OX-AN R-134a Leak detection Monitor V1.3 2. RelayContainer.sxml 3. SensorContainer.sxml 4. SystemSettings.sxml Note that “restoring system defaults” will overwrite these files. 2.3 Signal Board PIC18F2550 Firmware The firmware located within the embedded boards can only be changed by replacing the PIC processor with a pre-programmed PIC. -
Page 5: Sensor Value Tab
OX-AN R-134a Leak detection Monitor V1.3 3.1 Sensor Value Tab Fig 2.0 Sensor Values Tab During normal running the Monitoring Screen (Fig 2.0) displays the location text, alarm levels, sensor value and isolate status for both R-134a and O sensors. This is the normal viewing screen. -
Page 6: Outputs Tab
OX-AN R-134a Leak detection Monitor V1.3 3.2 Outputs Tab The Outputs tab, Fig 3.0, displays the current state of the relay outputs connected to the system. During normal running the tab shows the location text and relay state for all relays. -
Page 7: Diagnostics Tab
OX-AN R-134a Leak detection Monitor V1.3 3.3 Diagnostics Tab The Diagnostics tab provides a visual and textual indication of the connected Sensor and Relay boards. It is important the number of connected boards is correctly specified in the system settings. -
