F4
Off INIT state
Flashing green Pre-Operational state
Single flash green Safe-Operational state
Steady green Operational state
ERR
F5 Off Normal behavior
Flashing red Invalid configuration: General Configuration Error.
Possible reason: State change commanded by the master is
impossible due to register or object settings
Single flash red Local error: slave device application has changed the
EtherCAT® state autonomously.
Possible reasons:
l
a host watchdog timeout has occurred
l
synchronization error, the device enters the Safe-
Operational state automatically
Double flash red Application watchdog timeout: an application watchdog timeout
has occurred.
Possible reason: Sync Manager watchdog timeout

3.3 Control unit inputs
3.3.1 Introduction
The system has two type 3 dual channel digital inputs (according to IEC/EN 61131-2). Alternatively, the four
channels can be used as single channel digital inputs (category 2). The ground reference is common for all the
inputs (see "Technical references" on page104).
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
3.3.2 Input functions
The function of each digital input must be programmed through the Inxpect Safety application. The available
functions are the following:
l
Stop signal: additional safety-related function, which manages a specific signal to force all the safety
outputs (detection signals, if present) to OFF-state.
l
Restart signal: additional safety-related function, which manages a specific signal which enables the
control unit to switch to ON-state the safety outputs related to all the detection fields with no motion
detected.
l
Muting group “N”: additional safety-related function, which manages a specific signal, allowing the control
unit to ignore the information from a selected sensor group.
l
Dynamic configuration switch: additional safety-related function, which allows the control unit to select a
specific dynamic configuration.
l
Fieldbus controlled (if available): additional safety-related function monitors the input status through
Fieldbus communication. For example, a generic ESPE can be connected to the input, respecting electrical
specifications.
