Warning or fault indications
If certain parameters within the PLM approach or exceed preset limits, a warning condition or fault condition
may arise. One or more LEDs will then provide an appropriate visual indication. A textual on-screen descrip-
tion of the condition will also be displayed adjacent to the LED(s).
The LEDs can show three colors, each conveying a different status.
