Product description

Ordering code

Special versions
For special versions, which are not listed in the ordering code, 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.

• Interlocks with 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 failure of the power supply or upon activation of the main switch.
• The safety switchgears are classified according to EN ISO 14119 as type 2 interlocking devices.
• 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.

Warning about misuse
In case of improper use or manipulation of the safety switchgear, personal hazards or damages to machinery or plant components cannot be excluded. There are no residual risks, provided that the safety instructions as well as the instructions regarding mounting, commissioning, operation and maintenance are observed.

Exclusion of liability

• We shall accept no liability for damages and malfunctions resulting from defective mounting or failure to comply with the operating instructions manual. The manufacturer shall accept no liability for damages resulting from the use of unauthorised spare parts or accessories.
• For safety reasons, invasive work on the device as well as arbitrary repairs, conversions and modifications to the device are strictly forbidden, the manufacturer shall accept no liability for damages resulting from such invasive work, arbitrary repairs, conversions and/or modifications to the device.

Technical Data

Safety classification of the interlocking function

Basically suitable up to Cat. 1 / PL c.
With 2-channel usage with fault exclusion mechanism (if a fault exclusion to the 1-channel mechanics is authorised)
and suitable logic applicable up to Cat. 3 / PL d
(Determined values can vary depending on the application-specific parameters h op , d op and t cycle as well as the load.)
If multiple safety components are wired in series, the Performance Level to EN ISO 13849-1 will be reduced due to the restricted error detection under certain circumstances.

Safety classification of the guard locking function

• 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. 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 measure need to be realized that have an equivalent safety level.

UL notice
Use Type 4X (Indoor Use) and 12 connector fittings. Tightening torque rating: 4.4 lb in.

Mounting

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

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).

Dimensions
All measurements in mm.

Manual release
(for set-up, maintenance, etc.)
Manual release is realized by turning the triangular key by 180° (M5 triangular key available as accessory), so that 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 plastic cover, which is included in delivery.

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

Emergency release (ordering suffix -N)
(Fitting and actuation 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 labelled 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 in case of an emergency, the orange lever must be turned to the stop in the direction marked by the arrow. 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 extent that the lever can be turned back into its original position. The screw must then be re-tightened

Emergency Exit
(Fitting and actuation only from within the hazardous area)

To activate the emergency exit of the T version in case of an emergency, the orange lever must be turned to the stop in direction marked by the arrow. The emergency exit function of the TD and TU versions is activated by pressing the red pushbutton. In this position, the safety guard can be opened. The blocking condition is cancelled by turning the lever in opposite direction or by pulling back the pushbutton. In unlocked position, the safety guard is protected against unintentional closing.

Electrical connection

General information for electrical connection
The electrical connection may only be carried out by authorised personnel in a deenergized 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

Appropriate cable glands with a suitable degree of protection are to be used. Remove the walls of the mounting holes by inserting the cable entry. All plastic residues must be removed from the switch compartment.

Puncturing the wall of the holes with auxiliary tools (e.g. screwdriver) can cause damage.

Settle length x of the conductor

• On cage clamps (CC) of type s or f: 5 … 6 mm
•  On screw terminals (SK): 7 mm

Contact Options
Contacts shown in a deenergized condition and with the actuator inserted.

Integrated contact kit 12/12 G (with LED)
