CUTOUT
The Cutout menu contains the Soft and Hard Cutout functions of the Product. As a protection against
software or hardware fault or user error, the Product has an adjustable cutout device that shuts off
power to the heat source if the target temperature exceeds a set value. The factory default is
10 degrees above the high limit of the Product. If the cutout is activated because of excessive target
temperature, power to the heat source shuts off and the Product cools. The Product remains in cutout
mode and active heating and cooling are disabled until the user manually resets the cutout. If the over-
temperature cutout is triggered, the Product displays
CUTOUT
above the duty cycle bar graph, which
indicates a cutout condition. The Product remains in cutout mode until the temperature is reduced and
the cutout is reset. The target temperature must drop a few degrees below the cutout set-point before
the cutout can be reset. For safety reasons, the cutout only has one mode - manual reset. Manual reset
mode means the cutout must be reset by the operator after the temperature falls below the set-point.
Note
CUTOUT RESET: If the Product exceeds the temperature set in the soft cutout menu or if it
exceeds the maximum operating temperature of the Product, a cutout condition occurs. If this
happens, the Product enters cutout mode and will not actively heat or cool until the user resets
the Product.
To reset the cutout, the Product temperature must cool to lower than the cutout set-point. Once the
Product has cooled, push
SET PT.
, then
ENTER,
and then
ENTER
again to reset and engage the
Product.
SOFT CUTOUT
The Soft Cutout is user settable. The SOFT CUTOUT parameter can be set to any temperature under
the range of the Product. The cutout should be set within 5 ° to 10 ° of the safety limit of the equipment
being calibrated or used with the Product.
HARD CUTOUT
The Hard Cutout is not user settable. The HARD CUTOUT parameter is a view-only function and
indicates the factory setting for the hard cutout.
