Problem
Cause/Solution
Incorrect display reaction when the 
display is touched
Calibrate touch screen with finger or stylus. If this is not possible: Start factory 
calibration through web access.
No trend line available.
Configure the logger in the appropriate probe.
Communication problems
Check the probe plug, check probe cable damage, check network plug and cable at 
sc1000 networks.
LED indicator in the probe module 
blinks red
LED indicator in the probe module is 
turned off
Check the fuses, if the probe module is connected to power supply.
Missing measured values after 
changing probe (mA output card, 
fieldbus card)
New configuration for the output cards is necessary. Configure the new probe with its 
serial number. After that, delete the not used probe in the device management.
Local web access is not available
Check the Ethernet connection, LAN configuration and IP address in the 
SYSTEM SETUP, BROWSER ACCESS menu. 
Local web access is blocked with the 
“MENU ACCESS” message

Check if the probes are connected. If the probes are connected, scan for new 
devices. Check the measurement screen configuration. If no device is configured add 
it to the measurement screen configuration.
New devices (probes, modules) are 
connected to the sc1000 controller 
but were not listed during initial bus 
scan
Check whether missing devices are connected to local or – when installed – to 
remote probe modules. Use the serial numbers for identification.
For remote probe modules check proper termination of all network cables.
For local probe modules retry with interchanged device connectors.
