This action switches the display to the set temperature function. To return to displaying
the temperature display press the “EXIT” button. If the cutout is still in the over-
temperature fault condition, the display continues to flash “cutout”. The bath temperature
must drop a few degrees below the cutout set-point before the cutout can be reset.
Temperature Set-point
The bath temperature can be set to any value within the range and with resolution as
given in the specifications. The operator must know the temperature range of the
particular fluid used in the bath and the bath should only be operated well below the
upper temperature limit of the fluid. In addition, the cutout temperature should also be set
below the upper limit of the fluid.
Setting the bath temperature involves three steps: 1) selecting the set-point memory, 2)
adjusting the set-point value, and 3) adjusting the vernier, if desired.
Programmable Set-points
The controller stores 8 set-point temperatures in memory. The set-points can be quickly
recalled to conveniently set the bath to a previously programmed temperature set-point.
To set the bath temperature one must first select the set-point memory. This function is
accessed from the temperature display function by pressing “SET”. The number of the
set-point memory currently being used is shown at the left on the display followed by the
current set-point value.
