Note
: The behavior of the warning light varies
according to the logic you have set:
Logics A, S, E, EP, and B
: The warning light
is on steadily during opening and the pause
phase. During closing, the light flashes.
Logic C
: The warning light is on steadily
during opening and flashes during closing.
Set Other Operating Controls
WARNING
! Turn off the main power before
you make any electrical connections or set any
switches inside the control panel box.
Note
: Some DIP switch assemblies are labeled
differently depending on their date of
manufacture. OPEN indicates
off
and ON
indicates
on
.
You need to set DIP switches and adjust some
potentiometers on the control panel for your gate's
operation. The 450 MPS Control Panel has 5 DIP
switches and 4 potentiometers that control a wide range
of functions.
Set DIP Switches
Switches 1, 2, and 3 (Operating Logic)
: The 450 MPS
Control Panel offers six operating modes:
•
A (automatic)
•
S (security)
•
E (semi-automatic)
•
EP (semi-automatic, step by step)
•
B (manned, pulsed)
•
C (manned and constant)
Refer to the operating logic tables later in these
instructions for more detail.
Switches 1, 2, and 3 control the operating logic
according to the following scheme:
DIP Switch
Logic
1 2 3
A off off off
S on off off
E off on off
EP on on off
B on on on
C off off on
Switch 4 (Reversing Device Behavior on Closing)
:
Refer to the operating logic tables later in these
instructions and to the chart below for how to set DIP
switch 4.
Gate Behavior
During Closing
DIP Switch 4
Gate immediately
reverses its direction
off
Gate stops and reverse its
direction when reversing
device is no longer
triggered
on
Switch 5 (Reversing Stroke)
: Some electric locks
require a reversing stroke to disengage the lock. If your
lock requires this reversing stroke, set DIP switch 5
according to the following chart.

Adjust the Potentiometers
The four potentiometers control the torque (or
pressure), the pause time between opening and closing,
the opening/closing time of operation, and the leaf delay
on closing.
Torque (Pressure)
:
The torque (or pressure)
potentiometer on the 450 MPS must be turned all the
way clockwise for the 750 Operator. The potentiometer
controls voltage to the operator, which can affect the
life of the operator’s motor. The torque/pressure
potentiometer cannot be used to adjust the operator’s
hydraulic operating pressures.
Caution
: Failure to turn the torque/pressure
potentiometer to maximum in the clockwise
direction jeopardizes the life of the motor of
your operator.
WARNING
! Adjust the operating pressure on
the 750 Operator only by means of the
hydraulic bypass valve screws. See pages 18
and 24.
