4027 PID 1 PARAM SET
Defines how selections are made between PID Set 1 and PID Set 2.
PID parameter set selection. When set 1 is selected, parameters 4001…4026 are used.
When set 2 is selected, parameters 4101…4126 are used.
0 = SET 1 – PID Set 1 (parameters 4001…4026) is active.
1 = DI1 – Defines digital input DI1 as the control for PID Set selection.
• Activating the digital input selects PID Set 2.
• De-activating the digital input selects PID Set 1.
2…6 = DI2…DI6 – Defines digital input DI2…DI6 as the control for PID Set selection.
•See DI1 above.
7 = SET 2 – PID Set 2 (parameters 4101…4126) is active.
8…11 = TIMER FUNCTION 1…4 – Defines the Timer function as the control for the PID Set selection (Timer function de-
activated = PID Set 1; Timer function activated = PID Set 2)
• See parameter Group 36: Timer Functions.
-1 = DI1(INV) – Defines an inverted digital input DI1 as the control for PID Set selection.
• Activating the digital input selects PID Set 1.
• De-activating the digital input selects PID Set 2.
-2…-6 = DI2(INV)…DI6(INV) – Defines an inverted digital input DI2…DI6 as the control for PID Set selection.
•See DI1(INV) above.
