1 Introduction
The TCV/FM Switch Wrench System is designed to assist the manufacturer in closing sev-
eral gaps in the quality system that have hindered their quality improvement efforts. The
key capabilities this system enables are:
1. The ability to integrate manual torque wrenches into the automated line control system.
2. The ability to attain control of the actual torque wrench use process, not just the
wrench calibration process.
3. The ability to provide rapid and effective training in proper torque wrench use through
reinforcement of proper technique with every cycle of the wrench.
1.1 Control Concepts
The TCV works with the FM Switch Wrenches to bring systematized control to the use of
manual torque wrenches. The control is applied as follows:
1. There are three ways to use a clicker-type torque wrench. When used properly, a steadi-
ly increasing force is applied until the wrench clicks and the pressure is immediately
released and the tool resets. One improper use technique consists of applying force too
quickly (”jerking” the wrench). The other improper technique is to continue to apply force
after the click and overtorque the fastener.
2. When the correct technique is used the torque wrench spends a certain amount of time
in the “clicked” position. When the wrench is used too quickly it spends less time in the
clicked position. When it is rotated past the click it spends more time in the clicked posi-
tion.
3. The FM Switch Wrench is a preset clicker-type torque wrench. The torque is preset using
a torque tester to assure the wrench is accurately set. The torque setting is then locked
in.
4. The FM Switch Wrench has a timer that measures the duration of a click (cycle) of the
wrench. once the wrench has been accurately adjusted on the tester, variation in tech-
nique can be controlled by measuring and controlling the duration of the click.
5. An experiment is conducted to determine the correct use of the torque wrench (duration
of time in the clicked position) to obtain the correct torque on the joint. The accurately-
preset torque wrench is used to tighten the fastener(s) on the joint and an indicating
torque wrench is used to check the torque after the tightening. The experiment deter-
mines the minimum and maximum click duration to attain proper torque.
6. The minimum and maximum duration of a proper click is programmed into the TCV.
[Time Minimum or TMIN and Time Maximum of TMAX]

7. In use, the FM Switch Wrench tightens a fastener. As soon as the wrench clicks a timer
on the wrench starts measuring time.
8. When pressure on the wrench is released and the wrench resets, the timer stops and the
duration of the click is transmitted to the TCV. The TCV compares the duration of the
click to the TMIN and TMAX specification limits.
9. The TCV immediately communicates to the operator the acceptability of that use of the
wrench. Light emitting diodes (LED’s) and a buzzer inform the operator whether or not
the wrench was used properly and the click accepted.
10. The TCV also uses the Input/Output Relays to communicate to programmable logic con-
trollers or other peripheral devices the acceptability, or lack of acceptability, of each use
of the wrench.
1.2 Component Nomenclature
1Cabinet
The Cabinet houses all of the electronic components in the unit. On the left and right sides
of the Cabinet there are flanges with holes for mounting the unit to an appropriate support.

lights and
remains lit
when electric
power is sup-
plied to the unit
and the power
switch is in the
“On” position.
4Accept Light Emitting Diode (LED)
The Accept LED emits a green light to notify the operator when a wrench cycle meets the
duration specification.
5Reject Light Emitting Diode (LED)
The Reject LED emits a red light to notify the operator when a wrench cycle has been
rejected.
Page 3
6Strength/Prog Light Emitting Diode (LED)
In normal operation this Light Emitting Diode (LED) will emit green, yellow, or red light. If
the LED is green, the TCV is receiving a strong radio signal from the FM Switch Wrench
that it is working with. If it is yellow the signal strength is marginal. If this LED is red than
the signal strength is inadequate and the distance from the tool to the TCV should be
reduced. During programming this LED will be lit continuously to indicate the unit is in pro-
gramming mode.
7Key Lock
The Key Lock permits and denies access to programming the unit. When
the Key lock is in the PROG position, programming functions are
enabled. When the Key Lock is in the LOCK position, the unit is in the
normal operating mode and only those functions are accessible.

3.2 Mounting the TCV
This unit may be wall mounted, table mounted, beam mounted, suspended overhead,
pedestal mounted, or used without mounting. Mounting tabs are located on flanges on the
rear of the cabinet.
The mounting location should be in a stable, secure area so as to avoid damage to the unit
and avoid injury to the operator due to an inconvenient mounting. Locate the unit so that
ambient air can circulate freely around the cabinet.
This unit should be located to allow access to the front panel and connectors. The location
should allow for unrestricted and comfortable viewing of the front panel. The unit may be
remotely mounted, but should still be accessible.
3.3 Source Power
CAUTION! This unit is capable of being powered by 115 VAC
or 230 VAC (both 50 and 60Hz). Before powering up the
unit for the first time, make sure the voltage selection on
the power entry module matches the type of power being
applied.
1. The voltage setting for the unit is always displayed in a
window above the power switch, shown as #1 in the
image to the right. Always check the voltage for compati-
bility before supplying electric power to the unit. For this
example the voltage will be changed from 115VAC to
230VAC.
2. If the setting needs to be changed because it does not match
the power to be supplied, open the access door marked as #2
in the prior image by prying outward gently with a fingernail or
small screwdriver. Slide the red voltage selector/fuse holder
out of the module.
Page 7
3. Turn the red voltage selector/fuse holder over so the voltage
matching that of the power to be supplied has the top of the printed
voltage facing upwards.
4. Reinsert the red voltage selector/fuse holder into the module.
The face of the voltage selector/fuse holder will be slightly
recessed in the module when it has been properly reinserted.
5. Close the door over the voltage selector/fuse holder. The cor-
rect voltage, that which matches the voltage of the power to be
supplied to the unit, should now show through the window.
The TCV is fused at 1 Amp for 115VAC. The TCV is fused at
1 Amp for 230 VAC. The fuses are located on the sides of the
voltage selector/fuse holder, as shown in the accompanying
photograph.
6. Use the Power Cord to bring electric power from the source to the TCV. Check the Power
Switch and make certain that it is in the “Off” or de-energized position. Connect one end of
the cord to the TCV at the Power Entry Module and plug the other end into the electric
outlet.
3.4 Connecting Peripheral Devices
The TCV has relay outputs and an optically isolated RESET input. All of the relays can be
accessed through the 5-Pin Connector on the bottom of the Cabinet. The TCV also has a
serial port labeled “RS232”. The serial port is used to connect to a personal computer or lap-
top computer running the TCV software to accomplish programming of TCV parameters.
The circuit diagram below is that for the relays.
