272 Actual signals and parameters
2 = DI2 – Enables the Interlock function, and assigns a digital input (starting with DI2)
to the interlock signal for each PFA relay. These assignments are defined in the
following table and depend on:
• The number of PFA relays (number of parameters 1401…1403 and 1410) with
value = 31 (PFA).
• The Autochange function status (disabled if 8118 AUTOCHNG INTERV = 0, and
otherwise enabled).
Note: MREL-01 required for PFA relays 2, 3 and 4.
3 = DI3 – Enables the Interlocks function, and assigns a digital input (starting with DI3)
to the interlock signal for each PFA relay. These assignments are defined in the
following table and depend on:
• The number of PFA relays (number of parameters 1401…1403 and 1410) with
value = 31 (PFA).
• The Autochange function status (disabled if 8118 AUTOCHNG INTERV = 0, and
otherwise enabled).
