TMEC key exchange control unit

The control panel allows you to exchange two numbers of keys (max. 40). In order to release keys from a lower row of the control panel, keys from a higher row must be entered. The same principle applies in reverse: a given number of keys of the first group must be returned to release the second group of keys.

The TMEC key exchange is designed to allow the release of subordinate keys by locking one or more master keys.

The use of this type of solution is usually necessary in situations where there is multiple access to a hazardous area. The device is available in versions with four or more slave keys.

Enclosure: steel sheet
Finish: red polyester paint (RAL 3000)

The system consists of an RTK rotary lock for machine power control, a TMEC control panel, and at least five NX-type access control locks for secure access to the danger zone.
In normal machine operation (motor power on), the operating key A is locked in the RTK, and the access door to the danger zone is closed and locked.

To access the danger zone:

1. the operator removes the operational (master) key A from the RTK rotary lock, which cuts off power to the machine.
2. key A is then placed in the TMEC key exchange, which releases access keys B, C, D, E and F.
3. access(slave) keys B, C, D, E and F can then be placed in their respective NX access control locks, which releases personal keys B', C', D', E' and F' and latches for access to the hazardous area.
The B', C', D', E' and F' personal keys remain with the operator while in the zone to prevent accidental closing of the door and restarting of the machine.
4 To restart the machine, the operator follows the above steps in reverse order.
