Be certain that the transducer/load cell is rated at 2 Mv/v
and that the full scale rating of the device is sufficient for the
maximum torque output of the tool being used.
III. INSTALLATION & AIR REQUIREMENTS
The controller is designed for mounting to a stable surface or
bracket by bolting it via the four flanged mounting holes. It
should be mounted in a vertical manner and not more than 30
degrees off of vertical. The dimensions for mounting are as
shown in Figure 1.
Air Supply Requirement
In general, the supply line that is sufficient to run the tool being
used is adequate to power the
TC50A
controller. A supply of
compressed air that is filtered and dry is required. For the
TC50A
, a minimum of 90 psi (6.2 Bar) and 50 SCFM (1500
liters/minute) is required for full range operation. However, the
controller will operate below this level with reduced efficiency. If
the air pressure and volume are insufficient, the performance of
the tool will suffer and the full torque range of the tool will not be
realized. If the controller does not receive sufficient air volume,
the tool may operate erratically and the controller will indicate
“NOK” on the display.
The
TC50A
is designed to operate with a maximum air hose
length of 25 feet (7.5 meters) to the tool. The air hose should be
a 3/8" (10 mm) inside diameter with no restrictions (fittings)
smaller than 1/4" inside diameter. Prevent any unnecessary
restrictions, elbows, swivels, etc from being installed between
the controller and the tool.
Install the
TC50A
controller onto an airline with an air filter
before the air inlet to the controller. If an in-line lubricator is
used, it must be installed after the controller between the outlet
and the tool. It must be a free flowing design and not smaller
than 3/8" NPT. Plug the power cord into a grounded outlet.
IV. TOOL COMPATIBILITY
The
TC50A
controller is compatible with all major brands of
industrial pulse tools and direct drive pneumatic tools and is
available to control tools ranging from 1/4" drive to 1" sq drive;
regardless of torque requirement. There are two (2) models
available that cover the full range of tools available; the
TC50A
and the
TC50A-2
H-F (High Flow).
The
TC50A
will flow up to (40) SCFM and will generally operate
pulse tools up to (120) Nm. Tools rated over this level should be
operated using the
TC50A-2
H-F for best results. The
TC50A-2
H-F can handle most if not all pulse tools beyond the capabili-
ties of the
TC50A.
The
TC50A
doesn’t require a shut-off tool, a signal port & signal
tube or even a built-in transducer to control and error proof up
to (8) applications.
Should you desire to control existing tools with the
TC50A
and
the tools are shut-off type, you will first need to adjust the shut-
off mechanism to its maximum setting or otherwise disable it. If
the tool has an internal governor (such as the Cooper/CLECO
brand), you must disable the governor.

SET-UP “MAIN MENU”
The MAIN MENU will appear upon power up of the controller.
There are three functions under the Main Menu. Use the UP/
DOWN key to scroll.
PARAMETER SETUP
Under this selection, the programming of applications takes
place. Refer to the Programming Sequence Chart in the center
of this manual.
TIME/DATE
Using the UP and DOWN arrows as prompted on the display,
set the TIME and DATE to current.
CYCLE COUNT
This feature may be used to signal when maintenance is due.
Using the display prompt, set the cycle count warning monitor
by pressing the “up” or “down” arrow keys. Single keystrokes
will increment the counter by one hundred while holding the key
down will increment in 1000 counts. 500,000 is maximum while
a count of zero disables the alarm. To Clear and reset the
counter, press the down button which will reset the counter to
zero but will not disable the function. Press the reverse/back-up
key to return to the run display.
PROGRAMMING “Pset MENU”
The PROGRAMMING menu is used to set-up a Pset to an
application. By following the display prompts, the user will setup
the system through the defined steps. There are two methods
available to setup a Pset to an application; DYNAMIC or
MANUAL mode. To use DYNAMIC mode, you must have a
transducer connected to the controller of the proper range and
be setting up a pulse tool. MANUAL is used whenever a
transducer isn’t available or for direct drive tool set-up.
ROTARTY TORQUE TRANSDUCERS
The
TC50A
is designed to utilize “Industry Standard” type rotary
torque transducers. The transducer connector port is at the
bottom of the controller next to the air outlet. Many rotary
transducers are not suitable for pulse tools and NONE are
suitable for impact wrenches. Make certain that the range of the
transducer being used is capable of handling the torque output
of the tool being applied and that it is pulse tool rated.
If you should desire to use a Crane Electronics, Ingersoll Rand
or Atlas Copco rotary transducer (auto identification type),
contact your salesman to obtain the proper “WALLABY” (Part
No. 10033) adapter. This will allow use of these common rotary
torque transducers.
Stationary torque transducers may also be used for calibration
and set-up in the MANUAL mode as well as for use with impact
tools.
