Safety Key Selector Switch

A22TK

Key-type Selector Switch with Direct

Opening Mechanism

• Selector Switch for secure equipment activation during

maintenance

• 30 types of exclusive keys make it more difficult to disable.

• The key has the same shape as the following keys.

- The key of the A22LK Guard Lock Safety Key Selector Switch

- The trapped key of the D4JL Guard Lock Safety-door Switch

-The lockout key of the D4JL-NSK10-LK and D4GL-SK10-LK Slide Key

Units

• Common to the switch part of Emergency Stop Switch A22E.

(Non-lighted model only)

Features

Because the A22TK Safety Key Selector Switch uses the same key as the Guard Lock Safety-door Switch, the operator is prevented from forgetting

to remove the key. The result is a safer working environment when performing maintenance.

Be sure to read the "Safety Precautions" on page 12.

For the most recent information on models that have been certified for

safety standards, refer to your OMRON website.

Broad range of applications include use with door locks, mode switching, and emergency stops when teaching

Common Key for Door Switch and Selector Switch

With the Selector Switch, it is possible to

switch between normal operation mode

(use of Door Switch is available) and

maintenance mode (use of Enabling

Grip Switch is available).

Safety can be ensured, but there is a risk of human error

occurring during operation.

By using a common key, the risk of human error is reduced in operations

from when the door is open/shut until the equipment is started.

From

When only the Door Switch is used, the operator is at risk of being

shut inside the barrier if, for example, he/she forgets to remove the

trapped key and a third party locks the door.

The equipment may also be started up while the operator is inside.

The two locks on the door and equipment use the same key, reducing the likelihood that the user will forget to remove it.

In addition, the key cannot be removed when maintenance is being performed. This prevents the key from being lost and greatly

reduces the risk of an operator becoming trapped inside.

The safety level is enhanced by switching to maintenance mode.

However, because two different types of keys are required,

the operator is still at risk of being shut inside if he/she forgets to

remove the trapped key.

Application Examples

Note: The above PL is only the evaluation result of the example. The PL must be evaluated in an actual application by the customer after confirming

the usage conditions.

●Application Overview

1. When the emergency stop switch S1 is pressed.

•The power supply to the motor M1 and M2 is turned OFF immediately when the emergency stop switch S1 is pressed.

•The power supply to the motor M1 is kept OFF until the reset switch S2 is pressed while the emergency stop switch S1 is released.

•When normal operating mode (M1 = ON, M2 = OFF) is selected on the selector switch S8, the power supply to the motor M2 is kept OFF until the guard is closed

and the reset switch S2 and S7 are pressed while the emergency stop switch S1 is released.

•When maintenance mode (M1 = OFF, M2 = ON) is selected on the selector switch S8, the power supply to the motor M2 is kept OFF until the enabling switch is

gripped to the middle position and the reset switch S2 and S7 are pressed while the emergency stop switch S1 is released.

2. Normal operating mode (the emergency stop switch S1 is released)

•Normal operating mode (M1 = ON, M2 = OFF) is selected on the selector switch S8. The enabling switch S3 is disabled.

•Power is supplied to motor M2 when the guard is closed.

•After opening of the guard is permitted by turning ON of the lock release enable signal, the lock release switch S5 is pressed, then the guard lock is released and the

guard is opened. Opening of the guard is detected by S4 and S6, and the power supply to the motor M2 is turned OFF immediately (The power supply to the motor

M1 is kept ON).

•The power supply to the motor M2 is kept OFF until the guard is closed and the reset switch S7 is pressed.

3. Maintenance mode (the emergency stop switch S1 is released)

Safety Precautions

Be sure to read the precautions for All Pushbutton Switches in the website at:http://www.ia.omron.com/.

Indication and Meaning for Safe Use

Installation Environment

• Do not use the switch in locations where explosive or flammable

gasses may be present.

• Do not use the switch submerged in oil or water or in locations

continuously subject to splashes of oil or water. Doing so may

result in oil or water entering the switch.

Wiring

• Connect a fuse in series with the A22TK to protect it from

shortcircuit damage. The value of the breaking current of the fuse

must be calculated by multiplying the rated current by 150% to

200%.

When using the A22TK for an EN rating, use a 10-A fuse of type gI

or gG that complies with IEC 60269.

• Always make sure that the power is turned OFF before wiring the

Switch.

Also, do not touch the terminals or other current-carrying ports

while power is being supplied.

• Check the contact specifications before mounting the Switch

Block. Use an NC contact for a safety circuit. It may not operate

properly. Check the Switch Block for safe operation before use.

• Check the operating specification before mounting the Operation

Unit. It may not operate properly. Check the Operation Unit for safe

operation before use.

Installation

• Do not drop the Switch. Doing so may prevent the Switch from

functioning to its full capability.

• Make sure the Switch is mounted securely to prevent it from falling

off. Otherwise injury may result.

• Mount the Operation Key so that it will not come into contact with

persons in the area when the door is opened and closed. Injury

may result.

• Do not use a Switch as a stopper. Otherwise, the switch may be

damaged and may not operate properly.

• Be sure to use the supplied Lock Ring. Otherwise, the switch may

rotate and may not operate properly.

Others

• Do not attempt to disassemble or modify the Switch. Doing so may

cause the Switch to malfunction.

• The durability of the Switch is greatly influenced by the switching

conditions. Always test the switch under actual working conditions

before application and use it in a switching circuit for which there

are no problems with performance.

• The user must not maintain or repair equipment incorporating the

Switch. Contact the manufacturer of the equipment for any

maintenance or repairs required.

Operating Environment

• This Switch is designed for use indoors.

Using the Switch outdoors may damage it.

• Do not use the Switch where corrosive gases (e.g., H2S, SO2, NH3,

HNO3, or CI2) are present or in locations subject to high

temperature and humidity. Doing so may result in damage to the

Switch as a result of contact failure or corrosion.

• Do not use the Switch in any of the following locations.

• Locations subject to extreme temperature changes

Storage

• Do not store the Switch where corrosive gases (e.g., H2S, SO2,

NH3, HNO3, or Cl2) or dust is present, or in locations subject to high

temperature or high humidity.

Mounting

• Do not tighten the mounting ring more than necessary using tools

such as pointed-nose pliers. Doing so will damage the mounting

ring. The tightening torque is 0.98 to 1.96 N·m.

• Recommended panel thickness: 1 to 5 mm.

Indicates an imminently hazardous

situation which, if not avoided, is likely to

result in serious injury or may result in

death. Additionally there may be severe

property damage.

Indicates a potentially hazardous situation

which, if not avoided, may result in minor

or moderate injury or in property damage.

or avoid doing, to prevent failure to

operate, or undesirable effect on product

performance.

DANGER

Always confirm that safety functions are operational

before stating operation. Wiring mistakes, setting

mistakes, switch failure or other factors may prevent

safety functions from operating. This may result in the

machine continuing to operate, possibly resulting in

human accidents.

CAUTION

If the Operation Unit is separated from the Socket Unit,

the equipment will not stop, creating a hazardous

condition.

Secure the lever on the Socket Unit by using the A22Z-

3380 Lock Plate so that the Operation Unit cannot be

easily separated from the Socket Unit.

(Refer to “Mounting the Lock Plate” at the right.)

[Used in combination with a Slide Key]

The machine may operate, possibly causing injury.

Do not disable safety function by using a spare door

switch operation key or spare key with the door

open.

[Used outside/inside hazardous area]

The machine may operate, possibly causing injury.

Do not disable safety function by using a spare key

outside or inside the hazardous area.

A22TK

Mounting the Lock Plate

1. Confirm that the lever on the Mounting Latch is on the side where

the Operation Unit is secured and then insert the protrusion on the

Lock Plate into the hole in the lever on the Mounting Latch.

2. Press the hole on the Lock Plate onto the protrusion on the Mount-

ing Latch until it clicks into place.

After mounting the Lock Plate, check that the lever does not move.

Operating the Key

•When rotating the key to the total travel position or free position,

the operating force must be 1.47 N·m max.

Wiring

• Terminal screws must be Phillips or slotted M3.5 screws with a

square washer.

• The tightening torque is 1.08 to 1.27 N·m.

• Single wires, stranded wires, and crimp terminals can be

connected to the Switch

• Applicable Wiring Materials:

Twisted strands: 2 mm2 max.

Solid wire: 1.6 mm dia. max.

• After wiring the Switch, maintain an appropriate clearance and

creepage distance.

• Do not pull the lead wires with excessive force. Doing so may

disconnect them.

• The cable cannot be bended repeatedly.

•When bending the cable, provide a bending radius of 45 mm min.

so as not to damage the cable insulation or sheath. Excessive

bending may cause fire or leakage current.

Operating Environment

• The IP65 model is designed with a protective structure so that it will

not sustain damage if it is subjected to water from any direction to

the front of the panel.

• The Switch is intended for indoor use only. Using the Switch

outdoor may cause it to fail.

Using the Microload

Contact failure may occur if a Switch designed for a standard load is

used to switch a microload. Use Switches within the application

ranges shown in the following graph. Even within the application

range, insert a contact protection circuit, if necessary, to prevent the

reduction of life expectancy due to extreme wear on the contacts

caused by loads where inrush current occurs when the contact is

opened and closed.

The minimum applicable load is the N-level reference value. This

value indicates the malfunction reference level for the reliability level

of 60% (λ 60) (conforming to JIS C5003).

The equation, λ 60 = 0.5 x 10-6/time indicates that the estimated

malfunction rate is less than 1/2,000,000 with a reliability level of 60%.

Others

• If the panel is to be coated, make sure that the panel meets the

specified dimensions after coating.

• Due to the structure of the Switch, severe shock or vibration may

cause malfunctions or damage to the Switch.

Also, most Switches are made from resin and will be damaged if

they come into contact with sharp objects. Particularly scratches

on the Operation Unit may create visual and operational

obtrusions.

Handle the Switches with care, and do not throw or drop them.

• Perform maintenance inspections periodically.

• Do not use the key switch to stop/start the machine.

• Mode switching by key must be performed by the operator

specified in the operating manual.

• Apply load current not to exceed the rated value.

• The contact ON/OFF timing is not synchronized. Confirm

performance before application.
