FEC920: USER GUIDE
This is the rollover output which will be set for one execution cycle when the counter rolls
over. This output can be used to expand the range of the cascade counters by wiring it to
the Trigger input of the next counter.
This is the value at which the counter will rollover and is configurable in the same way as
the totalizer. When the counter rolls over the difference between the rollover value and the
calculated output will be added to 0.
Example 1: with a rollover value of 1000 and a current output of 999 and an input of 5,
then the output will become 4 when the counter is next triggered.
Example 2: with a rollover value of -1000 and a current output of -999 and an input of -5,
then the output will become -4 when the counter is next triggered.
Allows the user temporarily to suspend counting. The output retains the pre-disabled
value until the counter is re-enabled, when it resumes counting from that value. The
counter is toggled between being enabled (cross symbol) and disabled (tick symbol) by
means of the scroll key.
