- The MN Converter (CMS-MNG-E) has a built-in remote error notification function.
When an error occurs in an air conditioning unit, the remote error notification function allows previously
registered destinations to be automatically notified of the error via telephone lines.
To use the remote error notification function in the MN Converter (CMS-MNG-E), you must first specify
the remote error notification settings from the Maintenance Tool.
The MN Converter (CMS-MNG-E) has the following 2 modes:
(1) Maintenance mode
In this mode, the MN Converter can only be used as a normal converter.
(2) Remote error notification mode
This mode allows both the normal MN Converter functions and the remote error notification
function to be used.
Use the Maintenance Tool to switch between these 2 modes.
To use the remote error notification function, connect the MN Converter (CMS-MNG-E) to a modem via the
RS-232C port and then connect the modem to the telephone outlet, as shown in the figure below.
For details, refer to the Installation Manual of MN Converter (CMS-MNG-E).
