Table 22 continued: Group 81: PFA Control
4 = DI4 – Enables the Interlock function and assigns a digital input (starting with DI4) to the interlock signal for each PFA relay. These assignments are
dened in the following table and depend on:
• the number of PFA relays [number of parameters 1401…1403 and 1410…1412 with value = 31 (PFA)]
• the Autochange function status (disabled if 8118 AUTOCHNG INTERV = 0.0, and otherwise enabled).
No. PFA relays Autochange disabled (P 8118) Autochange enabled (P 8118)
0 DI1…DI3: Free Not allowed
DI4: Speed Reg Motor

5 = DI5 – Enables the Interlock function and assigns a digital input (starting with DI5) to the interlock signal for each PFA relay. These assignments are
dened in the following table and depend on:
• the number of PFA relays [number of parameters 1401…1403 and 1410…1412 with value = 31 (PFA)]
• the Autochange function status (disabled if 8118 AUTOCHNG INTERV = 0.0, and otherwise enabled).

6 = DI6 – Enables the Interlock function and assigns digital input DI6 to the interlock signal for the speed regulated motor.
• Requires 8118 AUTOCHNG INTERV = 0.0.
