Programmable functions
It is possible to program eight commands, with automatic activation based on signals or events.
The commands are:
Command type Path
Trip Advanced - Functions
Change protection set (from Set A to Set B) Advanced - Functions
Change configuration (from Remote to Local) Settings - Modules - Functions
Reset the contacts of the signalling modules Settings - Modules - Functions
Opening coil command (YO). Settings - Functions
Closing coil command (YC). Settings - Functions
Reset energy counters Measurements - Energies - Function
Reset of the trip signal Advanced - Functions
Each command provides two programming parameters:
• Activation function: event or events (up to eight, in logical AND or OR configuration) that activate the
command.
• Delay: command sending delay, calculated starting from the occurrence of the activation event.
NOTE: the command is sent if the event is present for a time greater than the delay that has
been set.
NOTE: the YO and YC commands are possible only if the coils are present and if all the
operating conditions exist (circuit-breaker open).
System
In the menu Settings - System some system parameters are available:
Date, to set the current date.
Time, to set the current time
Language, to set the language of the menus.
Password, in order to reconfigure the password.
NOTE: the date and time are maintained thanks to an internal battery in the trip unit. In the
event of date and time fault, you are advised to follow the procedure for replacement of the
battery.
Maintenance
The Maintenance function allows the user to be alerted by a Warning alarm that:
• One year has passed since the last maintenance.
• Contact wear has increased by more than 10% compared with the value at the last maintenance.
There are two areas available on the display:
• Activation area (Main page - Menus - Settings - Maintenance): it allows the maintenance function to be
activated.
• Measurements and reset area (Main page - Menus - Measurements - Maintenance): it appears only if the
maintenance function is activated; it provides information related to maintenance (contact wear and dates)
and the command for confirming that maintenance has been carried out (by confirming, the current date
and contact wear values are recorded, and the alarm signal is reset).
The reference date is that of the internal clock, and the elapsed time is calculated both with the trip unit on
and off (provided that the internal battery is working).
NOTE: manual modification of the date can cause variations in the calculation of the time
elapsed, and therefore in the date of the next maintenance.
NOTE: the maintenance signal due to increased contact wear is active for values higher than
20 %.
