If fan monitoring is deactivated (value "0"),
only the monitoring of the fans is deactivat-
ed. The fans themselves will continue to
run even after monitoring has been deac-
tivated. The fan symbols will be greyed
out, both in the graphical representation
on the Web interface, and on the optional
display with touch function. The display of
the speed values will change to "--". In the
tree structure, the speed values will be set
to "0", and the status of the corresponding
fan will change to "Off".

In the operating modes "Automatic", "Man-
ual" and "Minimum", the fans will at least
run at this set speed.
"Automatic" operating mode
In automatic mode, the fans are controlled
to the temperature difference between the
server outlet temperature and the adjusta-
ble setpoint. If this difference is less than
or equal to the "DtMin" value, the fans will
run at the minimum speed set here.
"Minimum" operating mode
All fans will always run at the minimum
speed set here.
"Manual" operating mode
If a speed is entered which is less than the
minimum speed set here, the value is au-
tomatically corrected to the minimum
speed. Exception: If a speed of "0%" is en-
tered, the fans will be switched off.
SamplingRate
10
60
Time delay for the control valve in sec-
onds.
P
1
30
P amount:
Parameter for setting the propor-
tional amount. This is set as a per-
centage [%] between 1 and 30%
(presetting: 10%).
Setting of the PID control algorithm inte-
grated into the LCP software. The default
values should only be changed in excep-
tional cases, since the percentages affect
both the speed and the accuracy of con-
trol.
I
20
150
I amount:
Parameter for setting the integral
amount. This is set in seconds [s]
between 20 and 150 s (preset to:
80 s).
D
0
50
D amount:
Parameter for setting the differen-
tial amount. This is set in amount
per second [1/s] between 0 and
50/s (preset to 0/s).
CwValue
1000
9999
Specific thermal capacity of the cooling
medium. This value only needs to be ad-
justed if the cooling medium used is
changed.
