Operation
5 Operation
This chapter contains instructions on operating steps that
are usually required during normal operation. Instructions
on further settings can be found in the chapter “6 Extended
configuration” on page 22 .
5.1 Commissioning
You can start commissioning as soon as iFerm Nano Tank is
properly connected to the tank and the cooling system.
Attention! - First commissioning
When iFerm Nano Tank is commissioned for the
first time, the factory preset values apply, see
“8.1 Technical data” on page 27 . Change these as
required before you start a process.
¨
Switch on the power supply for the system in which
iFerm Nano Tank is installed. The display switches itself on
and shows the actual and target temperatures.
The connected valve moves into the position obtained
from the current difference between the actual and target
temperatures.
In Cooling mode this means, for example:
–
Actual temperature > target temperature: Valve opens.
–
Actual temperature < target temperature: Valve closes.
¨
Test the function of the valve by setting another target
temperature. The following example applies to Cooling
mode (message OUT2 ):
–
Increase the target temperature to the extent that the
valve must close. There should then no longer be any
detectable flow at the tube.
–
Reduce the target temperature again to open the
valve.
