Digital inputs configuration
The inputs can be configured as:
•
Two independent inputs for single direction RPM measurements.
•
Input pair for bidirectional RPM measurement.
•
Input pair for dimmer control (up/down and colour shift on simultaneous activation)
•
Input pair for control purposes* (modes: 4 stage input or set/reset)
•
Two independent control inputs* (modes: H/L control, toggle on flank, 4 stage time-based input)
•
[Revolution counter function (New in 2022) not described yet.]
Note*: The digital input can be configured as a control input. This type of function is only used in special
customised libraries, and the function is not described further in this manual.
The DX1 input mode is defined in one of the selected setup profiles.
When the DX module is used as data input for an indicator or mode control of an indicator, the input definition and
its pre-set parameters are defined in the VI-setup profile (VS).
When DX1 is used as interface for external dimmer pushbuttons, the definition and pre-sets are located in the
Product Profile (PP).
Important:
Be careful not to select a VS (indicator input) and a PP (dimmer) both using the same DX1 input(s), if
you make such a selection by accident, the PP will have priority and get access to use the DX1 input for dimming,
and the indicator input defined in the VS will be disabled,
and the indicator will show “Data lost”.
5.7.3.1 Connecting an RPM pickup
The galvanic separation of the digital inputs makes it easy to connect either an NPN or PNP type inductive pickup
sensor. In fact, any type of sensor able to provide digital pulses can be used as RPM input device.
Connecting an NPN type sensor:
Connecting a PNP type sensor:
