14.5.6.1 Information on the trip and opening data
The PR123/P unit saves all the information relating to the type of protection tripped, the opening data, the date and time. Using the "i Test" key
makes the release show all these data directly on the display. There is no need for an auxiliary power supply for this function. With an auxiliary
power supply, the information is shown immediately on the display without the need to press the "i Test" key and remains displayed indefinitely
until you press the key.
The information remains available for 48 hours with dead relay. The data relating to the last 20 trips are stored in the unit's memory. By connecting
a PR030/B battery unit and PR010/T or a BT030 wireless communication unit, you can retrieve the information relating to the last 20 trips recorded.
Access to view the opening data is via the Historicals submenu in the Measurements menu. The following is an example of the information provided:
Again in the Measurements menu, you can view the percentage of contact wear, which is an indication of the electrical life of the electrical contacts
in the circuit-breaker.
In any case, functionality of the relay is in no way modified by the presence of the wear messages.
The prealarm message (wear > 80%, "warning" LED lighting up) indicates that the wear has reached a high value. The alarm message (100%
wear, "alarm" LED lighting up) indicates that it is necessary to check the state of contact wear.
The percentage of wear depends on the number of openings carried out by the circuit-breaker and by the absolute current interrupted during
each of them.
