Analogue alarm settings
When configuring an analogue input you need to set Alarm High "Set Point", Alarm Low
"Reset Point", and select the "Analogue trig type".
The "Analogue trig type" setting will decide how the analogue signal is tested against the
"Set Point" and "Reset Point". Sensor signals out of normal operating range will
generate an Input alarm trigger to the Group.
High SP
Low SP
Shows the relationship between Set Point and Reset Point, and the analogue
signal.
(High SP = Set Point, Low SP = Reset Point).
The following trigger types are supported:
Trigger when high
- Trigger when the analogue signal is above the "Set point".
- Remove the trigger when the analogue signal is below the "Reset point".
Trigger when low
- Trigger when the analogue signal is below the "Set point".
- Remove the trigger when the analogue signal is above the "Reset point".
Note: The "Set point" value must be smaller than the "Reset point".
Outside set/reset point
- Trigger when the analogue signal is above the "Set point" or below the "Reset point".
- Remove the trigger when the analogue signal is between the "Set point" and the "Reset
point".
Between set/reset points
- Trigger when the analogue signal is between the "Set point" and the "Reset point".
- Remove the trigger when the analogue signal is above the "Set point" or below the
"Reset point".
