Page 7: General Description
The High Voltage/Power Cabinet is produced to accommodate one, two or three sources. The number of Source Filament Control modules determines the number of sources that can be driven. There are two versions of the TT-10/15 control modules: Source 1 Control and source 2/3 Control. The Source 1 Control contains: High Voltage Control and digital indicators(There is only one HV control for the main Power supply.) -

Questions and answers
We are currently experiencing an issue with our evaporator, where the AC fault parameters indicate that the low limit is set at 190 volts, while faults have been occurring in the high 170s volts range. To address this, we are considering adjusting the low limit to around 170. Could you please provide guidance on the following: Would setting the low limit to 170 volts potentially damage the power supply or other components of the evaporator? What are the recommended operable limits for the evaporator to ensure safe and efficient operation? Are there any additional considerations we should be aware of when making this adjustment? Thank you for your assistance. I look forward to your prompt response.
