Operations Manual 3
CM1(N) Display
The CM1(N) master controller uses a 40-character, 2-line Liquid
Crystal Display (LCD). When the IRC-3 network is powered up, the
following is displayed:
01:01:01 AP0000 DP0000
• Time is displayed in 24-hour format.
• AP 0000 (Active Points): After the system has completed an initial
poll of devices/zones, “AP 0000“ indicates the total number of
active network points.
• DP 0000 (Disabled Points): Indicates the total number of disabled
devices/zones in the network. The “DP XXXX” display normally
indicates “0000” unless the program (or operator) has disabled these
points. If devices/zones have been disabled, “DP XXXX” indicates
the number of disabled devices/zones.
• The second line of the display is blank.
• MW XXX (Messages Waiting)
In addition to the above display, trouble status messages will flash
when a certain problem exists. The message will be displayed to the
right of the Disabled Points (DP). This can be extremely helpful to
troubleshooting a problem. These same messages will also be displayed
under Status when the Test/Status button is pushed. The possible
message conditions are:
• “COM0 - ZAS-2 Communication Flag
• “RES0” - Reset in Progress
• “ZAS0” - Internal Trouble
• “MPE0” - Mapping Disabled
• “PRG0” - Programming in Progress
• “GND0” - ZAS-2 Ground Fault
• “LIN0” - Class A Fault
• “MAP0” - ZAS-2 Map Fault
01:01:01 AP0000 DP0000 ZAS0
“ZAS0” indicates that an internal trouble exists with the ZAS card.
Other messages will be displayed when other conditions exist.
