Intended use
Vestfrost biomedical freezers are designed to provide reliable temperature stability and precision
and ensure an ideal cold temperature storage for sensitive items is achieved. The products are
designed for the following operating ranges:
WARNING: This unit is not a “rapid-freeze” device. Freezing large quantities of liquid,
or high-water content items, will temporarily increase the chamber temperature and will cause
the compressors to operate for a prolonged time period. Avoid opening the door for extended
time periods since chamber temperature air will escape rapidly. Also, keep the inner doors closed
as much as possible. When room air, which is higher in humidity, replaces chamber air, frost may
develop in the chamber more rapidly.

Your device is equipped with a remote alarm
connection to send alarm signals to a building
management system, a monitoring unit, visual
or acoustical warning device etc.
The alarm output is managed freely by the
built in controller of the unit.
Alarm criteria may be too low temperature,
too high temperature, power failure, open
door or similar.
The alarm output is an electrical floating
output (dry contact) which acts like a ON/OFF
switch.
A SPDT (single pole, dual throw) relay with
maximum switch rating of 250V 3A is main-
tained by the build-in XW737K controller unit.
The relay terminals are explained this way:
COM: COMMON terminal
NO: NORMALLY OPEN terminal.
Connects to COM when the alarm is activated
NC: NORMALLY CLOSED terminal.
Disconnects from COM when the alarm is
activated
An alarm interface cable of maximum
30 meters can be attached without the use of
tools to the 3-pole alarm clamp connector.
Wire thickness must be within 0.5mm² to
2.5mm² and fitted with core crimp terminals.
