Figure 20. Connect a mag lock to the 450 MPS
with an external relay
Warning Light
: Connect a warning light to terminals
22 and 23 in the group labeled
W.LIGHT
in terminal
block J3. The terminals provide an output voltage of 30
VDC, maximum power 3 Watts. This output voltage
will power most 24 VDC warning lights.
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 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, S, E, EP, B, and C. B and C logic are appropriate for
guard station applications of the 412 Operator.
Refer to the operating logic tables earlier in these
instructions for more detail.
Switches 1, 2, and 3 control the operating logic
according to the following scheme:
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 earlier in this manual
and to the chart below for how to set DIP switch 4.
Gate Behavior
During Closing
Switch 4
Gate immediately
reverses its direction
when a reversing device
is triggered
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.

Activated on
Adjust the Potentiometers
The four potentiometers control the torque, the pause
time between opening and closing, the opening/closing
time of operation, and the leaf delay on closing.
