5 Product description
5.1 Function description
This section describes the function of the device.
The booster heater is an auxiliary heater for MAGIO circulators and consists of a
heater unit with two heating elements as well as a control unit.
The heater unit is placed on a suitable bath or a cooling machine instead of the
bath lid. The bath tank must be filled with bath fluid. An external application
connected to the circulator is required, as the bath tank can no longer be used
for temperature control of samples.
The control unit can be placed on or next to the circulator. The heating capacity
of the booster heater is added to the heating capacity of the circulator. The
booster heater communicates with the circulator via the CAN bus interface and,
if necessary, with a connected cooling machine. The status of the booster heater
is indicated by status symbols on the circulator display.
• At up to 33% heating capacity, only the circulator heater is enabled.
• From 33% heating capacity, the booster heater is switched on. Then both
heaters are actuated equally.
• When the booster heater is active, the pump is run at a minimum of 60%
rotational speed.

7.2 Fill device
This section describes what to pay attention to when filling the bath when the
booster heater is put into operation. The procedure takes into account a
connected external application.
The drain valve on the bath or cooling machine is closed.
The circulator is switched off.
1. Switch the circulator on.
The circulator indicates low liquid level alarm after starting.
2. Disable the booster heater in the menu [Install unit].
3. Turn the circulator off at the mains switch.
4. Remove the heater unit.
5. Half fill the bath with bath fluid.
The bath fluid expands with increasing temperature and can overflow.
With decreasing temperature, the low liquid level protection can be
triggered and interrupt the temperature control process.
6. Switch the circulator on.
The removed heater unit must be disabled. Check the status icon on the
home screen of the circulator: the two lowest dashes of the heater icon
must be crossed out.
7. Start the temperature control application.
The pump starts.
8. Watch the level indicator and, if necessary, adjust the level by refilling or
draining.
Once the working temperature has been reached and the sample inserted,
the level of bath fluid in the bath tank should cover the heating coil of the
heating circulator or the cooling coil of the cooling machine.
9. When the required fill level has been reached, place the heater unit in the
bath opening.
10. Enable the booster heater in the menu [Install unit].
The unit is filled with bath fluid.

Initial operation
19
7.3 Set high temperature safety function
Before each new temperature application, the temperature must be set for the
tank and internal reservoir high temperature cut-off. Set a value that is at least
25 K below the flash point of the bath fluid being used. The surface temperature
of the bath fluid must not exceed the flash point at any time. An alarm is
triggered when the set value is exceeded.
