WRN 3,02 Dual HHRC simultane-
ous inputs
WRN 3.07 Unrecoverable Commu-
nication Error

DECEMBER 2020
Table 9-3 Error and Warning Codes for HHRC
Meaning
Two HHRCs are sending
commands simultane-
ously.
If commands are not
conflicting, they will be
allowed (Base Board
decides).
If commands are con-
flicting, no action/move-
ment will be allowed by
the Base Board.
Warning appears
regardless of conflicting
or not conflicting to alert
operators that someone
else is trying to operate
the unit simultaneously
The display board in the
HHRC or PMRC has
power, but the Base
Board is not communi-
cating with it. It may be
caused by the HHRC,
Base Board, RCP
Board, or any other
device that is using the
RS-485 communication
lines in the system.
On an error, the Base
Board stops the pro-
gram, sends out the
error code to the display
devices and 'flashes' the
code on the Base Board
LED. Because one error
can cause others to fol-
low, the only code that is
displayed/flashed is the
first one that occurs.
Other errors may hap-
pen after that, but they
are not displayed.

OPERATING INSTRUCTIONS
Root Issue
Multiple users con-
trolling the mast
Defective HHRC or
defective base board.
Bad or improper connec-
tion in communications
link, or HHRC is not
properly powered.
Check continuity of the
data lines from the DC
power cable connector
to the HHRC connector.
Refer to System sche-
matic. Also check that
the shield in the junction
box has a good electri-
cal connection to the
electronics common at
one end or the other, but
not both
Replace HHRC or
HHRC Display pcb
