Setting the set-point limits
The minimum and maximum set-point limits provide safety for the equipment. These
limits should be set before starting temperature control and when changing the thermal
fluid in relation to the temperature range of the thermal fluid.
The maximum set-point limits the set-point input of the outlet temperature. The
minimum set-point protects against viscosity or freezing of the thermal fluid with low
temperatures. The set-point input is only possible in the band between maximum and
minimum set-point limit.
Select the
Set-point limits
option from the
Main menu
. Enter the required minimum /
maximum set-point using the rotary knob /key (61), and then confirm it by pressing the
rotary knob / key (61).
Check the value of the minimum and maximum set-point for every system change, in
particular if the thermal fluid is changed.
Entering a set-point
Select the
Set-point
option from the
Main menu
. The new set-point can be chosen, and
confirmed using the rotary knob (61). The value of the set-point is limited by the
current minimum and maximum set-point limits.
The following is true:
minimum set-point <= set-point <= maximum set-point
If an attempt is made to enter a set-point outside these limits, then a warning message
will be shown on the display (60) and the set-point will not be accepted.
Starting CC Temperature control
After filling and fully air purging, the temperature control can be started. Choose the
menu point
start&stop
via the
Main menu.
Confirm and activate by pressing the rotary
knob (61). Alternatively, one may press the function key T3 (65) to start the
temperature control.
