KEY TRANSFER SYSTEMS

Electromechanical interlocks

With the presence of coils, micro contacts, timers for the management of operations in which, in addition to the mechanical block, an electrical or signaling consent is required, they are normally installed on:

Perimeter barriers with access requestEntry in the presence of systems with inertial motionPower disconnectors

EXAMPLE 1: ELECTROMECHANICAL INTERLOCK ON PANEL

In order to collect the key that will be used to open the access door to the maintenance area, it is necessary to press the "access request" button. Once the approval has been received from the safety module, which cuts off energy from the system, the coil inside the plate that allows the rotation and extraction of the key, the movement of the key activates 2 signaling microcontacts.

EXAMPLE 2: KEY SWITCHES

Rotating the key allows the system line to which the switch is dedicated to be turned off, the key will then be inserted into other appropriately coded interlocks. It is impossible to restart the system until the key is inserted and turned again.
