of the fluid and no more than 10 degrees above the upper temperature limit of
the bath.
If the cutout is activated because of excessive bath temperature, power to the
heater shuts off and the bath cools. The bath cools until it reaches a few degrees
below the cutout set-point temperature. At this point the action of the cutout is
determined by the setting of the cutout mode parameter. The cutout has two
selectable modes — automatic reset or manual reset. If the mode is set to auto-
matic, the cutout automatically resets itself when the bath temperature falls be-
low the reset temperature allowing the bath to heat up again. If the mode is set
to manual, the heater remains disabled until the user manually resets the cutout.
The cutout set-point may be accessed within the secondary menu. Press “SET”
and “EXIT” to enter the secondary menu and show the heater power. Then
press “SET” twice to access the cutout set-point.
