Inputs
The system has two type 3 digital inputs (according to IEC/EN 61131-2). Each digital
input is dual channel, and the ground reference is common for all the inputs (see
Technical references on page 96
).
When using digital inputs, it is mandatory that the additional SNS input "V+ (SNS)" is
connected to 24 V DC and that the GND input "V- (SNS)" is connected to the ground in
order to:
l
perform the correct input diagnostic
l
assure the system safety level
The function of each digital input must be programmed through the safeRS3 Designer
application. The available functions are the following:
l
Stop signal
: optional safety function, manages a specific signal to force all the
safety outputs (detection signals, if present) to OFF-state.
l
Restart signal
: optional safety function, manages a specific signal which enables
the control to switch to ON-state the safety outputs related to all the protective fields
with no motion detected.
l
Muting group “N”
: optional safety function, manages a specific signal which allows
the control to ignore the information coming from a selected group of sensors.
l
Activate dynamic configuration
: allows the control to select a specific dynamic
configuration.
l
Fieldbus controlled
(if available): monitors the input status through Fieldbus
communication. For example, a generic ESPE can be connected to the input,
respecting electrical specifications.

Digital input signals on page 114

Input variable behavior
If neither digital input nor OSSD is configured as
Fieldbus controlled
, the behavior of
the input variables is as described below:
