Omega Speaker Systems DPS3301 manual Timer Modes, Elapsed Time

Page 18

To display Timer #1 value, push the TIME key twice. The first push shows elapsed time, while the second push will first display 'tr1 Cnt' (for Timer1 Count) and then Timer 1 value.

To display Timer #2 value, push TIMER key three times. First two pushes display elapsed time and timer 1 value respectively, while the third push brings up timer 2 value on the display. This is , however, preceded by the message 'tr2 Cnt' (for Timer 2 Count).

Resetting Timers:

The two Timers can be reset any time and their timing cycle started all over again. To reset Timer 1, push ‘TIMER’ key twice and hold it in. This will bring time left on Timer 1 on the display. While this is being displayed, simultaneously push the ‘RESET’ key. Timer 1 will reset and its timing cycle will start again (depending on Timer Mode and Process reading i.e. if it is above Limit 1or below).

Similarly, to reset Timer 2, push ‘TIMER’ key three times and hold it in. This will display remaining time onTimer2. While this is being displayed, simultaneously push the ‘RESET’ key. Timer 2 will reset and its timing cycle will start again (depending on Timer Mode and Process reading i.e. if it is above Limit 2 or below).

TIMER MODES

Timer Mode #0

The timer starts timing from the moment the system is either turned on or the timer is reset. After the programmed amount of time has elapsed, the respective timer outputs will energize.

Timer Mode #1

When temperature Limit #1 or Limit #2 has been reached, the corresponding timer output (Timer #1 output for temperature Limit #1 and Timer #2 for temperature Limit #2) will energize and will stay energized for programmed length of time. After this time has elapsed, the output will de-energize.

Timer Mode #2

The timing for respective timers starts after the temperature Limit #1 or Limit #2 has been reached. For example, if temperature Limit #1 and Limit #2 are 500 and 1000 degrees respectively and Timer 1 and Timer 2 are programmed for 30 minutes each, then Timer 1 output will come on 30 minutes after the system reads 500 degrees temperature. Similarly Timer 2 output will come on 30 minutes after 1000 degrees temperature has been reached.

ELAPSED TIME

The system keeps track of process run time since the unit is turned on or the time is last reset. To display elapsed time, press the ‘TIME’ key. The display will briefly read 'ELPSd t' (for elapsed time), and then indicate process run time. Display format is HH.MM.SS (HH=hours, MM = minutes, SS = Seconds).

Maximum time that can be displayed is 999 hours 59 minutes and 59seconds.

How to reset Elapsed Time

To reset elapsed time and start timing again, press ‘TIMER’ key once and while keeping it pressed, push ‘RESET’ key. The display will show current elapsed time very briefly, and then reset to 0.
