Specifications
Approvals
Standards
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 threephase 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).

Overview
Principle of Operation
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).

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.”
-1PN
e.g. 2031-A0085JB-1PN to indicate an 85A Safety Isolation System that is to be “Pneumatic Ready.”

Optional Features (continued)
Status Communication to a remote PLC (Should be ordered with Safety Isolation System)
This option provides Remote I/O via “Flex” modules. Communication can be via:
• The DeviceNet communication platform, or
• The Remote I/O communication platform.
Note: The status communication option allows a remote PLC to receive status signals
from the ElectroGuard Safety Isolation System. The ElectroGuard does not accept input
signals through these communication platforms.
Status communication capabilities:
•
•
•
•
Overall system status,
Status of each Remote Lockout Station,
Status of the Pneumatic Isolation Module (if used),
Status of other optional Safety Input devices.
Note: Each communication module provides sixteen (16) data points. In determining which Catalogue Number String to specify from the table below,
please keep the following in mind:
•

The wire length from RLS # 2 to the Control Module will be 200ft.
The wire length from RLS # 3 to the Control Module will be 100ft.
The wire length from RLS # 4 to the Control Module will be 300ft.
The wire length from RLS # 5 to the Control Module will be 500ft.
The wire length from RLS # 6 to the Control Module will be 1000ft.
The wire length from RLS # 7 to the Control Module will be 850ft.
The wire length from RLS # 8 to the Control Module will be 750ft.
14AWG wire will be used to connect the RLS to the Control Module
(see illustration below).
Wire Length Considerations
ATTENTION: It is important not to
exceed the maximum wire length values
shown in this section. If the maximum values
are exceeded, this may result in an unreliable
signal to the Safety Isolation System.
Consider using an Expansion Module if wire
lengths greater than those shown for the
Remote Lockout Stations are needed.

1. Determine the distance in feet or meters from each Remote
Lockout Station to the Control Module (located inside the Safety
Isolation System Power Panel).
2. Sum the distances for all of the Remote Lockout Stations.
3. Double this value.
4. Compare this doubled value with the maximum values for total
wire length shown in the table below:

Analysis: The Control Module furnished with the 630A Safety
Isolation System is capable of supporting a maximum of six (6) RLS.
Since this installation will require eight (8) RLS, an optional 4 port
Expansion Module will also be used. The Expansion Module will be
wired to the Control Module and will take the place of one of the
original six RLS. We will, therefore, plan to wire five (5) of the RLS
directly to the Control Module and three (3) of the RLS to the
Expansion Module. Since the Expansion Module allows greater wire
lengths than the Control Module, we will plan to wire the RLS to be
installed furthest away from the Power Panel to the Expansion
Module.
For RLS # 1: wire length = 50ft x 2 = 100ft
For RLS # 2: wire length = 200ft x 2 = 400ft
For RLS # 3: wire length = 100ft x 2 = 200ft
For RLS # 4: wire length = 300ft x 2 = 600ft
For RLS # 5: wire length = 500ft x 2 = 1000ft

Wire Length Considerations/Ordering Instructions
The total wire length for the 5 RLS to be wired to the Control
Module will be: 100ft + 400ft + 200ft + 600ft + 1,000ft = 2,300ft
Per the table entitled Total Wire Length for Remote Lockout Stations on
page 12-18, the maximum allowable wire length for 14AWG wire is
4,600ft for the RLS to be wired to the Control Module. This portion
of the installation will be within the maximum wire length permitted.
Next, we need to check the wire length calculation for the RLS to be
wired to the Expansion Module.
For RLS # 6: wire length = 1000ft x 2 = 200ft
For RLS # 7: wire length = 850ft x 2 = 1700ft
For RLS # 8: wire length = 750ft x 2 = 1500ft
The total wire length for the 3 RLS to be wired to the Expansion
Module will be: 2000ft + 1700ft + 1500ft = 5,200ft
Per the table entitled Total Wire Length for Expansion Modules on page
12-18, the maximum allowable wire length for 14AWG wire is
40,000ft for the RLS to be wired to the Expansion Module. This
portion of the installation will also be within the maximum wire
length permitted.
Ordering Instructions
1. Determine the Catalogue Number of the Safety Isolation System
based on the rating of the load(s) to which it will be connected as
follows:
If the Safety Isolation System is connected to a single motor load,
the horsepower or kilowatt rating of the system should be
determined as follows:
a. Select the Safety Isolation System that meets or exceeds the
horsepower or kilowatt rating of the load at the required
voltage and frequency.
If the Safety Isolation System is connected to two or more
motors or one or more motors in combination with other loads,
the horsepower or kilowatt rating of the system should be
determined as follows:
a. Identify the types of loads (i.e. motor, resistive) and the values
of the currents of each of the loads (i.e. steady-state current
for resistive loads, full-load and locked-rotor currents for
motor loads) to be connected to the Safety Isolation System.
2.
3.
4.
5.
b. Sum the full-load currents of all the motor loads to be
connected to the Safety Isolation System. To this value add
the current values of all resistive loads to be connected to
the Safety Isolation System. This value is the “combined
load full-load current.”
c. Find the horsepower or kilowatt rating of a single motor with
a full-load current value greater than or equal to the
“combined load full-load current” value determined in Step
“b”.
d. Select the Safety Isolation System that meets or exceeds this
horsepower or kilowatt rating at the required voltage and
frequency.
e. Sum the locked-rotor currents of all the motor loads to be
connected to the Safety Isolation System. To this value add
the current values of all resistive loads to be connected to
the Safety Isolation System. This value is the “combined
load locked-rotor current”.
f. Find the horsepower or kilowatt rating of a single motor with
a locked-rotor current value greater than or equal to the
“combined load locked-rotor current” value determined in
Step “e”.
g. Select the Safety Isolation System that meets or exceeds this
horsepower or kilowatt rating at the required voltage and
frequency.
h. Compare the ratings of the Safety Isolation Systems selected
in Steps “d” and “g”. Select the larger of the two systems for
your application.
Determine how many Remote Lockout Stations are required for
the application.
Determine how many Expansion Modules (if any) are required
for the application.
Pick suitable enclosure type(s) for the Safety Isolation System
Power Panel, Remote Lockout Stations and enclosed modules
(e.g., Expansion Modules, Pneumatic Isolation Module).
Determine what, if any, factory installed options are required for
the application (e.g. Pneumatic Isolation, Status Communication
to remote PLC, metering).
