Ramps; Deblocking The Impeller; Temperature Monitoring; Monitoring Equipment - KSB CalioTherm Pro 25 Installation & Operating Manual

7 Operation

7.3.5 Ramps

During normal operation the motor responds to a setpoint change of the pump
controller with maximum dynamic. To prevent pressure surges this dynamic is limited
while the pump set is started up / stopped or when the pump controller changes the
setpoint in large increments. The ramps' dynamic is set via the KSB ServiceTool. The
ramps' function and settings are described in the KSB ServiceTool supplementary
operating manual (reference number 1157.801).

7.3.6 Deblocking the impeller

Function
The pump is started up at maximum torque to remove any mechanical blocking
which may occur (at the impeller or motor shaft). The pump's current input is limited
in this case (protective function). If the blocking cannot be removed, the pump will
stop the start-up attempt, and error code E04 will be displayed. After a short interval
the pump will try to start up again. The start-up attempts are limited to 24 hours.
Once the pump has started up successfully, it will acknowledge the error message;
error code E04 will disappear from the display.
Settings
None

7.3.7 Temperature monitoring

To protect the motor against overheating a sensor monitors the winding
temperature. If the temperature enters the critical range, the motor outputs
warning E05 and the maximum permissible speed is limited. The speed limit settings
are described in the KSB ServiceTool supplementary operating manual (reference
number 1157.801).

7.3.8 Monitoring equipment

The pump set checks that the following values are observed:
▪ Minimum/maximum flow rate
▪ Fluid temperature
The monitoring options flow rate limit (Flow Limit) and high fluid temperature can
be enabled via the KSB ServiceTool. The functions and settings are described in the
KSB ServiceTool supplementary operating manual (reference number 1157.801).

7.3.9 Saving data

Function
The operating data of the pump are saved. Data storage will be maintained also
when the pump is stopped or de-energised. When the pump is started up again, it
will be operated with the data and duty point that were active before the pump was
last stopped.
Settings
None
