Step 12 – S etting PID Sleep Function parameters (P1-04), (P2-01),
(P2-02), (P2-03) and (P2-04).
(NOTE: In the case of a Fan application skip this step and go to Step13)
• The
PID Sleep function is turned on by parameter (P1-04) when set to (=1). This allows the
system to turn off the PID and thus the inverter output so that the pump does not run when
the system level (PSI) is above the set-point. This sleep start level is set by parameter (P2-
01) in a range from 0 – 100% of the maximum inverter output. When the system level drops
below a value (the units are selected by Step 8) set by parameter (P2-03), the sleep
wakeup level, the output of the inverter will turn on. Parameters (P2-02) and (P2-04)
provide delay times in seconds for sleep start level and sleep wakeup level respectively.
Fig. 4 will serve to illustrate this.
