1.5.3 CA 443
Ce dispositif permet de mesurer la consommation de courant, la déviation de phase et la tension
d'alimentation pour une pompe ou une station complète.
If pump is operated from a frequency converter, special precautions are required.
The high electric noise level can distort electrical readings, especially phase timing readings are
sensitive to switch transients from frequency converter.
Turn off all phase related alarms and dry run detection in PC 441 and ensure PC 441 firmware ver-
sion is V.1.42 or later
Normal current transformers operate from 45-60 Hz and must be placed on mains line input to
frequency converter.
Use only mains phase (voltage) missing alarm for pump protection (blocking).
To avoid conducted electrical noise in cabinet, follow best practices and manufacturer EMC compli-
ance recommendation when installing frequency converters. Use shielded cables. Ensure mains
and motor cables are separated from signal cables in cabinet.
General precautions:
If CA 443 for P1 also is used for mains monitoring, L1, L2 and L3 voltage inputs must be connected
before pump circuit breaker.
