Manual Operation
Drag Pressure:
Drag pressure should be determined using the following procedure:
Å
Move the carriage so that the faced pipe ends are approximately 3.5" apart.
Å
Touch the carriage control valve middle (neutral) position.
Å
Touch the heating mode, and set the middle pressure reducing valve to its lowest pressure.
Å
Touch the carriage control valve left direction.
Å
Increase the pressure on the middle reducing valve until the carriage moves.
Å
Reduce the heating pressure valve until the carriage is just barely moving.
Å
Record this actual drag pressure and add it to the calculated theoretical fusion pressure and set the fusion pressure to that value.
Check Alignment:
Check the alignment of the pipe using the following procedure:
Å
With the pipe ends together under facing pressure, observe the outside diameter
of the pipe ends for alignment.
Å
If the pipe ends are not in alignment, increase the pressure of the jaw clamps of
the pipe on the low side using Machine Controls screen.
Slip Check:
Perform a slip check using the following procedure:
Å
Touch the fusion pressure position on the pressure selector.
Å
Close the carriage by touching the far left position of the carriage control valve.
Å
Observe if the pipe slips in the jaws of the carriage. If the pipe slips, the pipe
will need to be reloaded and facing procedures repeated.
Å
Open the carriage completely by touch the carriage control valve right
direction.
