Using MAP Mix Provectus in MM8000 emulation mode

The MAP Mix Provectus (MMP) can be used as replacement for the old MAP Mix 8000 EL
(MM8000) when certain limitations are taken into account. It is however recommended to use
the native operation mode of the MMP if at all possible.
The MMP is a completely different design and there are huge differences in the way it
operates compared to MM8000. The capacity of the new MMP is much greater than that of
the MM8000, this has the effect that the GAS supply must be able to cope with the higher
flows that MMP typically uses. The final flow out of MMP depends of the mixture setting, i.e. if
using 50% / 50% mix on a 2-gas MMP you will get 1000L/min out. Due to the high output flow,
the filling will be much faster than with MM8000.
In MAP Mix Provectus devices with firmware V1.1.0 and below this cannot be limited.
Firmware V2.0.0 has build in menu to reduce the maximum flow out (regardless of what is
possible for the mix shown), use this setting to avoid overshoot in pressure while filling tank.
To enable that mixer runs flawless, installation must ensure that capacity for each gas is high
enough and that restrictions in the gas lines do not influence on the pressure and flow.

the tables on page 74
In general terms there are three ways to use MMP in MM8000 mode:
MMP emulating MM8000 using PBI protocol interface on COM1 (controlled from packaging

machine, PLC or PC)
MMP emulating MM8000 using analogue control voltages to select mixtures. Typically

supplied from PLC DAC.
MMP emulating MM8000 attached to CMV-2

The MixSet program used with MM8000 can also be used with the MMP mixer to configure
buffer tank pressure and select between analogue control modes. It can also be used for
debugging during setup, to stop/start the system and select mixtures.

MMP emulating MM8000 using PBI protocol (PSIP) interface on COM1

To setup the MMP for MM8000 mode, first use the PuTTY terminal program connected to the
mixers COM2 port. If you have a mixer with user interface you can set the parameters from the
General setup menu.
Login as Supervisor (0000) and select General setup -> Mixer configuration.

In Mixer mode select the MM8000 emulation mode you want to use:

- 2-gas mixers can be set to CO2/N2, N2/O2 or CO2/O2
- 3-gas mixers can only be set to 3 gas mode (N2/CO2/O2)
- You can NOT assign GAS type in MM8000 mode as inputs are preconfigured
- Select alarm levels for input gas pressures (per GAS)
In External start/stop select whether the mixer shall be controlled by an external start/

stop signal (24V) or not. The mixer will also start when mixture is changed like the MM8000.
Now the mixer is ready to accept data on COM1 using PBI protocol. You can now attach the
mixer to the packaging machine PLC/PC. The MixSet program of MM8000 can also be
connected to test and configure the mixer.
Notice that pressure alarms will trigger the Alarm relay and will NOT stop the mixer, however if
flow cannot be maintained the Fault relay will be triggered and mixer must be restarted either
by sending stop/start sequence on external control or changing mixture.

for installation requirements and observe the figures in
for minimum pressure drop vs. flow.
