How to Clear Boom Safety
Switch Faults
Note: Beginning with software release 3.0, the
boom envelope switches will latch and faults
must be reset in software or through the use of
the TCON LCD. They will not clear by re-powering
the machine.
Note: There are two methods to reset the faults,
by using Web GPI or through the menu available
on the TCON LCD.
Using Web GPI
1 Connect the device containing the WEB GPI
software to the TCON with an RS-232 cable.
2 Select the Safety folder, then the Fault Status
screen.
3 Change any safety switch drop down menus
displaying
FAULT to OK. Press SEND.
4 Exit Web GPI.
Using the TCON LCD
Note: Take care when using this method to avoid
resetting threshold defaults.
1 With the key switch off, press and hold the
button and turn the key switch to the on
position. Release the button after five
seconds and press the buttons.
2 Press the
button until CLEAR ALL SAFETY
SWITCH
FAULTS appears.
3 Select YES, then press the button.
4 Press the button until EXIT appears.
5 Select YES, then press the button.
Note: This clears all latching faults, not standard
faults.
