1.1General
PowerSig M560 multifunction transducer is a complete
measuringsysteminasingle100mmDin rail mount case.
Measuring Phase Volts, Phase Current, Frequency, Active
Power, Reactive Power, Energy and Demand. The M560
provides up to 3 analogue outputs and the options of
RS485modbus outputand pulsed output.

The M560 units are fully programmed by the factory and
no further programming is necessary. If the RS485 option is
ordered, the user can reprogram parameters to individual
requirements, such as the voltage and current ratios, relay
output,demandtimes aswellasassigndifferentparam-
eters to the outputs. These programming operations are
coveredinthismanual.
The M560 uses a high speed microprocessor and analogue
to digital conversion circuitry. Each phase current and
voltage is measured continuously and all other parameters
are derived from these measurements in the software.
Voltageand current measurementsare true RMS.
1.2ParametersMeasured
The M560 Measures the following parameters :
M560AT~1.PM5 01/08/101, 12:513

Export Reactive Energy (VAr.h), Power Factor per phase
(P.F.), System Power Factor (P.F.), Amp Demand, Watt
Demand, V A Demand, Maximum Amp Demand,
Maximum Watt Demand, Maximum VA Demand.
1.2 Memory
All data including energy registers, current and voltage
ratios and the calibration data is stored in a non volatile
e2prom. In power down (power loss) conditions all the
information is retained. The e2prom requires no battery or
other circuitry to maintain the stored data.
1.3RelayOutput(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
section2.15.1).
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).

M560AT~1.PM5 01/08/101, 12:514

1.4Communications(optional)
The M560 has the option of providing RS485 output of all
measuredparameters.
The serial port option enables remote reading and
programming of the M560 via a host computer, laptop etc.
The RS485 uses the Modbus protocol allowing multi-drop
with up to 32 M560s connected in parallel. The RS485
Modbus protocol allows the M560 to be used with PC,
PLC, RTU, Data loggers and Scada programs.

1.5LEDindicator
The red LED on the front of the M560 serves three
purposes:
LED continually illuminated means that the power supply
is o.k.
LEDilluminated and flashing every10 seconds means that
the power supply o.k. and the M560 is communicating
correctly.
LEDilluminated andflashing everysecond and2 flashes
every 10 seconds means that the power supply o.k. and
that unit is communicating correctly, but there is no input

network the M560 will automatically detect and configure
itself to the network's settings. These settings can be locked

2.14Programming of nominalvoltageand current inputs
andratios.
The program allows the user to program the nominal
voltage and current inputs and ratios. Please note the ratios
can be changed as long as the secondary (the input to the
M560) stays as shown on the data label which is on the side
of the product. For example if the M560 had been set by the
factory to have a C.T. ratio 200/5A and the change required
was for the input C.T. ratio to be 500/5A this can be
achieved by program changes. But if the change required
was for a C.T. ratio 500/1A then the unit would have to be
returned to the factory or distributor to have the internal
C.T. changed from 5A to 1A. The same applies to the
voltage if the M560 input voltage is 110 Volts L.L then an
external voltage transformer ratio can be programmed as
long as the nominal input to the M560 stays at 110V L-L

2.15.3 Selecting Relay Divisor
This allows the user to set the relay to pulse every 1, 10 ,
100 or 1000 counts. i.e. If the divisor is set to 1 every time
M560 registers and stores 1 count relay the pulses once. If
set to 100, the relay only pulses once after M560 has
registered and stored 100 counts. The M560 always
registers and stores the number of counts regardless of what
the relay divisor is set to. i.e. If the kilowatt consumption
was 500 kW per hour and relay divisor was set to 100 you
wouldget5pulsesanhour.
