Tab. 2.3
Monitoring of the load supply voltage (PL) takes place in the devices and is passed on to
the CTEL master module.
Since all connected devices use this LED, the display of an error has priority over the dis­
play “OK” (LED illuminated green).
The I-port at which the error has occurred can be determined through the FMT/MMI using
the diagnostic messages.
