HX-VP420 Series Installation Guide

Model HX-VP420

The 4 to 20 mA output transducer is a 2-wire,

loop pow ered de vice. The transducer, pow er

supply, and cur rent monitor must be con nect ed

in series as illustrated above.

The minimum supply voltage is a function of

total loop resistance. It may be calculated us ing

the formula:

V(Min.)= (0.02 x Load Res.) + 9 VDC

It may also be determined from the ac com -

pa ny ing graph, shown at right.

When mounting, insure that the baseplate of the

transducer is grounded to earth ground. For best

noise immunity, use twisted pair

an gu lar position transducers, ro tate shaft) to the

desired zero po si tion (must be with in 0% to 30%

of range). Adjust the Zero con trol so that the

output cur rent is 4 mA. Then extend the ca ble (on

angular position trans duc ers, ro tate shaft) to the

de sired max i mum position (must be within 80%

to 100% of range). Ad just the Span con trol for

zero set ting and adjust if nec es sary. Re check the

Span setting and readjust if nec es sary.
