Note!
The following parameters must be entered for the purge time:
Enclosure volume
Number of exchanges
Type of vent for flow rate—enter flow rate
Minimum purge time is 2 min.
Fixed Purge Time
The purge time is based on the known enclosure volume, number of volume exchanges, and flow rate
through the vent. If the flow rate is below the required minimum, then the purging cycle will reset and will not
start until the flow rate is above the selected rate. This setup does not allow purge flow to go below the value
required and will not recalculate the time for purging if it goes above the required purge rate. The actual time is
calculated by the EPCU.
Purging modes
Purging start-up can be set in 3 different modes:
STD – Standard mode requires the operator to engage the manifold solenoid valve manually when
purging and manually disengage when a successful purging is complete.
SA – Semi-automatic mode requires the operator to engage the manifold solenoid valve manually when
purging. The EPCU will automatically disengage when a successful purging is complete.
FA – Fully-automatic mode will automatically engage the manifold solenoid valve when safe pressure
is detected and will automatically disengage when a successful purging is complete. This is the factory
default setting.
The minimum purge time is 2 minutes.
During the purging cycle, when the enclosure pressure reaches 0.25" wc [(6.4 mm wc) or higher, there will
be a 5 second delay before the rapid exchange solenoid valve is activated. If the flow is enough through the
vent to satisfy the required flow rate setting, then the timer will begin after 1 min. The update of the timer is in
increments of 1min in the Fixed Purge Time and % completed in the Dynamic Purge Time.
Pressure as Input
In the programming menu under "INPUT SETTINGS" for the optional pressure control. The pressure control
is achieved within the enclosure by opening and closing a purging valve or manifold on the 6100 control unit.
These two internal pressure set points are controlled by the manifold or an outside source for pressure. The
pressure function can manage the control output 2, or the control valve (manifold valve).
