MAINTENANCE AND TROUBLE SHOOTING
MAINTENANCE:
The Myriad LC1 is a digital s lid-state device which requires n peri dic maintenance.
Occasi nal physical checks f the unit sh uld be carried ut f r physical and mechanical security f
m unting, terminal bl cks, and electrical wiring.
TROUBLE SHOOTING:
 UNIT ‘LOCKS UP’ – Recycle p wer t the unit by rem ving AC p wer, waiting 10 sec nds and
rec nnecting p wer.
.
 LCD display g es dim r c ntrast is p r. Rem ve p wer fr m the unit, release the 2 rear m unting
screws and slide the unit f rward in its case appr ximately 1 inch. On the left side f the circuit
b ard is an adjustable p tenti meter. With a small screwdriver adjust this “p t” t all w alter the
c ntrast t the desired am unt. Return the unit t its n rmal p siti n and secure the rear screws.
 DISPLAY REMAINS AT ZERO OR SHOWS NO CHANGE -- If the display remains at zer r
sh ws n change but the pr cess is changing, check f r D.C. v ltage n the l p. With 2 wire
(4/20MA) instruments check with a D.C. v ltmeter at the level instrument, by disc nnecting the level
instrument fr m its 2 wires and measuring acr ss these 2 wires with a D.C. v ltmeter f r the presence
f 24VDC.
If D.C. v ltage is present, rec nnect the negative wire f the supply and insert a milliamp meter
between the p sitive wires. The l p sh uld pr vide a signal between 4 and 20 MA. If n current is
present r Y current exceeds 20MA c nsult the level instrument supplier.
If D.C. v ltage is n t present check the user supplied p wer supply r if using the Myriad supply
measure acr ss terminals 24VDC and A/C. If n 24VDC is present c nsult fact ry. If 24VDC is
present check field wiring between the Myriad and the field device and recheck ‘SCALE’ functi ns t
insure c rrect setup.
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.
