digits accordingly.

modify any parameter data. The least
significant digit of the parameter will
be changed by 1 for every INC or DEC
key entry. Upon the first INC or DEC
key entry, the “+/-” key, the decimal

The ENT, CLR, or ESC keys or one of the
menu keys may be pressed at any time
while modifying a parameter. The PCDU’s
reaction to these keys will be:
The ENT key is used to accept the new
data in the display. If this key is pressed,
the PCDU will exit the Setup mode (top
line will stop flashing), and compare the
number just entered against upper and
lower limits for that parameter. If the
number is beyond either limit, the PCDU
briefly displays “vLimv” or “^Lim^”,
followed by the current active value.
“vLimv” and “^Lim^” refer to lower and
upper limits, respectively.
Example:
If a value of 250 is entered as the new
desired set point while the lower limit is
600 for the TACH PULSES/REV, the
PCDU will display:
