Analogu e Output
3.1
Analogue output of delivered
volumetric flow (version RS only)
Using channel 2, the delivered volumetric flow can be
output through the analogue-out module. This
information is purely computational in nature and is
governed by the correct setting of the speed-controlled
compressors delivery rate in the [CONTROL MENU]
menu (see Chapter 1.4.1).
Channel No. Scaling 4 to 20 mA
2
0 to maximum volumetric flow
1)
1) When BLS is active, this corresponds to the sum of
all compressors controlled by BLS.
Note
For the purpose of electrical isolation, an isolation
amplifier must be used immediately downstream of this
analogue output.
3.2
Analogue output
(option only in version SR)
The optional analogue-output module has two 4 to
20 mA outputs.
Channel No. Scaling 4 to 20 mA
1
0 to maximum speed
2
0 to maximum volumetric flow
1)
1) When BLS is active, this corresponds to the sum of
all compressors controlled by BLS.
Note
For the purpose of electrical isolation, an isolation
amplifier must be used immediately downstream of this
analogue output.
