CAUTION
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).
All pumps running and at full speed
One or more of the pumps controlled by the
Cascade Controller are running. The function
will also depend on the setting of in
25-06 Number Of Pumps. If set to [0] No, Pump
1 refers to the pump controlled by relay
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 Table 3.6:
