SET JOINT TYPE
This selection will be based upon the rate of the joint. If the
fastener is free running and the joint rate is hard (like metal-to-
metal, no washer or gasket or like a spark plug application),
select the HARD setting.
Most pulse tool applications will use the MEDIUM setting unless
the joint is very soft. In this case, either select SOFT or go to
the MANUAL setting option. In MANUAL, the operator will stop
the tool when the socket/fastener has stopped rotating. Select
from the four options by pressing the UP/DWN keys.
NOTE: ALWAYS select the HARD setting for direct drive
tools. This will insure the most favorable shut-off and best
ergonomic condition.
• JOINT TYPE: HARD
This is the default setting. If your results are low in torque when
this setting is used, try the MEDIUM or SOFT setting before
raising the SIG value. In “HARD” the tool will shut-off automati-
cally.
•
JOINT TYPE: MEDIUM
The MEDIUM setting is usually the most common setting for
pulse tools and impact wrenches unless the joint is very soft or
has a long rundown. In this setting, the tool will shut-off auto-
matically.
•
JOINT TYPE: SOFT
Use the “SOFT” setting whenever the joint is too soft for the tool
to reach full torque in the MEDIUM setting. This setting will
automatically shut the tool off.
•
JOINT TYPE: MANUAL
In this setting (with the transducer still on the tool if using one),
run the tool on the application.
In the MANUAL LEARN mode, the operator must stop the
tool manually as soon as the fastener/socket stops turning.
This will set the run time of the cycle.
REFER TO THE PROGRAMMING SEQUENCE CHARTS AT
THE END OF THIS MANUAL FOR ASSISTANCE IN SETUP
– SETTING UP USING THE DIRECT DRIVE (10041)
CODE –
Setting up a controller using the 10041 eprom code is similar to
the MANUAL set-up mode of the pulse tool (10039) code.
Follow the chart at the end of this manual for assistance. The
primary difference is the setting of the proper flow signal when
prompted during the Pset programming sequence.
During the programming step of “CHECK FLOW” the display
will tell you to “RUN FREESPEED.” Simply run the tool in free
speed while adjusting the flow screw (located through the back
cover access hole) to obtain a reading of “GOOD.”
VI. ERROR PROOFING “OK / NOK”
Error proofing
is one of the most important features of the
TC50A
controller. Once an application has been set-up, the
TC50A
will control the torque applied and discern between an
“OK” fastening cycle and the following errors.
•
RE-HIT
A RE-HIT is determined to have occurred whenever the
tool is applied to a pre-tightened fastener. An “NOK” will
be displayed.
•
Cross-thread
Whenever the fastener cross-threads into the hole, this
condition will alarm and display “NOK”
•
Slip-off (or cam out)
If the socket or screwdriver bit slips off of the fastener
head, the controller will stop the cycle and alarm this
condition as an “NOK.”
•
Short cycle (premature cycle abort)
Defined as when the operator stops the cycle prior to
completion of the fastening to final torque. This some-
times occurs when the operator anticipates the end of
cycle and “let’s go” of the throttle trigger prematurely,
before the controller has shut-off the tool.
NOTE: The
TC50A
will ignore free air running of the tool.
This feature insures that only attempts to tighten fasten-
ers are accounted for.
VII. INPUTS / OUTPUTS (I/O)
The
TC50A
I/O terminal strip is located internally on the bottom
of the main board. Certain remote connections are also
accessible via the RJ45 (P3) socket located on the right side of
the controller and can be easily accessed using the ROI device
available from Sioux Tools. Standard I/O is optically isolated and
relay operated using dry contacts; normally open. The I/O must
be powered from a remote source.
Standard
INPUTS
are:
1.
Disable (Part Not-Present)
2.
Batch Clear
Input terminals #3, 4 & 5 are used to select between the
different Parameter Sets according to the following table:
3 on
4 off
5 off
Pset 1

are:

3.
Cycle “OK”
4.

P3 Connector
The RJ 45 connector located toward the middle of the board
opening on the side of the controller is designed to provide
access to the following functions through a Remote Operator
Interface called the “ROI.” (p/n 10140):
•
Cycle reject indicator light
• “UP” button
• “DWN” button
• “OVERRIDE” button
• NOTE: Remote “Batch Reset” is available by holding
the OVERRIDE button for one (1) second, then
pressing the UP button once.
VIII. NETWORKING
The
TC50A
is available with four networking or communication
options.
RS 232 Serial Bus
The serial bus is ported through a DB9 connector located on
the right side of the enclosure. The serial output supports
standard ASCII format and will send out packet information after
each fastening cycle as follows:
06JUN03 12:45:27 PSET:1 TGTQ:035.0 Nm TQ:035.2
Nm COUNT:02/05 OK
EtherNET (TCP/IP)
This optional card is accessed via an RJ45 located on the right
