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
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:
May 2022
• 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.

Section 1: Optional Module 3: Local Interface Module
May 2022
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.

NOTES:
It is possible to invert LEDs color, so:
— red color for OPEN position and maneuver;
— green color for CLOSE position and maneuver.
To do this, see conguration section into Installation, Operation and Maintenance manual document.
It is also possible to invert LEDs color by means of Bluetooth optional connection (if present).

Section 4: To Locally Operate the Actuator
Once you have made sure that the actuator basic conguration is as requested by your
application, bring the 2-position selector to LOCAL and control the actuator by OPEN and
CLOSE pushbuttons.
The actuator can be driven to the desired position by pressing and holding the OPEN or
CLOSE pushbutton. When the pushbutton is released, the motor is de-energized and
stops. Once you have reached the fully open or fully closed positions, the actuator will
stop automatically.
