2Outputs with StromRel module (optional)
The StromRel module has two galvanically iso-
lated current outputs (0/4 .. 20 mA). The mi-
nus poles of these outputs are connected to-
gether. The maximum load is 500 Ω.
There are also three semiconductor relays,
which are also galvanically isolated. These are
designed for voltages of up to 30 V and cur-
rents of up to 0.12 A. With the contact clo-
sed, the resistance is 25 Ω.
The functions described in the Instruc-
tion Manual can be assigned to the outputs.
Only two of the three outputs are active (C1
and C2).

Description of menu functions Reference Handbook FireGuard 2

3.7.2.1 Lin/Log function –linear or logarithmic signal output
The Lin/Log function is used to set whether the current signal is output in linear (Lin) or lo-
garithmic (Log) form.
This can be useful if very large measuring ranges are to be represented, for example
(Example: FireGuard 0.1 .. 3000 mE/m). With the logarithmic signal output, the Measuring
range can have a minimum value of 0.001.
If a lower value was set in the “From” column in the Measuring range menu, then the si-
gnal is output according to this minimum value (there is no underflow). The measuring range
is transferred in a logarithmic range of 0 .. 1. The measuring range is then output as a cur-
rent range of 0/4 .. 20 mA.
The measuring value is converted into a current value as follows:
Log value = log10 (Lin value / MR from) / log10 (MR to / MR from)
Current (4-20mA) = Log value * 16 + 4 [mA]
The current value is converted back into a measuring value as follows:
Log value = (current (4-20mA) –4) / 16
Lin value = MR from * (MR to / MR from) Log value
Example: MR from = 0.1, MR actual = 3000
