Notes/comments:
If the limit in the feedback monitor is exceeded, warning 90,
Feedback Mon. is issued. The SLC monitors warning 90, Feedback
Mon. and if the warning becomes true, relay 1 is triggered.
External equipment may require service. If the feedback error
goes below the limit again within 5 s, the drive continues and
the warning disappears. Reset relay 1 by pressing [Reset] on the
LCP.

Illustration 12.6 Lead Pump Alternation Wiring Diagram.
Every pump must be connected to 2 contactors (K1/K2 and
K3/K4) with a mechanical interlock. Thermal relays or other
motor overload protection devices must be applied
according to local regulation and/or individual demands.
•
Relay 1 (R1) and relay 2 (R2) are the built-in relays
in the drive.
•
When all relays are de-energized, the 1
st
built-in
relay that is energized cuts in the contactor
corresponding to the pump controlled by the
