3.8 Automatic Voltage Compensation System
The Forma Ultra-Low Temperature Freezer is equipped with an automatic line
voltage compensation system which monitors in-coming electrical power and automatically
adjusts the voltage directed to the freezer power supply. This compensation system ensures
that the compressor operates within specification and provides an additional margin of
product protection.
A green LED indicating light, labeled
"Voltage Compensation", indicates when the
system is in operation. The light is located on the
front of the compressor section. (See Figure 3-2)
3.9 CoBex Temperature Recorder (optional)
Operation of the recorder chart drive is
automatic when power is applied to the freezer. In
the event of a power failure, the 9 Volt back-up
battery will allow the recorder to sense and record
temperature for about 24 hours. Refer to Section
4.4 and the CoBex booklet included with this
manual.
