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
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 retrotting 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:
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 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.

WARNING
!
SCE300 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. 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, conguration, commissioning, maintenance and repair
works are carried out by qualied personnel and checked by responsible specialists.
