    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 conditions. See section 3.3 to calibrate the 2852-LPS. Menu Flow Chart Background Information The control setup, diagnostics, and calibration are accessed using the display and keypad on the controller.

    Normal Screen 3.3.1 Site Calibration A factory pre-configuration and set-up has been defaulted into the 2852-LPS. As such, a user set-up is not required in the field. A basic calibration is only required. Be sure all the sensors are wired and placed in their proper location before calibrating.

  • Page 15: Setup, Alarms And Diagnostics

    Model: 2852-LPS User Manual Rev: 0.0 SETUP, ALARMS DIAGNOSTICS 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 4.0 pF. Increasing the pF value will increase the amount of liquid required to cause an alarm.

  • Page 16: 2852 Controller Diagnostics

    Model: 2852-LPS User Manual Rev: 0.0 3. Failsafe Failsafe typically means that the relay is held in an energized state when in a normal operating condition as opposed to an alarm condition. In an alarm condition, the relay de- energizes which is identical to when the instrument power is shut off. The rational is that the alarm condition should match the Power Fail condition.
