the RS-485 cable from the MCX-32 Controller to these terminals.
8.2 Operation
The Remote Display operates like the MCX-32 controller, with some important differences. The Remote
Display obtains most of the basic information from the controller, such as gas concentration, and alarm or fault
conditions. The Remote Display does not have the ability to set or change any of the alarm or fault settings.
Alarm and fault settings are set in the main controller, and the remote display can only display the status of
these alarms.
Like the MCX-32 Controller, the main screen of the remote displays eight channels of information at a time.
A group of ‘tabs’ are displayed near the top of the channel display area.
Each of these tabs displays
information for eight consecutive channels. Touching one of these tabs will cause the screen to display the
eight channels associated with that tab. In normal operation, the screen will loop through each tab displaying
all of the channels that are programmed into the controller. Each display of eight channels will remain on
screen for approximately ten seconds, and will then move to the next eight channels. If there are any alarms
active, the screen will remain on the display with the channel that is in alarm. If more than one channel is in
alarm and the channels are in different tabs, the screen will alternate between the tabs with active alarms.
Channel information is displayed in rows and each row provides the channel number, the channel description,
the current sensor reading, the gas type, and any active alarms or faults. Selecting a channel on the screen will
open the Channel Details Screen for that channel, and display all of that channel’s information.
