CYCL
Cycle Time
The time for the output to
complete ON to OFF to
ON cycle. Used only with
proportional control. A fast
cycle time provides better
control, but can cause
premature wear to contactor or
other power switching devices.
Magnetic contactors should not
be switched at less than a 30
second cycle time. This menu
is active when the dip switch is
set to “PI”.
