4.3.6 Heating and cooling with constant period ( CyCl=3 )
The adjusted cycle times t1 and t2
are met in the overall output range . To
prevent unreasonably short pulses,
parameter tp is used for adjusting the
shortest pulse duration. With small
correcting values which require a pulse
shorter than the value adjusted in
tp,
this pulse is suppressed. However, the
controller stores the pulse and totalizes
further pulses, until a pulse of duration
tp can be output.
Parameters to be adjusted
t1 : Min. cycle time 1 (heating) [s]
( PArA/ Cntr) t2 : min. cycle time 2 (cooling) [s]
tp: min. pulse length [s]
