(4) Turn on the power of the power supply for BL.
(5) The OPC signal is output from the CN3 connector according to the operation of the BL-OPC
screwdriver.

4. OPC Signal Output Specifications

For the OPC signal output specifications, refer to Table 1. For the timing chart of the OPC signal output,
refer to Figure 3.
*Do not use the device with any current exceeding the ratings of +30V and 10mA for each OPC signaloutput pin.

In addition, to facilitate the use of the OPC signal by external devices, the device converts the +30V,
which is the rated voltage of BL series screwdrivers, to +24V by using a regulator and outputs it to theCN3 connector, the same output location as the OPC signal.

(2) Do not directly connect the +24V pin of the CN3 connector or the external +24V power supply tothe OPC signal pins of the CN3 connector.
(3) Set the speed selector switch of the power supply for BL to HI.If it is used at LOW, the output
voltage of the +24V pin of the CN3 connector decreases accordingly, resulting in a malfunction.
(one-shot output)→ FOR signal output +24V.

2. Screwdriver Reverse Rotation Operation(1) Start lever ON.
→ REV signal output 0V.
(Screwdriver reverse rotation)• Because there is no torque up during reverse rotation,
the T-UP signal is turned off and the output becomes +24V.
→ REV signal output +24V.
(Screwdriver stop)

HIOS Inc.

The BLOP-AF Relay Box has been developed to easily extract the OPC signals that indicate theforward rotation, reverse rotation, and torque up of a BL-OPC screwdriver to allow other external
devices to make use of the signals.

(1) Correctly connect the BL-OPC screwdriver and the power supply for BL to the specified connectorsof the device.Wrong connection may result in malfunction or breakdown.

(2) Screwdriver torque up.
→ T-UP signal output 0V, output for• T-UP signal is output upon
50ms.

1. Overview of the Device

Be aware that using the device without following these instructions may result in a malfunction of orbreakdown with the device and its power supply and screwdriver.

1. Screwdriver Forward Rotation Operation and Torque up
Operation(1) Start lever ON.
→ FOR signal output 0V.
(Screwdriver forward rotation)(3) Start lever OFF.

TEL: +81 (JAPAN) 47-392-2001 FAX: +81 (JAPAN) 47-392-7773(4) Do not overload to the BL-OPC screwdriver. If the +30V voltage of the power supply for BL
decreases to +25V or lower due to overloading, the voltage at the +24V pin of the CN3 connector
decreases accordingly, resulting in a malfunction.
(5) If an external device requires a constant voltage of +24V without being affected by overloading,prepare a separate external power supply for the external output circuit.
(6) Do not use the +24V output of the CN3 connector for any purpose other than for the OPC signal.
Otherwise, overcurrent will flow through the internal circuit of the BL-OPC screwdriver, resulting ina breakdown. Other unspecified usage will affect the screwdriver’s tightening performance or resultin a malfunction or breakdown.
(7) Avoid any usage in which the ratings of +30V and 10mA will be exceeded for each OPC signal pinof the CN3 connector. Overcurrent will result in a malfunction of or breakdown with the device andthe BL-OPC screwdriver.
(8) Do not directly connect external devices in which noise may occur, such as relays, motors, buzzers,
and lamps, to the OPC signal pins of the CN3 connector. Drive noise or overcurrent from external
devices will result in a malfunction of or breakdown with the device and the BL-OPC screwdriver.
If external devices in which noise may occur need to be connected, mount noise suppression
components such as photo couplers and diodes with reference to Examples 5 and 6 in Figure 2,
and carefully confirm the effectiveness before use.

3. How to Use the Device(1) Connect the device with the BL-OPC screwdriver and the power supply for BL using a screwdrivercord, as shown in Figure 1.
(2) Connect external devices to the CN3 connector of the device.
(3) Set the speed selector switch of the power supply for BL to HI.
