Page 14: 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 and cable condition. See section 3.3 to calibrate the 2852-DPM . Menu Flow Chart Background Information The control setup, diagnostics, and calibration are accessed using the display and keypad on the controller. -
Page 15: Data Entry
Normal Screen 3.3.1 Site Calibration A factory pre-configuration and set-up has been defaulted into the 2852-DPM. As such, a user set-up is not required in the field. A basic calibration is only required. For the initial calibration, ensure that the pipe is full of liquid. For Liquid to Liquid applications, the highest di-electric liquid should be in the pipe during calibration. -
Page 16: Setup And Alarms
The factory default is 0 to provide an immediate and active response. 2852 Controller Alarms The two relays on the 2852-DPM operate together. The follow parameters are available as a common setting to the two relays: 1. Delay. Minimum time in seconds for an alarm to exist before the relays change to an alarm state. -
