position and pull out the ground
control red Emergency stop button to the on
position.
3 To enter the pressure sensor calibration
mode, momentarily activate the ground
control function enable switch three times
within 5 seconds of pulling the red Emergency
Stop button at the ground controls.
The pump motor activates and a green light
flashes on the TCON controller. The ground
display shows the current calibration steps
along the entire procedure.
Note: The procedure will time out if any step is not
completed within 120 seconds or terminate if the
function enable switch is activated.
4 Activate the platform level toggle switch in the
up direction to increase the relief pressure or
in the down direction to decrease the relief
pressure until the pressure gauge reads
1000 psi / 69 bar.
5 Activate the platform rotate toggle switch to
store the value.
Result: The control system will continue to the
next calibration procedure value - (3000 psi /
207 bar).
6 Activate the platform level toggle switch in the
up direction to increase the relief pressure or
in the down direction to decrease the relief
pressure until the pressure gauge reads
3000 psi / 207 bar.
7 Activate the platform rotate toggle switch to
save the value.
Result: The control system will automatically
continue through the procedure and it
automatically sweeps the following calibration
values: 2500 PSI / 172 bar, 2000 PSI /
138 bar, and 750 psi / 52 bar.
Note: Wait until it displays "CONN.OTP" which
indicates that all the pressure values are
calibrated.
8 Disconnect the pressure gauge and connect
to the Oscillate Port (OSC) such as 0 to
1000 psi / 69 bar pressure gauge or the digital
meter.
9 Activate the platform rotate toggle switch.
Result: The display shows the next calibration
value for the oscillate line.
10 Activate the platform level toggle switch in the
up direction to increase the relief pressure or
in the down direction to decrease the relief
pressure until the pressure gauge reads
600 psi / 41.3 bar.
11 Activate the platform rotate toggle switch to
save the value.
The control system will continue to the next
calibration procedure value - (520 psi /
35.9 bar).
12 Activate the platform level toggle switch in the
up direction to increase the relief pressure or
in the down direction to decrease the relief
pressure until the pressure gauge reads
520 psi / 35.9 bar.
13 Activate the platform rotate toggle switch to
save the value.
A one second pulse alarm will indicate the
calibration procedure is complete.
