5.5.12 Fan Monitoring (optional)
Fig. 5-54 Fan Monitoring
The fan monitoring function indicates whether or not all of the fans are
running at the correct speed in RPM.
A) Frequency setpoint (entry field)
The frequency setpoint for the frequency converter is entered here. A sin-
gle field makes reference to one or more fans.
B) Frequency setpoint (display value)
The frequency setpoint is displayed for each individual fan.
If the parameters have been configured correctly, the respective set-
points in A and B must coincide.
C) Actual frequency value (for B&R controller only)
The actual frequency value is displayed for each individual fan. The ac-
tual value must coincide with the respective setpoint. The value is dis-
played in green if it lies within a tolerance of +2 / -5 Hz. It is displayed in
red if it is out of tolerance. The fan is malfunctioning.
D) Fan status (for S7 controller only)
Indication is displayed here for each individual fan as to whether or not
speed in RPM is within the permissible, internally calculated tolerance. If
everything is OK, the field is green and “OK” appears at the display. If the
tolerance is violated, the field is red and “Error” appears at the display.
The fan is malfunctioning.
E) Fan frequency
Entry of fan frequency in Hz for the standby mode.
F) Standby On-Delay
Entry for delay time until the standby mode is activated.
G) Standby Off-Delay
Entry for delay time until the standby mode is deactivated.

The volume flow control
(option)
Fig. 5-55 Fan monitoring - volume flow control
The volume flow control regulates the cooling section fan frequencies in or-
der to maintain the specified volume flow.
If the volume flow exceeds tolerances “” on page 90) the message “Change
filter F9" is displayed on the main screen and the alarm “Volume flow control
cooling section” triggers.
If the fans in the individual zones are controlled by different frequency con-
verters, the different fan frequency settings are maintained also in normal
operation.
e.g. set C2 = 20.0 Hz,
C3 and C4 = 25.0 Hz.
In controlled operation, the 5 Hz difference between C2 and C3 / C4 is main-
tained.
Commissioning:
Press the ON/OFF key to deactivate volume flow control. The fan speed now
has a fixed value and volume flow is established. Take the displayed actual
value as the new target value. Now activate volume flow control again by
pressing the ON/OFF key. Permissible volume flow tolerances may be en-
tered in the “Rel-“ field. Finish and save the program.
H) Actual value
Current differential pressure, volume flow.
I) Set-point
Volume flow Set-point value.
J) Controlled operation ON/OFF
Activating/deactivating volume flow control.
K) Rel-
Permitted volume flow tolerance.

ECO-Program (option)
Fig. 5-56 Fan monitoring - Eco-Programm
ECO program delays
The specified delay time will expire as soon as the oven is empty and no
request by the upstream belt is pending.
The ECO program will be loaded after the specified time.
The old program will be re-loaded on request by the upstream belt.
The ECO program is deactivated when the input field is on “O”.
Note!
The “ON/OFF” button must be on “ON” in the ECO program.
