1. Overview
Operators of the EZS128 system must read and understand this document before
attempting to operate the system or machinery controlled by the system. Failure to
read and understand this document may result in damage to machinery, personal
injury or loss of life.
This manual describes the basic operation of the EZSentinel 128 (EZS128). EZS128 is a combination
HMI / Controller that provides comprehensive hazard monitoring for primary facilities. It supports up
to 128 field sensors for bearing temperature, belt tracking, belt speed vibration, and plugged chute.
The HMI consists of a 6” (15 cm) touch screen Graphical User Interface (GUI). All operations are
undertaken from the user interface. Users of the EZS128 shall read this manual before operating the
system.
EZS128 documentation comprises:
• EZSentinel 128 Installation and Configuration Manual (manual number 11240)
• EZSentinel 128 User’s Manual (manual number 11242)
• Installing HazMon in a Box (manual number 11258)
Alarms
•Display, Alarms, and Control. The system provides display, alarming, and control for conveyors,
bucket elevators, drag conveyors, tripper conveyors and other machinery in a grain processing/
storage facility or fertilizer plant. The system consists of a field sensing network that collects
temperatures of bearings and belt tracking rub points, belt speeds, vibration velocity and simple
switches. Sensors are typically installed on all bearings and belt rub locations. A speed pickup is
installed on the conveyor tail pulley.
•Temperature and Under Speed Alarms. Alarms are set to indicate over temperature and under
speed conditions. Two levels of alarms can be setup, one to warn the operator and a second to
stop the machine. A method is provided to test the alarm set points from the touch screen
interface.
•Alarm Logs. Alarms and other system events are logged to an alarm event log on the controller’s
microSD (Secure Digital) card. Logs are maintained in separate files for each day. In addition, a
trend log of all sensor values can be recorded on the memory card.
•Security System. A comprehensive security system is provided. The security system restricts access
to the setup and configuration portions of the controller. This system logs access to critical system
interaction such as alarm silence, alarm test, and alarm bypass.
•Alarm Bypass. A temporary bypass of faulted sensor alarms is possible which stops alarm horns, or
the machine. The sensor alarm annunciators will still indicate and record the alarm in the event
log.

2.2. General Safety Information
Read and understand all safety instructions, safety decals, and manuals and follow them when operating or
maintaining the equipment.
• Owners must give instructions and review the information initially and annually with
all personnel before allowing them in the work area. Untrained users/operators
expose themselves and bystanders to possible serious injury or death.
• Use for intended purposes only.
• Modification of the ezsentinel 128 in any way without written permission from the manufacturer is not
covered by the warranty.

organization for information.
• Follow applicable local codes and regulations.
2.3. HAZMON Safety
Follow safety procedures while starting and stopping the Hazard Monitoring system including
personnel notification, site permits, etc.
• Do not operate plant or equipment with compromised system.
• To prevent exposure to potential ignition source, do not open the IS Bus Converter cover in dust explosive
atmosphere while energized. Field Interconnect Boxes may be opened for troubleshooting purposes with
power applied when dust is settled – see next warning:

• Remove dust and condensation away from enclosure seals before opening to prevent contamination.
• Do not bypass alarm controls when operating the system. Follow safety protocols to verify there are no
hazards such as heat sources, blockages, lack of guarding, etc.
• Validate sensor positions after regular system maintenance, and immediately after installing replacement
parts before operating machines. Always test interlocks during commissioning and on a periodic basis
recording their functionality.
• Inspect sensors, associated wiring and enclosures for damage and proper installation on regular interval.
2.4. Drives and Lockout/Tagout Safety
Inspect the power source(s) before using and know how to shut down in an emergency.
Whenever you service or adjust your equipment, make sure you shut down your power
source and follow lockout and tagout procedures to prevent inadvertent start-up and
hazardous energy release. Know the procedure(s) that applies to your equipment from the
following power sources.
For example:
WARNING
• De-energize, block, and dissipate all sources of hazardous energy.
• Lock out and tag out all forms of hazardous energy.
• Ensure that only 1 key exists for each assigned lock, and that you are the only one that holds that key.
• After verifying all energy sources are de-energized, service or maintenance may be performed.
• Ensure that all personnel are clear before turning on power to equipment.
For more information on occupational safety practices, contact your local health and safety organization.
