R-DPA96 A/AN - R-Module 7 (Memory)
154
RUDOLF - Ref. : 876 588 A
PRESENTATION
This optional module must be connected to the
R-DPA96 A/AN
(ref. 4825 0A40, 4825 0A41, 4825 1A40, 4825 1A41). It offers
the following functions via the RS485 JBUS/MODBUS com-
munication interfaces :
• 31-day storing of P+, P-, Q+, Q- with a 10-minute internal /
external synchronisation signal. This signal can be set to 5,
8, 10, 15, 20, 30 and 60 minutes. Storing of the above values
can be done over a 62-day period if saving a single active or
reactive power value.
• Storing the last 10 date-stamped alarms (date/hour, dura-
tion, minimum and maximum values).
• Storing the last min./max. instantaneous values for 3U, 3V,
3I, In, F, ΣP+/-, ΣQ+/-, ΣS, THD3U, THD3V, THD 3I, THD In.
• Stamp-dated storing of the 10 last :
- voltage dips from 5% to 95% of Un (as per IEC 61000-4-
30 and EN 50160) with 10 ms tripping time.
- Transient overvoltage from 105% to 150% of Un (voltage
surges) from a 10 ms build-up time.
- Voltage cut-offs from a value less than 5% of Un.
• Storing of mean values according to synchronisation signal
for 3U, 3V (1 day in 10 minutes) and F (60 days in 10
minutes).
