1.2 Memory
All data including energy registers, current and voltage
ratios and the calibration data is stored in a non volatile
e
2
prom. In power down (power loss) conditions all the
information is retained. The e
2
prom requires no battery or
other circuitry to maintain the stored data.
1.3 Relay Output (optional)
The relay output provides a pulsed output corresponding to
consumption Watt hour import or export, VAr hour import
or export, A.h or VA.h consumption. The relay can be
assigned to any of these parameters (see programming
section 2.15.1).
The M560 automatically calculates the pulse rate and
whether the units are W.h, kW.h or MW.h (VAr.h, kVAr.h
or MVAr.h) etc from the nominal voltage and current
inputs.
The relay is a normally open contact.
Pulse widths can be programmed into the M560, between
20 msec and 200 msec in steps of 20 msec. (See section
2.15.2).
