<Caution>
Do not apply voltage to the output terminals.
For use of external equipment with relays or solenoid valve coils, add a diode, etc., to
absorb reverse voltage.
5. Overload protection function
•
The overload protection unit of this equipment interrupts the output if a high current
causedbyoverload,forexampleduetolockingoftheelectricscrewdriver,owsforlon-
ger than a stipulated period and is intended to protect this unit and the electric screw-
driver.
•
If the overload protection function operates, turn the power off and let the unit rest for
one minute or longer, and then turn the unit back on.
<Caution>
If the overload protection function operates several times, it may be because the work
exceeds the load capability of this equipment or the electric screwdriver.

screw.
•
In this operator's manual "completion of screw tightening" refers to normal tightening
work that is performed for 1 work piece.
7. Electric screwdriver operation control function
•
The counter mode and multiple counter mode for this equipment are functions that
permit or prohibit operation of the electric screwdriver based on a set signal.
8. Counter mode
•
Operating mode where the set number of screws to be tightened is displayed, and this
display is reduced by 1 each time a screw is tightened.
9. Multiple counter mode
•
In addition to the counter mode function, this is an operating mode for using relays for
multiple electric screwdrivers that are set at different torques or use different bits for 1
work piece.
•
Connect an equivalent number of electric screwdrivers and main units using a daisy
chain method. (See Fig. 2, p. 22).
<Caution>
When using an electric screwdriver in its order of operation, the other electric screw-
drivers will not work and their operation is prevented.
