Default Configuration
Note: Most of the default configurations that are programmed at the factory can be reprogrammed.

Output Switches - The two output switches can be dedicated to any combination of setpoints. The
default configuration is listed in Table 2. Each output switch can be configured to be normally
open or normally closed. The default configuration is normally open. Each switch can also be
configured for latching or nonlatching. The default configuration is nonlatching.

Note: The scanner's filter will delay the reaction of the output switches.

The output switches will react if the temperature is exceeded for a selected setpoint. A hysteresis
of 5 °C (10 °F) prevents the output switches from rapidly turning on and off when the temperature
is near the threshold. The hysteresis is also a factor when the temperature falls below the setpoint.

The output of a nonlatching switch is automatically cleared when the temperature falls below the
setpoint and the hysteresis.

3516C Generator Set SBK00001-UP(SEBP4371 - 21) - Documentation Página 13 de 15

Latching output must be cleared by the operator. The operator must press the "RESET" key for
approximately three seconds until "RESET" is displayed.

"SETPOINTS ACTIVE W/ARM TEMP & TIMER" - This parameter is a condition for
arming of the setpoints for the alarm conditions.

All of the setpoints for the alarms can be configured to be armed by the input for engine rotation
only. The circuit for the input for engine rotation must be open in order for the scanner to detect
alarm conditions.

The setpoints for the alarms can also be configured to be armed by the arming temperature and the
start-up timer ("SETPOINTS ACTIVE W/ARM TEMP & TIMER"). For more information, refer
to Systems Operation, "Start-up Sequence".
