Timer Operating Mode
The charts on the following pages, show operating
modes for the Single Preset and Dual Preset Timer Models.
In the descriptions below, the “Main Preset” or “Output”
refers to “Preset 1” or “Output 1” on the Single Preset
Model. On the Dual Preset Model it refers to “Preset 2” or
“Output 2”.
Reset Type:
Auto - Unit automatically resets as programmed, when timer triggers main
preset’s output or at it’s timed output end.
Manual - Unit does not reset when timer triggers main preset’s output or at
it’s timed output end. The timer value can be manually reset by a User
Input or by Serial Communications command.
Reset to:
Zero - When reset (manually or automatically) timer value goes to zero. The
Main Preset Output is triggered when timer value reaches main Preset
Value.
Preset - When reset (manually or automatically), the main Preset value is
loaded into the timer value. The main Preset Output is triggered when
timer value reaches zero.
At Timed Output End:
When this mode is selected, Auto Reset occurs when the main preset’s
Output time elapses and the main output deactivates. If not selected, Auto
reset occurs when the main output is triggered.
Continue Timing at Main Output:
The timer continues timing when main output is triggered. To stop timing,
the “Run/Stop” terminal is put into the “Stop” state. This mode is useful for
repetitive, auto-cycling applications.
Stop Timing at Main Output:
The timer will stop when the main preset’s output is triggered. To resume
timing, a manual reset (User Input - rSt-E) is performed, which resets the
output and the stop condition. The Run/Stop input can also be used to restart
the timer by putting it in the “Stop” state and then back to the “Run” state.
Cycling the Run/Stop however, will not reset or affect any outputs. This
mode is used to provide “one-shot” capability.
