I. Introduction
Congratulations! You have purchased the ETI MNPR™ Microprocessor Network
Protector Relay and Programmer. The MNPR™ is the most advanced
microprocessor based relay on the market. It combines extensive programmability
with advanced communications capability. In order to make proper use of your new
MNPR™ you need to become familiar with the MNPR™ Programmer. This manual
contains detailed instructions regarding operation of the Programmer, as well as
some tips on effective MNPR™ programming.
The MNPR™ Programmer can display and modify the status and settings of the
MNPR™. The Programmer also has the ability to store settings for sensitive
(standard) mode, insensitive mode, time delay mode and watt-var mode operation.
This feature allows field personnel to quickly program the MNPR™ to predetermined
settings.
The MNPR™ Programmer is a simple, user friendly device. Its operation is similar
to that of a vending machine. Specifically, there are letters along the bottom and
numbers along the right side of the Programmer face. All of the features present on
the Programmer’s face have letter/number coordinates. In order to select a feature,
simply line up the feature with the letter below it and the number on its right. Press
the letter first and then the number. If you press a number first, the Programmer will
remind you to
“Press A, B, C or D first then 1, 2, 3 or 4 to select an option”
.
