Testing

For a standardize-conformal construction of the safety system, the gate-controller has to give a test
signal before each dangerous movement of the gate. With the test signal the output contacts of the
ISK 76-21 has to open. The controller has to evaluate this change of the output switch status. In the
correct case of testing the controller starts thereupon the movement of the gate. In the other case
the controller has to switch into the "manual mode" operating and has to give an error message.
With the DIP-slide switch S1 the available test signal can be selected. In the switch position A the
testing will be performed when the voltage is applied and in the switch position B the testing will be
performed when no voltage is applied.

With the testing by the controller the ISK-system fulfils the requirement according to
EN12453 „Safety in use of power operated doors and gates" and EN 12978 „Safety
devices for power operated doors and gates".
The operation or the installation of the ISK 76-21 system without testing does not
fulfil any safety requirements.
