Note about the safety classification
Safety consideration of the locking 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 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 consideration of the 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.
Warning: The safety consideration of the unlocking function is only valid for devices with a monitored locking function Quiescent current version (see type 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.
Warning
- 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 realised 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
Warning: 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.
Warning: 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 realised 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.
Notentsperrung (Bestellindex -N)
(Fitting and actuation only from outside the hazardous area)
Warning: The emergency unlocking should only be used in an emergency. The safety interlock must be installed and/or protected in such a way that: an unintentional opening of the tumbler is prevented by the emergency release. The emergency unlocking must be clear must be marked with the message that it is only to be used in an emergency. The enclosed sticker can be used for this be used.
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.
Escape release
(Attachment and operation only within the danger area)
To release the escape release for version T, turn the orange lever in the direction of the arrow as far as it will go. The Escape release for the TD and TU versions is carried out by pressing the red push button. The protective device can be opened in this position. The locking position is activated by turning the lever back Opposite direction or retraction of the impact button is canceled. The protective device is in the unlocked position secured against accidental closing.
Electrical connection
General information for electrical connection
Warning
- The electrical connection may only be carried out by authorised personnel in a de-energised condition.
- If the risk analysis requires safely monitored locking, those with the symbol to integrate marked contacts into the safety circuit.
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.
Tip: Piercing the bore walls with auxiliary tools (e.g. screwdrivers) 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
