OTC25 L
Operation
Parameter Descriptions
Default Display
This parameter determines whether the OTC25 L’s display
shows the Limit Setpoint or the actual temperature by
default. Regardless of the selection made here, the operator
can observe the other value by momentarily pressing the
Parameter Key. This will cause the alternate value to
be displayed for five seconds.
Limit Setpoint
The Limit Setpoint determines the temperature at which
the limit output will become inactive, interrupting power to
the process. It is operator-selectable from 32° to 905° F
(0° to 485° C).
Automatic Startup Reset
The automatic startup reset feature allows the limit output to be
automatically reset at startup or to be latched at startup. In the
latter condition, the limit output will have to be manually reset
before the limit output will be activated (relay closed allowing
power to flow to process heaters or coolers)
.
Display Units
This allows the operator to have the display indicate either
degrees Fahrenheit or degrees Celsius.
