6 Set-up and Operation
6.1 Intended Use
The R 100C / R 100CL / R 100CT is designed for use in chemical and biological laboratories
of industrial enterprises, universities and pharmacies. It is suitable for stirring and mixing of
liquids from medium to high viscosity. For correct use the device must be fixed to an
appropriate stand.
To ensure maximum service life, observe the specified ambient conditions (temperature and
humidity) and ensure that the instrument is not exposed to a corrosive atmosphere.
The device is not suitable for permanent use
Use a stirring shaft protector
(Part No. 20618-0060) to provide protection
against injury when working with the unit.
Attach the fastening rod (H) of the shaft
protector (M) in front of the chuck to the stand;
e.g. use cross over clamp part no. 60492-0000)
to fix the stirring shaft protector. Now bring the
pockets (K) to the screws (J) and turn the stirring
shaft protector to the left to the limit stop.
The screw (L) is used to adjust the length of the
stirring shaft protector.
Check that the stirring shaft protector is held in
position securely prior to each use and also at
regular intervals. The position of the stirring
shaft protector must only be adjusted when the
unit is stationary and the power supply is
disconnected.

7 Safety Functions
7.1 Rotor stuck detection
If the torque increase versus time exceeds a certain limit the unit will assume that the rotor
was suddenly blocked and will switch off immediately.
Cut-off limit sensitivity can be adjusted in the Set-up menu (Cut off limit)
7.2 Overload protection
If the torque or power drawn from the stirring motor exceeds the allowed range, the unit will
automatically reduce the motor speed until the torque is reduced to the allowed range. If this
happens the LED Load (6) is switched on.
As long as the Load LED (6) is on, the motor is not able to hold the set motor speed.
7.3 Overtemperature protection R 100C
If the temperature inside the unit exceeds the maximum operating temperature, the unit will
automatically reduce power output (speed and torque) in order to get back to a safe
operating point ( = fold back characteristic). This prevents the unit to be destroyed by
constant overload operation. This overload condition is also signalled by the red ´Load´ LED
(6).
Furthermore a cooling fan (11) on the rear side of the instrument is automatically switched on
if required.
If the temperature inside the R 100C exceeds 70°C by any means, the unit will shut down
immediately. This safety feature is fully "redundant". The unit either shuts down if the
microprocessor measures a temperature higher than 70°C, or if the thermo-switch (inside the
R 100C) detects a temperature higher than 70°C.
Important Note:
Before re-starting the unit after cooling down, switch it off and then on again by
using the on/off button.
7.4 Overtemperature protection R 100CL
If the temperature inside the unit exceeds the maximum operating temperature, the unit will
automatically reduce power output (speed and torque) in order to get back to a safe
operating point ( = fold back characteristic). This prevents the unit to be destroyed by
constant overload operation. This overload condition is also signalled by the red ´Load´ LED
(6).
Furthermore a cooling fan (11) on the rear side of the instrument is automatically switched on
if required.

7.5 Over-temperature protection R 100CT
If the temperature inside the unit exceeds the maximum operating temperature, the unit will
automatically reduce power output (speed and torque) in order to get back to a safe
operating point ( = fold back characteristic). This prevents the unit to be destroyed by
constant overload operation. This overload condition is also signaled by the red ´Load´ LED
(6).
Furthermore a cooling fan (11) on the rear side of the instrument is automatically switched on
if required.
If the temperature inside the R 100CT exceeds 70°C by any means, the unit will shut down
immediately. This safety feature is fully "redundant".
7.6 I/O Connector (9-pin SUB-D)
Pinout of the I/O connector
The following signals are led out on the 9-pin SUB-D connector on the rear side of the
instrument:
RS232 control signals
Analogue input (0-10V) for speed override.
Analogue output (0-4V) for recording of process parameters (speed, torque, power)

8 The RS232 interface of the R 100C / R 100CL / R 100CT
The RS232 interface enables remote control of all stirrer functions. In this configuration a
computer can access each connected unit via a sub address (daisy chaining). This address
is programmable for every unit (Setup menu, slave-address).
For daisy-chaining, the transmit line (TxD) of the PC is connected to the receive line (RxD) of
the first unit. The transmit line of this unit is then connected to the receive line of the next unit
in the chain. The transmit line of the last unit in the chain is returned to the receive line of the
PC, which closes the link (ring). You achieve this by using one or more Y cables (PN 60729-
00). For each additional device, you will need a Y-cable, e.g. for 3 devices to be connected, 2
Y-cables are required (see also Chapter 8.6)
For addressing a specific unit in a daisy-chain, each controller carries a so called ´Slave-
address´ which can be any number from 1 to 255. The default slave address is 1.
The slave-address 0 is defined as the general call address on which all controllers will
respond.
The slave-address can be set/changed in the Setup-menu.
A Windows  Software to control a connected unit is optional available.
Parameters of the serial interface (1200-4800,8,N,1):
Baudrate: 1200-4800 Baud (1200 default, see also: Set-up menu)

8.2 Format of an RS232-Command
Each command which is sent to the device must have the format:
ADR , CMDCODE , PARAMETERLIST <CR>

ADR: Slave Address of the unit to execute the command
CMDCODE: Command-code
PARAMETERLIST:1 to 6 parameters separated by commas
CR: The command string must be terminated by
Carriage/Return (ASCII 13)
