TW-800R-SC/TW-800T■Outline
TW-800R-SC is a receiver with wireless function and a simple counting function.
Receiver[TW-800R-SC] is used one-to-one with various tools equipped with Transmitter[TW-800T].
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.
When receiving a signal from the transmitter, the count will be reduced by one. When the number of tasks
completed reaches a specified number, the remaining tasks are counted as “0”, and the receiver notifies by soundand display and a PASS output is generated.

TW-800R-SC/TW-800T■Installation
Transmitter
Transmitter is used by attaching to various kinds of tools such as torque wrench, plier wrench, check pen, battery
tool etc. As plier wrench and check pen are original products of Herutu Electronics, basically it is shipped withtransmitter attached.
The torque wrench can be attached to the following manufacturer's products.
TOHNICHI Mfg. Co., Ltd.：LS type（QLLS, QSPLS, etc.）
Nakamura Mfg. Co., Ltd.：MBtype（N-SPK-MB, N-QSPK-MB, etc.）
For other tools installation please contact sales department.
<Installation the transmitter to torque wrench>①To install the seatFix 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
betweenWrench shaft and Wrench seat to protect the internal board.
Apply the screw locking agent

×４

onto the 2 to 3 threads of screwedge.

②Fix 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 wrenchin movement.
The hexagon socket head bolt requires a washer.
Apply the screw locking agent on 2 to 3 threads ofhexagon socket head bolt.

Wrench lever

Hook the Transmitter on the Case holder of Seat, set it with an attention being paid not to bite the cord, and fix itwith the set screw as firmly pushing the case.

It hooks on a case fixed nail8

TW-800R-SC/TW-800T<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.
<Installing and removing the battery>●Installing the battery
First, with the “positive (+) terminal” of the coin battery (CR2032) facing up, insert the battery into the gold plated
terminal of the battery holder , as shown in Fig. 1 below.
Push the battery so that it is secured by two catches in the plastic part of the battery holder until the battery snaps
into place.
①②

Gold plated terminal(Notes!)Be sure to insert the battery into the gold
plated terminal first. Inserting the battery into
the plastic part first may damage the gold
plated terminal.

Twocatchesintheplastic part

●Removing the battery
When removing the coin battery for replacement or other reasons, slide a not sharp-edged object between thebattery and battery holder and gently lift the bottom of the battery, as shown in Fig. 1 below. As shown in Fig. 2
below, the battery can be slid out of the battery holder through the tab of the gold –plated terminal.

The battery is slid out of the holder through the tab of
the gold –plated terminal.
①②(Notes!)Care should be taken not to disconnect the limit switch cable of TW-800T while installing or
removing the battery. It is advised to remove the limit switch cable from the connector before
installing or removing the battery.

9TW-800R-SC/TW-800T< Replacing the harness connector with limit switch (TW-800T-HCL) >When replacing the harness connector with limit switch, remove the coin battery and perform the replacement
procedure, as shown below.
①

Pull the cable portion near the connector horizontally to let theconnector mating portion come off from the connector.
(Notes)Remove the cable from the connector carefully. Pulling thecable up may distort the connector mounted on the substrate
and result in damage to the connector.

②
Push the white connector portion of a new harness connector
with limit switch using the tip of the fingernail and insert it into
the TW-800T connector. Push in the connector firmly until it
snaps into place. Make sure the direction of the connector iscorrect before inserting the connector.
(Notes)Do not attempt to apply excessive force to the cable whenconnecting the connector.
Installing the receiver①Install the receiver in a location where it can be seen well from the transmitter and can receive radio waves stably.
②Connect the AC adapter plug to the power jack.
③As necessary, connect a signal line to “Judge output” or “Work-Select input”.
●Judge output(PASS/FAIL output)
The PASS /FAIL output is an open collector output. When the output turns ON, a short circuit occurs between
each terminal.
Be aware that the internal circuit may be damaged when the contact rated load is exceeded.
For use of the Judge output, use the optional output cable for Judge, TW-SC35-3.

TW-800R-SC/TW-800T■Setting/Registering
The transmitter and the receiver need to be paired before use.
By pairing them, they recognize an identification signal from each other and communicate with each other.
Pairing (Registration) - pairing mode
①With the receiver turned off, press the [POWER] key while pressing and holding the [REG.] key of the receiver.
Release the keys shortly after pressing them.
The Receiver LED blinks in green and the receiver enters the pairing mode for 10 seconds.
*Be aware that pressing the [REG.] key too long prevents entry into the pairing mode.

②Long press the pairing switch of the transmitter for 3 seconds or more.
③When the Receiver LED turns off blinking (green) and the receiver enters the count mode, the pairing is completed.
When the Receiver LED stops blinking (green) and lights up (green), this indicates that the pairing has failed. Turn
OFF the receiver power and start the procedure again.

●Reset pairing①With the receiver turned off, Press the [POWER] key while pressing and holding the [REG.] key of the receiver.
Release the [POWER] key only immediately.
②When long pressing the [REG.] key for 2 seconds or more, the Receiver LED stops blinking (green) and lights up(green) and the transmitter registered for pairing is deleted from the receiver.

*When the transmitter is not registered in the receiver, turning ON the power displays “-” instead of a numerical value,
as shown below. (Count mode)◆Notes
●A long press on the pairing switch of transmitter (3 seconds or more) when the receiver is not in the pairing
mode resets the pairing with the receiver and prevents communication with the registered receiver. When pairing
is reset by mistake, perform the pairing procedure again.

The transmitter is equipped with a test switch for communication and battery voltage checks. The Receiver (RX)LED is triggered by a signal from the test switch, but countdown and output is not executed. When the test switch
is pressed, the transmitter checks the battery remaining capacity. The result is indicated by the Transmitter LED
or the Receiver LED.
The test switch also can be used as a pairing switch. A long press on the test switch (3 seconds or more) resets
the pairing with the receiver and prevents communication with the registered receiver. When pairing is reset by
mistake, perform the pairing procedure again.

When the battery is low, the red LED will light for 1 second.
②Battery replacement notice: If the battery level is lower than in ① and the battery needs to be replaced,
the green LED flashing after transmission will change to an orange LED flashing.
When the orange LED blinks, please replace it with a new battery immediately.
When you replace the battery with a new one, the LED on the transmitter will return to green from the secondand subsequent transmissions.
