Figure 5b. Series OTC25 L Parameters and Default Settings

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.
