Preliminary Information

About the Control

NetMaster on the commercial washer is an advanced,
programmable computer that lets the owner control
most machine features by pressing a sequence of
SELECT CYCLE and SELECT WASH TEMP pads.
Refer to Figure 1.

NetMaster allows the owner to program custom
cycles, set vend prices, retrieve audit information,
program and run diagnostic cycles, and program
special vend features. Washers shipped from the
factory have a default cycle and wash temperature
setting of PERM PRESS, WARM built in. However,
the owner can change the default cycle, or any cycle,
as needs permit.

IMPORTANT: In the event of a power failure,
NetMaster will not have to be reprogrammed. It is
designed with a memory system that will remember
how it was programmed (for a minimum of six
years) until the electrical power is restored.

IMPORTANT: It is extremely important that the
washer has a positive ground and that all mechanical
and electrical connections to NetMaster are made
before applying power to or operating the washer.

Glossary of Terms

The following are a few terms and abbreviations to
learn. These are referred to throughout the instructions.

VFD - Vacuum Fluorescent Display.

This term refers to the window area of the
control that displays words and values.

LED - Light Emitting Diode.

This term refers to the lights on the keypads
and status words of the control.

Power Failure Recovery

If a cycle is in progress and the power fails, the cycle
status is saved in memory for a minimum of six years
without power. When the power recovers, the washer
will resume into the previously active cycle if so
programmed by the owner.

The owner may program a special feature called
POWER FAIL RESET which sets a maximum power
failure duration. To program this feature, refer to
Programming NetMaster, option 25.

If the length of the power failure is greater than the
POWER FAIL RESET time, the control will end the
cycle and the display will revert back to the ready
mode. If the washtub is full of water, the control will

move to the Rinse Spin cycle and prompt the user to
press the START pad. Once the START pad is
pressed, the control will spin out the cycle.

Communications

NetMaster may be programmed manually, by the
Micro-Wand IIIE™, by the Network, or by a Smart
Card.

Infra-red Communications
(Optional)

The Micro-Wand allows the owner to program and
retrieve information from NetMaster without touching
the keypad. The Micro-Wand greatly expands the
programming options available to the owner. However,
the Micro-Wand is not required to program and operate
the washer. The operation of the Micro-Wand and the
advanced features available are covered separately in
the Micro-Wand IIIE

™

instruction manual.

Smart Card Reader Communications
(Card Models Only)

The control will accept communication with a Card
Reader in order to perform vending transactions when
a card is inserted to pay for cycles. The card reader can
also allow the owner to program and collect audit
information.

For detailed information on Smart Card Reader
Communications, refer to the Smart Card Setup
Module in the NetMaster Smart Card Suite software
package.

Network Communications

The control will also accept communication with a
Network Interface Board which allows the control to
be linked to a personal computer. This network link
allows an owner to program, collect data and run
diagnostics on any machine.

For detailed information on Network Communications,
refer to the Network instruction manual.
