Locate the Remote Alarm Connector on the controller (#12 on page 7; #2 on page 8). This
is where the remote alarm or auto dialer will plug into the control unit. All Global Alarm
connections are dry contact relays with a max output of 24VDC@2A.
The Remote Alarm Connector is a Dry
Contact.
The Diagram shows connections for
wiring arrangement.
First, wires from the remote alarm or auto dialer must be connected to the plug-end which plugs into
the Remote Alarm Connector. Use the diagram to connect wires from the remote unit.
When unit goes into an alarm condition or loses power, the contacts will switch their “Open” or “Closed”
state to be the opposite of when there was not an alarm condition, thereby sending a signal to the
remote alarm or auto dialer. Wiring it to common and normally open will trigger the remote contact if a
power failure occurs
Cooling medium: Liquid nitrogen only (supplied by a pressurized cryogenic transport vessel)
Operating Pressure: 22 p.s.i.
This Unit has been tested and complies with the EN60601-1 Standards.
Power Supply Voltage: 120 Volts AC 60 Hz standard - 220 Volts AC 60/50 Hz optional
Amperage: 2 amp max
Fuse: VAC 2 amp Buss fuse; 220 volts slow-blow. (T2A 250V) (automotive glass tube type fuse)
Operating levels for LN
2
: Extra High Series: 1 to 31 inches (higher ll heights may be used, call CBS for more info)
V Series Models: 1 to 23 inches
IMPORTANT: Normal operating pressure is 25 p.s.i. max/ 20 p.s.i. min (22 p.s.i. recommended) if
the pressure is greater or less than, the eciency of your liquid nitrogen storage unit could be
aected. This could be noticeable in ways such as increased liquid use, level and source alarms.
