Function Based Timers

The function based timers will allow the user to monitor whether a specific input goes above a certain setpoint and for how long the input is over the setpoint.  Select the timer to work with from the drop-down list.  The options are: Timer 1 – Timer 5. 

The function will determine what input to base the timer off of.  To select the function, click on the “Function” line and then click on the Edit button.  This will bring up a list of functions to use.  The choices are: DISABLED (No timer function), or Input 1 > Setpoint – Input 40 > Setpoint.  Select the desired option and click on the OK button to set the function, or click on the Cancel button to cancel
the action.  Note: Selecting a different function will reset the timer to zero.  To set the setpoint, click on the “Setpoint” line and then click on the Edit button.  This will bring up the numeric keypad so the user can enter the desired setpoint.  Note: Setting a different setpoint will reset the timer to zero.  Once a function and setpoint have been entered, the timer will begin to count if the function’s condition exists.  The value of the function is listed on the “Value” line, which shows the timer in terms of days, hours, and minutes.  The “Last Reset” line will display the most recent date the timer was reset to zero.  The “RESET” line will allow the user to force a reset for the timer.  The user will have to confirm the reset first.  To reset a timer, click on the “RESET” line and then click on the Edit button.  A message box will pop up confirming the reset.  Click on the Yes button to confirm and reset the timer, or click on the No or Cancel button to cancel the action.  Note:  Function based timers can be added as an input on a template, but they will not be displayed on the graph.
