6. Alarm signalling
The pack controller outputs the following messages in the event of faults:
• A status is requested from each ebmpapst fan via the Modbus. If the status of a fan has a value greater
than zero, the message "Motorschutz Lx" (x can have the values 1..12) is output. The priority of the
alarm is set in menu 3-7.
At the same time, a second message is output in which an error status is transmitted. This message is
structured as follows:
Example message: L yy A:zz xxxxxxxx
L
: fan
yy : switching sequence of the fan from 1..12
A:zz : address 10..33
xxxxxxxx : hexadecimal error code (refer to the manual of the ebmpapst fans for details).
• " Comm.Error Fx ":
This message is output if no ebmpapst fans are registered in the system or where the fan number "--" is
registered for at least one fan.
• " Comm.Error Fx " (x can be the values 1..12):
This message is output if communication with fan Lx is not possible.
Note: this response is evaluated for each request and an internal error counter is incremented for each
error. An alarm is signalled if this value reaches 5.
7. Manual Mode
In manual mode, the fans can be controlled between 0..100% during the normal operation (menu 3-2-2-1). The
message "
EBM Manual Run" is output if manual mode is activated. Manual mode is automatically deactivated
after 60 minutes for the system safety.

To the submenu for defining the switching sequence.
The switching sequence (of the stages in the gas cooler package) for the controllers of the pack
controller are set in the submenu. The switching sequence must be assigned for the physical
position in the gas cooler package (see above point "
2. Defining configuration of the switching
sequence"):
-- : Switching sequence has not been assigned and a message is output.
This state is not permissible; the fan must be disconnected from the power supply otherwise it
will run with 80% of its output in emergency operation.
0*: fan is removed from the switching sequence list.
* Can only be set if authorisation = Master
