Optional Module 3: Local Interface Module
Section 1: Optional Module 3: Local Interface Module
Section 1: Optional Module 3: Local
Interface Module
1.1 Local Interface Functionality
The OM3 Local Interface module is supplied as an option on Keystone EPI2 actuators and
ts all models. It is possible to receive the actuator already equipped with the OM3 if
ordered together with the basic version. Alternatively, only for the water proof version, it is
possible to order the OM3 as a separate kit to be installed afterwards on the basic actuator.
The subsequent retrotting of the OM3 on existing EPI2 is not allowed in the explosion-
proof version. The OM3 is an optional module allowing local control with the following
additional functionalities:
• Selection of Local/Remote actuator control through the selector (lockable in
both positions).
• Open/Close command through the non intrusive pushbuttons.
• Actuator position indication by means of 2 LEDs.
NOTE:
For decommissioning instructions, please refer to the relevant section in
Installation, Operation and Maintenance Manual for Keystone EPI2 electric actuator.
!WARNING
EPI2 actuator must be electrically isolated before any disassembling and reassembling
operations. Before any disassembling or reassembling operations, please follow in detail the
relevant paragraph of the basic installation and operating manual (latest revision available).
!WARNING
The electronic parts of the EPI2 actuators and all optional modules can be damaged
by a discharge of static electricity. Before you start, touch a grounded metal surface to
discharge any static electricity.
NOTE:
The present IOM has to be considered integral part of the IOM for the basic
Installation, Operation and Maintenance Manual for Keystone EPI2 electric actuator.

Section 1: Optional Module 3: Local Interface Module
!WARNING
EPI2 actuators can be operated through a Bluetooth™ PDA or PC with the
following conguration:
• The commands are enabled by Bluetooth, only when the BT control is active. When
operating with Bluetooth™, the controls via PDA or PC have priority on any other
remote commands and allow full actuator operability from a distance also when
the valve is not visible. Special attention must be paid under this condition to avoid
any damages or injuries to people working close to the valve. Keystone will not
accept any responsibility for damages or injuries caused by an improper use of your
Bluetooth™ PDA or PC.
!WARNING
It is assumed that the installation, conguration, commissioning, maintenance and repair
works are carried out by qualied personnel and checked by responsible specialists.
!WARNING
Repair work, other than operations outlined in this manual, is strictly reserved to qualied
Emerson personnel or to personnel authorized by the company itself.
1.2 Manufacturer
Manufacturer with respect to Machinery Directive 2006/42/EC: Bif Italia as specied on
the actuator label.

Assembling Procedure
Section 2: Assembling Procedure
Section 2: Assembling Procedure
To assemble the OM3 Local Interface module onto the EPI2 actuator, proceed as follows:
• Ensure that all the parts received with the OM3 are available, see Figure 1:
Figure 1 OM3 kit for EPI2 actuator
Pos. Q.ty Description
1 1 Local Interface module
2 4 Screws for connecting connector
Table 1.
• Gather the right tools for the assembly: a 5 mm Allen key and a screwdriver as
shown in Figure 2.

4Assembling Procedure
Section 2: Assembling Procedure
• With the Allen key loosen the 4 cover screws and remove the terminal board
enclosure cover, see Figures 3. You will see the terminal board inside the actuator.
Remove the ground cable from the cover in the enclosure. The position of the
connections is shown on the yellow label that you will nd inside the cover just
removed, see Figure 4.

Assembling Procedure
Section 2: Assembling Procedure
• Connect the Local Interface module to the ground stud by screwing the
‘ground kit’ (screw + toothed washer).
Figure 5 Grounding the Local Interface
• Take the 4 screws for connecting the Local Interface black connector to the
terminal board, in pos. 28-29-30-31 (see Figure 6 and wiring diagram) and
connect it with the screwdriver shown in Figure 7.

6Assembling Procedure
Section 2: Assembling Procedure
• Now the Local Interface is connected to the actuator, see Figure 8.
• Take the 4 screws removed from terminal board cover and use them to x the Local
Interface to the actuator, using the 5 mm Allen key, see Figure 9.

Figure 9 Fixing the local interface onto the EPI2 actuator
NOTE:
Please note that the design of the Local Interface black connector has been engineered to
allow the installation in one way only. Due to the special design, it is not possible to reverse
the connection of the 4 cables to the terminal board and it is not possible to make a wrong
connection of the connector.
• The installation of the OM3 Local Interface module onto the EPI2 actuator is
now complete.
