side of the enclosure. Ready to accept your program, the
EtherNET card will operate using standard protocol and can be
configured to utilize your communication software program.
Contact your distributor or Sioux Tools, Inc. for assistance in
implementation.
DeviceNET
The TC50A will act as a standard node under the DeviceNET
proprietary protocol when this option is installed.
PFCS (Daimler Chrysler)
This optional communication protocol and hardware is available
from your distributor if the controller is being shipped to an
approved facility.
IX. SERVICE & WARRANTY
The TC50A is relatively service free in that there is no sched-
uled adjustments or maintenance needed. Insure that the air
supply is clean and filtered and that any lubricator is installed
between the controller and the air tool as oil will foul the main
valve and render the controller inoperable.
Should service be required, contact your local distributor or
Sioux Tools, Inc. at: Sioux Tools, Inc.

The standard WARRANTY term is one (1) year from date of
purchase. Sioux Tools, Inc. warrants the TC50A free from
defects in materials and workmanship and will repair or replace
the defective part(s) FOB the factory. To obtain WARRANTY
SERVICE, contact Sioux Tools, Inc. at 800-722-7290 or by fax
at 800-722-7236 to obtain an RGA number.
NO CONTROLLER WILL BE ACCEPTED FOR WAR-
RANTY SERVICE WITHOUT THE RGANUMBER
DISPLAYED ON THE SHIPPING LABEL.
X. ADJUSTMENTS - TRANSDUCER CALIBRATION
The TC50A is designed to accept industry standard, 2 Mv/v
strain gage torque transducers, either rotary or stationary types.
These are generally supplied with four or six pin Bendix style
connectors. If the controller does not calibrate once the full-
scale (at 2 Mv/v) setting is programmed, check the following:
• Cable and connections
• Millivolt rating of the transducer (some are 3 Mv/v and will
require a different full-scale value)
• Substitute a known good transducer to determine if the
transducer is defective or operate the transducer on a
portable meter to check its condition.
Should the transducer set-up correctly but the torque value not
agree with your “MASTER”:
• Check that the full scale of the transducer is correctly
entered
• Perform a CAL CORRECT routine
• Perform a fastening cycle using a MASTER transducer
for calibration
• Press the key under the ePro logo
• Press the DOWN key to enter the value from the
MASTER transducer readout
The readings from the TC50A and the MASTER will now agree.
Set-up Problems
During set-up, you may experience the inability for the controller
to function during one of the process steps. This is most likely
due to either too much or too little airflow signal and is indicated
by the controller not automatically accepting a reading. If you
have first determined that the supply air pressure and volume is
sufficient (90 psi @ 50 scfm), proceed with the following.
FLOW SIGNAL ADJUSTMENT SCREW
Through a small hole in the back cover, there is a Phillips #1
adjustment screw that can be user adjusted to obtain better
airflow signal. This flow adjustment will reduce or enlarge the
orifice through which the airflow passes. (NOTE: It is common
for this adjusting screw to “hiss” and will not cause the controller
to malfunction. However, should the screw come out during
adjustment, it will be necessary to remove the back cover to
replace it. A small amount of thread sealant (or Teflon tape) is
required to seal and hold the screw in place.)
This airflow adjustment screw operates over a range of (6-
7) turns from full-in to full-out. The FACTORY setting is (4)
turns out from seated. This default setting will operate 80%
of the common size tools from 9 - 80 Nm. If using tools
smaller or larger, make adjustments as per the following
instruction.
In general, very small tools require that the screw be rotated
clockwise in one-turn increments until the problem goes away.
Large tools (such as «” impacts and large pulse tools; generally
those over 100 Nm) may require that the screw be rotated
counter clockwise in one turn increments until proper operation
is obtained.
DO NOT UNSCREW MORE THAN THREE TURNS OUT FROM
THE FACTORY SETTING AS THIS MAY CAUSE THE SCREW
TO COME OUT.
It is important to note that any adjustment to the airflow
screw will require that the set-up be performed from the
first step over again. Do not try to change the setting mid-
set up as this may cause the error proofing to malfunction.
OTHER CONCERNS:
The TC50A is designed to operate with no more than a 25' long,
3/8" max dia air hose. However, the controller will adjust to any
reasonable hose length, provided that the pressure drop and
restrictions don’t affect the airflow volume. With a longer hose
the system will require a longer dwell time between fasteners. If
the time to restart the tool after running down one bolt and
starting the next is too long, shorten the hose. RULE OF
THUMB: the shorter the hose, the shorter the “off / reset” time
between fasteners.
