The MultiGen is designed to be user friendly and simple to
use. All operations are controlled by the two push buttons
& on the front of the M8**.
All necessary programming is also carried out via the front
two control buttons. The MultiGen units are fully
programmed by the factory and no further programming is
necessary. If required, the User can reprogram
parameters to individual requirements, such as the nominal
current and voltage inputs, relay output etc. These
programming operations are covered in this manual (see
section 4).
The MultiGen uses a high speed microprocessor and
analogue to digital conversion circuitry. Phase voltage and
current measurements are true RMS and the coolant and
oil pressure are measured directly from the engine sender.
Hours Run is measured from the frequency, and DC volts
measured directly from the battery.
1.1 General
The MultiGen M820-GM* series & M830-SM* series are
compact 96 x 96 mm Din case 3 phase generator
monitoring meters, The M820-GM* series measure Volts,
Amps, Frequency, Coolant Temperature, Pressure, Hours
Run, DC volts, and provide relay outputs for temperature
and pressure. The M830-SM series measure Volts Amps
and Frequency.
Power Systems :- Product code
1 Ph. M820-GM1 or M830-SM1
3 Ph. 3W unbalanced load M820-GM4 or M830-SM4
3 Ph. 4W unbalanced load M820-GM9 or M830-SM9

1.2 Memory
Calibration and setup parameters including current and
voltage ratios, calibration constants, sender ranges etc. are
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 Outputs
Two relays are provided as an option. One is a normally
open contact and is used to monitor the coolant
temperature. If the temperature rises above the preset point
the relay contact closes, and on the MultiGen display the
temperature icon flashes.
The second relay is provided to monitor the oil pressure
and this relay is normally closed. If the oil pressure goes
below the preset point the relay closes and the pressure icon
on the screen flashes.
1.4 Communications
The MultiGen has the option of providing RS485
communication.
The RS485 enables remote reading and programming of
the MultiGen via a host computer. The RS485 uses the
Modbus protocol allowing multi-drop with up to 32
MultiGens connected in parallel. The RS485 modbus
protocol allows the MultiGen to be used with PC, PLC,
RTU, Data loggers and scada programs.

2. OPERATION
The MultiGen is designed to be user friendly and simple to
use.
There are only two control buttons on the front of the
instrument. All MultiGens are fully programmed by the
factory. The MultiGen is ready for use once it has been
installed (see section 5), connected to the system that's to be
measured (see section 6) and power applied. The
Right Hand button scrolls down through the Display
Screens and Left Hand button scrolls up through the
Display Screens. See section 3 for display screen options.
The two front control buttons are also used to program the
MultiGen (see section 4).
GENMOM.PM5 20/03/100, 10:325
3. DISPLAY SCREENS
3.1 The MultiGen can be programmed for either single
phase load, a 3 phase 3 wire unbalanced load or a 3 phase
4 wire unbalanced load.
The sequence of the parameters displayed is dependent on
the system that has been programmed into the MultiGen.
3.1.1 When the MultiGen is powered up the following
screens are shown if it has been programmed for 3 phase 4
wire unbalanced (M820-GM9) :-

3.1.3 Screen sequences for the M820-SM series (Note the
SM series only measures Volts Amps & Hz) are as
follows :-
For the M830-SM9 3 phase 4 wire unbalanced load the
sequence will be the same as detail 3.1.1 but without
Pressure, Temperature, Hours Run, DC Volts
measurements.
For the M830-SM4 3 phase 3 wire unbalanced load the
sequence will be the same as detail 3.1.2 but without
Pressure, Temperature, Hours Run, DC Volts
measurements.
For the M830-SM1 Single phase the sequence will be the
same as detail 3.1.3 but without Pressure, Temperature,
Hours Run, DC Volts measurements.
3.2 If the input measuring voltage and current signals are
lost but the auxiliary supply is still present the MultiGen
indicates this by displaying the following.

COMMENTS :
This indicates that measuring
signals are not present but
MultiGen is still functioning
correctly. Check input signal
condition and connections
etc.
