The following table displays the sequence of functions
accessible in BASIC PROGRAMMING:
BASIC PROGRAMMING
PAUSE TIME:
This has effect only when automatic logic is selected.
Adjustable from
to
secs. in one-second
increments.
Subsequently, display changes to minutes and tenths
of seconds (separated by a decimal point), time
is adjusted in 10-second increments, up to
minutes max. Thus, if the unit displays
, Pause
Time is 2 mins. and 50 secs.
Exit from programming and return to inputs status
monitoring.
8. Programming
To program the 455D Control Board, you have to access
“
PROGRAMMING
” mode. Programming is split into two parts:
BASIC
and
ADVANCED
.
LEAF 2 FORCE:
Adjusts thrust of Motor 2.
= minimum force
= maximum force (*)
LEAF 1 CLOSING DELAY:
Delays closing start of leaf 1 with respect to
leaf 2. Adjustable from to
minutes (see
Pause Time).
TIME LEARNING (see Section 10):
Enables the selection between “simple”
learning and “complete” (manual choice of
deceleration and stop points) learning.
+
≈
1 s.
Simple Learning:
>
3 s.
Complete Learning:
OPERATING LOGICS (see tab. 3/a - h):
(*) For hydraulic operators, set force to the maximum
level.
Basic Programming:
To access BASIC PROGRAMMING, press key

• Press and hold
F
, the unit will display the name of the first
function / parameter.
• When you release the key, the unit will display the param-
eter’s current value.
• Value can be modified with keys
+
and
-
.
• Press and hold
F
again, the unit will display the name of
the next function / parameter.
• When you reach the last function, press
F
to exit the pro-
gram, the display resumes monitoring input status.
• IMPORTANT: Make sure to exit programming mode other-
wise the changes will not be saved.

7. Operating Logics
This is a brief description of the main operating logics of the
system. For a complete description please refer to Table 3
• E (semi-automatic): This mode requires a command to
open and a command to close. A second command
during opening stops the gate. A second command
during closing reopens the gate.
• A (automatic): The gate opens on command and
automatically closes after the pause time. A second
command while opening is ignored; a second com-
mand during the pause phase interrupts the pause
time; a second command during closing reopens the
gate. A maintained open command will hold the gate
open.
• S (security): The security mode is like A logic except
that a second command during opening immediately
closes the gate. A maintained open command will not
hold the gate open.
• EP (semi-automatic, step by step): This mode requires
a command to open and a command to close. A
second command during opening or closing causes
the gate to stop. A third command then reverses the
previous motion of the gate.
• B (manned, pulsed): This mode is designed for guard
station use and requires a three button switch (pulsed)
to open, close, and stop the gate.
• C (manned and constant): This mode requires con-
stant pressure switches. One to open and one to close.
No pressure on a switch stops the gate.
