3. Matching the number of ebmpapst fans to the number of fans in the system configuration (menu 3-1)
In the case of a two-row gas cooler package, the number of ebmpapst fans does not match those in the system
configuration and must be adjusted. The number of fans in the system configuration must be half the number of
ebmpapst fans.
Up to 24 ebmpapst fans are supported.
4. Removal of an ebmpapst fan
•
For example, this function is required for the replacement of a defective fan
5. Emergency operation function of an ebmpapst fan
Every ebmpapst fan has its own emergency operation function (refer to the manual of the ebmpapst fans for
details). The emergency operation function is
always activated for every
fan automatically by the pack
controller via the Modbus and is configured as follows:
•
In the event of failure of the Modbus communication, the emergency operation starts after a delay time of
30 seconds
•
The fan runs at 80% of its speed during emergency operation
Practical tip:
It is recommended to document the serial numbers, Modbus addresses and switching
sequences of the ebmpapst fans in the gas cooler package. For other tips, see also chapter
Inbetriebnahme Lüftersteuerung per Modbus
In the case of interrupted Modbus communication (e.g. during service work or switching off the pack
controller), the fans
always go automatically
into emergency operation. If this does not happen for a
fan (e.g. reserve fan), these fans must be disconnected from the power supply.
