4.5.3 Submenu “Cooler/Heater”
A Microdispensing System MDS can be equipped with a heater or a cooling valve. For heating,
you can use a 48 V heater (e.g. Heater MDH-48-BY, order no. 1014231). For cooling, you can use a
flow control valve (e.g. Flow Control Valve FCV-AC 6.0 M12, order no. 1016265).

CAUTION
Danger of burns through high temperatures!
The heater can reach temperatures of up to 180 °C.
• Do not touch this area during operation.
• And afterwards only touch it once it has cooled down.
By using a heater, the dynamical viscosity of the fluid to be dispensed can be controlled. 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.
To reach a certain target temperature takes time. This time is influenced by many different
circumstances, e.g. the outer temperatures.
Fig. 9: Submenu “Cooler/Heater”
All relevant functions of the heater and the cooling valve can be set in this submenu. With
“Cooler” you can reach the submenu for the cooling settings (see paragraph 4.5.3.2, page 31).
INFORMATION
MDC detects the heater and the cooler during start-up
During start-up, the MDC also checks if a heater and/or a flow control valve is connected. The
messages “Heater connected” (or “Heater is disconnected!”) and “Cooler connected” (or “Cooler
is disconnected!”) will be displayed. When a heater is connected, the display switches between
the message “Heater connected” and the message “press enter” (see Fig. 8). You need to press
the [enter]-key to confirm it.
