symbol to indicate the following situations.
The receiver can be operated only with the power voltage of DC18V to 36V specified in this
operating instruction.
Do not drop water or oil on this instrument. Do not use this instrument in an atmosphere of
flammable gas and steam. Use in such an atmosphere may result in fire.
Avoid shock or vibration to this instrument. It may cause a damage or failure.
Before use, make a pre-operation inspection and check the settings.
Be sure to conduct a periodic inspection of torque wrenches.
Use a torque wrench within the measurement range specified in the operating instruction.
Disconnect from power supply if the product needs to be stored for a long period of time.
Avoid using the instrument in a place where there are metal structures around it.

Tohnichi BL series torque wrenches send tightening completion signals by radio waves. The Solar
Panel eliminates need for battery maintenance and costs associated. R-BL receiver models capture
signals from BL wrenches and transfer to external equipment, such as a count checker CNA-4mk3,
Poka-Patrol. The receiver can transfer Completion signals and transmitter serial number to external
equipment. Miss-tightening prevention system can be established with PC or PLC.

6 Precautions for Use
6-1 Solar Cell
Charge the battery before first use and after long periods of nonuse.
BL has available 3000 uses within 8 hours under 500 lux illuminance and 9.6 sec.
communication cycle.
BL can perform 300 uses on a full charge under 0 lux illuminance, No Light Conditions.
A fully charged battery will lose power after approx. 4 days if under no light conditions, 0 lux.
It is recommended to have sufficient light on the line/station to continually recharge the
internal battery cell.
There is no battery level indicator.
Keep the solar panel clean. A dirty panel decreases power generation efficiency.
Do not use a solvent such as paint thinner when you clean up the solar panel.
Recharge to full within 1 and half years even if you do not use BL to prevent the battery from
dying.

6-2 R-BL, Receiver
a Power Source
Use the Receiver R-BLA within the range of DC24V.
Make sure to connect DC24V and GND to respective terminal.
The tightening torque of the terminal block is T=50cN.m.
b Operating environment
Use the device in an environment where no metal structure exits nearby wherever possible.
Do not set the antenna for the receiver close to any metal pole, wire or iron pipe. The BL
receiver antenna is arranged parallel to pipes, the communication status may be worsened.
Do not use the device around welding machines, electric discharge machines or any machine
producing electromagnetic noise such as PC.
c Connection with other equipment
Before wiring, check that the power of the device to be connected with the receiver is in the
OFF position.
Use a solder-less terminal of the size as shown below.
The tightening torque of the terminal block screw is T=50cN.m.

d Connecting “RESET”and “LS IN”
If you would like to connect to the "RESET" and "LS IN" terminal please use a non-contact
voltage switch. Example, LS torque wrench, relay, etc.
Do not feed the external power to input circuit to prevent damage.

Set the load of the contact output within the rated load. Relay output rating: DC30V 1A, AC125V
0.5A. The above rated contact capacity is according to resistance load. Some kinds of loads have a
big difference between the steady-state current and the inrush current. Typical loads and inrush
currents are as follows:
Kind of Load Inrush Current
Resistive Load
1 time as large as the steady-state current
Solenoid Load
10 to 20 times as large as the steady-state current
Motor Load
5 to 10 times as large as the steady-state current
Incahdescent Lamp
10 to 15 times as large as the steady-state current
Mecury Vapor Lamp
About 3 times as large as the steady-state current
Sodium Vapor Lamp
1 to 3 times as large as the steady-state current
Capacitor Load
20 to 40 times as large as the steady-state current
Trans Load
5 to 15 times as large as the steady-state current

f Contact Protection Circuit
When the inductive load is opened or closed, a counter-electromotive voltage is generated
and causes a heavy damage to the contact, resulting in a significant shortening of operating
life. Therefore, a contact protection circuit is required. The examples of contact protection
circuits are as shown in the table below.
AC DC
If this circuit is used for timer
loads, leakage current flowing
through cr cause faulty operation.

The standard c and r are as follows:

r：0.5 to 1(Ω) per contact vaolage
(1V)
The above values vary depending on
the property of load or variations in
relay characteristic. Considering that
the capacitor "c" has the effect of
controlling the discharge when the
contactes are open and the resistor
"r" plays the role fo controlling the
current at the next power-on, check
through experiments is required.
Normally, use a capacitor with a

the power supply voltage is 24 or
48V and to connect between the
contacts when the power supply
voltage is 100 to 200V
