6.1.1 DESCRIPTION OF INPUTS
MIWII incorporates 2 digital inputs, which can be configured using the ENERVISTA MII SETUP software (
Setpoint >
Relay Configuration
). The default input configuration is as follows:
All elements not defined as PULSE are LEVEL inputs.
In LEVEL inputs, while the voltage level is enough to activate the input, the input performs the function stated in its
configuration.
PULSE inputs are different. In the configuration menu for each input there are several states already defined as Pulse
inputs. When the input recognizes their activation, it performs the function stated in its configuration, independently from
the time it remains activated. For the input to perform again the required function, it is required that the input voltage level
is reset and reactivated.
Figure 6–1: INPUT RESPONSE FOR LEVEL AND PULSE OPTIONS
The minimum operation time for a valid PULSE input is over 0.015 seconds.
Input elements are divided into two groups, besides the
No definition
one. Up to eight elements can be configured to be
activated by the same input, providing that they are all in the same group. Elements belonging to different groups need to
be assigned to different inputs.
In order to configure an input with more than one element from the same group, we must first activate the
OR
button, click
on the
I/O CONFIGURATION
option and select the desired group, then select the desired elements. For inverting an
element, select the
NOT
button. Finally, click the
OK
button.
