Working with the DIAGNOS Function

Overview

The DIAGNOS function displays sensor data and status information useful to a service technician for troubleshooting various fault conditions. Explanations of the data shown in these screens are given below.

Keypad Functions

From the Data Display screen, use the Keypad buttons to place the arrow (>) on the display next to the DIAGNOS function. Then press ENTER to display the first of two Diagnostic screens.

Press the Up Arrow Keypad button to toggle between the First and Second Diagnostic screen.

First Diagnostic Screen

In the first diagnostic screen, the user can toggle between displaying the Bench Voltage / Noise and Detector Temperature / Box Temperature by pressing the Right Arrow Keypad button.

Bench Voltage – This is the current peak-to-peak output of the IR detector. In the absence of refrigerant this value can range from 3.90000V to 4.50000V.

Noise – The Noise value is a 16 point running average of the noise portion of the IR detector’s output. This reading is valuable mainly when refrigerant is NOT present.

Detector Temperature – This is the current detector temperature in °C. Box Temperature – This is the current internal enclosure temperature in °C.

Fault Code – Current fault code. A value of <0000> indicates that no faults are being detected. Manifold Pressure – Current manifold pressure in psia.

Purge Valve Asterisk (∗) – The purge valve can be opened and closed by pressing the Left Arrow Keypad button. An asterisk appears on the display when the purge valve is open.

Second Diagnostic Screen

PPM Level – Parts Per Million Level is the current detected gas level, and is the volume concentration referenced to standard temperature and pressure.

Average Absorption Unit – This is the optical absorbency. In the absence of refrigerant the absorbency is 0.00000 au. When sampling refrigerants, its value varies proportionally with the refrigerant concentration.

µMoles/Liter – This is the absolute concentration in micro-moles per liter of refrigerant.

Detector Voltage – This is a running average of the IR detector’s bench voltage as displayed in the First Diagnostic screen.

Purge Valve Asterisk (∗) – When viewing the diagnostic screen, the purge valve can be opened and closed by pressing the Left Arrow Keypad button. An asterisk appears on the display when the purge valve is open.
