Section 1: Introduction
Introduction
NOTE:
Before installation, these instructions must be fully read and understood.
Section 1: Introduction
The OM11 DeviceNet interface is an electronic module that allows you to connect the
Keystone EPI2 electrical actuator to a DeviceNet network. The module has its own
microprocessor and acts as a pure bus interface without affecting the actuator control
integrity. It is installed inside the actuator housing and takes the electrical power from the
actuator power supply module. The DeviceNet network is fully isolated from the
actuator electronics.
For details about EPI2 actuator, please refer to Installation, Operation and Maintenance
Manual for Keystone EPI2, Electric Actuator.
!WARNING
EPI2 actuators must be electrically isolated before any disassembling or reassembling
operations. Before any disassembling or reassembling operations, please follow in detail
the relevant section of the basic installation and operating manual (latest revision available).
!WARNING
The electronic parts of the EPI2 actuators and all option modules can be damaged by
a discharge of static electricity. Before you start, touch a grounded metal surface to
discharge any static electricity.

Section 3: Distinguish Old/New Models
It is important to distinguish between EPI2 old models and the new ones. To install the
board on base actuator, in fact, it is necessary to choose the correct mechanical parts from
the kit.
Furthermore, the meaning of some data exchanged on the DeviceNet interface depends
on model (old or new); differences will be explained in the following sections.
Figures 1 and 2 allow to distinguish old version of EPI2 from the new version (on the labels,
the digits of Product Number are boxed); furthermore, the logic boards with heatsink

6.3 Bus/Hardwired Mode Selection
The DeviceNet interface manages the bus/hardwired mode selection by means of the
input terminal indicated with HW MODE. The physical input accepts from 24 V - 125 V DC
or AC, polarity insensitive. When the input is left unconnected or no voltage is applied,
the actuator is under bus control from which is possible to send commands and read
status. When an appropriate voltage is applied to the HW MODE input, the actuator turns
under Hardwired control. In this condition, the bus can only read actuator status while the
actuator follows the hardwired open and close controls connected to the terminal board.
For further details, please refer to Installation, Operation and Maintenance Manual for
Keystone EPI2, Electric Actuator.

DeviceNetisalow-levelnetworkthatprovidesconnectionbetweenindustrialelddevices
(sensors and actuators) and higher-level devices (controllers). DeviceNet uses CAN
(Controller Area Network) for its datalink layer, and CIP (Common Industrial Protocol)
for the upper layers of the network. The major physical and media characteristics of the
DeviceNet are:
• Trunk-line/drop-line topology of the network
• Support for up to 64 devices in a network (i.e., 1 master and 63 EPI2 actuators)
• Node removal without altering the network behavior
• Support of both network-powered and self-powered devices on the
same network
• Wiring error protection
• Selectable data rate of 125 k baud, 250 k baud and 500 k baud

• Adjustablepowercongurationtomeetindividualapplicationneeds
• High current capability (up to 8 A at 24 V DC)
• Operation with off-the-shelf power supplies
• Available power taps that allow the connection of several power suppliers
• Built-in overload protection
