Observations:
When the controller is switched on: the LED "Power" on the front panel of the

device and the LED "Power On" on the rear panel of the device are lit.
The LED's light up for approx. 3 seconds on the front panel of the device when

the controller is switched off and subsequently switched on and a signal tone is
audible. The LED "Power On" on the rear panel of the device is lit.
Possible causes and solving the problem
Miscellaneous
Check whether communication can be established with the controller: Connect
–
the controller with a USB cable or an Ethernet cross-over cable to a PC /
notebook on which the FibroManager has been installed. Should the controller
be displayed in the "Quick Start" dialog and can be added to the tree view of the
FibroManager, then the corresponding interface is functional.
Read out the event memory and check for error messages. Should a device
–
error be present, please contact the technical support and if required, send in
the controller for repairs.
Description
Fibre is not yet checked.
Fibre check is running.
Fibre is ready for
measurement.
No fibre was detected or
the connected fibre is too
long for the controller
model.
The fibre connector at the
controller has too high
attenuation or return loss.
The fibre termination has
too high return loss.
The fibre shows high
point losses and / or
attenuation.

Troubleshooting
Check channel
Await the end of the check. If no other status is
displayed within 1 minute, then cancel the check and
restart it.
---
This message is displayed when no fibre is connected
or the fibre is too short or too long. In this case, a fibre
must be connected respectively the length of the sensor
fibre must be checked (at least 100 m, not longer than
100 m of the range of the controller). Furthermore the
sensor fibre must be checked for possible fibre breaks.
Clean as described in this document. If necessary,
replace the fibre-optical connector of the sensor cable.
Terminate the sensor fibre correctly as described in the
installation manual. If necessary, check the sensor fibre
for fibre breaks.
Check the backscatter curve with the FibroManager and
compare the attenuation with the requirements as
specified in the operation manual. If necessary, contact
the support department or install a correct sensor cable.
