Interface is not communicating properly with the unit.
LOCAL HI COMMUNICATIONS LOSS
CHECK COMM LINK WIRING BETWEEN MODULES
Used With: All Units
Note: The “Local HI” (Local Human
Interface) is located at the unit.
Problem: The Local Human Interface has lost communications
with the RTM module. See “Fail Diagnostic” for additional
information.
Check: Wiring between the Local Human Interface, unit mounted
communications terminal block, and RTM. Verify crimping and
polarity of communications wiring. There should be no loose
connections or crimps on wire insulation. See the appropriate unit
wiring manual for additional information.

Used With: Units w/Remote Human
Interface Option
Possible Values:
Unit Number: 1, 2, 3, 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 RTM 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.
Note: If one of the following 2 screens appear, the
communications link is marginal or there is another Human
Interface of the same type on the link.
IMPROPER HUMAN INTERFACE CONFIGURATION
MORE THAN ONE LOCAL HI ON LINK
Used With: All Units
Problem: Noisy Communications link or a second Local HI has
been installed on the link.
Check: Wiring between the Local Human Interface, unit mounted
communications terminal block, and RTM. Verify crimping and
polarity of communications wiring. There should be no loose
connections or crimps on wire insulation. See the appropriate unit
wiring manual for additional information. Also, if a Remote HI was
installed, verify that a Local HI was not installed by mistake.
