alignment. When this part of the alignment is fin-
ished, the display will automatically be returned to
ALIGN WITH DIV 1
. If during this step the screen
INPUT OUT OF RANGE
is encountered, check
the setup, including measuring the two inputs with
an ac voltmeter to ascertain that they are equal.
Repeat this step as necessary if the error screen
occurs.
7. Set the divider to 8-9-9-9-9-10.
8. Turn the encoder to
ALIGN WITH DIV 2
and press
the display.
9. The screen should now display
DIV 2 SET N
. Turn
the encoder until the N is Y and press the display.
At this point the display will request
PLEASE
WAIT while the unit begins the second part of the
input alignment. When this part of the alignment
is finished, the display will automatically be re-
turned to
ALIGN WITH DIV 2
. If during this step
the screen INPUT OUT OF RANGE is encoun-
tered, check the setup, including measuring the two
inputs with an ac voltmeter to ensure that the input
to the Model 451 (Pin 1 to Pin 2) is 40% of the
excitation (Pin 10 to Pin 14). Repeat this step as
necessary if the error screen occurs.
10. Set the divider to 6-4-9-9-9-10.
11. Turn the encoder until the display reads ALIGN
WITH DIV 3
and press the display.
12. The screen should now display
DIV 3 SET N
. Turn
the encoder until the
N
is
Y
and press the display.
At this point the display will request PLEASE
WAIT
while the unit begins the third and last part
of the input alignment. When it is finished, the dis-
play will automatically be returned to
ALIGN
WITH DIV 3
. If during this step the screen
INPUT
OUT OF RANGE
is encountered, check the setup,
including measuring the input with an ac voltmeter
to ensure that the input to the Model 451 (Pin 1 to
Pin 2) is 15% of the excitation voltage (Pin 10 to
Pin 14). Repeat this step as necessary if the error
screen occurs.
This completes the alignment of the Model 451. The user can return to the operate screen
by waiting 20 seconds for a “ time out” or by turning the encoder to
ALIGN EXIT , pressing
the display, turning the encoder to
OTHER EXIT
, pressing the display, turning the encoder
to
RETURN TO OPERAT
, and pressing the display.
