adjustable safety temperature limit. Once this limit has been reached,
the device stops heating.
Caution! ( )
The denominated temperatures should always refer to
the center of the hotplate.
Warning! ( )
The safe temperature limit must always be set at least +25 °C
lower than the fire point of the media to be processed!
The adjustable maximum heating plate temperature must always
be set at least +15 °C under the set safety temperature limit.
Setting range: [+100 °C] to [max. SET temperature +650 °C]
Factory setting: [max. SET temperature +650 °C]

Start-up 2726 Start-up
/// Controlling the medium temperature limit
using a contact thermometer
The preferable method for controlling the average temperature is with
contact thermometer. After the set point temperature has been adjusted,
this results in a short heating-up time, practically no temperature drift and
only minor fluctuation in temperature.
A 6-pin jack is located on the rear side of the device for connecting the
PT 1000 series, contact thermometer or the contact plug. The electronics of
the devices returns a test current that must flow via connector pins 3 and 5
for the heating plate to heat up.
Safety contact thermometers
Acc. to DIN 12 878 class 2 or acc. Gerstel are connected with a three-wire
cable, the test current flows through the contact thermometer.
Safety function
If the test current is interrupted because of e.g. breakage of contact thermo-
meter or falling out of the cable plug, the heating cuts off.
Contact thermometer without safety circuit
Acc. to DIN 12 878 class 0. The device only heats if the test current circuit is
closed by an electrical connection of the plug pins 3 and 5.
2-wire connecting cables
Connect plug pins 3 and 5 of the device plug.
3-wire connecting cables
Here the test current circuit can also be produced in the terminal
head of the contact thermometer (connect plug pins 2 and 3).
A 3-wire cable with the required bridge is available (accessories).
Settings
For detailed instructions for settings and limit values, please refer to the
operating manual of the instrument you are connecting.
The desired average temperature can be adjusted on the contact
thermometer. The required surface temperature of the heating
plate can be selected with the rotating knob (temperature) or
button.
Adjusting the temperature of device to the maximum adjustable tempera-
ture will result in the fastest possible heating time, but the average tem-
perature may fluctuate to values above the set-point temperature on the
contact thermometer. By adjusting the rotating knob (temperature) or
button to approximately twice the set-point value of contact thermometer
(with a set-point of +60 °C, the temperature of device would be set to
+120 °C), you will reach a good compromise between a fast heating
time and over-shooting the set point. If you adjust the temperature of the
device to exactly the set-point temperature, the medium will not reach
the set-point temperature because some loss of the heat will always
occur between the heating plate and the medium.
If a fault occurs in the control circuit, the maximum heating
plate temperature can be adjusted with the safety temperature
setting screw.

/// Intermittent mode / rotation direction
Intermittent mode
Intermittent mode consists of regular, cyclical interruption of the stirring
function. The run time (0 / 10 sec – 10 min, 10 sec steps) and pause time
(3 sec – 5 min, 1 sec steps) should both be set. When the intermittent mode is
activated, a decimal point in front of the first letter appears on the display (18).
Rotation direction
You can select the continuous rotation. Therefore the time has to be set to
00:00:00 by pushing the rotating knob. (D). Afterwards the rotation direction
(clockwise or counterclockwise) can be selected by turning the rotating knob
(D). Alternative to the continuous rotation, you can set the automatic reverse
rotation function. Then the rotation direction changes after each pause.
In this way the magnetic rod is captured and any liquid still rotating is gradually
slowed down. Then the drive accelerates to the target speed.
/// Beep
The menu item “Beep“ allows the user to turn on / off the sound that occurs
when the timer reaches 00:00:00 or an error message appears.
/// Error 5
Providing safety protection, Error 5 is taken to recognize that the sensor
has not been placed in the medium when the heating is switched on.
Note! ( )
You can set a value from 1 to 30 min for this time limit depending on the
application. If time limit is set to 0 min, the Error 5 detection is disabled.
Caution! ( )
This function will only be active if:
› sensor temperature is < +50 °C
› difference target temperature / sensor temperature > 5
/// Expiration of timer
You can specify the procedure of heating and stirring function if the timer
achieves 00:00:00. Next to the visually / audible information you can decide
independently if the heating and stirring should be stopped automatically if
the timer is expired or should continue.
Caution! ( )
If heating and stirring function is set to stop after timer is expired,
you have to ensure that there is no heat distortion for this application.
If heat distortion is not desirable, the stirring function should continue.

Menu 3736 Menu
/// Safe / Visc
Once the “VISC / SAFE“ has been set to “VISC“, the viscosity trend value (12)
will be shown on the display. The torque trend measurement is used to
deduce the change in viscosity of the reaction medium. The devices are not
designed to measure absolute viscosity. They only measure and display the
relative change in the viscosity of the medium from a starting point specified
by the user.
Once the speed of the motor and magnetic rod in the medium have sta-
bilized to the target speed, the viscosity measurement is started at 100 %.
Consequently, an increase in the measured torque trend is indicated by a
value > 100 % and a reduction in values < 100%.
The value can always be reset to 100 % by pushing the „Menu“ button (E)
for 2 seconds.
Note! ( )
Torque trend measurement only works for a constant set speed for
the duration of the measurement. As a result, intermittent mode
cannot be used in conjunction with torque trend measurement.
The current control variable is saved as the reference 100 % ΔP and shown on
the digital display. The change in the viscosity is then shown in %.
When on the “VISC“ screen, the screen will switch to “SAFE“ if the adjustment
of the safety temperature is activated, during which you may set the safety
temperature and the screen will switch back to “VISC“ once the setting is done,
otherwise it will switch back to “VISC“ after 2 seconds.
/// Factory reset
The menu item ”Factory reset” allows the user to reset all the system
settings to the original standard values set at dispatch from the factory
(see “Menu structure”).
/// External probe calibration
In order to use tolerances to limit temperature deviations, the user can
calibrate the temperature sensor in conjunction with the device. If the
calibration is not set at default (customer-specific settings), the user can simply
reset the calibration. If the calibration is set at default (factory setting), the
user can use below method to calibrate the temperature sensor.
2-point calibration
Calibration using two temperatures.
Note! ( )
Before starting the calibration process, please select an appropriate speed
value according to the application environment. Compare the actual tempe-
rature with a calibrated reference measuring instrument.
