Adjustments:
There are three types of adjustments on the Magnum Control Board. These are; a slide switch,
eight potentiometers and one selector (dip) switch. See Figure 2 for the location of these adjustments.
Slide
Switch
-
The slide switch can be used to select the appropriate mode of the Magnum IV control.
The modes available are: UPPER POSITION - Upper position is for GT500 (Low Energy Operator)
LOWER POSITION - Lower position is for GT300/400 (Standard Full
Automatic Operator).
By adjusting the slide switch , the Magnum board can control a Standard Swing full automatic operator or
Low Energy operator. Leaving the slide switch in the upper position reduces power to the motor thereby
allowing for the system to be adjusted to ANSI 156.19 Low Energy Standards. If it is desirable to increase
opening power on a GT-500 or GT-710, move the slide switch to the lower position. For the latter, final
installation must conform to ANSI 156.19.
The amount of energy stored in the door and imparted to an object on impact is determined by both the
weight and speed of the door. NABCO ENTRANCES INC. recommends setting opening and closing
speeds as slow as owners will accept, AND below the maximums stated by ANSI.
The settings on the controller will vary slightly as the voltage supplied to the unit varies due to fluctuations
in building and electrical supply loads. To allow for variations, the manufacturer recommends adding 1
second to ANSI’s minimum opening or closing times. Use a stopwatch for assistance.
Potentiometers
–
There are eight potentiometers located on the control board. Use a small #0 Cross point
or Phillips screw-driver to adjust each potentiometer. Don’t touch other parts of the board with the
screwdriver. This could damage the electrical circuitry. Adjust potentiometers clockwise to increase the
parameters (speeds, stops, delays, etc.), counterclockwise to decrease the parameters. Wait at least 5
seconds before testing the change. Recommended start settings correspond with positions on a clock with 12
o’clock at the top. The settings are a starting point. They are standard field approximations that might need
to be adjusted for a specific situation.
Selector (Dip) Switches –
There is one bank of four switches located on the control board. The screwdriver
can be used to toggle the switches on and off. Do not use a pencil. Note that the edge of the switch bank
closest to the transformer is the “Off” position.
