Troubleshooting
8.1Overview of the possible errors and malfunctions
8.1.1
Configuration errors
•
Carrier frequencies configured incorrectly (ISD 230)
•
Electrical interfaces configured incorrectly
8.1.2
Mounting errors
•
Units aligned incorrectly to each other
•
Techncial limits of the transmission range exceeded
8.1.3
Electrical installation errors
•
Electrical interfaces on the ISD connected incorrectly
8.1.4
Malfunctions
•
Light path disturbed (obstacles in the cone of light or light path totally interruped)
8.2
Monitoring errors and malfunctions
The ISD is self-monitoring during operation:
•
If the light path is totally interruped, the “Light path interruped“ LED lights up. The LED
blinks if the intensity of the received light is weak, but still sufficient.
•
The “Light path free“ switching output changes from high (+ 24 V) to low (0 V) if the light
path will be totally interruped.
•
ISD 230: the additional “Contamination“ switching output changes from high (+ 24 V) to
low (0 V), if the intensity of the received light from the opposite station is not adquate
due to contamination on the receiver lens (see also
Chapter 5.1.7 Connecting the
function interfaces, Page 30
).
8.3
Troubleshooting
The following are required for troubleshooting purpose using
Table
8-1
:
•
These Operating Instructions
•
Tool
•
A digital measurement device (current/voltage measurement)
The information contained in the table refers to one unit. Troubleshooting should always be
carried out on both units to check their interaction.
