Installation
3.3.1
PHOSPHAX sc analyzer power supply
Refer to the PHOSPHAX sc manual.
3.4
sc1000 controller connection
Connect the SUB-D plug supplied to a dual-core, sheathed data cable (signal or bus
cable). For further information regarding the data cable connection, refer to the enclosed
assembly instructions.
3.5
Flow rate signal connection
If a flow rate measurement signal of 4 to 20 mA is available, connect it to the analog input
of the RTC module.
3.6
Connection to the automation unit on the plant side
Depending on the variant and option, the RTC101 P-Module is equipped with various
components that must be connected to the plant's automation unit.
•
The volumetric flow rate is provided to the RTC module as a 0/4 to 20 mA signal for all
variants and options.
•
The precipitant volume to be metered is delivered by the RTC module as a 0/4 to
20 mA signal for all variants and options.
Alternatively, the precipitant volume can also be output by the fieldbus variants
provided by the sc1000 (see sc1000 operating instructions).
•
The RTC module supplies the digital output signal for activating the precipitant pump
at 0 V or 24 V.
•
The RTC module supplies a collective fault message at 0 V (fault) or 24 V (device
functional).
