Mc/Mcr - Delta C2000 series User Manual

When the CNT command is executed from OFFON, which means that the counter
coil is driven, and 1 should thus be added to the counter's value; when the counter
achieved specific set value (value of counter = the setting value), motion of the
contact is as follows:
NO(Normally Open) contact
NC(Normally Close) contact
If there is counting pulse input after counting is attained, the contacts and the counting
values will be unchanged. To re-count or to conduct the CLEAR motion, please use
the RST command.
