PRECAUTIONS FOR PROPER USE

Wiring

•Make sure that the power supply is off while wiring.

•Check all wiring before applying power since incorrect wiring may damage the internal circuit. Also, carefully tighten the terminal screws so that the wires of adjacent terminals do not touch.

•The mounting hole for the terminal cover fixing screws inclines 70 degrees to the terminal cover, as shown in the figure below. To avoid damaging this product or screw, take care when tightening or loosening a screw.

Screw for terminal cover fixing

Screwdriver

•To maintain water-resistance, the cable should have an outer diameter between "9 to "11 mm "0.354 to "0.433 in with a smooth covering material that allows the attached conduit connector to be securely tightened; the tightening torque of the screw should be of 1.5 to 2.0 N
m.

•Verify that the supply voltage variation is within the rating.

•If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.

•In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this sensor, connect the frame ground (F.G.) terminal of the equipment to an actual ground.

•Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.

•If an external surge voltage exceeding 4 kV is impressed (DC- voltage type: 1 kV), the internal circuit will be damaged, and a surge suppressing element should be used.

•Prepare the cable end as shown below.

Gland packing (Note)	Gland	25 mm
		0.984 in

Note: When assembling the conduit connector, pay attention to the direction of the gland packing.

Furthermore, in order to maintain water-resistance, fit the gland packing such that the seating surface of the gland packing contacts the packing holder part of the terminal cover evenly.

•The size of conduit is M201.5.

•If pressure terminals are to be used, affix the connected pressure terminals to a terminal (M3.5 screw).

Part description

Stability indicator (Green)
Distance adjuster (2-turn)	OFF-delay timer adjuster (Note 2)
Adjuster indicator	ON-delay timer adjuster (Note 2)

Operation indicator (Orange)

Operation mode switch (Note 1)

Notes: 1) The operation mode switch of the DC-voltage type is the DIP switch. Refer to ‘DC-voltage type’ of ‘Operation mode switch’ for details.

2) Incorporated on EQ-5Tonly.

Operation mode switch

Multi-voltage type (L-ON / D-ON mode only)

Operation mode switch Description

Detection-ON mode is obtained when the switch is turned fully clockwise (L side).

Detection-OFF mode is obtained when the switch is turned fully counterclockwise (D side).

Note: Turn the operation mode switch gradually and lightly with the attached screwdriver. Turning with excessive strength will cause damage to the adjuster.

Timer mode	OFF		Timer ON
Not used	N.C.		N.C.

BGS / FGS function (DC-voltage type only)

•DC-voltage type sensor incorporates BGS / FGS function. Select either the BGS or FGS function depending on the positions of the background and sensing object.

BGS / FGS function is set with the operation mode switch.

•Depends on a selection of either BGS or FGS function, the out- put operation changes as follows.
