If the Thermotron 8200 Plus does not power up after confirming there is power, possible issues could include:

1. Power Supply Issue – Ensure that the voltage input is between 18 to 28 Vdc and provides at least 12 watts of power.
2. Connection Problem – Check the ST1 interface cable that supplies power to the 8200+ from the control module.
3. Battery Issue – The replaceable battery (BH1) might need to be replaced.
4. Faulty Hardware – If all connections and power supply are correct, the unit itself may have a hardware failure.

Checking these components should help identify the cause of the issue.

An air-cooled or water-cooled condenser then removes the heat from the refrigerant of the second compressor. chamber: A general name for a Thermotron environmental simulation testing system. The chamber includes the testing section, the machinery section, the console, and, on air-cooled chambers, condensers.
Page 112 The final temperature or other process variable the chamber is to reach during an interval. GPIB: General Purpose Interface Bus; a parallel interface bus built under the IEEE-488 standard. This generic manual is not intended to be used to operate your equipment. Thermotron Industries...
Page 113 A channel used by the 8200+ for monitoring processes within the chamber. If the high or low limit is exceeded for any channel, the 8200+ alarm outputs are activated. Thermotron Industries This generic manual is not intended to be used to operate your equipment.

This level of control becomes available only with properly tuned proportional band and integral time parameters. Thermotron Industries This generic manual is not intended to be used to operate your equipment.
Page 118 If the process variable undershoots the setpoint slightly until it finally reaches the setpoint (if it ever does), the integral time is too large. • If the process variable overshoots the setpoint, the integral time is too small. This generic manual is not intended to be used to operate your equipment. Thermotron Industries...
Page 119 Run a cool-down test to see the effect of the change from step 2. If necessary readjust the cool parameters. Continue to run alternating heat-up and cool-down tests, adjusting the heat and cool parameters as needed to achieve the desired level of control.

• As a rule for the integral time, shorter = faster response, longer = slower response. Generally, shorter integral times mean shorter transition times. Thermotron Industries This generic manual is not intended to be used to operate your equipment.
Page 122 NOTE: When tuning parameters, heating parameters are usually tuned before cooling parameters. Normally you should select the setpoint based on the tests you are running. Set the Ramp Rate to 0. This generic manual is not intended to be used to operate your equipment. Thermotron Industries...
