DESCRIPTION
General Information
• Network Media - DeviceNet
• Protocol - DeviceNet Rel 2.0
• Type - Group 2 Only Slave Device using Predefined
Master Slave Connection Set
• Bandwidth - 125, 250, 500 Kbaud
All E50 Limit Switches consist of two modular, interchange-
able plug-in components: operating head and a solid state
switch body. Operating heads (side rotary, top and side
push, and wobble stick) are mounted on top of the switch
body in any of four positions. All assembled limit switches are
rated NEMA 3, 3S, 4, 4X, 6, 6P and 13. Obtain renewal parts by
ordering the catalog number labeled on each of the two limit
switch components.
NEMA ICS 2-225 describes preferred installation recommenda-
tions which ensure greatest reliability and longest life expect-
ancy for Industrial Limit Switches.
INSTALLATION
WARNING
DO NOT INSTALL OR PERFORM MAINTENANCE ON THIS
DEVICE WHILE THE CONTROLLER IS ENERGIZED. DEATH OR
SEVERE PERSONAL INJURY CAN RESULT FROM CONTACT
WITH ENERGIZED EQUIPMENT. VERIFY THAT NO VOLTAGE IS
PRESENT BEFORE PROCEEDING WITH INSTALLATION OR
MAINTENANCE. Only qualified persons, as defined in the
National Electric Code, who are familiar with the installation,
maintenance and operation of this device and the equipment
onto which is to be installed, as well as applicable local, state
and national regulations and industry standards and
accepted practices regarding safety of personnel and the
equipment safety should be permitted to install, maintain or
operate this device. These instructions are provided only as
a general guide to such qualified persons and are not all-
inclusive. They do not cover every application or circum-
stances which may arise in the installation, maintenance or
operation of this equipment. Users are advised to comply
with all local, state and national regulations and industry
standards and accepted practices regarding safety of
personnel and the equipment safety.

OPERATING HEAD POSITIONING
Heads can be mounted on the switch body in any of four
directions, 90° apart. Torque screws according to require-
ments on page 1.
OPERATING HEADS — SIDE ROTARY
The operating mode (CW, CCW or CW and CCW) of these
spring return operating heads is easily changed without
tools as shown in the illustration. Remove the head from
switch body. Pull out the plunger and turn until its position
matches that shown on the diagram for the desired opera-
tion mode. Levers are adjustable to any angle (360°). The
operating shaft screwdriver slot can be used to maintain
shaft position during lever installation.

OPERATING HEADS — WOBBLE STICK
These spring return, top operated heads use different rod-
type operators to detect motion in any direction perpendicu-
lar to the operator. The operator screws onto the threaded
head stub.
TORQUE REQUIREMENTS FOR LIMIT SWITCH ASSEMBLY
Tighten the operating head screws to a torque value within the
following ranges to ensure and maintain the Enclosure Type
Ratings for the assembled limit switch.
Operating Head Screws — Tighten to ensure contact of head
to switch body: 14 - 18 lb. in.
OPERATING HEADS — PUSH OPERATED
These spring return top push or side push operating heads
are available in pushbutton and roller styles.
The push roller style can be converted from vertical to
horizontal operation or vice versa. Pull roller out of the head
until it can be rotated 90° to the desired orientation. When
released, it will snap into the set position.
The Maintained Contact head has the reset pushbutton
located opposite of the actuator pushbutton.

REPEAT ACCURACY
The type of operating head used on an assembled limit
switch determines repeat accuracy for the switch assembly.
Assembled limit switches, without rollers used on operating
heads or levers, have a repeat accuracy as listed in Table 1
only.
Assembled limit switches with rollers used on operating
heads or levers have a repeat accuracy determined as
follows: add the repeat accuracy tolerance of Table 1 for the
type of operating head used to the concentricity tolerance of
Table 2 for the type of roller used on the lever or operator.
The combination of these two tolerances is the limit switch
repeat accuracy.

DEVICE CONFIGURATION
Before using the E50 limit switch, you must configure the
device’s baud rate and network address. The baud rate
defaults to 125 kbaud, and the address defaults to 63.
Additional parameters you may wish to configure include the
on, off, and one-shot delay, and the operate mode. After
connecting the device to the network, use NetView or
another configuration tool to configure device.
Network Address
After connecting the E50 to the network, use the Netview
configuration software (or other configuration software) to
configure the device. Unless pre-configured, a new device
will have a default address of 63 at a baud rate of 125 Kbaud
when connected to the network.
CAUTION
Since all new DeviceNet devices are factory set to address
63, it is usually not a good idea to leave an address set at
63. Two nodes at the same address will cause a network
fault!
Built into the Cutler-Hammer Netview configuration software
is a function to locate nodes by continually flashing the
Module/Network Status LED between green and red. Once the
Netview configuration software is communicating to the E50,
the address and all other user configurable parameters can then
be programmed. (See the Netview manual for specific informa-
tion on how to change attributes.) A list of configurable
attributes can be found on page 5 of this manual.
Off-line Configuration
An E50 switch may be configured off-line by connecting it
directly to the configuration tool (PC with software or a
hand-held type tool) and following the instructions for on-
line configuration. 24 VDC must still be supplied to the
switch in order to configure it off-line.
WIRING CONSIDERATIONS
ATTENTION
THE DEVICENET CABLE IS NEC (UL)TYPE CL2
RATED. THE CABLE IS NOT SUITABLE FOR USE IN
ENVIRONMENTS REQUIRING RESISTANCE TO
CERTAIN OILS AND CUTTING FLUIDS. PLEASE
CONSULT FACTORY FOR CABLING OPTIONS FOR
THESE APPLICATIONS.

Output takes into account the On Delay , Off Delay , One Shot Delay ,
and
Operate Mode . Switch state represents the physical location of
the limit switch.
Head Actuation Count increments each time the head is actuated.
When
Head Actuation Count reaches 80% or 100% of the Max Head
Actuation Count
, a fault is added to the diagnostic object. Maximum
head actuation count is based on Mean Time Between Failure (MTBF)
data and therefore statistically some units could potentially fail earlier
than that, as well as operate well past that number.
The
Diagnose Nonactuated Switch service causes the device to
perform a self diagnostic on its sensing circuitry. The test is only
valid if the limit switch is in the nonactuated position. Running this
test is the only way to clear the
Diagnostic bit.
Assembly Object Data - Class 4 (04HEX), Instance 1

Data 3 Get
Use Assembly Object Data to read diagnostic and output status. Data
bit 0 is output status, which is obtained from Attribute 1 of the
Presence Sensing Object. Data bit 1 is diagnostic status, which is
obtained from Attribute 4 of the Presence Sensing Object. The
remaining bits (2..7) are 0.
The I/O Poll and I/O Bit Strobe connections consume 0 bytes and
product 1 byte. The one produced byte is

SOFTWARE TIMING
The E50 is not capable of responding to all DeviceNet messages at all
baud rates if multiple messages are sent in rapid succession. For
best results, a master should wait for a response to a previous
request before sensing a subsequent request.
