The ElectroGuard Safety Isolation System is used in place of a
disconnect switch for Lockout and Tagout (LOTO). It uses power
contactors and Remote Lockout Stations to accomplish LOTO.
Isolating the electrical energy usually involves calling an electrician to
turn “Off ” the main disconnecting means. The electrician would
then perform LOTO of the disconnecting means operating handle.
This same procedure is required to perform cleaning, maintenance,
setup, lubrication or adjustment. Machines or processes with
multiple access points may require operator/maintenance
intervention several times a shift (perhaps as often as 60 times per
shift).
To perform these activities, the operator/maintenance person may
be required to place part of his or her body into an area not accessed
during normal operation. This may cause serious or fatal injury if
LOTO procedures are not followed.
The ElectroGuard Safety Isolation System allows the machine
operator to safely and quickly accomplish LOTO with dramatically
reduced downtime.
Provides Energy Isolation
• Power isolation accomplished by means of contactors rather than
disconnect switches.
• Uses redundant, independent and self-monitoring circuits to
detect a system fault.
• Prevents accumulation of faults in order to maintain the integrity
of the safety system.
• Tamper-resistant design.
Convenient Remote Lockout Station
• Allows remote isolation of the electrical power to the machine or
process—machine operator simply turns “Off ” a Remote
Lockout Station.
• A light on the Remote Lockout Station indicates that the three-
phase power source to the machine or process has been isolated.
No Light Means No Entry.
• If a fault occurs in the Safety Isolation System, the “System
Isolated” light on the Remote Lockout Stations will not
illuminate.
• Easy Lockout/Tagout.
Certified by TUV to meet requirements of Category 4
• Certified by TUV to meet Category 4, the most stringent safety
category defined within International Standard EN 954-1/ISO
13849-1.
• Subjected by TUV to rigorous third party testing and verification
of the Failure Mode & Effect Analysis (FMEA).

After using the normal stopping
method of the machine or process,
the machine operator turns a
Remote Lockout Station handle
from the “On” to “Off ” position.
The station signals the isolation
contactors (1IC and 2IC) to drop
out and isolate the supply voltage
from the loads (see Control
Circuit).
When system residual voltage
decays to pre-determined levels,
the grounding contactor (GC) is
energized, connecting the load to
ground (see Power Circuit). The
grounding contactor (GC) is
electrically and mechanically
interlocked with the isolation
contactors (1IC and 2IC).
The “System Isolated” Light will
now illuminate on the Remote
Lockout Station to indicate the
system is isolated. The machine
operator then Locks-Out and
Tags-Out the station in the “Off ”
position.

Optional Features
Pneumatic Isolation Module (Must be ordered with Safety Isolation System):
The Safety Isolation System is available with an optional means of isolating the pneumatic energy source
for the machine or process. If the machine operator/maintenance personnel initiates isolation of the
electrical energy by operating one of the Remote Lockout Stations, a safety valve is simultaneously
actuated to bleed pressure from the air line between the valve and the machine. When the air pressure has
fallen to a predetermined level, the unit will allow the light on the Remote Lockout Station to illuminate,
if electrical isolation has also been achieved.
To order the Pneumatic Isolation option:
Step 1:
Add the following Catalogue String to the Safety Isolation System Catalogue Number:
To indicate that the Safety Isolation
System should be supplied as “Pneumatic
Ready.”

e.g.
2031-A0085JB-1PN

Remote Lockout Stations, or
total wire lengths longer than
those permitted with the
Remote Lockout Stations.
Expansion Modules are
available in 4 or 10 port
configurations. Each Expansion
Module is wired to a port on the Control Module, and takes the
connection port that would normally accommodate a Remote
Lockout Station (see page 12-18 to determine if an Expansion
Module is required due to wire length considerations).
The 23A through 85A systems will accommodate connection of a
maximum of 4 Expansion Modules, and the 110A through 1200A
systems will accommodate connection of a maximum of 6
Expansion Modules.
Certain ampere size Safety Isolation System Power Panels can
accommodate either 1 or 2 Expansion Modules installed internally.
In all other instances the Expansion Module(s) must be located
external to the Safety Isolation System in a suitably rated enclosure.
