Introduction
Thank you for purchasing the separate counter series BLOP-SC1 and CLOP-SC1. Please read
through this instruction manual carefully before use for proper operating instructions. Store this
manual in a safe place for future reference.
ŶOutline
The counter function can be added by connecting a HIOS driver power supply to the SC1 Series.
- The BLOP-SC1 can be connected to the T-45BL and T-70BL power supply for brushless drivers.
- The CLOP-SC1 can be connected to the CLT series and MC-70L power supplies.
ŶSC1 Series Count Function
1. The number of screws to be tightened for a particular work piece can be set to between 1 and 99
for this unit. The remaining number of screws to be tightened is counted down in the display after
each screw has been tightened.
2. A buzzer sounds after the final screw has been tightened to prevent the operator from forgetting to
tighten screws. This also allows the operator to check whether work on a particular piece of work
is complete.
3. The auto reset function automatically updates the unit’s display when all screws have been
tightened and can be used to prevent the driver from being used until the SET signal is received
when the next work piece is set.
* The driver cannot be used while in standby mode.
4. Prevents tightening checks and increased tightening (tightening a screw a second time) from being
counted.
5. The unit can be set so that it does not count screws that have not been properly seated and cross-
threaded screws.
* Varies with the type of work being performed.

ŶOther Functions
1. Control of External Equipment
- The number of completed work pieces can be counted by controlling solenoid valves used to
hold the work piece in place or commercially available total counters.
2. Multi-count Mode using the External Connection Function
- Several screwdrivers with differing screw tightening capabilities or output torque may be used in
cell production, with only the appropriate electronic screwdrivers operational in the order they are
to be used. This prevents careless mistakes made by operators.

result in incorrect readings.
ŶPrecautions for Use
ƔGround the HIOS power supply connected to the unit and use the power supply within the
specified rated power and voltage.
ƔEnsure that loads connected to the output terminals on the rear panel terminal block do not
exceed the rated load.
Exceeding the rated load can cause a malfunction.
ƔIf external equipment connected to the +DC 24 V output terminal or input/output terminals on the
rear panel terminal block are affected by the electromagnetic induction of relays and solenoid
valves coils, noise prevention in the form of reverse voltage absorbing diodes should be used.
Equipment may operate incorrectly or malfunction if noise prevention is not used.
ƔDo not connect the +24 V DC terminals on the rear panel terminal block to the GND terminal.
Doing so will result in a malfunction.
ƔDo not connect the +24 V DC terminals on the rear panel terminal block to any output terminal.
Doing so will result in a malfunction.
ƔA common GND terminal should be used if the unit’s functions are used to power external
equipment with an external power supply. Equipment may operate incorrectly or malfunction if a
common GND is not used.
ƔDo not provide additional voltage to the input terminals. Do not provide voltage or current to the
output terminals that exceeds their rated values. Doing so can result in a malfunction.
ƔUse the unit in temperatures of 5°C to 40°C and 80% or less humidity (with no condensation).
ƔAlways hold the plug when connecting or removing the power cord or driver cord.
ƔDo not pull the cords, drag them across oil or sharp edges, or place heavy objects on top of them.
Doing so may result in severed wires or malfunctions.
ƔThe overload protection function of the HIOS power supply connected to the unit will operate if the
driver remains locked or becomes overloaded. Please note that work involving repeated
overloads will increase load over the capacity of the connected HIOS power supply and electronic
driver. If the unit malfunctions with repeated overloads during normal operations, immediately stop
using the unit, turn off the main power switch of the HIOS power supply connected to the unit,
remove the power cord from the power outlet and bring the unit to our service department.
ƔIf the unit overheats, turn off the main power switch of the connected HIOS power supply, remove
the power cord from the power outlet and let the unit cool down. The unit may be used again once
it has cooled down. If it overheats again immediately stop using the unit, turn off the main power
switch, remove the power cord from the power outlet and bring the unit to our service department.
ƔWhen tightening screws on plastic work pieces that may have a lot of static electricity buildup,

4
remove electricity before starting work. If electricity is not removed, static electricity may flow from
the end of bit, resulting in incorrect operation.
ƔDo not drop or subject the unit to strong shocks.
ƔDo not connect drivers other than those manufactured by HIOS. Doing so will result in a
malfunction.
ƔTurn the main power switch of the HIOS power supply OFF if the unit is not used for a prolonged
period of time, and remove the power plug.

ŶMain Functions and Terminology
1. Tightening Check
- Refers to the act of tightening screws a second or third time to check that the screws have been
tightened properly or to completely seat a screw. The terms second tightening or increased
tightening may also be used for the same meaning.
2. Torque Up
- After each screw has been tightened, the torque is increased to the set level before the electronic
driver clutch is disengaged.
- The unit will recognize the first torque up operation after the normal rotation* count timer elapses
as the final torque up for screw tightening. Please set the count timer so that it does not count
down after torque up operations for tightening checks.
* The normal rotation count timer is hereinafter referred to as the count timer.
3. Signal Input Method
- A photocoupler is used as the signal input method. The input current is a maximum of 10 mA or
less.
- If an open collector connection is used, connect collectors to each input terminal and the emitter
to the GND terminal.


<Caution>
- Do not provide additional voltage to the input terminals.
Use input resistance of 10 ȍor less.
- Add a reverse voltage absorbing diode to the input contact point relay coil.
- Use noise prevention measures when using external equipment (refer to Image 1).
4. Signal Output Method
- The output signal method is open collector output with a maximum rated load of DC 30 V/80 mA.

<Caution>
- Do not provide addition voltage to the output terminals.
- Add a reverse voltage absorbing diode to the coil if a relay or solenoid valve is used.
5. BL-OPC Specifications (electronic driver)
- BL-OPC specifications refer to BL (brushless) electronic drivers with output functions that have
normal rotation, reverse rotation and torque up signal output functions.
6. Screw Tightening Over and Screw Tightening Complete
- Screw tightening over in the instruction manual refers to when one screw has been tightened
completely.
- Screw tightening complete in the instruction manual is when all screw tightening operations for a
certain work piece have been completed.
7. Electronic Driver Operating Control
- The counter mode and multi-counter mode of this unit allows or prohibits electronic driver
operation with the SET signal.
8. Counter Mode
- The number of screws to be tightened can be seen in the count down display as each screw is
tightened.

6) COUNTER OFF (stops all counter functions: only available for the power supply)
Note) reverse rotation count timer (enabled only with the BL-OPC driver)
- The reverse rotation count timer is a timer to set the reverse rotation count up determination time.
- The unit recognizes that a screw has been loosened only when the electronic driver is in reverse
rotation longer than the time set with the reverse rotation count timer, and counts up the number of
screws in the counter display.
Note)
- The unit will count up reverse rotations made when the final screw tightening count is “00”,
regardless of the reverse rotation count timer setting, as even a brief reverse rotation will be
recognized by the unit as loosening a screw.
- The reverse rotation count is a function designed to cancel a screw count resulting from a torque
up operation. After the count has been reversed following a reverse rotation, it will not be possible
to reverse the screw count again until the count down is resumed following normal rotation.

ŶSC1 Series Outline of Basic Operations
* The timing chart on the previous page outlines the basic function of the count mode based on the
premise that the electronic driver torque has been adjusted, default settings made and the number
of screws to be tightened has been entered into the screw counter.
1. TM-1 Timing Chart (when tightening screws up until the last screw to be tightened)
(1) Power “ON”
(2) Set the work piece and input the SET signal.
- The unit is designed to operate normally even if the SET signal changes from ON to OFF while
the work set timer is operational, or if the signal remains OFF even after time set on the work set
timer has elapsed.
(3) Work set timer operation starts.
(4) Work set is released and locked again.
(5) Work set timer operation complete.
(6) Red DRV LED on the front panel will light up allowing use of the electronic diver.
(7) VALVE signal output starts.
(8) Set start lever on the electronic driver to “MANUAL ON”.
(9) Electronic driver operation starts.
(10) Count timer operation starts.
(11) Count timer operation complete.
(12) Torque up after screws have been tightened.
(13) Electronic driver operation stops.
(14) Count down starts using the set number of screws to be tightened. The number on the unit
display LED decreases one by one.
(15) Set start lever on the electronic driver to “MANUAL OFF”.
(16) Set start lever on the electronic driver to “MANUAL ON” for tightening checks.
(17) Electronic driver operation starts.
(18) Count timer operation starts.
(19) Immediate torque up for tightening checks.
(20) Count timer is reset during torque up operation.
(21) No count down due to torque up during count timer operation.
(22) Electronic driver operation stops.
(23) Set start lever on the electronic driver to “MANUAL OFF”.
2. TM-2 Timing Chart (when loosening screws)
(1) Set the FOR/REV switch to reverse rotation.
(2) Set start lever on the electronic driver to “MANUAL ON”.
(3) Electronic driver reverse rotation operation starts.
(4) Reverse rotation count timer operation starts.
(5) Reverse rotation count timer complete.
(6) Count up starts using the set number of screws to be tightened. The number on the unit display
LED increases one by one.
(7) Set start lever on the electronic driver to “MANUAL OFF”.
(8) Electronic driver reverse rotation operation stops.
(9) Set the FOR/REV switch to reverse rotation.

<Caution>
- The unit recognizes that a screw has been loosened only when the electronic driver is in reverse
rotation longer than the time set on the reverse rotation count timer, and counts up the number of
screws in the counter display.
- Please note that count up is not carried out if the start lever is released within the time set on the
reverse rotation count timer or reverse rotation is turned “ON” and “OFF” repeatedly when screws
are being loosened.
- One count up will occur directly after each count down when put into reverse.
- There will be no count up when no screws have been tightened before the driver is put into
reverse rotation in order to loosen a screw.
3. TM-3 Timing Chart (when tightening the final screw)
(1) Set start lever on the electronic driver to “MANUAL ON”.
(2) Electronic driver operation starts.
(3) Count timer operation starts.
(4) Count timer operation complete.
(5) Torque up after screws have been tightened.
(6) Electronic driver operation stops.
(7) Count down starts using the set number of screws to be tightened. The number on the unit
display LED is “00”.
(8) Work reset timer operation starts.
(9) Work completion buzzer starts.
(10) Work reset timer operation complete.
(11) Work completion buzzer stops.
(12) Display LED turns green and electronic driver operation is disenabled.
(13) VALVE signal output stopped.
(14) COMP signal output starts.
(15) COMP signal output stops after 0.1 seconds.
(16) Set start lever on the electronic driver to “MANUAL OFF”.
(17) Release the work piece to stop SET signal.
<Caution>
- In order to enable use of the electronic driver when the first valid SET signal is received, the
position of the SET signal (ON, OFF) during work set timer operations will not effect the ER BZ
signal.
- The ER BZ signal is only output after the time set on the work set timer has elapsed and if the SET
signal changes from ON ĺOFF.
* Operations after screw tightening is complete
The count is reset with the auto reset function once the last screw has been tightened and the
driver will go into standby mode until the next SET signal is received.
(
The electronic driver cannot be used while in standb
y
mode.
)
* Please note that even if screws are not loosened, the unit will count up if the electronic driver is
operated in reverse rotation. This is because there is no torque up signal in reverse rotation.
