NOTE

Operator safety

The CT-500 comes equipped with a number of safety features:
A second thermistor in the temperature bath senses any over-temperature
fault condition. If such a condition occurs, all power is removed from the
bath until an operator corrects the problem and resets the over-tempera-
ture limit circuit.
If the control thermistor is disconnected, all power to the bath heaters is
cut off.
The CT-500 will not operate if the liquid level in the bath is too low. If
such a condition occurs, all power is removed from the bath until the
liquid level in the bath is restored to the minimum safe level.
Safety devices may be impaired if equipment is not operated per manual
instructions.
All technicians who use the CT-500 should follow these basic safety
procedures:
• The CT-500 power cord should only be connected to a suitable AC
mains power source (with protective earth ground) matching the
specifications of the S/N label on the CT-500 rear panel.
• The CT-500 should be placed on a stable laboratory table or bench.
• If any liquids are spilled in or around any electronic components of
the CT-500, remove power and contact CANNON
Company before introducing power to the system again.
• Position power cords so that they are not likely to be walked on or
pinched by items placed on or against them. Keep all connections as
neat as possible.
• To disconnect the power cord, pull it out by the plug. Never pull the
cord itself.
• Do not attempt to service the CT-500 system by removing panels and
trying to effect repairs. Contact CANNON
all service and repair needs.
• Monitor bath fluid level carefully and use caution when operating at
temperature set points above ambient temperature. Liquid may
expand and overflow the jar.
• Observe appropriate safety precautions when handling bath fluid
(refer to the Material Safety Data Sheet included with the bath fluid
for more details.)
CAUTION
Never use flammable bath liquids in any CT-500 bath.
