SECTION 5 — OPERATION
5-1 Understanding L.E.D. Indicators
The L.E.D. indicators mounted on the circuit board of the TOUGH
GUN Reamer supply visual information regarding cycle status.
This information may be used for both installation and
maintenance to verify proper operation. When the TOUGH GUN
Reamer is Home, L.E.D. status should appear as labeled in the
chart and diagram below.
REAMER HOME
ON
Indicates that the lift cylinder has
retracted, the cutter is at the bottom of
its stroke, the limit pin is activating the
lower limit switch and the clamps are
open and the lower limit switch is
working properly.
CLAMP /
MOTOR VALVE
SHORT
OFF
Indicates short with clamp or motor
valve when ‘ON’.
REAMER AHEAD
OFF
Indicates that the TOUGH GUN Reamer
has reached full upper stroke and the
limit pin is activating the upper limit
switch. Unless the Reamer gets stuck at
the top, this L.E.D. will only be ‘ON’ for
a split second before the unit begins to
retract and the L.E.D. turns ‘OFF’.
SPRAYER VALVE
SHORT
OFF
Indicates short with one of the sprayer
valves when ‘ON’.
UNCLAMPED
ON
Indicates that the clamp cylinder is fully
retracted, releasing the clamp
mechanism (via the clamp limit switch).
FEED VALVE
SHORT
OFF
Indicates short with feed valve (also
referred to as “spindle valve”) when
‘ON’.
