Manual or Automatic Total Reset Function (t rST)
For manual reset, select T RESET  t rst  man and then select whether manual
reset will be enabled (Enabl) or disabled (dsabl) using the Up arrow key. Press the
Enter
button to accept. Disabling reset will avoid inadvertent resets of the total via
the front reset button or external reset contact.
For automatic reset, select T RESET  t rst  Auto T DELAY and enter reset
delay time in seconds. Once the output alarm total set point is reached, the meter
waits for a programmed amount of time (T DELAY) and then resets the total to zero.
For timed reset, select T RESET  t rst  Time T RESET and enter the time of
day at which the total should be reset. The total value will be reset every day at the
specified time.
Press the Enter button, at any time, to accept a setting; otherwise press the Menu
button to exit without saving changes.
Total Alarm Time
The T DELAY parameter is used by the NPN open collector outputs when they are
programmed as total alarms. If total reset (t rst) is programmed to Auto the time
delay (T DELAY
) is the length of the associated Out 1 or Out 2 total alarm prior to the
total being reset to 0.
For information on programming the NPN open collector pulse outputs as total
alarms, see Alarm Output programming on page 62.
