Configuring the signal output (FSH and FSL)
Fail Safe High (FSH) and Fail Safe Low (FSL) configurations are supported on
the following electronic modules:
•
SPDT relay
•
DPDT relay
•
3-wire PNP
•
2-wire without contact
shows the SPDT relay electronics module as an example. The
other modules have the same configuration switch and default setting.
FSH signal output
When the level switch is used to indicate full-silo, set to
Fail Safe High
. A
power failure or line break is regarded as full-silo signal (as protection
against overfilling).
FSL signal output
When the level switch is used to indicate empty load, set to
Fail Safe Low
. A
power failure or line break is regarded as empty-silo signal (as protection
against running dry).
