change in level is detected. If Auto is not enabled, the instrument will not update the display

until the next sample time, however the display will flash indicating that the level has

changed. This is done for those instances where sensing air is limited or levels may be

changing due to vessel rolling. Selecting Fast will cause the LevelCom 100 to continuously

and rapidly update the display. This mode should only be used in conditions requiring close

monitoring of tank evolutions (e.g. monitoring of overfill standpipe during bunkering

operations).

Outputs

LIGHTS refers to the LevelCom 100 front panel alarm lights. If selected, the High Alarm LED

will activate on Hi-Hi and Hi alarms. Similarly the Low Alarm LED will activate on Lo Lo and

Lo alarms. Horn is an optional front panel mounted piezoelectric alarm horn that will activate

on the selected alarm points.

If Latch is selected, the lights and/or horn will remain activated until the operator presses the

ACK button. If Latch is not selected, the lights and/or horn will automatically clear once the

alarm condition has passed. The optional relays (1&2) can be configured to activate remote

high or low alarms, to perform control functions or to indicate a failure in the LevelCom 100 or

in the sense line system.

Alarm Setpoints (In Display Units)

Using the selected Display Units, establish the alarm setpoints and hysteresis. Hysteresis is

the distance the level must travel to automatically clear the alarm. For example, if the

LevelCom 100 is set up to display depth, and the Hi-Hi setpoint is 10' 0.0". With a 6.0"
