Introduction
Thank you for purchasing the BLOP-STC 3, CLT-70STC 3 screw counter. Prior to use,
please read through this operating manual to enable proper use of the equipment. After use,
keep this manual in a safe place.
■Summary
When tightening screws, it is necessary to verify that the operator has tightened the stipu-
lated number of screws for 1 work piece to prevent forgetting to tighten screws. The Screw
counter has been developed as a power supply unit with a screw counting function to relieve
theburdenonoperators,toimproveoperatingefciencyandtopreventcarelessmistakes.
■Counting function
1. This device can be set to tighten between 1 and 99 screws, depending on the work
piece, and for each screw tightened, the display of the number of screws remaining is
reduced by one.
2. Whenthenalscrewistightened,abuzzersoundstopreventforgettingtotightening
ascrew.Thisalsopermitsconrmationofcompletionofwork.
3. After completion of tightening screw, the display of the number of screws is automati-
cally renewed using an auto reset function, and the electric screwdriver will not oper-
ateuntilthesetsignalforconrmationoftheworkpieceisreceived.
* Screwdriver operation in standby mode can be prevented.
4. Preventscountingofconrmationtighteningandadditionaltightening(tightening
screws a second time).
5. The equipment can be set not to count cases where a screw is not fully seated,
obliquelytightenedorwheretighteningisinsufcient*.
* Depends on type of work being performed.
■Other functions
1. Theexternaldevicecontrolfunctionenablessolenoidvalvecontrolofajigtoxwork
in place, and utilization of a commercially available total counter to count the total
number of work pieces completed.
2. In multiple counter mode using the external connection function, careless mistakes
can be prevented independently of the operator by operating several electric screw-
drivers for different numbers of screws or with different output torques in order of the
work being performed, for example in cell manufacturing, etc.
3. This equipment also has a normal power mode, where the counter function is disabled
and it functions as a normal power supply unit.

■Precautions concerning installation location
●Install a short circuit breaker or safety breaker in conjunction with commercial power
supply.
●Install the equipment where it is not exposed to dust, dirt and pieces of metal.
●Install in a location where it will not come into contact with water and oil.
●Do not place or stack heavy objects on top of this equipment.
●Install this equipment in a stable location that will not cause vibration.
● Forinstallationinahighlocation,xtheequipmentrmlytoexcludetheriskoffalling.
●Do not install near high voltage equipment or in noisy environments.
●Do not make input or output wires longer than necessary, and do not bundle with
power supply wiring. This may cause a malfunction.
■Precautions during use
●Connect the equipment to ground and operate at the rated power supply voltage.
●When connecting loads to the output terminals on the terminal block on the rear panel,
do not exceed the rated load. Exceeding the rated load may cause a failure.
●If an external device connected to the +24V DC output or other input or output termi-
nals on the terminal block on the rear panel is affected by electromagnetic induction
effects, such as a relay or a coil for an electromagnetic valve, use noise countermea-
sures such as diodes for absorbing reverse voltage. If noise countermeasures are not
used, this may be the cause of malfunction or failure.
●Do not connect the +24V DC terminal to any of the output terminals (COMP, VALVE,
BZ, ER BZ) or ground terminals on the terminal block on the rear panel. This con-
nection will cause failure of the unit.
●Do not connect the +24V DC terminal to any of the input terminals (RESET, SET) of
the terminal block on the rear panel. This connection will cause failure of the unit.
●When using the functions of the equipment for external equipment with an external
power supply, make the ground terminals common. If ground terminals are not com-
mon, this may cause malfunction or failure.
●
Do not apply voltage to the input terminals or output terminals. Connection to voltage
may cause a failure.
●
Do not change For/Rev SW while your running the screwdriver by either pressing
Lever SW, for Lever start type, or pushing the screwdriver, for Push start type.
It may cause either wrong count or damage internal SW of screwdriver.
When you change For/Rev SW, stop pressing the Lever or stop pushing the screw-
driver and wait until motor stops.
●Use in a temperature range from 5℃- 40℃and at a humidity of less than 80% (free
from condensation).
●Hold the plug when attaching or removing a power cord or screwdriver cord.
●Do not drag the cords or allow them to come into contact with oil or sharp edges, etc.,
or to come underneath heavy objects. This may cause a break or failure.
●If the electric screwdriver locks up, or if there is an overload, the overload protection
function operates. If the overload protection operates several times, it may be because

the work exceeds the load capability of this equipment or the electric screwdriver. If it
is being used correctly and the overload protection is actuated frequently, immediately
stop use, turn off the main power switch, remove the power supply cord from the outlet
and return the equipment to the supplying dealer.
●If overheating occurs, turn off the main power switch, remove the power supply cord
from the outlet and allow the equipment to cool naturally. After cooling, if the unit over-
heats while being used again, immediately stop use, turn off the main power switch,
remove the power supply cord from the AC outlet and return the equipment to the sup-
plying dealer.
●When tightening screws in plastics and other materials that store static electricity
easily, discharge any static electricity prior to starting work. If static electricity is not
discharged,itmaycauseamalfunctionduetostaticelectricityowingfromthetipof
the bit.
●Do not expose to severe shock such as dropping.
●Do not connect other makers' electric screwdrivers, except for HIOS inc., . This may
cause a failure.
●When equipment will not be used for a long period, turn off the main power switch and
remove the plug from the power outlet.
●Do not disassemble or modify the design of the equipment. This may cause a failure.
In this case, the warranty may be voided and you may not be able to get the equip-
ment repaired.
