different way . The option are a follow :
Individual Channel Screens:
Show a elected channel in numeric and graphical format with engineering unit and channel number.
Pre → ← button to advance through each channel in thi format and to the following di play ….
Combination Screen:
Show all channel value in numerical format with channel number indicator .
Bargraph Screen:
Show all four input value a vertical bar graph with channel number .
Digital Status Screen:

In the example hown above, relay 2 and 4 are active, digital output 2 i active and digital input 4 i
active. Any active point will be indicated a hown.
From any of the tatu creen pre ‘ENTER’ to acce the ‘pa word creen’ and the programming
creen .
Enter u er elected pa word (factory default i zero) with the ↑ ↓ up and down key , then with
→ ← arrow button , move cur or to ‘next’
Pre ‘ ENTER’ to acce menu 1
In thi creen u er acce i provided for.
SCALE – Permit analog caling of each analog input
AOUT - Permit analog caling of each analog output
SETPOINTS - Permit et value for relay and digital output for each channel
DIN - Allow the u er to et the condition of a digital input
With the de ired item highlighted, pre ‘ENTER’ to acce the menu.
Scale:
Pre ‘ENTER’ to elect caling for channel 1 or u e the ↑ ↓ button to elect the de ired channel, pre
‘ENTER’ to acce caling for input 1.

10
U ing the → ← button , croll to ‘NEXT’, pre ‘ENTER’ to move to linearized creen.
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 QLC offer a 20 point linearizer which allow the u er to cu tomize the indicated di play for
20 point of input ignal. Thi feature i often u ed to read volume in a non-linear ve el uch a a
horizontal tank with domed end cap . a “ trapping table” mu t be created to allow the di play to be linear
with the re ultant non-linear input ignal.
If the u er required a non-linear di play, croll the cur or to “# OF POINTS” and u e the ↑ ↓ arrow to
elect the number of calibration point required, then elect ‘NEXT’ and pre ‘ENTER’ to continue.
Decimal oint Selection:
U e ↑ ↓ button to elect number of digit to be di played to the left of decimal point, croll to ‘NEXT’,
pre ‘ENTER’ and u e thi creen to enter the number digit to appear after the decimal point.
Scroll to ‘NEXT’ and pre ‘ENTER’ to proceed to the ‘Input Text’ creen.
Input Text:
When ‘SCALE MENU’ i complete the ‘INPUT TEXT’ menu i the la t menu in the caling proce .

11
Thi creen allow the election of everal engineering unit . With the cur or on the default value a
hown, pre the ↑ ↓ button to elect between ‘FEET OF WATER’
‘PSI’
‘GALLONS’
‘LITERS’
‘UNITS’
‘INCHES OF WATER’
Once the election i made elect ‘NEXT’ and pre ‘ENTER’. Proceed to:
Input Filter:
Input filtering i u ed to prevent ‘NOISY’ ignal from cau ing fal e alarm trip .
U e the ↑ ↓ key to change the amount of filtering applied to the input ignal. ‘O’ i no filter and ‘10’ i
high filter.
Once the election i made elect ‘NEXT’ and pre ‘ENTER’ to return to ‘Menu 1’.
The caling proce i now complete.
Select ‘NEXT’ and pre ‘ENTER’ to move to the analog caling creen.
Input Scaling to Engineering Units:
NOTE: Thi creen et what the Myriad QLC di play in it ‘default creen’ 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 .

12
A) With the cur or electing ‘INPUT = 4.00’ 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 ↑ ↓ button to change the
de ired di play for the previou ly elected input. Once complete, croll to ‘SAVE’, pre
‘ENTER’ to acce ‘INPUT SCALE 2’ creen.
Follow the tep outlined above to et the value of ‘input’ and ‘di play’ for input Scale 2.
When complete with cale 2, croll the cur or to the ‘DONE’ po ition and pre ‘ENTER’ to move to
programming creen for input #2 and repeat the above tep .
After etting all four input channel parameter , return to ‘MENU 1’ and elect ‘AOUT’ to program analog
output for each channel.
Analog Outputs:
U ing the button a de cribed previou ly, elect and adju t the value required for the analog output for
channel 1. Both the output value and the di play value for that output can be elected. When complete,
elect ‘NEXT’ and pre ‘ENTER’.
Thi will bring up the caling window for analog output 1 point 2 which i et a before. When complete
croll to ‘DONE’ and pre ‘NEXT’ to move to analog output etting for channel 2 – 4.
When complete, return to Menu 1 and elect ‘SETPOINTS’ to acce the etpoint menu.
Setpoints:
NOTE: Each channel i provide with one SPDT Form ‘C’ relay output and one 24 VDC digital output.

13
U ing the key a before, enter the ‘ON’ and ‘OFF’ value for both relay and digital output for each
channel.
Continue thi proce for all relay and digital output .
Return to Menu 1 and elect ‘DIN’ to program digital input .
DIN:
The Myriad QLC i provided with four digital input which when activated will ‘turn on’ their re pective
relay output , i.e. channel 1 digital input ‘on’ will turn on relay output 1.
The relay may be et to energize or de-energize by changing the election in the highlighted item from ‘Y’
(ye ) to ‘N’ (no).
Scroll and et all digital input a de ired and return to Menu 1 with the ‘EXIT’ key.
Menu 2:
Menu 2 i acce ed from Menu 1 by electing ‘NEXT’ and pre ing the ‘ENTER’ key.
eaks:

14
To re et a channel to the current value, pre the ↑ and ← imultaneou ly to clear channel 1, the ↓ and
← for channel 3, the ↑ and → for channel 2 and the ↓ and → for channel 4.
From the Menu 2 window, croll to ‘SETUP’ and pre ‘ENTER’ to acce the QLC’ global etting .
assword:
Enter a de ired pa word number with the ↑ ↓ key . When complete croll to ‘NEXT’ and ‘ENTER’ to
the creen croll window.
Once the password has been changed, make sure a record of the new password is
retained. Access to the programming menus requires a correct password.
Screen Scroll:
Selecting ‘ON’ in thi di play will cau e the ‘MAIN creen to croll continuou ly to permit equential
viewing. With thi value elected to ‘OFF’ the u er mu t pre ‘ENTER’ to view the ‘MAIN’ creen .
Once the de ired etting i elected, move to the next etting creen.
Screen Hold:
Set the time a creen will tay on the di play before crolling to the next creen.

Sensor Type:
The u er may choo e to elect the en or input a a digital or analog. Selecting digital will only allow the
QLC to turn ‘on and off’ a relay when the channel digital input i active. Mo t application will utilize an
analog en or.
When all programming i complete, u e ‘EXIT’ and ‘ENTER’ to return to the ‘MAIN’ creen .
MAINTENANCE AND TROUBLE SHOOTING
MAINTENANCE:
The Myriad QLC i a digital olid tate device which require no periodic maintenance.
Occa ional phy ical check of the unit hould be carried out for phy ical and mechanical ecurity of
mounting, terminal block , and electrical wiring.
TROUBLE SHOOTING:
 UNIT ‘LOCKS UP’ – Recycle power to the unit by removing AC power, waiting 10 econd and
reconnecting power.
.
 LCD di play goe dim or contra t i poor. Remove power from the unit, relea e the 2 rear mounting
crew and lide the unit forward in it ca e approximately 1 inch. On the left ide of the circuit
board i an adju table potentiometer. With a mall crewdriver adju t thi “pot” to allow alter the
contra t to the de ired amount. Return the unit to it normal po ition and ecure the rear crew .
 DISPLAY REMAINS AT ZERO OR SHOWS NO CHANGE -- If the di play remain at zero or
how no change but the proce i changing, check for D.C. voltage on the loop. With 2 wire
(4/20MA) in trument check with a D.C. voltmeter at the level in trument, by di connecting the level
in trument from it terminal ( AI1, AIC) and mea uring acro the e terminal with a D.C. voltmeter
for the pre ence of 24VDC.
NOTE: This should be done by using the user provided circuit breaker or fuse,
not by removing the power wires at the terminal block. Serious injury or death
can occur if contact is made with the incoming ac power.
WARNING

16
If D.C. voltage i pre ent, reconnect the negative wire of the upply and in ert a milliamp meter
between the po itive wire . The loop hould provide a ignal between 4 and 20 MA. If no current i
pre ent or the current exceed 20MA con ult the level in trument upplier.
If D.C. voltage i not pre ent check the u er upplied power upply or if u ing the Myriad upply
mea ure acro terminal 24VDC and AIC. If no 24VDC i pre ent con ult factory. If 24VDC i
pre ent check field wiring between the Myriad and the field device and recheck ‘SCALE’ function to
en ure correct etup.
