English
High Level Alarm Switch
Application: an alarm output, high and/or high-high alarm, when the process material rises to a
high level.
Application Notes: It is common to apply the switch on vessels where the material is normally
below the unit's range. Under such a condition the Pointek ULS200 loses echo, and if
prolonged, defaults to fail-safe operation. As this would be a normal occurrence, it is not
advisable to select the fail-safe high option. If the high level switch is being applied to a vessel
within the 3 or 5 m range, a loss of echo and ensuing fail-safe condition would not be a
common occurrence and the fail-safe default could be used if requred.
High / Low Level Alarm Switch
Application: high and low level alarms.
Application Notes: If the material can fall below the unit's range, the Pointek ULS200 loses the
echo, and if prolonged, defaults to fail-safe operation. The fail-safe default should be set to suit
the application.
