PIT ACCESS MONITORING SYSTEM FOR LIFTING PLATFORMS
PATENTED STRIKE PLATE
WITH UNLOCKING TRIANGLE AND MANUAL RESET SAFETY SWITCH
TEC41-RM
Instruction manual
Intended Use
The pit access monitoring system, consisting of our patented strike plate with unlocking triangle and manual reset safety switch TEC41-RM connected to its special contact bridge (see Picture 1), is only used as intended:
• as an electro-mechanical safety system for lifting platforms (home lifts).
• in combination with a certified safety door lock and a separate door contact.
• observing the information and safety instructions in this manual.
 |
Any other use is considered improper and may result in personal injury and/or property damage. |
Operating Principle
When the landing door is unlocked by means of a triangular release key, its inbuilt NC safety switch gets forcibly opened (positive opening) and therefore the special bridge connected to the safety switch remains “opened”, too, i.e. deactivated as long as the safety switch is not brought back to its closed position by means of its manual reset.
This implies that the platform cannot operate even if the door gets closed and locked (accidentally or voluntarily). The safety switch (which is solidly fixed to the strike plate with metal rivets) can be reset only through the hole which is located in the panel edge, using a standard screw driver (see Picture 2).

Installation
Please note: the TEC41-RM should be installed with the switch pointing upwards so that it can be connected to its special bridge in the most direct way (thus avoiding any risk of mechanical interference between connection wires and strike plate mechanism and/or any sharp edges in the door leaf frame). (See Picture 3)
Electrical connections
Please note: when connecting the special bridge to the safety switch NC contact, the use of the M20x1,5 cable gland (included) is highly recommended for maximum protection. (See Picture 4)

The special bridge wires must be fully protected against mechanical damage. The exposed length of wires running from the special bridge to the opening in the door leaf must be covered by a suitable metal plate or guard (see picture 5). As an alternative the exposed wires must run inside a suitable protection conduit. |
The reset hole in the TEC41-RM should be hidden by a removable cover or plug. Once that the TEC41-RM and the special bridge have been installed and connected
• please check good adjustment and smooth movement of the door lock bolt into the strike.
Additional note: in order to get a perfect alignment between the bolt and the strike in a swift and effective way, we recommend the use of our specific centring tool TEC-FIT. (See Picture 6)
• please check easy accessibility and good functioning of the safety-switch reset:
1) open the door by means of the triangular release key
2) remove the reset hole cover (if used)
3) reset the switch using a suitable flat-head screwdriver (see Picture 2)
Maintenance
1) check that the fixing screws are tightly fastened.
2) check adjustment of bolt to strike plate (centring).
3) remove all deposit of dust or dirt.
Special requirements
|
|
The unlocking triangle in the door lock must be made inaccessible (no key hole in the door frame) |

Earthing of the door is required to prevent short circuit |
Note di sicurezza
|
All the safety measures required to prevent accidents to maintenance operators and platform users must be always taken. Warning: once the door has been unlocked by release key, press the button to simulate a call and make sure that the door lock safety contact is working correctly. Then proceed with the safe blocking of the door to prevent it from closing accidentally. |
