Installation
◦ Do not install this unit in a place with a lot of dust, dirt,
metal pieces, etc.
◦ Use this unit in the operating environment of
temperatures between 5 to 40 °C and humidity of 80%
or less (no dew condensation).
◦ Do not place heavy objects on top of this unit or stack
them.
◦ Choose a stable location with no vibrations. Especially,
when installing this unit in a high place, x it rmly.
◦ Do not install this unit near high-voltage equipment
or in a noisy environment.
Handling
◦ On any commercial power supply, be sure to install an
earth leakage breaker and a safety breaker.
◦ Connect the earth wire and use this unit with the
specied rated voltage.
◦ The load connected to the output terminal on the
back should not exceed the rated load. Exceeding the
rated load may cause a malfunction.
◦ If external devices connected to the I/O ports on the
back are aected by the electromagnetic induction
load from the relay, solenoid valve coil or others, take
measures against noises by using a diode to absorb
reverse voltage. Otherwise, it may cause a malfunction
and failure.
◦ When the automatic screwdriver is locked or
overloaded, the overload protection works. Please
note that if the overload protection works frequently,
that operation may impose a load larger than the
capability of this unit or the automatic screwdriver.
◦ Even if it is properly used, if the overload protection
works frequently with abnormal events including
heat-up, immediately stop using it, turn o the power,
unplug the power cord, and send it to our service
department for repair.
◦ When you tighten screws of workpieces such as resin
products that are charged with a lot of static
electricity, discharge them before screw tightening. If
the workpieces are not completely discharged, static
electricity may ow into the unit from the tip of the bit
causing malfunctions.
◦ When external equipment is to be used with an
external power supply using the function of this unit,
use the GND as the common terminal.
◦ Failure to do so may cause a malfunction and failure.
◦ Do not apply a voltage to the input side. It may cause
a malfunction.
◦ Do not make the wiring for input / output longer than
necessary.
◦ Note that bundling power cables together may cause
a malfunction.
◦ Do not connect parts other than specied ones to the
connection part of this unit. It may cause a
malfunction.
◦ Do not disassemble or remodel this unit. It may cause
a malfunction.
◦ In that case, we may not be able to accept your claim
for warranty or repair.
◦ Do not cause any strong impacts or vibrations against
this unit.
◦ Do not drag cords and do not allow them to touch oil
or sharp edges, or to be trapped under heavy objects.
◦ When connecting/disconnecting the power cord or
screwdriver cord, always hold the plug.
◦ If it is not used for a long time, turn o the power and
disconnect the power plug from the outlet for safety.
Illustrations
◦ Illustrations used in this manual are those for BLT-
AY-61 unless otherwise specied. However, if models
have dierences, multiple illustrations are also
displayed with the model names such as "BLT-AY-61 /
BLT-AY-71."
Safety Instructions
Please read this instruction manual carefully before use to ensure proper operations.

What Can Be Done with This Unit:
◦ Rotation speed can be switched between high and low, and each speed has 11 steps.
◦ The forward and reverse rotations as well as high speed and low speed rotations of the automatic screwdriver
can be externally controlled.
◦ The FOR input for forward rotation can be switched between pulse/reading (for details, see P.08).
◦Tightening check (impact number) can be set, and torque-up trigger in forward or reverse rotation can be
selected.
Note:
Torque-up for reverse rotation is not available for a standard automatic screwdriver because the one-way
clutch works.
◦ For tightening reverse screws, a special automatic screwdriver for reserve screws is required.
◦A special automatic screwdriver for reverse screws is available as an option. Please contact our distributor.
◦ When using the forward rotation screwdriver for reverse rotation, set the reverse torque-up to U0 or d0 (for
example, when engaging a screw with the bit).
◦ The mode of the signal input can be selected in coordination with the movement of the cam movement when
torque-up is set. Also, torque-up for reverse rotation can be set (in the case where the screwdriver for reverse
screw is used).
Example 1: set to U1 (torque-up trigger: once) to tighten a screw at high speed with one impact
Example 2: set to d3 (torque-down trigger: 3 times) to tighten a screw at low speed with three impacts
◦Overtime protection
This is to protect this unit and the automatic screwdriver. Even if the screwdriver happens to keep rotating, it
can stop automatically, and the buzzer noties it when the overtime protection is set on the controller.
◦Overload protection
This is to protect this unit and the automatic screwdriver. If the screwdriver happens to receive overload, it can
stop automatically and the buzzer or the display noties it.
Note:
If the overload protection works frequently, that operation may impose a load that exceeds the capability of this
unit or the automatic screwdriver.
◦ The built-in buzzer can be switched o. (For details, see P.08.).
◦ The terminal block on the rear panel is detachable, and it is easy to install or replace it.
Note:
◦BLT-AY61 is only for BLF-2000/BLF-5000 and PGF-3000/PGF-5000.
◦BLT-AY71 is only for the BLF-7000 series and PGF-7000.
◦ Please do not connect the screwdriver to any power source other than specified one. Otherwise, it may cause a
malfunction or a problem.

To release this, turn off the power of this unit and wait for one minute before turning it on again.
What does OL mean?
Note:
If the overload protection works frequently, that operation may have been imposing a load
that exceeds the capabilities of this unit or the automatic screwdriver.
Cases of overload
・The screwdriver is misaligned to the screw hole
・No device (such as a damper) to alleviate the shock to the screwdriver is attached
・The interval of screw tightening is too short
・ In case of screws with hexagonal socket holes or screws with hexalobular socket holes; they
are likely to be obliquely tightened
・
In case of tightening a tapping screw with a long neck on a sticky material such as resin material

No. I/O Signal name Description
1 External output FINISH output
The signal is output when screw tightening is completed. It is canceled
when next FOR or REV input comes in or when there is a RESET input.
2 Common COM The signal is common for input and output.
3 External input REV input
The signal is input to make the screwdriver rotate reversely. Reverse
rotation continues as long as there is input.
4 External input 2WS input
The rotation speed of the automatic screwdriver can be switched
between two steps. The speed is LOW as long as there is input.
5 External input RESET input This is used to stop the automatic screwdriver.
6 External input FOR input
This is used to rotate the screwdriver forward.
The start type can be selected either pulse start or reading start.
The switching from one type to another can be done using the DIP SW
built in the board (SW6-2). (For details, see P.08.)
●
Pulse input
The forward rotation starts when a pulse (100mS or larger) is entered as
FOR input.
To stop the rotation, enter a RESET input.
●
Reading input
The forward rotation continues as long as there is a FOR input.
To stop the rotation, either turn o FOR input or enter a RESET input.

Con guration of I/O Circuit
−
+
No.6: FOR input terminal
The input circuit consists of
the photo coupler input.
Drop the input terminal to
the GND level with an open
collector or the like.
When importing the output, do so within the speci ed range.
(Maximum DC 24V 500mA. Be careful not to exceed this maximum
value due to a counter-electromotive force especially when connecting
inductive devices such as a relay. Also, for both input and output,
make the wiring to the connected device as short as possible and take
measures against noises.)
Dry contact is used for
the output circuit.
One side is shared with
GND.

Relation Between the Rotation Number and Torque of the Automatic Screwdriver
Note:
These values are only for reference, and they do not guarantee actual performances.
◦Set the number of rotations to ±10% of a specified value.
◦The number of rotations was measured as free run. The number of rotations varies depending on the load over 27.
◦The number of rotations may fluctuate between forward and reverse rotations.
◦The torque was measured by a combination of our torque meter and Fidaptor.
◦The reference table of output torque is listed in the instruction manual of the automatic screwdriver. Refer to them
at the same time.
◦If the overload protection works, change the rotation setting.
