1.4 ACCESS TO ELECTRICAL AND PNEUMATIC CONTROLS
WARNING!
Ensure power supply is off and disconnected before proceeding.
To access the electronic circuit board for installation or service of
the REAMER, simply loosen the 4 Allen head screws and
remove rear motor shroud for access to switches.
To reinstall the covers, place motor shroud into position and
tighten the 4 Allen screws.

1.6 L.E.D. INDICATORS
The L.E.D. indicators mounted on the front of the reamer supply visual information regarding cycle
status. This information may be used for both installation and maintenance to verify proper
operation. When REAMER is idle, L.E.D. status should be:
"Reamer Home" - ON
"Reamer Ahead" - Off
"Unclamped" - ON
"Reamer Home"
- indicates that the lift cylinder has retracted, the cutter is at the bottom of its
stroke and the limit pin is activating the lower limit switch.
"Reamer Ahead"
- indicates that the Reamer has reached full upper stroke and the limit pin is
activating the upper limit switch.
NOTE:
Full stroke extension of the lift cylinder is 3/8" (9 mm) shorter in the automatic mode. Use
the insertion depth chart in section 2.1 for proper depth. If manual set-up is used (Section 2.4) for
insertion depth, cutter may not travel deep enough.
"Unclamped"
- indicates that the clamp cylinder is fully retracted, releasing the clamp mechanism
and supplying an output signal that the cycle is complete (via the limit switch mounted next to the
clamp cylinder)
CAUTION! Before start-up ensure all connections are correct or damage to the TOUGH GUN REAMER
may occur.
NOTE:
The TOUGH GUN® REAMER is factory set for sourcing inputs and outputs.
The control logic requirement for some installations may require an inverse of the logic provided. The inverse logic is 0 VDC
low (sinking) input or outputs.
To switch from sourcing to sinking, the switches located inside the motor shroud must be accessed. Refer to “Access to
Pneumatic and Electrical Controls (see above) for directions.
Although the circuit board is protected, Tregaskiss suggests disconnecting the power before moving the switches.
The switches are located on the bottom right hand corner of the circuit board.
The output signal (unclamped signal) can be altered to either sourcing (high) or sinking (low) by moving the switch (SW3) to
the position indicated on the diagram. (page 10)
The input signal (start signal) can be altered to either sourcing (high) or sinking (low) by moving the switch (SW2) to position
indicated on the diagram. (page 10)
The Option signal (sprayer) can be altered to either sourcing (high) or sinking (low) by moving the switch (SW1) to position
indicated on the diagram. (page 10)
