Page 11: Startup And Calibration
The unit is pre-configured and tested at the factory. However, a quick field calibration is required after power up to tune the sensor to the installation conditions. See section 3.3 to calibrate the 2852-PCD. Menu Flow Chart Background Information The control setup, diagnostics, and calibration are accessed using the display and keypad on the controller. -
Page 12: Data Entry
Normal Screen 3.3.1 Site Calibration A factory pre-configuration and set-up has been defaulted into the 2852-PCD. As such, a user set-up is not required in the field. A basic calibration is only required. Be sure the sensor is wired and installed into it’s final location before calibrating. The process must be operating so that the sensor face is looking at normal process conditions. -
Page 13: Setup And Alarms
Model: 2852-PCD User Manual Rev: 2.1 SETUP ALARMS 2852 Controller Setup The 2852 controller has the following Setup parameters: 1. Sensitivity The sensitivity determines the amount of pF change required to cause an alarm. The factory default setting is 1.0 pF. This is the most sensitive setting. Increasing the pF value will increase the amount of product required to cause an alarm. -
