received by serial communication. Writing from Serial
communication is done to parameter 364 (terminal 42)
and 365 (terminal 45). This function is limited to the
following protocols: FC bus, Profibus, LonWorks FTP,
DeviceNet, Metasys N2 and Modbus RTU.
Fire Mode active is indicated on the output when ac-
tivated via input 16 or 17.
Fire Mode bypass is indicated on the output when
Fire Mode has been active and a certain trip occurred
(please see description of Fire Mode). A delay for this
indication can be programmed in parameter 432.
Please select Fire Mode bypass in parameter 430 to
enable this function.

1 - 32000 Hz
Function:
This parameter allows scaling of the pulse output sig-
nal.
Description of choice:
Set the desired value.
321 Terminal 45, output
(AO 45 FUNCTION)
Value:
See description of parameter 319 Terminal 42,
Output.
Function:
This output can function both as a digital or an analog
output. When used as a digital output (data value [0]-
[26]) it generates a 24 V (max. 40 mA) signal. For the
analog outputs (data value [27] - [41]) there is a choice
of 0-20 mA, 4-20 mA or a pulse sequence.
Description of choice:
See description of parameter 319 Terminal 42, Output.
322 Terminal 45, output, pulse scaling
(AO 45 PULS SCALE)
Value:
1 - 32000 Hz
Function:
This parameter allows scaling of the pulse output sig-
nal.
Description of choice:
Set the desired value.
