MODES OF OPERATION FOR COUNTER:
COUNT UP CONFIGURATION:
MODE 0: (Count up with manual reset to zero)
In this mode the system counts up from zero. Preset limits energize when the count reaches presets limit values. The unit
will continue counting up until manually reset. To reset the count manually, first select a channel by pushing CH SEL
key and ,while keeping CH SEL key pushed
, simultaneously push the RESET key . The display will read 'RESET'
and then the reset value of zero will be displayed. On resetting to zero, the outputs will automatically de-energize and
this will be indicated by the LED'S for the respective outputs turning off on the front panel.
MODE 1: (Count up to Preset with auto reset to zero)
In this mode the counter counts up to a preprogrammed preset value (look under SETUP). On reaching preset the counter
automatically resets to zero and starts the up count again. The count can be reset manually before it reaches preset. To
reset the count manually, first select a channel by pushing CH SEL key and ,while keeping the CH SEL key pushed
,
simultaneously push the RESET key. The display will read 'RESET' and then the reset value of zero will be displayed.
Preset limits energize when the count reaches limit values.
MODE 2: (Count up to Preset with auto Zero after delay)
In this mode the counter counts up from zero to a preset value. Preset limits energize when the count reaches limit
values. On reaching PRESET, the delay period starts. After the delay period is over, the count is automatically zeroed,
the limits, if energized (and in non-latch mode), are reset and the count up starts again. The delay period is programmed
in SET - UP mode.
For example, if PRESET is set to 9000 counts and the delay period is programmed for 10 seconds, then when the counter
reaches 9000, the delay period will start and after 10 seconds of reacing 9000 count, the count will be reset to zero.
COUNT DOWN CONFIGURATION
MODE 3: (Count down to zero with manual preset)
In this mode the counter counts down from a preset number (preset number is programmed during SETUP). On
reaching zero the counter will not decrement further until manually preset. To preset the counter value manually, push
CH SEL key to select a channel. While keeping CH SEL key pushed, go on to push the RESET key simultaneously.
The display will read 'RESET' and then the displayed value will be reset to zero. Count down will start immediately
thereafter.
When count goes down to a limit value the respective output is energized. The output will stay energized until the count
is preset as explained above.
MODE 4: (Count down to zero with auto preset)
In this mode the counter counts down from a pre-programmed preset value (look under SETUP). When count goes
down to limit value, the respective output gets energized. The display in the meantime will keep counting down. When
it reaches zero, it will automatically preset itself to the programmed preset value.
NOTE: i) Time delay in modes 2 and 5 must be less than the time required to count from zero to
preset or preset to zero.
MODE 5: (Count down to zero with auto preset after delay)
In this mode the counter counts down from a Preset value. Preset limits energize when the count reaches limit values. On
reaching zero, the delay period starts. After the delay period is over, the count is automatically preset, the limits, if
energized (and in non-latch mode), are reset and the count down starts again. The delay period is programmed in SET -
UP mode.
