4.7 General Notes for Using the System

Having designed a fully-functioning system, the only thing that remains is to keep it in good

health. The three biggest areas of risk to your system are at the following times:

• Connecting peripherals, disk-drives, printers, terminals and external

power sources.

• Adding or changing modules, address settings and locations, etc.

• Becoming complacent and not referring to the manuals when altering or

adding modules.

The way to reduce these risk is;-

• to check the electrical compatibility of all devices which you intend to

connect to your system, -

• to ensure that they are powered from the same mains supply branch

(phase) and grounded to the same reference point, -

• to shut down all power before making or breaking any connections to

piggyback(s)/VMOD-

2 configuration from

functioning.

If the VMOD-2 functioned before, and

has been reconfigured for a new appli-

cation/address/piggyback, steps 1 to 3

may help find/confirm the faulty area.

1) Repl ace pre vious

figuration and try for

corr ect fu nc tion of

VMOD-2.

2) Put piggyback into

other location on

VMOD-2 or if avail-

able onto another

VMOD/VMOD-2 mod-

ule and test for cor-

rect piggyback

function.

If the piggyback appears to function

correctly with other VMOD-2s or in

VMOD-2's other piggyback location the

problem could be damaged or burnt out

tracks which may not have used/

needed by the last piggyback fitted.

If the piggyback will not function with

other VMODs or in VMOD's other loca-

tion t he pr oblem is almost certa inly du e

to the piggyback or the application soft-

ware.
