Output Mode
Click on the radio buttons to manually control the alarm relay. The normal selection will be Auto ,
where the WebAlert uses the various set points to open and close the relay. You can force the relay
open regardless of the presence of an alarm condition by selecting
Off , or force the relay closed
regardless of the presence of an alarm condition by selecting Hand .
If you select Off, the alarm relay will not be triggered again until either Hand or Auto is selected, or
unless power to the unit is cycled off and on! If you select Hand, the relay will be closed until either
Auto or Off is selected, or until the Hand Time Limit (programmed in the next menu) expires.
The Off mode is handy to use as an alarm silence. The Hand mode is handy to be able to test the relay,
wiring, etc without needing to force an alarm condition.
Hand Time Limit
Type in the text box the maximum number of minutes that the alarm output can be activated in the
Hand mode. Any value between 0 and 1440 is acceptable. A value of 0 means the output can be left on
indefinitely.
