(1) Output control is maintained after count-up completion and until reset. However counting is
possible despite of count-up completion.
(2) It reverts ‘0’ after counting up full scale, but output control is maintained. However output is OFF
if count value or preset value is changed.
●
Change the Preset Value
It is possible to change the preset value even during counting. However note the following points.
◇
When the pre-scale value is ‘1.000’.
(
PSCL=1.000
)
(1) If the preset value is changed to the value less than the count value, counting will continue until
it reaches full scale, returns to ‘0’ and then reaches the new preset value.
(2) If the preset value is changed to ‘0’, it will not count up at start with ‘0’. It counts up when the
counting value comes to ‘0’ again (after reach to full scale). However output is OFF if count
value or preset value is changed.
(3) When the count value is fixed, output is changed according to the changing of preset value as
below.
①
If the preset value is changed to the value less than the count value or same as count value,
output is ON.
(
Count value
≧
Preset value
)
②
If the preset value is changed to the value more than the count value, output is OFF.
(
Count value
<
Preset value
)
◇
When the pre-scale is not ‘1.000’.
(
PSCL
≠
1.000
)
Even if the preset value is changed after counting to full scale, output is not changed.
