9 &10 provide 24VDC output when the
motors are running. Normally used to
power lock relay
11 & 12 provide 24 VAC for accessory
power (limited to 180mA).
13 & 14 provide 24VAC at all time
except when the gates reach its close
limits or the stop button is pressed
21 & 22 – UL BLOCK
indicator. Normally
open contacts that
changes states
(closes) during a UL
Block condition.
Intended for
connection of audible
and/or visual
indicator.
15 – COMMON (+)
16 – START input. It will start a cycle,
open or close depending on the last
operation or limit activation. It can also
be configured as a CLOSE only input
17- STOP command input (normally closed). Upon
activation, the gates immediately stop. It also
resets the controller to accept command inputs
after a UL BLOCK
18 – PHOTO input (normally closed). Photo beam sensors or other
obstruction sensing devices connect to this terminal. If triggered
during the close cycle the gate reverses. If triggered during the
open cycle the gate stops. The controller can be configured to
ignore this input during the open cycle.
20 – OPEN input.
19 – FAULT input.
Supervision circuit for
photo beam sensors.
6, 7 & 8 – MOTOR 1 (dual gate
operation) connections. Terminal 6 is
motor power +, 7 is motor power -, and 8
is limit switch input.
3, 4 & 5 – MOTOR 2 (single
gate operation) connections.
Terminal 3 is motor power +, 4 is
motor power -, and 5 is limit
switch input
23 - EXTERNAL
ANTENNA
24 - ANTENNA
GROUND (shielding)
WARNING:
Terminals 11 through 14 will switch to
24VDC output when the system is
running under battery back up.
