Page 7: Safety Information
Chart Environmental Chambers Your Chart equipment is provided with several safety systems designed to help prevent accidental damage to product and equipment, and avoid injury to personnel. Always operate this equipment in accordance with the procedures set forth in the OPERATION section of this manual. The safety systems described below should be checked at least once every 30 days, and any inoperative or questionable conditions must be corrected before resuming operation. -
Page 8: Description Of Safety Features
Chart Environmental Chambers Description of Safety Features On each unit, there are a number of features, which help to ensure safe operation. These features are: Temperature High/Low Limit Control: A user-programmable limit control is provided as an independent measure of safety against thermal runaway (hot or cold), which could occur from, but not limited to, the following: Programming error... -

S y s t e m Cooling Heating 2 kW (4 kW in HP model) of heat provided by open nichrome wire heating elements. Time proportional solid state control of resistive heating elements in air conditioning plenum. Programmable Control and Data Logging Controller Watlow Series 96 temperature controller. -
Page 10: Features
Chart Environmental Chambers Temperature Control System: Heating is accomplished with resistive electric elements, while cooling is accomplished by blowing liquid nitrogen into the chamber. The liquid nitrogen is vaporized through nozzles and the cold vapor is circulated over the products in the chamber so that liquid nitrogen does not touch the product under test. -

Chart Environmental Chambers the air-flow plenum and is not directly visible. The following figure is a picture of the Watlow controller: Temperature Safety Controller A temperature Hi/Lo limit control protects the chamber against thermal runaway due to a primary controller fault or control device failure. The input to the Hi/Lo limit control is a type T thermocouple. -
Page 12: System Installation
Chart Environmental Chambers Location The location of the chamber should be chosen with a few items in mind: The left side of the chamber has an access port, which allows passing power and data acquisition wires into the chamber and connecting to the device under test. The top side of the chamber has the control box. -

Chart Environmental Chambers suction into the blower in the back wall of the chamber and discharge from the top of the chamber. Liquid Nitrogen Plumbing Along with the electrical power, bring in the LN chamber for easy access around the chamber. The connection point is at the solenoid valve on the back wall of the chamber. - Page 14 Chart Environmental Chambers System Installation It may be possible to run the chamber without the exhaust gas plumbed out of the building. An evaluation of the size of the room containing the chamber, as well as the ventilation system (number of air changes) must be done to determine this. If it is determined that the room is ventilated well enough to not plumb the exhaust gas out of the building, it is highly recommended to install an oxygen monitor in the vicinity of the chamber to ensure safe working conditions for all personnel.

Page 15: Operation
Chart Environmental Chambers Check system functions and your understanding of the system by following these steps with an empty thermal enclosure before installing the product to be tested. 1. Verify that all utilities are on-line before operating equipment. Liquid nitrogen is required for proper cooling. - Page 16 Chart Environmental Chambers 2. Control Power (OFF, ON) This switch controls the 24vdc control power in the control system. If this switch is turned OFF, all control functions will be disabled. The temperature controllers are powered from a 115vac circuit, so they will remain powered up even if the control power switch is turned OFF, however no heating, cooling, etc will be able to take place.

Chart Environmental Chambers Watlow Series 96 Controller Operation NOTE: For more complete instructions on the operation of the Watlow Series 96 controller, refer to the supplied manual. All information in the Watlow controller manual takes precedence over information shown in this manual. Entering Temperature Set Points The temperature set point for the chamber is displayed on the bottom display of the Watlow controller. -
Page 18: Air Safety Controller Operation
Chart Environmental Chambers Heating/Cooling Indicators When the Watlow controller is applying a heat or cool signal, an LED is indicated on the front panel. The longer the particular LED is on, the more heating/cooling power is being applied. If the LED is continuously on, that indicates full heating/cooling power. If a heating signal is being applied, the LED by the number 1 will be illuminated, if a cooling signal is being applied, the LED by the number 2 will be illuminated. -
Page 19: System Maintenance
Chart Environmental Chambers Maintenance of this equipment should be done by a qualified technician. High voltage electrical systems, cryogenic plumbing, and mechanical systems all represent a potential for injury or death. The main power must be removed from the chamber, and the liquid nitrogen supply should be disconnected prior to servicing this equipment. -
