If the Drive Bypass Function is
enabled, the adjustable frequency
drives are no longer Safety Certified
(for using the Safe Stop in versions
where included).
The setting options below are all related to the Cascade

All pumps running and at full speed
[201] Pump1
Running
One or more of the pumps controlled by the
Cascade Controller are running. The function
will also depend on the setting of in

. If set to
[0] No,
Pump

RELAY1, etc. If set to
[1] Yes,
Pump 1 refers to
the pump controlled by the adjustable
frequency drive only (without any of the built-
in relays involved) and Pump 2 to the pump
controlled by the relay RELAY1. See
