Operation

Start-up

Stirring

• Set the speed using the rotating / pressing knob (D)
  The set speed value is shown on the right of the display
• Press the rotating / pressing knob (D) to start the stirring function

Heating

Setting the safety temperature limit:
The maximum achievable heating plate temperature is restricted by an adjustable safety temperature limit. Once this limit has been reached, the device stops heating.

Notice!
The denominated temperatures should always refer to the center of the heating plate.

The safety temperature limit must always be set at least 25°C lower than the flash 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: see section "Technical data".

After switching on the device, the safety temperature limit can be adjusted using a screwdriver. Do not turn the setting screw beyond the clockwise or anticlockwise stop. This will cause irreparable damage to the potentiometer.

Functional test: safety circuit switch-off

• Heat the device to a temperature of over 100°C.
• Set the safety temperature limit as far to the left as possible.
• The display will show: Er25

Start heating:

• Set the safety temperature limit (see "Setting the safety temperature limit")
• Set the target temperature using the rotating / pressing knob (C)
  The set temperature value is shown on the left of the display
• Set the temperature control mode (see "Temperature control mode")
• Press the rotating / pressing knob (C) to start the heating function

General information for heating:

• The set and actual temperature values are shown permanently on the display
• When the heating function is switched on, the "Heating function activated" symbol is displayed
• When the device is switched off while the heating plate temperature is higher than 50°C, the display shows "Hot!" and the actual temperature value is shown, even if the device is switched off

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 function:
If the test current is interrupted because of eg breakage of contact thermometer or falling out of the cable plug, the heating cuts off.

Settings:
For detailed instructions for settings and limit values, please refer to the operating instructions of the device you are connecting.
The desired medium temperature can be adjusted on the contact thermometer. The required surface temperature of the heating plate can be selected with the rotating / pressing knob or button.
Adjusting the temperature of device to the maximum adjustable temperature will result in the fastest possible heating time. However, the medium temperature may fluctuate to values above the set-point temperature on the contact thermometer. By adjusting the rotating / pressing knob or button to approximately twice the set-point value of contact thermometer (with a setpoint 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.
The maximum heating plate temperature is limited to the adjusted safety temperature limit in the event of a control circuit malfunction. (See "Setting the safety temperature limit")

Menu structure

Menu details

Operating mode

Mode A:
All settings will be stored if the device is switched off or disconnected from the power supply. The stirring and heating functions will be set to OFF when the device is powered on. The safety circuit can be set or modified. When the power supply switch is switched on, A is displayed.

Mode B:
All settings will be stored if the device is switched off or disconnected from the power supply. The stirring and heating functions will be set to ON or OFF when the device is powered on, depending on the previous status of the device. The safety circuit can be set or modified. When the power supply switch is switched on, B is displayed.

Mode D:
When switching the device on, the safe temperature has to be confirmed by pushing one of the rotating / pressing knobs.
During operation, in mode D the device behaves the same as in Mode A with the exception that:

• The temperature / speed setting must be confirmed by pressing the rotating / pressing knob. To change the temperature / speed setting, turn the rotating / pressing knob until the desired value appears.
• The new value flashes for 5 seconds on the display. Confirm the new temperature / speed setting by pressing the rotating / pressing knob, otherwise the temperature / speed setting value will skip back to its previous value.

Temperature control mode

When using an external PT 1000 temperature sensor, you can choose below control modes:

PID mode:
Good control results, minimized overshooting, slow rise in temperature.

2P-mode (two-point controller):
Maximum heating rate, increased overshooting.

PI mode:
Good control results, for some of the heating blocks.

Intermittent mode / Rotation direction

Intermittent mode:
In intermitted mode, the stirring function is interrupted cyclically. 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 appears on the display ( )

Rotation direction:
You can select the continuous rotation by setting the time to 00:00:00 via pushing the rotating / pressing knob (D). Afterwards the rotation direction can be selected by turning the rotating / pressing knob (D).
Alternatively to continuous stirring, you can set the direction of rotation reversal. 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.

Temperature unit

The menu item "Temperature unit" allows the user to select the desired unit between "°C" or "°F" for displaying the temperature.

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.

Notice!
You can set a value from 05 to 30 min for this time limit depending on the application. If time limit is set to 0 min, the "Er05" detection is disabled.

This function will only be active if:

• sensor temperature is < 50°C
• difference between target temperature and sensor temperature > 5 K

Timer expired

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.

Switching off the stirring function can lead to a delayed boiling

Safe / Visc

Once the "VISC / SAFE" has been set to "VISC", the viscosity trend value 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 stabilized to the target speed, the viscosity measurement is started at 100% The change in the viscosity is then shown in %.
The value can always be reset to 100% by pushing the „Menu" button for 2 seconds.

Notice!
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".

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")

Probe calibration

In order to use tolerances to limit temperature deviations, the user can calibrate the temperature sensor in conjunction with the device.

2-point calibration:
Calibration using two temperatures

Notice!
For calibration, select a suitable stirring speed for the application.
