Assignment of Input/Output Functions
(logic signals to the input/output terminals)
The input and output functions (logic signals) of the physical terminals in the CMS are as-
signed using the I/O matrix in the CMS remote software. Among these, there are signals
whose use is mandatory and those whose use is optional. To help with this assignment, the
CMS remote software provides a link matrix and a link table.
See chapter
7.3.3.4, section
Pressure before valves > min.
Signal to switch off if pressure < min.
If the pressure drops below the minimum value, a
fault shut-down is initiated.
4 Signals for the chains 1 ... 4 are possible.
Safety chain input
User-configurable input for a safety chain function,
see chapter
Curve set selection
Signal for curve set pre-selection (max. 16 possible),
see chapter
Firing rate+/firing rate
−
These signals increase or reduce the burner firing
rate if the regular firing rate input is configured to TPS.
Soft PLC input signal
User-programmable input via PLC
* The signals "Main flame present" are logically connected in series (AND operation).
