2197 Manual release for Power to unlock

Only if the information described in this operating instructions manual are realised correctly, the safety function and therefore the compliance with the Machinery Directive is maintained.

2.2 Special versions

For special versions, which are not listed in the order code below 2.1, these specifications apply accordingly, provided that they correspond to the standard version.

2.3 Destination and use

The solenoid interlock has been designed to prevent in conjunction with the control part of a machine, movable safety guards from being opened before hazardous conditions have been eliminated. The AZM 170 I solenoid interlocks with individual coding offer a higher protection against tampering.

Interlocks with the power to lock principle may only be used in special cases after a thorough evaluation of the accident risk, since the guarding device can immediately be opened on failure of the electrical power supply or when the main switch is opened.

The safety switchgear units are classified as type 2 interlocking devices in accordance with ISO 14119 and are rated as highly coded.

Manual release

A manual release is available as a mounting tool and in the event of a power failure in case the power to unlock principle is used. If the triangular key is turned 180°, the locking bolt is pulled into the unlocking position. Please ensure that jamming by external influence on the actuator is avoided. The normal locking function is only restored after the triangular key has been returned to its original position. After being put into operation, the manual release must be secured by installing the sealing plug, which is included in delivery.

Emergency exit

Fitting and actuation only from within the hazardous area. To activate the emergency exit, turn the red lever in the direction of the arrow to the end stop. Please ensure that jamming by external influence on the actuator is avoided.

The user must evaluate and design the safety chain in accordance with the relevant standards and the required safety level.

The entire concept of the control system, in which the safety component is integrated, must be validated to the relevant standards.

If multiple safety components are wired in series, the Performance Level to ISO 13849-1 will be reduced due to the restricted error detection under certain circumstances.

3. Mounting

3.1 General mounting instructions

On delivery, the actuator is in inserted condition. For power-to-unlock components, the actuator must be released by means of the manual release. If the triangular key is turned 180°, the locking bolt is pulled into the unlocking position. The normal locking function is only restored after the triangular key has been returned to its original position.

Two mounting holes are provided for fixing the enclosure. The solenoid interlock is double insulated. The use of an earth wire is not authorised. The solenoid interlock must not be used as an end stop. Any mounting position. The mounting position must be chosen so as to avoid the penetration of dirt in the used holes. The unused opening must be sealed by means of slot sealing plugs. Tightening force for the Torx T10 cover screws 0.7 ... 1 Nm.

The safety component and the actuator must be permanently fitted to the safety guards and protected against displacement by suitable measures (tamperproof screws, gluing, drilling, pinning).

Please observe the relevant requirements of the standards ISO 12100, ISO 14119 and ISO 14120.

Mounting of the actuator

The marks on the used actuator opening of the solenoid interlock and on the actuator must be opposite.

Please observe that, when fixing the switch e.g. by means of rivetting or welding, the insertion depth of the actuator is not modified. Different actuator forms are available. The actuators B1 and B5 are preferably used for sliding and removable safety guards. For hinged guards, the B6R and B6L actuators.

When the switch is fitted on a hinged safety guard, please ensure that the point of rotation is located within the range of the upper surface of the safety switch, in which the actuator hook is inserted (refer to table).

The B6L or B6R actuators are set to the smallest radius in factory. To

increase the radius, the setting screws a + b must be turned by means

of a hexagonal key A/F 2.5 mm.

4. Electrical connection

4.1 General information for electrical connection

The electrical connection may only be carried out by authorised personnel in a de-energised condition.

If the risk analysis indicates the use of a monitored interlock they are to be connected in the safety circuit with the contacts indicated with the symbol .

For the cable entry, suitable cable glands with an appropriate degree of protection must be used.

Cut clamp terminals

The IDC method of termination (cut clamp technology) enables connecting flexible wires with cable section 0.75 - 1 mm2 without using conductor ferrules. To this effect, strip the wire according to the drawing (refer to the wiring example) and insert it into the cable gland, close the cable gland, push the conductors in the groove of the cover (refer to wiring example) and screw the cover back. Observe that the individual conductors remain in position to avoid jamming.

70 mm

Screw terminals (SK version)

Unscrew the cover of the enclosure. Connect the cables to the terminal block. Use insulated conductor ferrules to that effect. Screw the cover back on the enclosure.
