■General outline
TW-800 is constituted by a Transmitter[TW-800T] and a Receiver [TW-800R]
Once the TW-800T is mounted on the Torque wrench a tool of others with Limit switch (LS), the tightening
completion signal of Torque wrench can be transmitted to each series of our TWF-800R.
<Feature>
◆Reliable communication
TW-800 can communicate automatically by selecting the channel from 78ch in 2.4GHz bandwidth.
TW-800 transmits the signal reliably by 2way communication.(You can look see the communication OK/NG by
LED lighting and flashing.)
◆TW-800T has the function of remaining battery level notice.(At using test switch)
If remaining battery level is low at using test switch, you can look see the LED situation of TW-800T and
TW-800R.
◆TW-800T uses CR2032 type of battery for small size and light weight.(Size is same as TW-510T)
◆The case of TW-800T is used polypropylene for protecting broken the case.
◆TW-800 uses the communication band which can be used worldwide.
◆TW-800T has test switch for test communication and battery remaining check.
◆It is easy to set the registry of TW-800T and TW-800R.
It is easy to do ”Pairing”with TW-800T and TW-800R.It is not necessary to manage the channel and ID.
◆TW-800R can be set various setting
1.Buzzer: On/Off
2.Buzzer volume:2 kinds Small/Big
3.Output time of Photo-Mos relay: 4kinds 50ms/200ms/400ms/1s
4.Double-count protect time: 4 kinds 10ms/200ms/1s/2s
◆The power source of TW-800R is DC24V.
The power source of TW-800R that is often connected with controlled equipment is DC24V.
It can be used AC100-240V by using AC adapter of option
※For the cause of transmitter ”TW-800T” and receiver “TW-800R” recognize both sides by pairing, equipment
configuration is set to 1to 1.It can’t be used two or more sets of transmitter for one set receiver.

■Installation
<Installation the transmitter to torque wrench>
To install the seat
Fix the Seat with four fixing screws.
For the application with heavy oil mist, fill up the caulking agent between Wrench seat and Seat and also between
Wrench shaft and Wrench seat to protect the internal board.
Fix the Transmitter Limit SW with two hexagon socket head bolts(which was removed).
Verify that the moving range of wrench lever is well suited for the movement range of switch during the wrench
in movement.
Hook the Transmitter on the Case holder of Seat, set it with an attention being paid not to bite the cord, and fix it
with the set screw as firmly pushing the case.
Apply the screw locking agent on 2 to 3 threads of
hexagon socket head bolt.
Wrench lever
Apply the screw locking agent
onto the 2 to 3 threads of screw
edge.
The hexagon socket head bolt requires a washer.
It hooks on a case fixed nail

<The attention and the check method on limit switch attachment>
When the lever working range of a torque wrench is small, a limit switch cannot be struck and a transmitter may
not send. In limit switch attachment, be careful enough and carry out.
<Input Judgment time for transmitter>
Transmitter don’t transmit when the signal from limit switch is within 40ms.
This function prevent transmitting the signal at striking the limit switch when the torque wrench is fallen.
When you install a limit switch and a transmitter, it can not send the signal that you strike a limit switch by your
finger. But it is based on the abovementioned processing.
In the case of tightening the limit switch in normal, the time is approx 100ms-170ms.
In the case of striking the limit switch by being fallen, the time is approx 20-30ms.
Input judgment time of transmitter is set by above cause.
<Installation the receiver>
■Install this machine in the place where it can be easily viewed from the Transmitter and also an electric wave
can be stably received.
■Set the antenna so that it is not parallel to the metal plates and keep away it from metal plates as far as
possible.
■Feed the stable power supply (DC24V) with less variation.
When you use with AC power supply, please use the AC/DC adaptor “ADB24050”of an option.
■Make a wiring for the output terminal block.
Output turns on with relay contact. Once output turns on, short-circuited condition is made between terminals.
Once the rated contact load is exceeded, inner circuit might be damaged. Use an extreme care.
Terminal block:M3(2P)
Input power source:DC24V(DC19～DC28V)
Rated load voltage AC/DC30V per point
Rated load current 0.5A per point
Contact mechanism MOS-FET/1a

The antenna of a receiver should install so that there is no obstacle in the circumference of an antenna.
Receiver has 2 antennas and it is diversity type. Both antennas should install that there is no obstacle in the
circumference of an antenna.
Also in case of setting installation 2 receivers for parallel, it should install separately over 5cm from each antenna
at least.
Antenna should Install 30-45 degree of
the directions of the front.
An antenna is seen from the front, is opened
in the direction of outside 0-45 degree, and is
installed in it.
It should be installed separately over 5 cm at least

・This product serves as a minus (-) ground.
In the case of the place which is fixed this receiver is steel such as an operator control panel and a
pillar of a production line, please fix this receiver after confirming minus grounding or plus
grounding.
Please keep in mind that the short circuit breaker of equipment may operate if it fixes with
equipment of a plus earth accidentally.
When fixed with equipment of a plus earth, I avoid the fixing to a metal thing, or please give me the
disposal of fixing on both sides of an insulator.

■Setting
It needs “pairing” a transmitter and a receiver before using. Transmitter and receiver communicate by recognizing
the other party's recognition signal by pairing.
●Pairing (Registration)
1. Power Switch is turned on pushing the lighting switch for paring of a receiver.
To enter “Pairing mode” only 10 seconds with flashing the lighting switch for pairing.
2. You continue pushing the “pairing switch” over 3secondsof transmitter by a long and slender thing.
3. It is completed the pairing between transmitter and receiver, then the lighting switch of receiver is turned off.
4. It can communicate with transmitter being pairing, you turn off the power switch of receiver once.
●Delete the pairing
1. Power Switch is turned on pushing the lighting switch for paring of a receiver.
To enter “Pairing mode” only 10 seconds with flashing the lighting switch for pairing.
2. You continue pushing the “lighting switch for pairing” over 2 seconds, then the lighting switch is turned on.
The transmitter which is register by pairing is deleted.
◆Caution
Please keep in mind that a transmitter cancels the pairing information (registration information on a receiver)
which was carrying out the memory, and the communication with the receiver which was carrying out pairing
becomes impossible if a receiver carries out the long aggressiveness of the pairing switch of a transmitter 3
seconds or more in the state where it is not in pairing mode.

◆Caution
While the receiver output relay output or while receiver is in double count protect time, receiver transmit the
busy signal to transmitter. Then receiver doesn’t move.
When the transmitter receives the busy signal, the Green LED of transmitter flashes 3 times.
According to setting relay output time and double count protect time, a difference is made for a transmitting
intervals. Please set depend on your situation.

■How to use
1. Power switch of receiver is turned on. Please confirm the LED situation as turning off.
When the LED for receiving turns on, the transmitter is not registered by pairing. Please make a pairing with
transmitter.
2. Transmitter transmits the signal at striking the limit switch by tightening the bolts from torque wrench.
When the communication is done normally, receiver output the relay output and receiver sounds the buzzer
according to setting. Green LED of transmitter turns on 1 time.
When the communication is not done normally, receiver doesn’t move.
While the receiver output relay output or while receiver is in double count protect time, receiver transmit the
busy signal to transmitter. When the transmitter receives the busy signal, the Green LED of transmitter flashes
3 times.
