Field Logger Input Signals
6.2 Alarm
The Field Logger has two relays (ALM1 and ALM2) which can be used as alarm outputs. They
can also be used as digital outputs. In this case, a Modbus command controls its logical state. When it
is used as alarms these relays can be associated to any input channel in an independent way. Two
distinct alarm Set-points can be set to every input channel performing a HIGH (Maximum) or LOW
(Minimum) functions.
The HIGH alarm will signal when the input exceeds the value configured in the respective Set-
point. The alarm LOW will be ON whenever the input signal is below its respective Set-point.
The alarms can be associated to any of the relays (or both). All input channels can share the same
relay; the output which will perform an “OR” logic with all the requests. In the case where various
channels use their alarms associated to the same output, the relay will be energized when any of the
channels enters into an alarm condition, remaining so as long as at least one alarm is using it.
