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 Bettis SCE300 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 retrotting of the OM3 on existing SCE300 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 Bettis SCE300 electric actuator.
!WARNING
SCE300 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 SCE300 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 Bettis SCE300 electric actuator.

Section 1: Optional Module 3: Local Interface Module
!WARNING
SCE300 actuators can be operated through a Bluetooth™ PDA or PC with the
following conguration:
• 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. Bettis 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, conguration, commissioning, maintenance and repair
works are carried out by qualied personnel and checked by responsible specialists.
!WARNING
Repair work, other than operations outlined in this manual, is strictly reserved to qualied
Emerson personnel or to personnel authorized by the company itself.

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 SCE300 actuator is
now complete.

Green LED Red LED Indication
ON OFF Actuator stopped in completely OPEN position
OFF ON Actuator stopped in completely CLOSED position
OFF Flashing Actuator running in CLOSING direction
Flashing OFF Actuator running in OPENING direction
ON ON Actuator stopped in INTERMEDIATE position
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 conguration section into Installation, Operation and Maintenance manual document.
It is also possible to invert LEDs color by means of Bluetooth optional connection (if present).
3.2.3 OPEN/CLOSE Pushbuttons
The two OPEN and CLOSE pushbuttons are push-to-run type only. Once the pushbuttons
are released, the actuator stops.

Section 4: To Locally Operate the Actuator
Once you have made sure that the actuator basic conguration 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.

Section 8: Installation
8.1 Working Conditions
The Electric Actuators SCE300 with OM3 are suitable for the following ambient
temperatures from -40 °C to +65 °C (from -40 °F to +149 °F).
NOTE:
Check the ‘temperature ambient range’ embossed on the nameplate, for the correct
utilization with respect to the ambient temperature conditions.
8.2 Electrical Connections
Before applying electrical power to the actuator check that the electrical parameters
(supply voltage and current) shown on the nameplate, are correct for this installation.
NOTE:
The installation and maintenance must be carried out in accordance to the applicable
rules regarding the electrical installations in hazardous area (other than mines) classied as
Zone 1 (gas): IEC 60079-10; IEC 60079-14; IEC 60079-17 and/or other national standards.
8.3 Instructions for the Intrinsically-Safe Enclosures
NOTE:
