Installation and operating instructions Wilo-Rexa PRO 15
PRODUCT DESCRIPTION
US English
3.4.2.
Operating mode S2 (short term operation)
The maximum operating period is specified in
minutes, e.g. S2-15. The pause must last until the
machine temperature is no more than 2 K away from
the temperature of the coolant.
3.4.3.
Operating mode S3 (intermittent operation)
This operating mode defines a combination of pe
-
riods of operation and standstill. With S3 operation,
the values given are always calculated based on a
period of 10 minutes.
Example: S3 25 %
Operating time 25 % of 10 min = 2.5 min / standstill
time 75 % of 10 min = 7.5 min
3.4.4. "Non-immersed operation" operating mode
The "non-immersed operation" operating mode de-
scribes the possibility of the motor emerging during
the drainage pumping sequence in a wet well instal-
lation, which enables a further lowering of the water
level as far as the upper edge of the hydraulics.
During non-immersed operation, the medium
and ambient temperature must not exceed 104 °F
(40 °C).
•
P 13 motor:
Non-immersed operation is permis-
sible in accordance with the specification "Non-
immersed operating mode" on the rating plate.
•
P 17 motor:
Non-immersed operation is not per-
mitted!
3.5. Technical data
* S1 operation when non-immersed is
not
possible
with all motors. Observe the information on the
rating plate.
** Operating mode S3 50% is permissible if the
necessary motor cooling is guaranteed by complete
immersion for at least 1 minute before the motor is
switched back on again.
The specified technical data apply to the standard
pumps in the PRO series.
The technical data for freely configured pumps in
the PRO series can be found in the relevant order
confirmation.
