Concoa CryoWiz User Manual

Switchover
Depletion of the primary LN2 supply is detected when low dewar pressure is observed or when a purge to
reach the threshold temperature has timed out. The CryoWiz™ automatically switches to the reserve bank
and maintains an uninterrupted LN2 supply. The CryoWiz™ will alarm audibly, indicate “ALARM” with a red
light on the front graphic, indicate “REPLACE” with a red light for the depleted side on the front graphic,
send an electronic signal to a remote alarm if one is connected, and switch to the reserve supply side.
Oxygen Deficiency Monitor Input
It is recommended that an output from an oxygen deficiency monitor be permanently connected to the
CryoWiz™ for a safe and correct installation. The CryoWiz™ comes with a terminal strip under a cover on
the left side of the enclosure to which the output contact from an oxygen deficiency monitor can be
connected. When the oxygen deficiency monitor relay contact is broken, the red “O2” “ALERTS” light on the
front graphic will illuminate, and the system will shut down until the alarm condition has been cleared (see
section “Connecting an Oxygen Deficiency Monitor”).
Manual Bank Switching
It is possible to manually change the side from which LN2 is being drawn: press the “SOURCE” button on the
front graphic. Switching will occur only if there is a sufficient LN2 supply on the reserve side.
Purging
The CryoWiz™ will automatically purge hot gas as needed to reach the desired temperature threshold for liquid
delivery. Manual purging is possible by pushing and holding the “LEFT PURGE” or “RIGHT PURGE” button on
the front graphic. The system will purge as long as the button is held.
Units of Measure
The units of measure for the CryoWiz™ are Celsius and PSI. They are not changeable. The displays of the
units are available thru the Web Server.
Security Lockout
The CryoWiz™ has the ability to electronically lock-out the front panel buttons to discourage tampering.
The factory default setting is OFF or disabled for this feature (see “Keypad Lockout” section for details).
Alarm Notification
The CryoWiz™ has a local audible and visual alarm for 5 conditions: 1) left bank depleted; 2) right bank
depleted; 3) pneumatic supply pressure low; 4) cryogenic valve frozen; 5) oxygen deficiency relayed from a
separate oxygen deficiency monitor. The CryoWiz™ is designed to interface with CONCOA remote alarms
(e.g., CONCOA Altos 2 Alarm 5750025-01-000 or CONCOA Advantium 16 Alarm 5750164-01-000). The
normally closed dry contact output from the CryoWiz™ can be configured as five individual alarms or a single
alarm contact. Refer to the alarm instruction manual for wiring instructions (CONCOA instruction manual
99060025 [ADI0025] for the Altos 2 alarm, instruction manual 99069531 [ADI9531] for the Advantium 16
alarm). Note that because the Altos 2 alarm supports a maximum of 2 inputs, it would normally be configured
to detect the left and right bank alarms only or the master alarm. The Advantium 16 supports a maximum of
16 inputs, and can handle all 5 CryoWiz™ alarms independently.
Ethernet Port / Web Server
The CryoWiz™ is equipped with an integral Web Server enabling remote monitoring of functions,
E-mail alerts, and remote configuration. For more information on the Web Server feature, refer to the web
server instruction manual included with the CryoWiz™ (CONCOA manual 99065774 [ADI5774]).
USB Port
The USB port should only be used by factory trained and authorized CONCOA Service Center technicians
during factory warranty installations and system configuration.
Relief Valve Overpressure Protection
The CryoWiz™ is equipped with three 50 PSI cryogenic relief valves. The relief valves will protect the system
from pressure increases that may occur from the vaporization of trapped cryogenic liquid during operation.
