Page 6: Introduction / General Information
N /air, etc. The InstruTech® CCM502 Hornet™ module provides the basic signal conditioning required to turn a cold cathode vacuum gauge into a complete measuring instrument. The module provides a log-linear analog output for the measured pressure and requires a digital input to activate the sensor. -

Page 9: Important Safety Information
CCM502 Hornet 2 Important Safety Information InstruTech has designed and tested this product to provide safe and reliable service, provided it is installed and operated within the strict safety guidelines provided in this manual. Please read and follow all warnings and instructions. -
Page 10: Safety Precautions - Service And Operation
Do not use if the unit has been dropped or the enclosure has been damaged. Contact InstruTech for return authorization and instructions for returning the product to InstruTech for evaluation. -
Page 11: Electrical Conditions
In cases where an equipment failure could cause a hazardous condition, always implement fail-safe system operation. For example, use a pressure relief device in an automatic backfill operation where a malfunction could result in high internal pressures if the pressure relief device was not installed on the chamber. InstruTech Page 8... -
Page 12: Gas Dependency
WARNING! The measurement value is gas dependent. The pressure reading applies to dry air, O , CO and . For other gases, the measurements have to be corrected. Refer to section 5 titled “Using the gauge with different gases” for a more details. InstruTech Page 9... -
Page 13: Installation
Remove the protective lid and install the product to the vacuum system following manufacturer’s recommendations for different flanges and fittings. Keep the protective lid for future maintenance.

Page 14: Electrical Installation
• Use an overall metal braided shielded cable. The connector must have a metal case. • Connect the supply common with protective ground directly at the power. • Use differential measurement input (signal common and supply common conducted separately). • Potential difference between supply common and housing ≤16 V (overvoltage protection). InstruTech Page 11... -
Page 15: Connector
Sensor on/off status is determined by open collector transistor (ground emitter) rated at 30 V max. V , 100 mA max. I Transistor off = Sensor off, Transistor on = Sensor on Wiring Diagram * Applying continuous ground activates the cold cathode sensor. InstruTech Page 12... -
Page 16: Setup And Operation
Connect power to the CCM502 using the designated pins 4 and 2 of the 9-pin D-sub connector. Alternatively, you can power the device by connecting InstruTech’s PS501-A power supply to the connector. Read this user manual in its entirety before activating the sensor. Refer to section 4.3... -
