ABB 3BSE025349R1 TP854 Baseplate for CI854 (A or B)

Each flame analysis unit consists of two independent channels.

Each channel receives and processes one flame detector signal.

The two detectors can be any combination of the following designs:

- SF810 Flame Scanning Head

- All DFS flame scanning heads

- Flame Rod (Ion Flame Monitoring)

Each detector can be independently configured via the FAU810 pushbutton and display, 

the Flame Explorer engineering tool or Profibus.

The FAU810 can be powered by a single or redundant 24 VDC power supply (+/- 20%).

The FAU810 has a built-in diode auction for power isolation.

Two digital input channels are available for remote parameter switching.

One digital input per sensor.

(Example: Dedicated flame detector parameters can be customised to monitor coal or oil burning)

The FAU810 can be upgraded in the field based on official releases of

new product features through a proprietary firmware download tool.

The supply unit control program runs in the RDCU control unit located in the swing out frame. 

The RDCU is connected to the supply modules by a fibre optic link, and a separate wire set.

If there are parallel supply modules, the controls from the RDCU are distributed

to the modules with an optical branching unit (APBU board).

The RDCU is also connected to the inverter unit with a fibre optic link and to the panel through the panel link.

Typically, the user controls the supply unit with the control devices mounted on the cabinet door.

The use of these control devices is described in the following subsections.

No additional control devices or connections are needed.

However, it is also possible to control the unit with the control panel and through the fieldbus.

Main disconnecting device

The drive is always equipped with a main disconnecting device.

The device is either the main switch-disconnector inside the module (no option +F253 or +F255),

the main switch-disconnector outside the module (option +F253),

or the main breaker outside the module (option +F255). 

The user operates the main switch-disconnector(s) with a handle on the cabinet door.

The breaker is withdrawable; its must be racked out when disconnection is needed.
