DILUTION SETTINGS – User-defined. This is only accessible when the vent flow is DILUTION.
PURGE FLOW – The set point for user required flow rate for purging the pressurized enclosure
DILUTION FLOW SP - The set-point for user required flow rate for dilution of the containment system
within the enclosure.
MIN FLOW SP – If flow goes below this set-point, the alarm is activated but enclosure contacts still
remain on. For de-energizing the enclosure contacts, set MIN OVERPRESSURE to the flow rate of
the vent selected for de-energizing.
Default values are as follows:
• PURGE FLOW = 0.0 l/min (0.0 scfm)
• DILUTION FLOW SP = 0.0 l/min (0.0 scfm)
• MIN FLOW SP = 0.0 l/min (0.0 scfm)
