Chapter 28: ANNUNCIATOR mODULe
INTRODUCTION
The SCADA 3000 Annunciator Module is an optional component for use with the SCADA
3000 system. The module provides 8 programmable LED indicators to display the status of
assigned I/O points. The LEDs are bi-color (red/amber), which means that each LED is
always on, thereby preventing a false reading due to a burned-out LED. Red indicates an active
or ON condition and Amber indicates an inactive or OFF condition. The Annunciator LEDs
appear as two-state (ON/OFF) outputs in the SCADA 3000 software. The Annunciator module
is housed in a
1

DIN enclosure for convenient panel mounting.
INSTALLATION
This chapter provides information necessary to install the Annunciator Module. Correctly
installing the unit will ensure proper functioning and maximum service life. Please read the
entire chapter before attempting installation.
OPeRATING eNVIRONmeNT
The Annunciator Module should be mounted and operated in a clean, dry and safe environ-
ment. Do not mount the unit where it will be subject to shock and vibration. Do not mount
the unit where it will be subject to dirt, dust or moisture. Ideally the unit would be mounted
in a steel or a fiberglass NEMA-4 enclosure. Do not mount the unit or the expansion modules
close to motor starters, contactors or relays that switch inductive loads. These devices gener-
ate large electromagnetic fields that can cause the Annunciator Module to malfunction. Where
this is unavoidable, mount the module(s) and main unit in a separate, grounded, steel enclosure.
This will shield them from harmful electrical interference.
The temperature range the Annunciator Module can operate in is 32°F to 158°F (0°C to
70°C). If you require Annunciator Module to operate in a below freezing environment, you
must take safe and practical measures to keep the module’s temperature above 32°F or it will
not operate reliably.
CAUTION
: The Annunciator Module is a sensitive electronic device.
Personnel and work area should be grounded before handling this device. Do
not install a SCADA 3000 system near any strong electrostatic, electromagnetic,
magnetic or radioactive fields. Do not expose it to fumes or corrosive vapors.
mOUNTING THe ANNUNCIATOR mODULe
The Annunciator Module is packaged in a standard
1
⁄
8
DIN enclosure. This style of enclosure is
designed to be flush-mounted in a panel or door. The module includes all the hardware neces-
sary for mounting; however, a small Allen wrench will be required to secure the enclosure to
the panel. To mount the module, cut a hole in the panel according to the dimensions shown in
Figure 1 below.
