27. Note in firmware versions prior to v1 4 3 if you had more than one external sensor of the same type attached and had not changed their friendly names from the default values the data graph display tended to group them all together instead of differentiating between them due to the way sensor names and values were passed to the Javascript driven graph generator on the web page This can be resolved either by giving the sensors individually descriptive friendly names or preferably by upgrading the unit to firmware version v1 4 3 or higher Note that if the unit does not have enough data in memory to display the requested time range in full it will adjust the time range to the nearest time range which it can display in full For example ifa I day time range is requested when there are only 3 hours worth of data in the log the unit will change to the 8 hour range instead When this happens the unit will display a message indicating that the time range has been adjusted to one that better suits the amount of data available P Note in firmware versions prior to v1 4 3 it was necessary to have at least 15 minutes worth of data logged in memory before a graph could be generated Ifa graph is requested when the log is empty or has less than 15 minutes of data available the unit would display the message Insufficient data to produce chart This limitation was removed in v1 4 3 WatchDog 100 User Manual 32 rev 1403074

User Manual 45 rev 1403074 In this kind of application however important to note that when you set an alarm threshold to trip above or below a eran point the WatehDog 100 looks at tese numbers in strictly mathematical terms I you wanted to set an alarm to trip once the battery voltage has fallen to 36VDC or less as represented by the red shaded area in the graph above you would actually need to set the threshold to trip above 36 0 since mathematically speaking 35 is greater than 36 This may seem counter intuitive at first but it makes sense once you realize that the WatchDog 100 doesn t actually know what these readings represent all it knows is where the mathematically calculated values fall on the line between Min and Max Calculating Appropriate Max Scaling for Proportional Voltage Sensors When setting scaling values for proportional voltage sensors it is important to keep in mind that they are subject to the same scaling issues as those discussed for conductivity type sensors it is assumed by the WatchDog 100 that the sensor s maximum reading is always represented by a 5V signal at the analog input However not all sensors fall into this category some may have a maximum output voltage of less than 5V As an example consider a pressure sensor which is monitoring the levels of refrigerant in an air conditioning system According to the sensor s specifications the sensor s output is 4

V at its maximum pressure rating of I20PSI _ If you were to set Max to 120 the reported measurements would be inaccurate because unit would be trying to calculate the scaled readings based on an incorrect assumption that 5V input voltage represents 120PSI This effect can be compensated for by calculating a Max value which stretches the scali 5 Max X desired maximum measurement Sensors max voltage output ig as follows So if our pressure sensor s resistance is 4V 120PSI then the formula becomes Max 2 X120 4 Solving the above formula setting Max to 150 will stretch the scale so that when the sensor is at its maximum output voltage of 4V the calculated value for that voltage at the analog input terminal will work out to the sensor s true maximum measurement of 120PSL WatchDog 100 User Manual 46 rev 140307A Using the dry contact control relay The WatchDog 100 is equipped with a single dry contact control relay which can either be energized manually by the user or automatically in response to an alarm condition In addition the relay can be configured to either release de energize automatically when the alarm condition s associated with it have cleared or it can be made to stay energized until the user manually resets it Triggering the relay when alarm threshold s are exceeded The WatchDog 100 s control relay is one of the alarm actions which can be chosen from t
