Product description

Ordering code
This operating instructions manual applies to the following types:

AZM150SK-➀R➁➂➃-➄-➅

Standard coded actuator (not included in delivery)

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

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.

Purpose
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 AZM150 solenoid interlocks with individual coding offer higher protection against tampering and remain off when the guard system is unlocked or open.

Interlocks with the power to lock principle may only be used in special cases after a thorough evaluation of the accident risk since the safety guard can be opened immediately on the failure of the power supply or upon activation of the main switch.

The safety switchgear is classified according to EN ISO 14119 as type 2 interlocking devices. Designs with individual coding are classified as highly coded.

Manual release (for set-up, maintenance, etc.)
The rear and cover-side manual release can be actuated independently of one another. Check that both are in the starting position when putting the device into operation.
The manual release is realized by turning the triangular key so that 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. After being put into operation, the manual release must be secured by installing the seals, which are included in the delivery.

Triangular key TK-M5 (101100887) is available as an accessory.

Emergency release (ordering suffix -N)
(Fitting only from outside the hazardous area)

The emergency release should only be used in an emergency.
The solenoid interlock should be installed and/or protected so that an inadvertent opening of the interlock by an emergency release can be prevented.
The emergency release must be clearly labeled that it should only be used in an emergency. The label can be used that was included in the delivery.

To activate the emergency release, turn the red lever 90 in the direction of the arrow as far as it will go. In this position, the safety guard can be opened. The lever is latched and cannot be returned to its original position. To cancel the blocking condition, the central mounting screw must be loosened to such an extent that the lever can be turned back into its original position. The screw must then be re-tightened.

Operating instructions Solenoid interlock

Emergency exit (Ordering suffix -T)
(Fitting and actuation only from within the hazardous area) To activate the emergency exit of version T, turn the red lever 90 in the direction of the arrow as far as it will go. In this position, the safety guard can be opened. The blocked position is canceled by turning the lever in the opposite direction. In an unlocked position, the safety guard is protected against unintentional closing.

Emergency release / Emergency exit

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.

Safety classification of the interlock function

MTTF D=B10D/0,1 x nop
nop=D op x hop x 3600s/h/t cycle

If the device is used as an interlock for personal safety, a safety classification of the guard locking function is required.
When classifying the interlock function, a distinction must be made between monitoring of the interlock function (locking function) and controlling the unlocking function.
The following safety classification of the unlocking function is based on the application of the principle of safety energy disconnection for the solenoid supply.
The classification of the unlocking function is only valid for devices with monitored guard locking function and in the power to unlock version (see ordering code).
A fault exclusion for the guard locking function can be assumed by an external safety energy disconnection.
In this case, the guard locking function does not have an effect on the failure probability of the unlock function.

Operating instructions Solenoid interlock

The safety level of the unlock function is determined exclusively by the external safety power shutdown.

Fault exclusion with regard to wiring routing must be observed.
If for a certain application the power to unlock version of a solenoid interlock cannot be used, for this exception an interlock with power to lock can be used if additional safety measures need to be realized that have an equivalent safety level.

Assembly

General mounting instructions
Please observe the remarks of the standards
EN ISO 12100, EN ISO 14119 and EN ISO 14120.

4 M5 holes are provided for mounting the enclosure. The solenoid interlock is double insulated. The use of an earth wire is not authorized. The solenoid interlock must not be used as an end stop. Any mounting position. The mounting position however must be chosen so that the ingress of dirt and soiling in the used opening is avoided. Unused actuator openings must be sealed with slot sealing plugs.

 Detailed information on actuators with standard coding (not included in delivery) AZM150-B1, AZM150-B5 and AZM150-B6 and their mounting can be found in the actuator operating instructions.
The insertion funnel on the head of the interlock allows insertion of a flexible actuator with an axial offset of ≤ ±1 and a height offset of ≤ ±1. The actuator must be inserted into the actuator head easily. For doors that do not ensure this is possible, a door catch must be installed to prevent damage to the device.
When used in ambient temperatures > 40°C, the solenoid interlock must be protected against contact with inflammable materials or inadvertent personal contact.

Choosing the actuating planes
Offsetting the actuating head enables actuation of 8 levels.

1. Cover screws must be loosened
2. Remove cover
3. Turn to actuate head to the desired position
4. Fit the cover and engage, tighten the cover screws (torque 0.5 Nm)

Do not lever out the side tabs. Levering out the tabs will damage the device.

Operating instructions Solenoid interlock

AZM150

Mounting of individually coded actuators
The marks on the used actuator opening of the solenoid interlock and on the actuator must be opposite.

In the as-delivery condition, the actuator of the individually coded safety switch AZM150 -… I is inserted in the upper actuator inlet.
On delivery, the actuator is in inserted condition. For power-to-unlock components, the actuator must be released by means of manual release. If the triangular key is turned 90°, 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.

The actuator must be permanently fitted to the safety guards and protected against displacement by suitable measures (tamperproof screws, gluing, drilling of the screw heads).
Please observe that, when fixing the switch e.g. by means of riveting or welding, the insertion depth of the actuator is not modified. There are different actuator types available.
The actuators AZM150-B1 and AZM150-B5 are preferably used for sliding and removable safety guards. For hinged guards, the AZM150B6L or AZM150-B6R actuator.
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 axis of the hinge must be d mm above and in a parallel plane to the top surface of the safety switch. The basis set provides a minimum radius of Rmin.
Setting screw
The AZM150-B6L or AZM150-B6R actuator is set to the smallest radius in the factory. To increase the radius, the setting screws a + b must be turned by means of a hexagonal key A/F 2 mm.

Strength of the actuator screws 5.6.

 Set-up and maintenance

Functional testing
The safety function of the safety components must be tested. The following conditions must be previously checked and met:

1. Fitting of the solenoid interlock and the actuator
2. Check the integrity of the cable entry and connections
3. Check the switch enclosure for damage
4. Check that both the cover-side and rear manual releases are in the starting position

Maintenance
A regular visual inspection and functional test, including the following steps, is recommended:

1. Check for tight installation of the actuator and the switch
