2. INTRODUCTION
2.1. PRODUCT PRESENTATION
The M1 and M3 display units allow making dimensional control using 1 or 2 air
gauges. Depending on the version it is possible to make simple measurement (with
one air gauge), or display 2 characteristics on the screen and can make static
measurement or dynamic (Max, Min, Max-Min…)
The M1-M3 can be connected to a PC thanks to its RS232 or USB connection.
A footswitch can be connected in order to transfer measurements.
The M1 / M3 displays for air gauges requires a minimum of 2 masters for calibration.

Air preparation unit :
It is mandatory to use a
precision regulation system,
otherwise the measurements
will not be stable.
We can supply the adapted
air preparation unit from SMC,
including stop valve, filter and
regulator + precision
regulator.
The precision regulator must
be adjusted at 3 BARS
(0.3MPa)
N/A
For M3 displays.
It allows to divide the 8mm
tube at the output of the air
preparation unit into 2 tubes
of 6 mm adapted for the
connection on the M3 input.
N/A
Soft polyurethane tubes
6*4mm :
The M1 / M3 are fitted with 2
connectors for air tube with
6mm external diameter and
4mm internal diameter.
We advise to use soft
polyurethane tubes from
SMC, because their flexibility
prevent the display to knock
over due to the pressure of
the tubes on the table.

The optional MB-RL module is
Fitted with 2 independent relays min and max, free of
potential that indicate the position of the measure
according to the part tolerances. The module is also
fitted with 6 inputs allowing
remote control display.
This MB-RL module is wired exactly like the #24136

The following table shows some frequent cases to define which restrictor will be the
most applicable to your application.
If you order a turnkey solution at Bowers, we will deliver the display with the
applicable restrictor. But if you want to use the M1 / M3 display together with your
existing air gauge. Alternative restrictor may be required.
It is advised to contact Bowers for advices or confirmation around this subject.

Cabling with by-pass nozzle (integrated restrictor)
Some air gauges are delivered with a by-pass nozzle (or integrated restrictor). It
means that the restrictor is integrated inside the air gauge itself, and there is no need
to install it on the display. NO RESTRICTOR ON THE DISPLAY.
This configuration allows to have a faster the reaction time and makes the installation
easier by removing the need to choose the adapted restrictor.
If you order a turn key solution at Bowers, it will generally be delivered according to
this principle.

2.3.10. MINI-USB connector
The mini-USB connector has 2 functions
1. Power supply through a wall mounted transformer. This transformer supplies a
regulated 5V/1A DC voltage.
2. Measurement transmission. If you connect your M3 to a PC, the PC will detect
and install automatically the M3 as a standard USB keyboard with the standard
drivers of your operating system (Windows, Mac OS etc..). When you send the
measurement, the value will be written on your PC screen where your cursor
is, in the same way as it would have been typed with a keyboard.
Message that appears when the M1/M3 has been correctly installed:
2.3.11. The 24VDC connector
It is advised to use this power supply when the M3 is panel mounted.
Using this power supply instead of the mini-USB will deactivate the ON-OFF switch.
Therefore, when the M3 is powered, it will start automatically.
2.3.12. The USB stick connector
It is possible to save measurements on a CSV file.
In this case the display must be set the following way:
ConfigurationTransferUSB key
Then once the user either press on the « PRINT » button of the measuring screen or
on the footswitch, one line will be added on the CSV file. (a « output.csv » file is
created when the operator transfers the data for the first time). When the USB stick
has been correctly detected, a USB logo will appear on top bar. If the USB stick is not
connected when the operator transfers the measurement, an error message will pop
up. USB sticks with partitions are not supported.
2.3.12. The footswitch connector
