ALERT ALERT 21
DRIVE TRIP
2 chirps per second every 15
seconds
Gate travel will not occur until
the alert is cleared. Any open
or close command resets the
alert and starts the gate moving,
unless the VFD is experiencing
a fatal error. If you cannot clear
the error alert by pressing the
open or close button, contact
HySecurity.
ALERT ALERT 22
INTLOCK FAILURE
2 chirps per second every 3
seconds
Appears when the RS-485
communication connection is
lost for more than 5s between
interlocked (dual gate) or
sequenced gate operators.
1. Check cable connections
and wiring. Make sure
both operators are working
properly and have compatible
software versions. The
alert auto clears when
communication between the
two operators is restored.
2. If the operator on site is a
singular gate and the display
code ALERT 22 appears,
access the Installer Menu.
Verify the Installer Menu
items: DG (Dual gate) and SG
(Sequential gate) are both set
to zero.
