Many events in the operating environment may affect the tightening process and shall require a validation
of results. In compliance with applicable standards and/or regulations, we hereby require you to check the
installed torque and rotational direction after any event that can influence the tightening result. Examples
of such events include but are not limited to:
■initial installation of the tooling system
■change of part batch, bolt, screw batch, tool, software, configuration or environment
■change of air- or electrical connections
■change in line ergonomics, process, quality procedures or practices
■changing of operator
■any other change that influences the result of the tightening process
The check should:
■Ensure that the joint conditions have not changed due to events of influence.
■Be done after initial installation, maintenance or repair of the equipment.
■Occur at least once per shift or at another suitable frequency.

Functions
■Driving system: Connect an EBL screwdriver with soft-start function (“ST”) to the EBL ST Controller.
The controller will send the appropriate signals to the screwdriver and thereby regulate the speed
during start-up and also the maximum speed.
■Speed setting system:
EBL12-ST: 320 RPM ±20%(LOW) 910 RPM ±20%(HIGH)
EBL25-ST: 250 RPM ±20%(LOW) 930 RPM ±20%(HIGH)
EBL35-ST: 180 RPM ±20%(LOW) 700 RPM ±20%(HIGH)
■Soft Timer setting system: Adjust the low start speed using the soft-start timer function.
(-) position: 0 seconds
(+) position: more than 3 seconds
■Torque setting system: Adjust the torque using the Torque adjustment key included with the tool.
EBL 12 ST: 0.2 Nm (MIN) - 1.2 Nm (MAX)
EBL 25 ST: 1.0 Nm (MIN) - 2.5 Nm (MAX)
EBL 35 ST: 1.0 Nm (MIN) - 3.5 Nm (MAX)
A LOW rotation setting with maximum, or just below maximum torque could result in a poor result.
Use HI-setting when utilizing a high torque setting if possible.
The maximum speed depends on the setting of either EBL Drive or EBL Drive Plus. If the setting is
LOW, the maximum is 70%.
The ST function is only valid for Forward Rotation. The speed of Reverse Rotation is fixed to the
maximum speed of EBL screwdriver.

EBL12-LS/EBL12-LS-RE: 320 RPM ±10%(LOW) 910 RPM ±10%(HIGH)
■Torque setting system: Adjust the torque using the torque adjustment key included with the tool.
EBL03-LS/EBL03-LS-RE: 0.05 Nm (MIN) - 0.3 Nm (MAX)
EBL03-Q-LS/EBL03-Q-LS-RE: 0.05 Nm (MIN) - 0.3 Nm (MAX)
EBL12-LS/EBL12-LS-RE: 0.2 Nm (MIN) - 1.2 Nm (MAX)
A LOW rotation setting with maximum, or just below maximum torque could result in a poor result. If
there is a need to set the maximum torque with LOW rotation, please adjust the speed of the screw-
driver at the speed which maximum torque setting is available at SPEED VR.
The LS function is only valid for Forward Rotation. The speed of Reverse Rotation is the same as
the setting of EBL Drive, EBL Drive Plus or EBL RE-Drive.
Connectors/Display
1. Connector to be plugged into RE cable from EBL-RE-LS tools.
2. Connector to be plugged into EBL LS tool through 6pins driver table.
3. Not used.
4. Screwdriver speed adjustment during in the sfit timer. If you make a turn to the direction of the arrow
(+), the rotation speed of the screwdriver will increase. Turning to the direction of the arrow (-) in-
creases the speed of the screwdriver.
5. Cable that connects with EBL drive.

EBL RE-Drive and EBL RE Module
Introduction
The EBL RE-DRIVE and EBL RE Module screw counters are used to run and monitor work with EBL
screwdrivers and allow for excellent repeatability and a steady quality level.
Main functions:
■Keep track of the number of screws tightened and allow verification of completion of work.
■Distinguish between a OK tightening and a re-hit tightening.
■Verify minimum time span for each tightening, as well as for time span per work piece.
■Control external devices, such as total counters or jigs for fixing work pieces in place.
The EBL RE-DRIVE can drive a screwdriver directly. The EBL RE Module connects to a separate Drive.

3 Reset Switch Reset the counter functions, inter-
rupts output of the valve signal and
releases the work piece held by an
external device. If operated during
or after setting the set switch, the
display returns to the number that
was set. Performs the same func-
tion as the reset on the terminal
block on the rear panel.

Input Signals (SET, RESET)
The input method for the input signals of this equipment is a photo coupler input. The maximum input cur-
rent is 10 mA. To detect, input a minimum of 2 mA is required.
When connecting an open collector, connect the collector to the input terminal and the emitter to the +D-
C24V terminal.
Output Signals (COMP, VALVE, BZ, ER BZ)
The output signal type of this equipment is an open collector output.
The maximum rated load for each output terminal is 30V DC/80 mA. The maximum total current for
all output terminals is 200 mA. If this limit is exceeded damages to transistors can cause loss of com-
munication with PLC/FA computer.
If an output terminal is short circuited to 0V DC the maximum current is exceeded.
Do not apply voltage to the output terminals. For use of external equipment with relays or solenoid
valve coils, add a diode or equivalent to absorb reverse voltage.
