10. Commissioning / functional test
The gate s��ste� �ust be tested �or proper �unction a�ter all o� the electrical connections have been
established and the controllers have been turned on. To do this, activate each o� the sa�et�� contact
edges in sequence and check the corresponding reactions o� the switching unit.

11. Error diagnosis

An error can be localised in the s��ste� with the aid o� the LEDs. Onl�� the POWER LED �a�� illu�i-
nate i� the wiring is correct and the controller has been switched on. I� the FAULT CLOSING LED or
FAULT OPENING LED illu�inates, there is an error in the s��ste�.

I� such an error is signalled, the connections o� the individual s��ste�
co�ponents (electronics, cores) should be inspected. I� the error is
not at the connections, the �unction o� the electronics can be tested
b�� connecting an 8.2 kW resistor to each SCE input on the coil core.
I� the electronics work per�ectl�� a�ter per�or�ing the test, the sa�et��
contact edges �ust be checked using an oh��eter. To do this, the
respective connection on the SCE �or the travelling coil core �ust be
disconnected and connected to an oh��eter. The resistance �ust
be 8.2 kW ± 500 W when the SCE is inactive and �ust not exceed
500 W when it is active.
I� the FAULT CLOSING LED and FAULT OPENING LED illu�inate,
there is an error in the signal trans�ission s��ste�.
The �ost �requent causes o� these errors are bad coil core connections and
incorrectl�� installed cable s��ste� co�ponents. The �axi�u� resistance value
o� the cable loop �ust not exceed 3 W. The resistance value can be �easured
b�� disconnecting the steel cable �ro� the gate lea� and then �easuring the
resistance between the end o� the steel cable and gate lea�.
