4 Tool Communications
Each TCV unit can work with one SLTC-FM 2.4 GHz preset torque wrench at a time. The unit
and tool each use the identitfication number of the transceiver in the other to assure that
there is no crosstalk or erroneous reporting during radio communications.
For the association of individual tool and individual TCV unit to exist, the tool and the TCV
must learn each other's identities before the system can be used.
Since the TCV can only work with one torque wrench at a time, if a tool has already been
learned by the unit the memory of that tool must be cleared should it become necessary for it
to be used with a different wrench.
Both the memory clearing procedure and the learning procedure are given here. There are
several items that should be taken care of before engaging in the procedures.
1. It is usually advisable to preset the torque on the SLTC_FM 2.4 GHz torque wrench before
starting the learning procedure. While the tool can be removed from the vicinity of the TCV
for calibration or unlearned before calibration and relearned after, it is often easier to pre-
set the tool before starting the procedure.
2. Make sure that a battery of sufficient charge is installed in the tool before beginning the
learning procedure. Insufficient battery charge for tool communications can cause confus-
tion and difficulty.
3. Insure that no other TCV unit is undergoing this process at the same time. If two TCV's
and two wrenches must undergo the process, perform the process on one unit and do not
start the process on the second unit until the process is complete on the first unit.
Clearing the Tool Memory
To remove the identification of the TV unit from the tool memory, click the wrench and hold it
in the clicked position until the LED on the wrench flashes. This will take about 5 seconds.
Release the pressure on the tool and allow it to return to the normal position.
The flashing of the LED occurs when the memory of which TCV unit the tool was associated
with has been erased. The tool is now ready to be associated with another TCV unit.
Note that when the battery has been removed and replaced in the wrench the LED will alter-
nate between emitting red and green light several times very quickly. If the alternating color
emission stops and then a red light pulse is emitted, the tool is not associated with a specific
TCV and can be associated with whatever unit is desired. If the alternating color emission
stops and then a green light pulse is emitted, the tool has a specific TCV unit in memory and
is ready to be used with that unit.
