Watlow VPAC-AT Remote Mount Transformer Manuel d'utilisateur télécharger pdf (Page 2)

Note:

The controls transformer must

be on the same phase as the

load. See wiring diagram. All

hot lines to the transformer

should be fused at 1 amp with

the proper line voltage.

For manual control, a 1KΩ

potentiometer may be connected

to the AT card input terminals.

Watlow offers a Manual Control

Kit, P/N 08-5362. Using this

potentiometer requires removing

the 5KΩ, R2 resistor for higher

impedance.

Bias and gain adjustment is

required when changing from 4-

20mA input to a manual control

input or a voltage input.
