Internal error
Description
This alarm is issued when a problem arises within the internal circuit of the RG..N. In
the presence of this alarm, the RG..N will try as much as possible to proceed with
normal operation. It is up to the user to detect the presence of errors reported by
the RG..N and take action accordingly. When continuing operation with RG..Ns
reporting an internal error there is a risk that the messages are not correctly
received by the RG..N and/or replies will not be correctly received by the NRGC..
and/or main controller.
Diagnose
Confirm presence of 24V supply voltage on the NRG Controller US terminals.
Otherwise, replace the RG..N reporting an internal error.
