P.33
- Threshold beyond which the integral delay for tripping of the overload alarm is zeroed, causing the immediate intervention of the A08 alarm.
P.34 – P.35
– Data of VTs eventually used in the wiring diagrams.
Parameter table (continued)
P.37 – P.38
- Start and stop temperature for the cooling fan of the panel, expressed in the unit set by P.36.
P.39
- Threshold for generation of alarm A07 Panel temperature too high .
P.40
- Percentage threshold of the residual power of the steps, compared with the original power programmed in general menu. Below this threshold the
alarm A10 step failure is generated.
P.41
- Maximum voltage alarm threshold, referred to the rated voltage set with P.07, beyond which the alarm A06 Voltage too high is generated.
P.42
- Undervoltage alarm threshold, referred to the rated voltage set with P.07, below which the alarm A05 voltage too low is generated.
P.43
- Maximum plant voltage THD alarm threshold, beyond which the alarm A10 THDV too high is generated.
P.44
– Maximum plant current THD alarm threshold beyond which the alarm A05 voltage too low is generated.
P.45
– Maintenace interval in hours. When it is elapsed, the alarm A12 maintenance interval will be generated. The hours count increments as long as the
device is powered.
P.46
– Function of the semi-circular bar-graph.
Kvar ins/tot:
The bar graph represents the amount of kvar actually inserted, with reference to the total reactive power installed in the panel.
Curr act/nom:
Percentage of actual plant current with reference to the maximum current of the CT.
Delta kvar:
bar graph with central zero. It represents the positive/negative delta-kvar needed to reach the setpoint, compared to the total kvar installed.
P.47
– Default measure shown on the secondary display. Setting the parameter to ROT, the different measures will be shown with a sequential rotation.
P.48
– If set to ON, the display backlight flashes in presence of one or more active alarms.
P.49
– Serial (node) address of the communication protocol.
P.50
– Communication port transmission speed.
P.51
– Data format. 7 bit settings can only be used for ASCII protocol.
P.52
– Stop bit number.
P.53
– Select communication protocol.
