4.3. Push-button (SET)
The unit contains one push-button, SET
SET, and it can be used for all operational functions. The push-
button is used for setting up the system (also known as auto-configuration), for resetting the indicator
LEDs and the latched output relays, as well as for checking the input connection.
4.3.1. System setup (auto-configuration)
After all sensors and binary lines have been connected, a system setup procedure (also known as
auto-configuration) must be performed. The sequence is initialized by pressing the SET
SET push-button for
two seconds. This causes the sensor and binary LEDs to start blinking. The unit scans these inputs to
see if they are connected; when an input is detected, the corresponding LED lights up to mark that a
connection was found. All inputs that are not connected continue to blink for three more seconds.
Then, all LEDs are turned off. Additionally, the DIP switch setting are stored in the non-volatile memory
during this sequence.
All sensor inputs remain operational even when they have not been auto-configured. System setup is
only used for self-supervision purposes.
Please note that to reconfigure a unit with fewer connections (BI/BO or sensors) than in the previously
memorized setup, one of the DIP switches must be moved back and forth once before the system
setup procedure is carried out. After this, you must wait one minute before you begin the new auto-
configuration sequence.
You can reconfigure a unit with more connections at any time without the wait and without having to
move one of the DIP switches.
4.3.2. Reset
All LED indications and latched trip relays can be reset by pressing the SET
SET push-button for
one second.
Unless the button is pressed, the latched trip relays remain active until the auxiliary power is
disconnected. All LED indications also remain active even when the auxiliary power supply is
disconnected unless the button is pressed. Please refer to the "Non-volatile memory" chapter for more
information.
