■ If P2-01 = “1: Output Current”

The iQpump drive can be configured to enter a “sleep” condition based on output current. The drive will enter the sleep mode when the

output current falls below the programmed Sleep Level (P2-02) for a time specified by the Sleep Delay Time (P2-03).

This function is only active during operation in the Auto Mode. The display will indicate “Sleep” alarm when active.

The Sleep Level Type works in conjunction with the Sleep Level (P2-02), Sleep Delay Time (P2-03), and Alternative Sleep Activate

Level (P2-20). A multi-function digital output can be programmed to enable sleep (H1-xx = 82).

■ If P2-01 = “2: Feedback”

The iQpump drive can be configured to enter a “sleep” condition based on the feedback signal. The drive will enter the sleep mode when

the feedback signal rises above the programmed Sleep Level (P2-02) for a time specified by the Sleep Delay Time (P2-03).

This function is only active during operation in the Auto Mode.

The Sleep Level Type works in conjunction with the Sleep Level (P2-02), Sleep Delay Time (P2-03), and Alternative Sleep Activate

Level (P2-20).

Note: The feedback signal depends on the PID direction (b5-09). If the PID operation is programmed Reverse Output

direction, the sleep mode will activate when the feedback signal falls below the programmed Sleep Level (P2-02). The

PID will automatically be reset while sleep mode is active.
