Intended Use
The PMA7500.. or PMA 35.... Series
EX-approved scales from Sartorius meet
all requirements for fast and reliable
paint mixing. The scale housing
is solvent-resistant.
The weighing capacity of the single-range
scales, models PMA7500-X and
PMA7500-X.., is 7,500 g.
The capacity of the dual-range scales,
models PMA7500D-X and
PMA7500D-X.., is 7,500 g and
1,000 g, respectively. Models 35D-X
and 35 D-X000C have a 35-kg
weighing capactiy.
The built-in formulation program lets
you calculate different batch sizes and
measure out any amount as you would
a standard batch. The models that
are equipped with the recalculation
program can quickly recalculate batch
amounts to correct the filling procedure
if a component is overpoured or
underpoured; this saves you having
to make time-consuming calculations.
All models come with a program for
mass unit conversion (toggling between
weight units), as well as a serial data
interface and overload protection.
The PMA scales are ideal for
use as inspection, measuring and test
equipment in quality management
systems.
Built-in application programs
can be used for:
– Measuring in two weight units
– Recalculation
– Calculation
– Initializing the scale automatically
PMA scales meet the highest
requirements on the accuracy and
reliability of weighing results through
the following features:
– Efficient filtering-out of vibration
– Stable and reproducible results
– Excellent readability under any
lighting conditions
– Rugged, durable weighing system
– Approved for use in Category
2 and 3 hazardous areas/locations
(Zones 1 and 2, Class 1, Divisions 1
and 2 hazardous areas/locations)
(models PMA 7200-XCEV3,
PMA 7500-X, PMA7500-X..,
PMA 7500D-X and 7500D-X..
in conformity with EU Council
Directive 94/9/EEC, marked with

Warning and Safety
Information
Improper use or handling can result
in property damage and/or personal
injury. To prevent damage to the equipment, read these operating instructions
thoroughly before using your scale.
Keep these instructions in a safe place.
The manufacturer shall not be held
liable for damage caused by failure
to observe this warning and safety
information or the instructions.
When you use electrical equipment
in installations and under ambient
conditions requiring higher safety
standards, you must comply with the
provisions specified in the applicable
regulations for installation in your
country.
Before you operate your scale in
a hazardous area/location, the scale
must be inspected either by a certified
electrician or under the guidance and
supervision of a certified electrician to
make sure that the scale complies with
the applicable regulations (in Germany,
in accordance with Section 12 of the
ElexV). Determine whether your scale
must be reported to the technical
inspection authorities (e.g., trade
board) in your country. The system must
also be inspected during operation.
The system should be inspected at
intervals which allow for early detection
of the faults which occur as a result of
normal wear and tear, so that they can
be corrected before damage is caused.
In any case, inspection must be
performed at least every three years.
All AC adapters or power supplies
may only be connected to an electrical
outlet (mains supply) (48 – 62 Hz)
with at least for 184 V and no more
than 264 V.
Model 609308-011 and 609308-211
AC adapters (power supplies) are
associated electrical apparatus with
the approval marking [EEx ib] IIC and
II (2) G, and are suitable for installation
only outside a hazardous area
(EC-Type Examination Certificate
KEMA 98ATEX2752 X).
Model YPS03-XDR and YDP03-XGR
power supplies are Category 2 and 3
apparatus that is suitable for use
in Zones 1 and 2 hazardous areas
according to the Council Directive
94/9/EC; EC-Type Examination
Certificate KEMA 98ATEX2771 X).
The explosion-protected equipment
of the PMA Series meets the currently
valid harmonized European standards
in compliance with CENELEC:
EN 50014: 1992
EN 50020: 1994
Install your PMA Series scale
according to acknowledged technical
regulations. You must also comply
with the national laws and safety
regulations of your country.

Follow the instructions below to ensure safe and trouble-free operation
of your scale:
! Make sure that the voltage rating printed on the AC adapter or power
supply is identical to your local AC power rating
! The only way to turn the scale power off completely is to disconnect the
AC adapter or power supply from the scale. Only disconnect the power
cable from the scale after the AC adapter or power supply has been
disconnected from the wall outlet (mains supply).
! Protect the AC adapter or power supply as required by the IP65 standard
(dust-tight and washdown-resistant)
! The casing on the power cable of the AC adapter or power supply
is made of
– rubber (on model 609308-01)
– PVC (on model 609308-21).
All other cables connecting the weighing equipment and peripheral devices,
as well as the wiring inside the devices, are cased in PVC materials.
Chemicals that corrode these materials must be kept away from these cables.
! Use only cabling and extensions approved by Sartorius, as these are made
in accordance with the restrictions on cable lengths imposed by the
capacitance and inductivity values (see the attached certificate of conformity)
and the requirements for electromagnetic compatibility.
! PMA Series equipment may only be operated in an ambient temperature
range from 0 °C to 40 °C (32 °F to 104 °F). Make sure there is sufficient
ventilation to prevent heat from building up in the equipment.
! The equipment must be used indoors.
! The scale is IP40-protected; the peripheral equipment is IP54 or IP65-
protected. Handle the equipment with care as required by the IP protection
ratings. The environment in which it is used must also be protected.
! Connect only Sartorius-approved cables to the data interface port on the
PMA scale. Attach the cable securely to the interface port. To ensure safety,
disconnect the equipment from power before connecting or disconnecting
the data cable. For transmission of data to peripheral equipment located
outside the hazardous area/location, type Z966 (EEx ia) IIC certified Zener
barriers must be installed, such as the Zener barriers made by the Pepperl
+ Fuchs company. The barriers must be installed outside the hazardous
area/location and must be connected to the equipotential bonding
conductor by an equipotential busbar. The barrier can be used in
an ambient temperature range from 0 °C to 40 °C (32 °F to 104 °F).
Connected devices must not be capable of supplying more than
250 V to the barriers.
