39. e relay contacts are open when conditions are normal and closed when CO is detected The natural tendency of most people is to assume that 0 means off and 100 means on and so they would naturally expect to see a 0 on the WatchDog 100 s display when the CO detector s alarm is off and 100 when the alarm is on but with the default analog input scaling it would actually display the other way around 100 would mean the alarm was off while O would mean the alarm was on On the other hand the default scaling would work perfectly well for a device with a normally closed relay contact pair where the contacts are closed when conditions are normal and open when an alarm state occurs as the closed contacts would keep the displayed value at 0 until the sensor is tripped By changing the analog input channel s range scaling this behavior can be reversed so that the CO detector s state will be shown in the manner the user would normally expect Instead of the defaults of Min 0 and Max 100 simply reverse them so that Min 100 and Max 0 instead Anats Input Reading defuiliO 100 cake This brings up an important point despite the names of these two opgn parameters Min does not necessarily have to be smaller than Max switcx These settings simply define the endpoints of a line running from the Minimum input voltage of OV to the Maximum input voltage of 5V When the input signal vol
