Communications Link Problems
If one of these messages appear on the Human Interface screen,
that Human Interface is not communicating with the unit.
Used With:
All Units with Local HI
Problem:
The Unit Mounted (Local) Human interface
has lost communications with the CGM. See
"Fail Diagnostic" for additional information.
Check:
Wiring between Unit Mounted (Local) Human
Interface and CGM. Verify crimping and polarity
of communications wiring. There should be no
loose connections or crimps on wire insulation.
OR
Used With:
All Units with Remote Human Interface
Possible Values:
Unit Number 1 through 4
Problem:
The Remote Human Interface has lost
communications with the unit whose number
is specified (#3 in this example).
Check:
Field/unit wiring between Remote Human
Interface and the IPCB on the unit number
specified. Also, verify wiring between the IPCB
and CGM of the unit whose number is specified.
Verify crimping and polarity of communications
wiring. There should be no loose connections
or crimps on wire insulation.
If one of these messages appear on the Human Interface screen,
the link is noisy or there is another Human Interface of the same
type on the link.
Used With:
All Units with Local HI
Problem:
Noisy Communications link or a second
Local HI has been installed on the link.
Check:
Wiring between Unit Mounted (Local) Human
Interface and CGM. Verify crimping of
communications wiring. There should be no
loose connections or crimps on wire insulation.
If a Remote HI was installed, verify that a
Local HI was not installed by mistake.
OR
Used With:
All Units with Remote Human Interface
Problem:
Noisy Communications link or a second
Remote HI has been installed on the link.
Check:
Field/Unit wiring between Remote Human Inter-
face and the IPCB and CGM. Verify crimping of
communications wiring. There should be no
loose connections or crimps on wire insulation.
Verify that no other Remote HI’s have been
connected to the same communications link/unit.
The following Troubleshooting chart lists possible Failure
Modes and:
1. The Diagnostic Displayed on the Human Interface’s LCD
screen and if it is a PMR, PAR, INFO or HO diagnostic.
2. The condition which caused the failure mode to occur or
the Reason for Diagnostic.
3. The UCM’s Reaction to the failure mode.
LOCAL HI COMMUNICATIONS LOSS
CHECK COMM LINK WIRING BETWEEN MODULES
REMOTE HI COMMUNICATIONS LOSS
CHECK COMM LINK WIRING TO UNIT NUMBER 3
Improper Human Interface Configuration
More than one Local HI on link
Improper Human Interface Configuration
More than one Remote HI on link
System Testing & Troubleshooting
Diagnostics
There are four types of diagnostics:
1. (PMR) Partial System Disable, Manual Reset
2. (PAR) Partial System Disable, Auto Reset
3. (INFO) Information Only
