Decide what to do when in Alarm StateIf the logger is alarm state, the logger can energize Alarm1 and/or A2/E terminals in order tocontrol the external devices like siren auto dialer etc. It can also report the alarm to SiteView viaModem dial-out.At the left side of the above figure, you can change Alarm/Excitation Selection to decide whichterminals the logger will work with when there is an alarm. You can also change Notify Alarmvia Modem to decide if the logger will dial out the connected Modem to the remote Modemwhich is connected to the PC where SiteView is running.Please refer to Receive Alarm Notifications chapter for detailed instructions on how to make thelogger to report the alarm to SiteView.Configure Excitation ControlExcitation output is used when you need to save the electric power of the device that provides thesignal source to the data logger. When there is no local power available and a battery pack is usedto power the transducer, excitation control greatly reduces power consumption by turning on thetransducer only when it samples the data and turning off the transducer after the sampling.A2/E on the terminal strips can be configured by for excitation purpose.In order to enable A2/E, one of the following Alarm/Excitation Selection must be selected:Excitation control to A2/E, both high and low alarm to Alarm1Excitation control to A2/E, low alarm to Alarm1Excitation control to A2/E, high alarm to Alarm1Excitation Warm-up Delay is used to specify how much delay will be set after the excitationterminal is activated and before the logger is taking the sample. If the measurement source deviceneeds certain time to stabilize the signal output you may need to set this parameter so the loggerwill wait certain time before it takes the sample.SiteView User’s Manual – Microedge Instruments Inc. 49/200
