10. Error diagnosis

Only the green LED may illuminate if the supply voltage has been correctly connected. If one of the red LEDs
illuminate, there is an error in the system which can be pinpointed with the aid of the LED.
LED
LEDs are not The supply voltage is missing, too
illuminated low or has been connected incor-
rectly
A single red LED Contact edge(s) not connected,
is illuminated connected incorrectly or faulty
One of the contact edge connections
is not being used
Both of the red The transmission line is faulty or has
Transmit LEDs been installed incorrectly
are illuminated
Contact edge(s) not connected,
connected incorrectly or faulty
* If the error is not in the wiring, the function of the electronics can be tested by connecting an 8.2 kΩ
resistor to all SCE inputs on the INDUS rail 7��-242 (INDUS rai 7��-942) electronic evaluation system
(terminals 3, 10 and terminals 3, 11) and to the travelling coil core (connections O and C). If the elec-
tronics work perfectly after performing the test, the safety contact edges must be checked using an
ohmmeter. To do this, the respective connection on the SCE for the electronic evaluation system or for
the travelling coil core must be disconnected and connected to an ohmmeter.
The resistance must be 8.2 kΩ ±500 Ω when the safety contact edge is inactive and must not exceed 500 Ω
when it is active.
** If both of the LEDs for the travelling SCEs (Transmit Opening and Transmit Closing) illuminate, there is
an error in the inductive signal transmission system. The most frequent causes of these errors are bad
coil core connections, incorrectly installed cable system components (see INDUS rail safety transmission
system assembly instructions) or an impermissibly low supply voltage.
The maximum resistance value of the cable loop must not exceed 3 Ω . The resistance value can be
measured by disconnecting the steel cable from the ground terminal and then measuring the resistance
between the end of the steel cable and ground terminal.
Error
Check connections and supply voltage:
- 24 V AC/DC at terminals 8 9
Tolerance range: ±��0%
- Check the connections of the corresponding
- Check safety contact edge(s)*
Any contact edge connections that are not
being used must be permanently bridged
using one of the supplied 8.2 kΩ resistors
- Observe the mech. assembly instructions
- Check transmission coil cores for abrasion.
- Check cable loop; make certain that both
- Check cable / gate leaf contact points.
- Check supply voltage**
- Check the connections of the corresponding
- Check safety contact edge(s)*
