Operation (HMI/PC)
The purpose of this section is to describe the steps
that are necessary to interrogate the M-3311A utilizing
either the optional M-3931 HMI or a PC running
S-3300 IPScom
®
Communications software through
COM1 the front RS-232 serial port. These instructions
assume that the following conditions exist:
• The unit is energized from an appropriate
power supply.
See Chapter 5,
Installation
, Section 5.3,
External Connections, for power supply
connection details.
• For PC communications, IPScom is
installed on the host PC.
See Chapter 5,
Installation
, Section
5.6, IPScom Communications Software
Installation, if IPScom is not installed.
• For PC communication, initial PC
communication has been established with
the unit.
If this is the first attempt to establish
communications with the unit, then see
Chapter 5,
Installation
, Section 5.7,
Activating Initial Local Communications.
HMI Operation Overview
Whenever power is applied to the unit the Power On
Self Test sequence is initiated (Figure 2-2).
Default Message Screens
When the M-3311A is energized and unattended,
the user logo lines are blank.
If a protective function has operated and has not
been reset, the HMI will display the target(s) with
the time and date of the operation and automatically
cycle through target screen for each applicable
target. This sequence is illustrated in Figure 2-2.
In either case, pressing the
ENTER
pushbutton will
begin local mode operation by displaying the access
code entry screen, or if access codes are disabled,
the first level menu will be displayed (Figure 2-3).
HMI Security
To prevent unauthorized access to the relay functions,
the relay includes the provision for assigning access
codes. If access codes have been assigned, the
access code entry screen will be displayed after
ENTER
is pressed from the default message screen.
The relay is shipped with the access code feature
disabled.
The relay includes three levels of access codes.
Depending on the access code each level holds, users
have varying levels of access to the relay functions.
