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

Installation

Section 4: Installation

To assemble the OM11 into the EPI2 actuator, proceed as follows:

• Ensure that all the parts received with the OM11 are available, as described in

Section 12, Optional Kits.

• Using Section 12, Optional Kits, select only mechanical parts (screws and spacers)

depending on actuator models.

• Gather the right tools for the assembly and for setting the actuator controls.

• With an Allen wrench of 5 mm, unscrew the cover screws, see Figure 5.

Figure 5

• Remove the actuator cover, see Figure 6.

Figure 6

Follow one of the following assembling procedures depending on actuator model.
