3 BLF-2000 BLF-5000 BLT-AY-61 BLF-7000 Series BLT-AY-71 Introduction Thank you for purchasing the BLT-AY-61 and BLT-AY-71 Driver controller. Please read this instruction manual thoroughly before use to ensure proper operation. Store this instruction manual in a safe place for future reference. BLT-AY-71 is only up to 120V ac for warranty more then 120V ac, HIOS can not take any responsibility. -3-

4 Outline Conventional automatic screw drivers of CLF Series, αf Series, and CL-A Series use motors with carbon brushes that require periodic replacement. Wear in the carbon brushes as well as in the commentator affects the operating life of the driver, requiring the motor to be replaced periodically. The BLT-AY-61 and BLT-AY-71 Driver controller uses a brushless motor and not use consumable parts such as carbon brush. That saves much of maintenance efforts for this driver. Features such as 2WS* (2-way speed) and REV (reverse rotation), which are available as optional for CLT-AY-61/CLT-AY-81, are now included as standard. A torque protection circuit is used during low speed 2WS operation to vastly improve bit stopping when re-tightening screws. There is a main power switch, and the primary input voltage ranges from 100 V to 240 V allowing worldwide use. * With conventional Driver controller CLT-AY-61/CLT-AY-81, similar function is called "2WV", but with these new automatic drivers, it is called "2WS". <Notes> 1 BLT-AY-61 is a power supply dedicated to BLF-2000 and BLF BLT-AY-71 is a power supply dedicated to BLF-7000 series. Up to 120V ac only. 3 Any other power supply or counter, such as T-70BL or BLOP-STC3, cannot be used for automatic screwdrivers. Such misuse might cause an accident or other problem. (Notice) We can specially provide you with a screwdriver for left-handed threads on request

5 Precautions Please read this instruction manual thoroughly before use to ensure proper operation. On any commercial power source, install a ground-fault interrupt breaker and safety circuit breaker. Connect the unit to ground and use only the rated voltage. Do not exceed the rated loads for the output connections on the rear panel. Exceeding the rated load will cause the unit to malfunction. If the unit may be subjected to inductive loads from a relay or solenoid valve coil in auxiliary equipment connected to the input/output connections on the rear panel, install a reverse polarity diode to suppress electrical noise. The unit may malfunction if noise suppression is not installed. The overload protection will be activated when the driver is locked or has become overloaded. If the driver is overloaded repeatedly, the maximum ratings of the unit or attached electric driver may be exceeded. If the driver becomes overloaded during Forward operation or begins to malfunction due to developing excessive heat, stop the ongoing operation immediately, turn the main power switch off, remove the power cable, and contact our service department for repairs. When tightening screws on work pieces constructed of plastics susceptible to static electricity build-up, tightening should be performed after static electricity has been discharged. If working on pieces that have not been properly discharged, static electricity may flow up through the end of the bit, causing malfunctions. A common GND should be used if the unit is connected to auxiliary equipment that is powered separately. The unit may malfunction if a common GND is not used. Do not apply voltage to the inputs or outputs. This may cause malfunctions. Extending input/output connection cables longer than necessary or bundling power cables together can cause malfunctions. Choose an installation area with no vibrations. If the unit is installed in a high location, ensure that it is properly secured. Do not install the unit near high voltage equipment or in an electrically noisy environment. Do not place heavy items on top of the unit, or stack the units on top of one another. Do not install the unit in an area where it may be subjected to dust or metal fragments. Do not use the unit with anything other than HIOS drivers as this will cause the unit to malfunction. Do not disassemble or modify the unit in any way, as doing so may cause the unit to malfunction. Such malfunctions are not covered by the HIOS warranty and repairs to the unit may be refused. The operating environment for the driver should be between 5 C and 40 C with relative humidity of 80% or less (there should be no possibility of condensation). Do not drop the unit or subject it to mechanical shocks. Always hold the plug when inserting or removing power cables or driver cords into or from sockets. Do not drag cords or cables, subject them to oil or to sharp edges, or place them under heavy objects. If the unit will not be used for a long period of time, turn the main power switch OFF and unplug it from the service outlet

8 Main Functions 1. The motor control circuitry is incorporated into the BLT-AY-61/ BLT-AY-71, giving the driver a simpler construction. 2. The internal buzzer can be turned off (internal SW 6-1). 3. The FOR input for forward rotation from an external source can be switched between pulse and reading (internal SW 6-2). 4. Forward / Reverse driver rotation High speed / low speed driver rotation can be controlled externally. 5. The rpm can be set in 11 steps comprising for high speed, and 11 steps comprising 5 15 for low speed. 6. The shape of the input signal can be selected to suit the movement of the cam during torque up operations. Torque up can also be set for reverse rotation (for tightening counter screws). Eg 1: Set to U1 when tightening with high rpm and one impact (one UP trigger edge) Eg 2: Set to d3 when tightening with low rpm and three impacts (three DOWN trigger) 7. If the driver keeps rotating and the overtime setting is set on the controller, the driver will stop automatically and a buzzer will sound (recovery by turning power OFF / ON). 8. If the driver is overloaded, the overload protection circuit will be activated, the driver will stop and a buzzer will sound (recovery by turning power OFF / ON). 9. Operation display indicators are installed on the front panel to monitor driver operation. 10. Simple settings are available with the combination of four buttons (Mode,, and ENT) and the 2-digit seven segment display. 11. The internal power supply has a power selector switch and can be used with voltages of any country. 12. The power unit has been made compact and lighter compared to other power units for automatic drivers. 13. The rear terminal block is removable, making installation and replacement simple

9 Main Terminology 1. Tightening Check (setting the impact number) To check that the screw has been tightened properly or to tighten the screw further, the screw is tightened two or three times after the initial tightening. A tightening check can also be referred to as a second tightening or re-tightening. 2. Torque Up After the screw has been tightened and the tightening torque reaches the set torque, the electric driver clutch disengages. 3. UP Trigger Used when the clutch signal is received on the upslope of the cam when the bit is rotating at high speed. 4. DOWN Trigger Used when the clutch signal is received on the down slope of the cam when the bit is rotating at low speed. 5. Input Method Signal input to the unit is through a photo coupler with a maximum current of 10 ma. If an open collector connection is used, connect the emitter to GND and the input to the collector. (Caution) Do not apply any voltage to the inputs. Install a diode that absorbs reverse voltages to the relay coil on the input connections. If any auxiliary equipment is used, include electrical noise suppression. 6. Output Method The output signal of the unit is through a dry contact output internal common GND on one side with a maximum rated load of DC 24 V / 500 ma. A common GND for connections with auxiliary equipment should be used. (Caution) Do not apply voltage to the inputs. Install a diode that absorbs reverse voltages to the relay coil on the input connections. If an auxiliary unit is used, carry out electrical noise suppression. 7. Overload Protection The overload protection circuit stops output to protect the unit and electric driver from excess current if the driver is operated into overload. The overload protection is activated, turn off the control unit and let it sit idle for at least one minute. The driver may be operated after turning the unit back on. (Caution) Please note that if the driver is repeatedly overloaded, activating overload protection, the current rating of the unit or the electric driver may be exceeded

Main SW External I/O terminal Terminal block connector on the main body Model number: XW4A-10B1-V1 Inlet with Fuse Holder 3 A / 250 V Accessories: Power supply side Terminal block connector No Input / Output Signal Name Outline 1 External Output FINISH Output 2 Common COM 3 External Input REV Input 4 External Input 2WS Input 5 External Input RESET Input 6 External Input FOR Input Output is present on this terminal when screw tightening is complete. Output ceases when either the next FOR or REV input is received or when the RESET input is used. Common for input and output. This is connected to the internal controller GND. Apply input to this terminal when you wish to operate the driver in reverse rotation. The driver will operate in reverse while the signal is present. Driver rotation SPEED can switch between two stages. 2WS will be the side while the signal is ON. Used when the driver operation is to be stopped by an external source. Apply input to this terminal when you wish to operate the driver in forward rotation. The method can be selected between pulse and reading. * 1 *1 When the input method is set to pulse, the driver will operate in forward rotation when a FOR input pulse of 100 ms or more is received. To stop rotation, apply input to the RESET terminal. The reading input for the start method means that the driver rotates FOR while FOR is input. To stop the rotation, turn the FOR input OFF or use the RESET input. Pulse or reading can be switched with the DIP SW on the internal board

16 Torque Up Settings Most customers are undoubtedly experienced in driving a car, and are aware that cars traveling up a slope at a high speed will end up going over the mountain even when the brakes are applied, while cars traveling at a low speed will come to a stop before reaching the top of the mountain when the brakes are applied. The automatic brushless screwdriver BLF-series uses a system that traverses the lobe of a mechanical cam to apply torque to screws. To ensure that torque is applied to the bit accurately, a clutch is used when traversing the cam. The timing of the application of the brake when the bit is rotating at high speeds and low speeds is required to be adjusted to traverse the lobe of the cam. The BLT-AY-61/BLT-AY-71 controller is designed to control the rotational speed of the driver over a large range of speeds from low to high, as well as to allow settings for torque up with DOWN trigger at low speeds and UP trigger at high speeds. Applying the brakes here at a high speed will result in the car stopping past the top of the mountain. The brakes are applied at a low speed here

17 Clutch Mechanism The clutch mechanism is described below. 1 Torque adjustment pressure Detection SW "OFF" Diagram of the mechanism that allows the driver to detect torque. Roller Movement to traverse cam Cam 2 Torque adjustment pressure Roller Detection SW "ON" Cam Movement to traverse cam If the speed when traversing the cam is high, the detection SW turns ON (before traversing the cam) and the brake is applied to the motor. 3 Torque adjustment pressure Detection SW "ON" Roller Movement to traverse cam If the speed when traversing the cam is low, the detection SW turns OFF (after traversing the cam) and the brake is applied to the motor. Cam 4 Detection SW "ON" Torque adjustment pressure By traversing the cam, torque is transferred accurately and the screw is completely tightened. Cam Roller Movement to traverse cam
