What Can Be Done With This Unit - HIOS BLT-AY-71 Instruction Manual

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).
◦ T ightening 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

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 notifies 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
