applications. Most of these parameters alter the operating characteristics. There are default

parameters for general purpose usage, but the actual programming of these parameters

for any application is the responsibility of the user.

The unit is shipped from the factory with the default parameters unless it is shipped as

part of a system. If it is part of a system, it will be shipped with parameters which will be set

up according to the information which POWERTEC has available about how it will be used.

If a special setup has been requested, or is required, that is how it is shipped. Table I on page

14 and Table 1A on page 20 contain a list of the default parameters, which may be entered

from the table. After a DIGIMAX

to enter all parameter values into Tables I (page 14) and 1A (page 20) to maintain a record.

PARAMETER ACCESS

Access to the parameter list requires the knowledge of one of the two security codes:

a master maintenance code (printed at the end of this manual on a tear out page), and an

operator password (parameter #21). The maintenance code is built into software and cannot

be changed, except by the factory. The operator password may be changed at will by anyone

with access to the parameter tables.

Before following this procedure, read section 2.0 (ORIENTATION) of this manual.

Access to the parameters is gained by the following procedure:

It is not necessary to enter any leading zeroes. Enter 12, if that is the code. It is not

necessary to enter 00012, although that will work. The number "0" is a legitimate code. You

must press at least 1 digit to enter a code.

If the number has been incorrectly entered, the display will return to the display mode

it was in before the PGM/CLR button was pressed. If the number is correctly entered, the

display will show a "P-nn" ('nn' is a number from 1 to 41). That number will be the parameter

currently available for review. If this is the first access since power was applied, parameter

#1 will show (a "P-01" will be displayed). If there was a previous access since the last time

power was applied, the parameter visible when setup mode was exited will be showing.

If the DIGIMAX

(parameter #16 is set to "0") the display will flash "Err 15" (see page 31). Press the PGM/

CLR button again, and, if the display goes blank, press the PGM/CLR button to restore the

display. Wait until the RUN command is off before attempting to change parameters. The

parameters may be accessed as soon as the RUN input is off, even during deceleration.

If frequent access to the parameters is necessary, change parameter #16 to "1" to allow

access to the parameters while running, and change parameter #21 to "0" so that access to

the parameters may be gained very quickly by pressing the PGM/CLR button, "0", and the

ENT button..

Moving up in the parameter tables (#1 to #2 to #3, etc.) is accomplished with the UP

button. When parameter #41 is reached, pressing the UP button will roll over to parameter

#1. Moving down in the parameters (#10 to #9 to #8, etc.) is accomplished with the DN

button. Pushing DN when parameter #1 is showing will roll over to parameter # 41.
