7.13 Dispensing with a Heater
The Microdispensing System MDS 358X can optionally be equipped with a nozzle heater. One
option is the MDH-48-BY (see Fig. 56). If a heater is connected to the system, the main menu
shows the current temperature (in °C) instead of “Ready”. More detailed information about the
menu, while using a heater, you can find in paragraph 7.13.1, page 77 and paragraph 4.5.3.2,
page 31.

CAUTION
High temperatures, danger of burns
The nozzle heater can reach very high temperatures (e.g. of up to 180 °C with MDH-48-BY). Do
not touch this area during operation. Afterwards only touch it once it has cooled down.
With a heater, you can control the dynamical viscosity of the fluid to be dispensed. For some
liquids, dispensing without heating is impossible. Heating may also be required to ensure a
constant process temperature, or when the dispensing has to take place above room
temperature.
Information how to mount a heater you can find in paragraph 6.2, page 45. You then need the
heater cable 48 V, to connect the heater to the MDC (see paragraph 6.3.3.4, page 53).
INFORMATION
Adjust deactivates heater
If you perform an adjust while the heater is activated, the heater is deactivated automatically.
You have to switch the heater ON again after the adjust, if you need it in your application.
