The recirculation start warning time is the amount of time in seconds that the sounder
beacon operates before recirculation begins. This feature is provided as a safety
feature to warn operators the machine is about to start.
The recirculation stall time is used to set the maximum duration in seconds, which is
permitted to elapse before a recirculation stall fault is triggered. Therefore, if the
pumps stop during recirculation due to inadequate pressure being supplied to the air
cylinder, the user will know.
4.2. Flush
The flush configuration screen shown in Figure 4.2, allows the duration of flushes to
be set for both single flush and flush sequencer configurations.
The first button, flush warning time, is used to set the duration of the flush warning
count down timer in seconds. When adjusting this value, it should be remembered that
during this warning is the only opportunity for the user to cancel the flush.
Figure 4.2 – Flush configuration screen
The initial flush duration, sequenced flush time and final flush duration values are all
used by the flush sequencer when multiple autosprues are used. The initial flush
duration and final duration additionally have associated enable and disable buttons.
To change the duration of a flush, simply press the required button and enter the
desired time in seconds. It is recommended that a flush should last for at least 30
seconds; hence this is the minimum value which may be entered.
When multiple autosprues are connected to the system, if desired, the flush sequencer
can be used to control which autosprues are flushed. Table 4.0 illustrates the operation
of the flush sequencer when four autosprues are connected to the system (solvent
system recharge between flushes not illustrated). The initial flush and final flush,
where all of the autosprues are flushed together, can be separately disabled if required
by toggling the associated enable/disable buttons. The duration of the individual
flushes is determined by the sequenced flush time value.
