3.4.3.1. Graphic ammeter and voltmeter
Graphic ammeter and voltmeter options are available in the default page (the voltmeter is only activated if module PR330/V is
installed).
The levels of the available measurements are displayed by a vertical bar.
The current (phase) and voltage (netwwork) values are positioned along the abscissae, with the reference and rated value setting
along the ordinate: an intermediate line indicates the 1In value for the current values and the rated voltage for the voltage values.
Example: if the bar corresponding to current I1 exceeds the intermediate line, it means that the measured value is higher than 1In.
3.4.3.2.

CB and protection release alarms

Information about the state of the protection release and CB is always available at the bottom left of the display (See par. 1.4.3
Display Ref.2).
The ABB logo appears in the absence of alarms.
If one or more alarms have occurred, they will be displayed by a message that flashes every 2 seconds. The alarms are displayed
in conjunction with an icon showing the type of alarm in question (information, active delay, danger).

Description
Inconsistent parameters or inconsistent data between key plug and pro-
tection release
Prealarm condition of the specified protection. Example: "Prealarm L"
Iw threshold exceeded
Contact wear prealarm (>80%)
Incorrect date that must be programmed (new protection release that has
been off for over 48h)
"Open/closed" circuit-breaker state inconsistent or incorrect
Frequency measured beyond declared range (<-10% or >+10%)
Internal temperature of protection release off-range (<-25° or >85°)
Time delay condition of the specified protection, which can conclude with an
opening command transmitted to the CB. Example: "OV time delay"
Alarm for contact wear (=100%)
Alarm for measured harmonic distortion (form factor>2.1)
Alarm of the specified protection, of which the trip function has been disabled.
Example: "Gext (TRIP OFF)"
Alarm of the specified protection, of which the trip function has been disabled
or if the trip is activated but the CB is already open Example: "Alarm RP"
Load control alarm. Example: "Load LC2"
Alarm of the specific current sensor (disconnected or faulty). Example:
"sensor L3"
Trip Coil disconnected or faulty
Rating plug absent, disconnected, faulty or of a model superior to the lu
Error following an incorrect installation procedure or failure to install
Power factor module lower than set limit
Inverted cyclic direction of the phases (in conjunction with the voltages)
Error in local bus owing to absence of communication or error
