Changing a
Parameter
• Press the ENT key. The PCDU now
displays:
This display shows the function description
on the top line. The present value, units,
and the function number are displayed on
the bottom line. The “P” before the
function number indicates that the item in
the display is from the PRM menu. By
pressing the INC or DEC key, the operator
can view the next or previous parameter.
Example:
The operator from the previous example
wants to change the value for the TACH
PULSES/REV. After accessing the desired
parameter (see “Viewing a Parameter” on
page 10):
• Press the ENT key to allow the
parameter presently in the display to
be changed. This Setup mode is
active when the top line of the
PCDU display is flashing.
The parameter in the display may be
changed in one of two ways:
1. Up to five digits plus a decimal point
may be pressed. The “+/-” key may
also be pressed. When this key is used,
the left-most character (sign digit) will
change sign. As soon as the first digit
key, “+/-” key, or decimal point key
is detected, the INC and DEC keys will
be ignored. The PCDU recognizes
when decimal points are appropriate,
based on the PAC diagram, and handles
TACH PULSES/REV
