Digital Input? - Input True State - Input False State Input trigger % - Alarm Delay - Alarm Indicator - If ticked the input will operate as a digital input. If the input is digital, the user may enter the text to be displayed when the input is closed (true), for each input. If the input is digital, the user may enter the text to be displayed when the input is open (false), for each input. If the input is digital, the user may set a trigger %, at which the input reading must be above in order for a true state to be given. min 10% max 90% The alarm holdoff delay to be used. If set to 0 the alarm will be disabled. The colour of the alarm indicator on the overview page when the alarm is active. Alarm Indicator Activation - If true the input must be true in order to change the alarm indicator colour from green to red orange. If false the input must be false to change the indicator colour from green to red / orange. 3.4 Help page The help pages show basic information relating to the variables which can be changed within the setup pages

14 4. Unit Operation The unit constantly monitors its inputs; the raw reading of the input is converted according to the channel setup. The converted reading is then used to generate alarm depending on its value and the channel setup. Converted readings and logged in the datalog, alarms and other events are stored in the eventlog. 4.1 Input conversion Input readings are converted according to the channel settings Analogue inputs When set for an analogue input, The Input Min and Input Max setup the range of the sensor connected to input, i.e.; Input Min = 0% Input Max = 50% Start of Range = 0VDC End of Range = 5VDC The Scale Min and Scale Max setup the actual measured range of the sensor, ie, Scale Min = 0 Scale Max = at start of range 100 at end of range The Units defines the character to be displayed after the converted value Analogue input setup examples For a 0-5VDC Liquid level sensor, Input Min = 0% Scale Min = 0 Input Max = 50% Scale Max = 99 Units = % For a 4-20mA Liquid level sensor, Input Min = 10% Scale Min = 0 Input Max = 50% Scale Max = 99 Unit = % Digital inputs When set for a digital input, the Input Trigger % sets the voltage at which the input changes state, i.e., Input Trigger % = 20% Input 2VDC The Input True State and Input False State specify the state to be displayed when the input is true, ie if the Input Trigger % = 20%; Input True State = CLOSED Input False State = OPEN CLOSED if input higher than 2VDC OPEN if input lower than 2VDC When changing between states the De-bounce period is applied, i.e. if the De-bounce period is set to 12 seconds, the input must remain in the new state for 12 seconds before the displayed value changes state

15 4.2 Event log The event log is used to store events such as alarms, setting alterations and power resets. The unit will record a maximum 100 events on first in, first out basis. The event log can only be viewed using the XML reports. For when an event occurs the unit records the following, The input number The digital input name OR analogue input alarm text OR Power up /Config. change The current date (DD/MM/YYYY) The current time (HH:MM:SS) The current status of the input (the actual status of the input if digital, ALARM or Healthy if analogue) The contents of the event log will be cleared if the user performs a factory reset. 4.3 Data log The data log will record the status of all inputs at the setup logging rate. The unit will record a maximum 100 samples on first in, first out basis. The data log can only be viewed using the XML reports. Each datalog entry will record, The sample date (DD/MM/YYYY) The sample time (HH:MM:SS) The input number The input name The current reading of every input The contents of the data log will be cleared if the user performs a factory reset. 4.4 Alarms The unit records input alarm events (for inputs configured as digital or analogue inputs) Analogue input alarms If the input is configured as an analogue input, for each input there will be two separate alarm set points, hysteresis set points and alarm hold off delays generating two possible alarm events for each input. It is also be possible to change the sense of the alarm i.e. if the reading must be above (high) the alarm set point or below (low) the alarm set point for an alarm to be generated. Alarms are generated in the following manner, When the sense is set to low, An alarm will occur if, 1. The analogue input falls below the alarm set point 2. And remains below the alarm set point for the duration of the alarm delay An alarm will clear if, 1. The analogue input rises above the alarm set point + hysteresis set point

16 When the sense is set to high, An alarm will occur if, 1. The analogue input rises above the alarm set point 2. And remains above the alarm set point for the duration of the alarm delay Digital input alarms An alarm will clear if, 1. The analogue input falls below the alarm set point - hysteresis set point For inputs configured to operate as digital inputs, an event is recorded whenever an input changes state (if enabled to do so). An alarm will occur if, 1. The input enters the alarm condition 2. And remains in this condition, continuously for the duration of an alarm delay timer. An alarm will clear if, 1. The returns to the normal condition At power up, if an input reading meets criteria 1. for an alarm, criteria 2. must be applied from the point the unit is powered up. If a unit is reconfigured, in anyway, alarms will be reset as per a power up

17 5. XML Reports The XML reports enable third party alarm servers and management systems to read status information from the unit. 5.1 XML Status report The XML Status report displays the same information as displayed on the main Overview web page.
