USE AND MAINTENANCE MANUAL
With
SEq=0
the activation/deactivation of the digital outputs is a time-based operation, and
in particular:
- The output that has the least number of operating hours in times
t1C/U
,
t2C/U
,
t3C/U
and
t4C/U
, and that is available at that time (therefore not in alarm).
- The output that has the largest number of operating hours in times
t1C/U
,
t2C/U
,
t3C/U
,
t4C/U
is deactivated
.
Delays on the activations of the outputs
“
t1C/U
” determines the minimum time that must elapse between the insertion of a step and
the next one. This parameter avoids breakaways caused by simultaneous start-ups.
“
t2C/U
” determines the minimum time that must elapse between the deactivation of two
different steps.
“
t3C/U
” determines the minimum time that must elapse between two subsequent
insertions of the same step. This parameter allows you to limit the number of start-ups per
hour if the controlled motors require this.
“
t4C/U
” determines the minimum time that must elapse between one shutdown and the
next insertion of the same compressor step.
On the LCD display the icons bar relative to fans and compressors (see par 5.4 ) will flash
when its output is pending ON or OFF due to these times.
