Digital outputs configuration
Each of the six digital outputs of the controller are singularly completely configurable.
The status of the digital outputs is displayed on page S.06 and S.06 (0= output inactive, 1=
output active).
By default, all outputs are activated when the related function requires it (for example the fuel
pump output starts operating when the pump must be activated).
Using
the BoardPrg3 it’s possible to reverse the activation by simply ticking the “Reverse
pol
arity” box on the top of the configuration page of every single output.
It is by the way possible to reverse the logic of the outputs directly operating on the controller
(still singularly for each output) using parameter P.3000 for the outputs on the controller (6 bit
in total)
•
A zero-bit means that the output is normally on standby and starts operating when the
related feature requires it.
•
A one-bit means that the output is normally operating and goes on standby when the
related function requires it.
The mapping of the outputs on the controller is:
Bit Value Output
0
1
T.03

T.04

4
T.05

8
T.06

T.07

32
T.08
Basically, if you want to reverse the logic of an output, it is necessary to add, in the relative
parameter, the corresponding value: e.g. If you want to reverse outputs T.05 and T.06 on the
controller, it is necessary to set P.3000 =12 (that is 4+8). By default, all bits are set to zero.
The digital outputs can be used directly as command for devices outside the controller, or for
reporting certain operating conditions.
