Heating and cooling with constant period (
CyCl
=
3
)
1 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]
