The range selector switches located on the bottom of the circuit
board are factory set. If a field change of input type is required see
Appendix ‘A’. Do not apply an input signal that is not coordinated with
range switches or the unit may be damaged.
CAUTION
!
All electrical wiring must be in accordance with all local state and national
codes that apply.
Do not exceed the rated current of the D.C. power supply (100MA) or the
form ’C’ relay outputs (5A/ 40VAC resistive).
WARNING
Hazardous voltages are present within the enclosure. Installation or
service should only be carried out by trained personnel.

MENU SCALE
U e the → ← button to highlight ‘SCALE’ and pre ‘ENTER’.
U e the ↑ ↓ arrow button to elect the de ired analog input range. NOTE: INPUT TYPE MUST
BE COORDINATED WITH INPUT SELECTOR SWITCH LOCATED ON THE BOTTOM OF
THE CIRCUIT BOARD (See Appendix ‘A’)
The ‘DPC’ doe not include linearization of the input ignal. The di play i linear over the 2
point elected.
NOTE: Highlight ‘NEXT’ and pre ‘ENTER’ to advance to the next creen.
DECIMAL POINT SELECTOR SCREEN
The cur or will be po itioned over the decimal count window. U e the ↑ ↓ arrow button to rai e
or lower the unit number to the left of the decimal point. (The example hown in thi window will
change with your election.)
U e the → ← button to move the cur or over the number behind the decimal point and u e
the ↑ ↓ button to change thi election. Once again, the example will change to confirm your
election.
U e the → ← button to highlight the ‘NEXT’ election and pre ‘ENTER’ to acce the Input
Scale Screen.

INPUT SCALING TO ENGINEERING UNITS
NOTE: Thi creen et what the Myriad DPC di play in the main di play for the elected
input. The example hown above will di play 0.0 unit when the input i 4.00 MA. Both the input
and the di play at that input can be changed for different requirement .
A) With the cur or electing ‘4.00’ (or the zero value of the elected input) u e the ↑ ↓ button to
change the input value for the required di played value.
B) U e the → ← button to move the cur or to the ‘di play’ value and the Up/Down button to
change the de ired di play for the previou ly elected input. Once complete, croll to ‘SAVE’,

SPEED SCALE
The ‘level’ value will be highlighted, u e the ↑ ↓ button to change the level point at which the
peed of the drive ( elected in the next block) i reque ted. In the example above, the drive will
be at 50% peed when the level i 30 inche .
Select a value of drive peed and level a de cribed above and croll to ‘EXIT’ to ave the
value elected and move to analog output 4 creen.
NOTE: When inverting the output direction (as in a pressure application), the speed on
scale one must be lower than the speed on scale . For example, to invert the default
values that are shown here, use the following settings:
Scale 1: Level = 100, Speed = 50%
ANALOG OUTPUT 4 (ANLOUT4) NOTE: Analog output 3 is a nonadjustable
retransmitted signal which ‘mirrors’ the analog input signal.
NOTE: Analog output 4 i retran mitted output which can be caled to any value of the di play.
With the di play value highlighted, u e the ↑ ↓ button to elect a di play value at which a
electable output occur . U e → ← button to move to the output value for the previou ly
