INTRODUCTION:
The Sigma Myriad LC1 (Level C ntr ller) is a micr pr cess r based, state f the art, level c ntr ller
ffering unmatched perf rmance and full user c nfigurability.
The LC1 is used with a primary level measuring device wh se utput signal is c mpatible with c mm n
anal g utputs 4/20MA, 0-5VDC, 1-5VDC, and 0-10VDC.
Level indicati n is displayed in b th numeric and graphic f rmat n the LC1’s graphic LCD display al ng
with the current status f the unit’s 4 digital utputs.
All aspects f the unit are user c nfigurable thr ugh the ‘plain English’ menus and c mbinati ns f the
5 user data key push butt ns.
Available in 2 styles f m unting, ¼ DIN (4” x 4” n minal) and wall m unted Nema 4X encl sures, the
Myriad LC1 is suitable f r installati n in all industrial envir nments.

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 ( A/240VAC resistive).
WARNING
Hazardous voltages are present within the enclosure.
Installation or service should only be carried out by trained
personnel.
PROGRAMMING & SETUP
The Myriad LC1 utilizes a ‘plain English’ menu driven setup screens which are intuitive and easily
underst d.
Fr m the default screen (Fig. 1), push the ‘Enter’ butt n t enter the passw rd pr tected menus.
Default

ENTER
Enter user selected passw rd (fact ry default is zer ) with the up and d wn keys, then with and
arr w butt ns, m ve curs r t ‘next’
Press ‘ENTER’ t access menu.
NOTE: Selecting ‘VIEW’ with the and and then pressing ‘ENTER’ will all w the user t
step thr ugh all LC1 settings with ut having the ability t change any parameter.
Parameter changes may nly be carried ut after entering the user selected passw rd as described ab ve.
INPUT RANGE SELECTION
With the ‘SCALE’ selecti n highlighted by the curs r, press ‘ENTER’ t access the input scale menu.

CPU Status
Use the Up/D wn arr w butt ns t select the desired anal g input range. NOTE: INPUT TYPE MUST
BE CO-ORDINATED WITH INPUT SELECTOR SWITCH LOCATED ON THE BOTTOM OF
THE CIRCUIT BOARD (See Appendix ‘A’).
NOTE: If the application is linear between minimum input signal and maximum input signal, i.e.
“2 point”, then scroll the cursor to ‘NEXT’ and press ‘ENTER’ to continue the scaling process.
Note on non linear inputs
The Myriad ffers a 20 p int linearizer which all ws the user t cust mize the indicated display f r 20
p ints f input signal. This feature is ften used t read v lume in a n n-linear vessel such as a h riz ntal
tank with d med end caps. a “strapping table” must be created t all w the display t be linear with the
resultant n n-linear input signal.
If the user required a n n-linear display, scr ll the curs r t “# OF POINTS” and use the arr ws t
select the number f calibrati n p ints required, then select ‘NEXT’ and press ‘ENTER’ t c ntinue.
DECIMAL POINT SELECTOR SCREEN
The curs r will be p siti ned ver the decimal c unt wind w, use the Up/D wn arr w butt ns t
raise r l wer the unit number t the left f the decimal p int. (The example sh wn in this wind w will
change with y ur selecti n.)
Use the butt ns t m ve the curs r t the number behind the decimal p int and the
Up/D wn butt ns t change this selecti n. Once again the example will change t c nfirm y ur
selecti n.
Use the butt ns t highlight the ‘NEXT’ selecti n and press ‘ENTER’ t access the Input
Scale Screen.
INPUT SCALING TO ENGINEERING UNITS
NOTE: This screen sets what the Myriad LC1 displays in its ‘default screen’ f r the selected input.
The example sh wn ab ve will display 0.0 units when the input is 4.00 MA. B th the input and the
display at that input can be changed f r different requirements.
A) With the curs r selecting ‘INPUT = 4.00’ use the butt ns t change the input value f r the
required displayed value.
B) Use the butt ns t m ve the curs r t the ‘display’ value and the Up/D wn butt ns t change
the desired display f r the previ usly selected input. Once c mplete, scr ll t ‘SAVE’, press
‘ENTER’ t access ‘INPUT SCALE 2’ screen.
F ll w the steps utlined ab ve t set the values f ‘input’ and ‘display’ f r input Scale 2.
When c mplete with scale 2, scr ll the curs r t the ‘DONE’ p siti n and press ‘ENTER’ t m ve t the
“ENGINEERING UNITS” selecti n screen.
ENGINEERING UNITS SELECTION:
When ‘Scale Menu’ is c mplete the ‘INPUT TEXT” menu is the last menu in the scaling pr cess.
This screen all ws the selecti n f several engineering units. With the curs r n the default value as
sh wn, press the Up/D wn butt ns t select between ‘FEET OF WATER’
‘PSI’
‘GALLONS’
‘LITERS’
‘UNITS’
Use the ↑ ↓ keys t select the desired engineering units then with the → ← keys, highlight ‘NEXT’ and
press ‘ENTER’ t access the “display filter” screen.
