5.1 Introduction
5.1.1 Setpoint Entry Methods
Prior to operating the PQMII, it is necessary to program setpoints to define system
characteristics and alarm settings by one of the following methods:
• Front panel, using the keys and display.
• Rear terminal RS485 port COM1 or COM2, or front RS232 port and a computer
running the EnerVista PQMII Setup Software included with the PQMII, or from a
SCADA system running user-defined software.
Either of the above methods can be used to enter the same information. However, a
computer makes information entry considerably easier. Moreover, a computer allows
setpoint files to be stored and downloaded for fast, error-free entry. The EnerVista PQMII
Setup Software included with the PQMII facilitates this process. With this software,
setpoints can be modified remotely and downloaded at a later time to the PQMII. Refer to
4.4: Using the EnerVista PQMII Setup Software for additional details.
Setpoint messages are organized into logical groups or pages for easy reference.
Messages may vary somewhat from those illustrated because of installed options, and
messages associated with disabled features will be hidden. This context sensitive
operation eliminates confusing detail. Before accurate monitoring can begin, the setpoints
on each page should be worked through, entering values either by local keypad or
computer.
The PQMII leaves the factory with setpoints programmed to default values. These values
are shown in all setpoint message illustrations. Many of these factory default values can be
left unchanged. At a minimum, however, setpoints that are shown shaded in 5.3.1: Current
and Voltage Configuration must be entered for the system to function correctly. As a
safeguard, the PQMII will alarm and lock-out until values have been entered for these
setpoints. The
CRITICAL SETPOINTS NOT STORED alarm message will be displayed until the
PQMII is programmed with these critical setpoints.
