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.

1.2 Manufacturer

Manufacturer with respect to Machinery Directive 2006/42/EC: Emerson as specied on

the actuator label.

Assembling Procedure

Section 2: Assembling Procedure

To assemble the OM3 Local Interface module onto the SCE300 actuator, proceed as follows:

• Ensure that all the parts received with the OM3 are available, see Figure 1:

Figure 1 OM3 kit for SCE300 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.

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.
