ERROR ERROR 4
PRIMARY / SECONDARY
COM
3 chirps per second once per
minute
Indicates a problem with the
communication between the two
gate operators in a bi-parting
(primary/secondary) gate system.
• Check the software versions
by pressing Reset or cycling
power. The version number
ashes on the display
(examples, h4.54 or h5.56).
• The software versions on
the Primary and Secondary
gate should be the same. If
not, upload current software
version using S.T.A.R.T. and a
PC laptop computer.
• Verify the Installer Menu item
DG (DUAL GATE) is set to DG2
in Primary and set to DG1 in
Secondary gate operator.
• Make sure the wires are
twisted and shielded. See Dual
Gate Wiring Connections on
page 79.
• Be sure the low voltage wire
runs, which include the bi-
parting gate communication
wires, are separate from
any high voltage wires runs.
Interference occurs if wire runs
are mixed or too close to each
other.
The error automatically clears
when the communication fault is
resolved.
