Trimmer Auto Switch Precautions 1

Be sure to read before handling
Design & Selection

Warning

1. Confirm the specifications.

Read the specifications carefully and use this product appropriately. The product may be damaged or malfunction if it is used outside the range of specifications of current load, voltage, temperature or impact.

2. Take precautions when multiple cylinders are used close together.

When multiple auto switch cylinders are used in close proximity, magnetic field interference may cause the switches to malfunction. Maintain a minimum cylinder separation of 40mm. (When the allowable separation is indicated for each cylinder series, use the specified value.)

3. Keep the wiring as short as possible.

Use a wire 3m or shorter between the sensor and amplifier. Although wire length of power supply/output cable should not affect switch function, use a wire 100m or shorter.

4.Take precautions for the internal voltage drop of the switch.5.Pay attention to leakage current.

Although a varistor for surge protection is connected at the output side of a trimmer auto switch, damage may still occur if the surge is applied repeatedly. When a load, such as a relay, solenoid, which generates surge is directly driven, use a type of switch with a built-in surge absorbing element.

6. Cautions for use in an interlock circuit.

When an auto switch is used for an interlock signal requiring high reliability, devise a double interlock system to avoid trouble by providing a mechanical protection function, or by also using another switch (sensor) together with the trimmer auto switch. Also perform periodic maintenance and confirm proper operation.

7. Ensure sufficient clearance for maintenance activities.

When designing an application, be sure to allow sufficient clearance for maintenance and inspections.

Mounting & Adjustment

Warning

1. Do not drop or bump.

Do not drop, bump or apply excessive impacts (980m/s2 more for sensor unit and 98m/s2 or more for amplifier un while handling.

Although the body of the switch may not be damaged, t inside of the switch could be damaged and cause malfunction.

2. Do not carry a cylinder by the auto switc lead wires.

Never carry a cylinder by its lead wires. This may not on break the lead wires, but it may cause internal elements of t switch to be damaged by the stress.

3. Mount switches using the proper tightenin torque.

When a switch is tightened beyond the range of tighteni torque, the mounting screws, mounting bracket or switch m be damaged. On the other hand, tightening below the ran of tightening torque may allow the switch to slip out position.

Wiring

Warning

1.Avoid repeatedly bending or stretching lea wires.

Broken lead wires will result from applying bending stress stretching forces to the lead wires.

2.Be sure to connect the connector for sens to the amplifier before power is applied.

3.Confirm proper insulation of wiring.

Be certain that there is no faulty wiring insulation (contact w other circuits, ground fault, improper insulation betwe terminals, etc.). Damage may occur due to excess curre flow into a switch.

4.Do not wire with power lines or high voltag lines.

Wire separately from power lines or high voltage line avoiding parallel wiring or wiring in the same conduit w these lines. Control circuits, including auto switches, m malfunction due to noise from these other lines.

5. Do not allow short circuit of loads.

Output is automatically stopped when the protection circuit working, as the output unit registers any excess current flo if loads are short circuited. Should this occur, shut off t power supply, remove the cause of this excess current fl and switch on the power again. Take special care to av reverse wiring between the power supply line (brown) and t output line (black, white).

6. Avoid incorrect wiring.

If the connections are reversed (power supply line + a power supply line –), the switch will be protected by protection circuit. However, if the power supply line (–) connected to the black, white wire, the switch will
