Fig. 5 Serial interface
1. Electrical connection without a protective conductor PE is not
permissible.
2. The drive of your RS200 is fitted with a frequency converter. To
fulfil the EMC directive this is fitted with a line filter and shielded
cables to the motor. If your RS200 includes a fault-current
protective system, fault throwing may result through the antiinterference wiring of the frequency converter when this is
switched on (switching on takes place each time the milling
chamber hood is closed). This can occur without there being a
fault on your RS200 or your mains installation.
According to state of the art selective a.c.-d.c. sensitive faultcurrent protective systems are recommended for such cases. The
tripping current must be adequately dimensioned since
capacitive compensating currents occurring only for a short time
(shielded cables, line filter) when switching on can easily cause
fault throwing.
Under certain circumstances it may be necessary to operate the
RS200 without a fault-current protective system. In this case,
however, it should be checked whether this is inconsistent with
the local regulations of the electricity supply company or other
applicable institutions or standards.
Serial interfaces

Before starting the RS200
The milling cup clamping device has proved itself for
many years, and is easy and reliable to handle. In order
to guarantee safety of the operator and a long service
life of the machine components the milling cups must
be clamped carefully.
Please remember that the RS200 is a milling machine
with a very high power input into the milling material;
therefore the milling cups must be fixed properly.
Before starting the machine ensure that the milling set is
clamped.
Milling set can be ejected; danger of injury and damage
to equipment.
Do not use the grinding jar if it has 4 identical 13-mmdiameter boreholes on the bottom.
These grinding jars may only be used in RS200 devices that
do not have a change index after the serial number. This
means that if a change index (e.g. xxxxxxxxx-F) is specified
behind your device’s serial number, you may not use the
older grinding jar described in the above.
Older grinding jars with 4 identical boreholes on the bottom
(13mm) can be reworked free of charge.
The RS200 is suitable only for milling sets with a nominal
volume of 50 – 250 ml.
These are available in the following materials:

The milling set to be used is determined by the sample
volume and max. charged grain size. Selection of the milling
set material depends on the degree of hardness of the milling
material and the effect of possible abrasion on the
subsequent analysis.
If the filling level of the milling set is too high or too low the
milling result will be impaired and damage (wear increase) to
the milling set can result.
Please take necessary measures, depending on the dangerous
nature of your milling material, to avoid danger to persons.
When removing and opening hot milling cups it is essential to
wear protective gloves.
Danger of burning the hands.
Do not subject milling cups with ceramic inserts to sudden

The service menu is divided into four sub-menus:
SERVICE INSTRUCTIONS
Service instructions are filed here in the form of a checklist which is intended to facilitate effective,
regular service and to improve the operating state of the machine. See also the section General /
Maintenance.
SERVICE INTERVAL
An individual service interval can be seet here, according to the environment of the machine. After this
time the operator is required to have the machine serviced. The time to be set is related to the total
sum of milling times (times between START and STOP). A time between 1 – 99 hrs can be set. If the
environmental conditions are rough we recommend that the works preset time is reduced.
OPERATING HOURS
The milling hours are counted, i.e. the total sum of the times between START and STOP. These times
cannot be manipulated.
OPERATING SOFTWARE
The operating software version can be interrogated and, if necessary, updated. When required please
contact your Retsch distributor.
If you have accidentally got into the menu and jumping back into the previous menu is not possible,
switch off the unit at the main switch and restart.

After 15 minutes inactivity of the unit (times after a STOP command) the stand-by monitor switches on
automatically.
By pressing one of the buttons, or touching the setting knob, the stand-by monitor disappears without carrying
out the command which has been made.
If you were in a sub-menu when the stand-by monitor was activated, you return to this selection window
automatically.
The stand-by monitor cannot be set and cannot therefore be switched off.

General
Do not clean the RS200 with running water.
Danger to life through current surge.
Use only a cloth moistened with water. Solvents are not
permitted.
To ensure that your RS200 will function reliably, the following
maintenance work should be done from time to time, but at the
latest every month :
Check that roller 1 in the locking bolt moves easily. If it
doesn’t, oil it, e.g. with sewing machine oil.
(Fig. 17 Locking bolt)
Clean magnets 2 in the locking bolt.
To ensure that the grinding jar can be clamped and
released safely, it is essential that the clamping
mechanism can move easily. It must be checked and
cleaned every day and lubricated when necessary.
(Fig. 17.1 Locking bolt)
To ensure that the housing cover on the RS 200 can close
reliably, it is essential that roller 1 in the locking bolt can move
easily.
Caution! Due to capacitor discharging at the frequency converter
the device conducts voltage for up to 3 minutes after the mains
plug has been disconnected.
