Installation
3.1
Installation of the RTC Module
Only install the RTC Module on a DIN rail. The module must be attached horizontally, with
at least 30 mm (1.2 in.) space at the top and bottom to make sure that the passive aeration
element can function correctly.
When used indoors, the RTC Module must be installed in a control cabinet.
When used outdoors, the RTC Module requires a suitable enclosure that supplies the
following technical specifications (see
Section 1 Technical data, page 7
The RTC Module is only operated via the sc1000 controller (see the user manual for the
sc1000 controller).
Note: The software version of the sc1000 controller must be V3.20 or above.
3.1.1
Power supply to the RTC module
Note: An external deactivation switch is recommended for all installations.
3.2
Connection of process measuring instruments (for NH
4
-N, TSS and
O
2
)
The measurement signals of the sc sensors for measuring NH
4
-N, TSS, Dissolved
Oxygen and Temperature (e.g. AMTAX sc, AN-ISE sc, AISE sc, SOLITAX sc, LDO2 sc,...)
are supplied to the RTC module via the RTC communication card (YAB117) in the sc1000.
3.2.1
Power supply of the sc sensors and the sc1000 controller
See operating instructions of the respective sc sensors and the sc1000 controller.
D A N G E R
Only qualified experts may perform the tasks described in this section of the manual, while
adhering to all locally valid safety regulations.
C A U T I O N
Always lay cables and hoses so that they are straight and do not pose a tripping hazard.
C A U T I O N
Before switching on the power supply, you must refer to the instructions in the relevant operating
manuals.
WA R N I N G
Alternating current may destroy the direct current system and therefore jeopardize user safety.
Never connect an alternating current voltage to the 24 V direct current model.
