No Output Voltage

Check power source beakers or fuses.

Check input switch (on portable units).

Check continuity between input terminals, and also between output

terminals.

Transformer Operating Temperature

The transformer used in these regulators is designed to operate at

high flux density, and hence, relatively high temperatures. After

connection to line for a half- hour or so, the transformer core

structure may be too hot to touch with the bare hand. This is normal

and should not be a concern.

Note

In case the regulator is operating but does not appear to have the correct

output,

it is very helpful to apply the following test

Disconnect the working load.

Connect a dummy load of lamps, heaters, or other resistive load

substantially equal to the full-load rating of regulator, directly across

its output terminals.

Measure the output voltage of the regulator using a true RM type

voltmeter directly across its output terminals.

This test will usually establish whether the apparent poor performance is due

to a fault in the regulator or to some peculiarity of the working load.

Factory Test and Inspection

If the field test suggested earlier indicated that the regulator itself may be

faulty, a full report of the difficulty should be communicated to the place of

purchase. The Authorized Sola/Hevi-Duty Distributor may then suggest

further helpful field tests or authorize return for inspection at once. A Return

Authorization Number will be issued. This Number must appear on the

outside of the shipping container, otherwise the shipment will not be

accepted.
