9 Alarms
Once the system has been correctly calibrated the system will display the levels of the tanks
in the units desired. The system allows the user to set alarms and alter the damping value.
Each enabled tank sensor may have a minimum and maximum alarm threshold set to it.
When setting the alarm, the threshold level is in the same units as the displayed reading; i.e. if
Tank 1 is in gallons then the alarm value will also be in gallons.
When a tank goes into alarm a system wide alarm signal will be transmitted. All FFD’s will
flash until the alarm is acknowledged.
9.1 To set an alarm
ú Select the relevant tank data on the upper line of an FFD.
ú Scroll Down to ALARMS on the lower line of the FFD.
ú Press ENTER.
ú Select the relevant alarm (minimum or maximum).
ú Press ENTER, the current value/alarm status will be displayed.
ú Press ENTER, the data will flash.
ú Enter the desired value using the scroll keys.
ú Press ENTER to confirm.
After setting the alarm, pressing the PAGE key will return you to normal operation.
9.2 To set an alarm using the PC Utility:
ú Enter relevant values in the maximum and/or minimum alarm boxes for the desired tank.
ú Check the “Alarm Enabled” button.
ú To disable the alarm uncheck the “Alarm Enabled” button.
10 Damping
The damping of a function is the time taken to average the readings - the higher the damping
value the longer the averaging time which leads to less responsive readings. Due to the slow
changing nature of most tanks the damping level is set at ten seconds as a default, this can
be changed if required.
10.1 To adjust the damping:
ú Select the relevant tank data on the upper line of an FFD.
ú Scroll Down to DAMPING on the lower line of the FFD.
ú Press ENTER, the current damping value will be displayed.
ú Press ENTER, the data will flash.
ú Enter the desired value using the scroll keys.
ú Press ENTER to confirm.
After setting the damping value, pressing the PAGE key will return you to normal operation.
Note: While the sensors modules are purging the air from the tubes the reading is unstable.
The TLSP will monitor the system and hold the readings while the purging is being performed.
After purging, normal readings will resume. The maximum damping value set by the FFD is
99 seconds.
