Actual signals and parameters 279
DI5 Enables the Interlock function and assigns a digital input
(starting with DI5) to the interlock signal for each PFC relay.
These assignments are defined in the following table and
depend on:
• the number of PFC relays (number of parameters
1401…1403 and 1410 with value = 31 [PFC])
• the Autochange function status (disabled if 8118
AUTOCHNG INTERV = 0.0, and otherwise enabled).
