Blue M - - DC 146 Series Industrial Ovens, Models DC, DCW, DCI, DCC

Oxygen Analyzer / Transmitter - Optional:
An oxygen analyzer or transmitter may be employed in the Model DCC and DCI ovens. Percent oxygen
instruments are used to measure oxygen as a percent of atmospheric volume within the chamber. Trace
oxygen instruments are used to measure trace oxygen in ppm of atmospheric volume within the chamber.
Analyzers are complete programmable type instruments with digital process displays. Transmitters transmit a
4-20 ma output signal to the main temperature controller to indicate oxygen levels. Both types will activate
alarm circuitry and cause the shutdown of the heating system to prevent either an oxidizing condition or a
potential explosive condition.
Door Limit Switch – Optional:
An oven door limit switch may be employed to enable the control circuitry only after the oven door is closed
securely. Opening the door during the process cycle will shut down the heating system and the circulation
blower motor.
Electro-mechanical or Pneumatic Door Lock – Optional:
Either an Electro-mechanical or a Pneumatic Door Lock may be provided to prevent the oven door from
being opened after the process cycle has begun. An Event Output from a profiling type controller is used to
lock the door with the start of the process.
Additional Options:
Blue M ovens are designed with the capability to incorporate many other optional features for safety
purposes, enhanced process control, and simplified operator interface. Consult a Blue M Applications
Engineer or our Service Department for more information or questions. And thanks for choosing a Blue M
Oven!
3.4 Operating Parameters and Requirements
This equipment is designed to operate safely when the following environmental conditions are met:
Indoor use only.
Within a temperature range of 5°C to 30°C (max).
Maximum relative humidity 90%.
The listed chamber specifications are based on operation at 24° C ambient temperature, altitude at sea level,
and a 60 Hz power supply. Chamber operation utilizing a 50 Hz power supply may derate the listed
performance specifications.
Equipment damage, personal injury, or death may result if this equipment is operated or maintained by
untrained personnel. Operators and service personnel must be familiar with the location and function of all
controls and the inherent dangers of the equipment before operating or maintaining it. TPS shall not be liable
for any damages, including incidental and/or consequential damages, regardless of the legal theory
asserted, including negligence and/or strict liability. Observe all safety warnings and operating parameters
listed in this manual, as well as all Caution, Danger, and Warning signs or labels mounted on the equipment
to reduce the risk of equipment damage and personal injury.
