Notes/comments:
If the limit in the feedback monitor is exceeded, warning 90, Feedback Mon. is issued. The SLC
monitors warning 90, Feedback Mon. and if the warning becomes true, relay 1 is triggered. Exter-
nal equipment may require service. If the feedback error goes below the limit again within 5 s, the
drive continues and the warning disappears. Reset relay 1 by pressing [Reset] on the LCP.
7.1.12 Wiring Configuration: Compressor
The SmartStart guides the user through the set-up of a refrigeration compressor asking for input data about the compressor and the
refrigeration system on which the drive is running. All terminology and units used within the SmartStart are common refrigeration type
and set up is thus completed in 10–15 easy steps using just 2 keys of the LCP.
