Main menu: Diagnostics screen
Diagnostics
The Diagnostics screen allows you to monitor all of the analog and
discrete inputs to the Vapor-logic
3 control system. Use the Next and
Back to scroll through the input signals on your system.
The Diagnostics screen is useful when troubleshooting. For
example, to troubleshoot the RH signal input, select RH Signal
on the Diagnostics screen. The screen displays the input signal in
milliamps and what this signal translates to in terms of relative
humidity. You then can verify that the input is working correctly.
The table below lists available Diagnostic menu items (depending
on system options and type) with normal values and/or ranges.
