1.1 General

PowerSig M560 multifunction transducer is a complete
measuring system in a single 100mm Din 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
RS485 modbus output and pulsed output.
Power Systems :-

Product code
1 Ph. M560-AT1
1 Ph. 3 Wire M560-AT1-3
3 Ph. 3W unbalanced load M560-AT4
3 Ph. 4W unbalanced load M560-AT9

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, demand times as well as assign different param­eters to the outputs. These programming operations are
covered in this manual.
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.
Voltage and current measurements are true RMS.

1.2 Parameters Measured

The M560 Measures the following parameters :
Phase Voltage (V), Phase Current (I), Frequency (Hz),

Active Power per phase (W), System Active Power (W),
Reactive Power per phase (VAr), System Reactive Power
(VAr), Apparent Power per phase (VA), System Apparent
Power (VA), Import Active Energy (W.h), Export Active
Energy (W.h), Import Reactive Energy (VAr.h),

3

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.

1.3 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).

4

1.4 Communications (optional)

The M560 has the option of providing RS485 output of all
measured parameters.
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.

Software is available for programming and displaying
parameters. Contact your local distributor for a free copy
or visit our website www.multitek-ltd.com

1.5 LED indicator

The red LED on the front of the M560 serves three
purposes:

LED continually illuminated means that the power supply
is o.k.

LED illuminated and flashing every 10 seconds means that
the power supply o.k. and the M560 is communicating
correctly.

LED illuminated and flashing every second and 2 flashes
every 10 seconds means that the power supply o.k. and
that unit is communicating correctly, but there is no input
measuring voltage signal.

2.0 PROGRAMMING

If the unit has not been provided with a communication
option this section is not relevant, please move to section 6
installation.

2.1 Using the M560 Software Monitor 95.
(M560 Software Monitor 95 can be obtained from your
Multitek distributor, or the Multitek website
www.Multitek-Ltd.com)

2.2 Open the Monitor95.exe file and the following screen
will be displayed.

The following functions displayed relate to the PC or
master node and are set by default to the following
settings, Response time = 300mS, Node = 1, Baud Rate =
9600, Parity = None. It may not be necessary to alter the
above settings but the communication port has to be
opened by clicking on start and following section 2.5.

To program different CT & VT ratios, demand times, etc.
the General Pass Code must be entered. The General Pass
Code is 080453. This is general pass code and is only
applicable to Multitek M560 software. Pass Codes
necessary for use with other software are listed in Section 4
page 45 of this manual.

2.13 Communications Lock.
Response Time, Node Number, Communication Port, Baud

Rate and Parity are dependant on the system and PC etc.
that is being used. When connected to an existing Modbus
network the M560 will automatically detect and configure
itself to the network's settings. These settings can be locked
into the EEPROM of the M560 to prevent unnecessary
hunting. For a more detailed explanation of this facility see
help file in the Monitor95 Software.

2.13.1 To Lock communications setting into the M560
EEPROM.

ACTION : Click Lock
Button.
COMMENTS :
M560 communication port
will be locked onto existing
network settings.

Button.

COMMENTS :

2.14 Programming of nominal voltage and current inputs
and ratios.
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

For example if the input was originally programmed for

6.6kV/110 and a V.T. of 11kV was required then this change
could be achieved through software. (See example below)

2.14.1 Changing VT ratio.

2.15 Pulsed Output (Pulsed output is an option. If the unit

does not have this option please proceed to section 2.16)
The M560 measures and displays W.h Import & Export,
VAr.h Import & Export, VA.h, A.h. Any of these parameters
can be assigned to the output relay to give pulses
corresponding to which ever parameter is selected.

2.15.1 Selecting Parameter to be assigned to relay for

pulsed output.
