Temperature Sensor Voltage Sensor Relay Operation Example
The example below outlines the relay operation.
Looking at Box B “Relay Enabled” in the picture above:
When “Relay Enabled “is set to False, it means the Voltage Sensor readings of the IONPS-D-R1 in slot 22
[Box A] will
not
have any effect on the Dry Contact Relay alarm indications. No alarm will ever be set
based on power supply voltage output.
When “Relay Enabled is set to True, it means the Voltage Sensor readings of the IONPS-D-R1 in slot 22
[Box A] will affect the Dry Contact Relay alarm indications. Power supply voltage output that is too high
or too low will set an alarm.
When the Relay Enabled is set to “True”, the Threshold settings show the conditions that will indicate
alarm. Those conditions are editable. Any condition showing “True” in the Last Evaluation column means an
alarm was occurring when the webpage was loaded or last refreshed.
With v 1.2.5 firmware or above, the relay operates per the table below:
