11.1 Recirculation Operation
The status of the Aquarius
®
system with Recirculation is indicated on the System Status
screen of the user interface. To access the Recirculation sub-menu, press the Recirculation
key (∞). The Recirculation key is located at the bottom left of the System Status screen. The
three different modes of the Recirculation System are illustrated by a series of labels and/or
illuminated green indicating lights. These three modes are:
1.
Demand
: This is the default mode of the system. The Recirculation System is not active
and the fluid is being sent to process.
2. Venting
: The Recirculation System is preparing to initiate and is filling the pump and
plumbing with fluid and/or evacuating any air/bubbles from the plumbing. This mode will
activate anytime excessive air/bubbles are detected within the recirculation plumbing.
3. Recirculation
: The Recirculation System is active and no fluid is being diverted to
process. An external signal is required in order to initiate this mode.
The Aquarius ®
system has been configured to default to the “ Demand
” mode.
To place the Aquarius ® into Recirculation mode several conditions must occur:
1. The Recirculation System must be enabled.
2. A customer provided “Recirculation Signal” is required to send the system into the
Recirculation mode.
3. The Venting mode cannot be active.
If the above conditions are not met, the system will fail to enter “ Recirculation ” mode and
remain in “
Demand
” mode. Please note that the presence of any “critical” alarms will abort
recirculation by shutting off the pump and deactivating the heaters. Once “critical” alarms are
resolved, recirculation will automatically resume but the system will be in “ Standby ” mode
and the heaters will remain OFF until the system is placed back into the “ Active ” mode.
Please follow all Pre-Installation Preparation, Installation, Suggested Operational Inspection
procedures and the Pump Air Cooling System Set Up and Calibration prior to activating
recirculation. This includes the connection of an external maintain switch/signal to the
Aquarius ® “Recirculation Signal”. The Recirculation Signal is available for Discrete and
Ethernet communication connections. Please refer to the specific Electrical Component
Layout drawing and the Electrical Schematic drawing for more information.
To initiate the Recirculation mode from Demand mode:
1. Recirculation System DISABLED / ENABLED key located on the System Status screen
enables/disables the Recirculation System. To enable the system press the DISABLED
key. The “Disabled” label will change to “Enabled” and will be illuminated yellow.
2. Provide a closed “Recirculation Signal” to the system to initiate the “Recirculation” mode.
To return back to the Demand mode from the Recirculation mode:
1. Provide an open “Recirculation Signal” to the system to initiate the “Demand” mode.
Note
: If Recirculation System is disabled, “Recirculation Signal” has no affect on recirculation.
