Bettis OM3 – SCE300
Local Interface Module
Instruction Manual

**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 fits 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 waterproof version, it is possible to order the OM3 as a separate kit to be installed afterward on the basic actuator. The subsequent retrofitting of the OM3 on the 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 nonintrusive pushbuttons.
• Actuator position indication by means of 2 LEDs.

NOTE:
For decommissioning instructions, please refer to the relevant section in the 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 configuration:

• 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 over 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 improper use of your Bluetooth™ PDA or PC.

WARNING
It is assumed that the installation, configuration, commissioning, maintenance, and repair works are carried out by qualified personnel and checked by responsible specialists.
WARNING
Repair work, other than operations outlined in this manual, is strictly reserved for qualified Emerson personnel or personnel authorized by the company itself.

1.2 Manufacturer
Manufacturer with respect to Machinery Directive 2006/42/EC: Emerson as specified on the actuator label.

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

Table 1.

• Gather the right tools for the assembly: a 5 mm Allen key and a screwdriver as shown in Figure 2.

Figure 2: Tools for installing OM3 kit

• With the Allen key loosen the 4 cover screws and remove the terminal board enclosure cover, see Figure 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 find inside the cover just removed, see Figure 4.

Figure 3: Removing terminal board enclosure cover

Figure 4: Electrical connections

WARNING
Pay attention not to damage the joint surfaces of the cover/enclosures.

• 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.

Figure 6: Position of the Local Interface connector on the terminal board

Figure 7: Connecting the Local Interface connector

• Now the Local Interface is connected to the actuator, see Figure 8.
• Take the 4 screws removed from the terminal board cover and use them to fix the Local Interface to the actuator, using the 5 mm Allen key, see Figure 9.

Figure 8: OM3 kit connected to the SCE300 terminal board

Figure 9: Fixing the local interface onto the SCE300 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 SCE300 actuator is now complete.

3.1 Local Operator Interface
The following functions are available through the SCE300 Local Interface module (OM3):

• Selection of Local/Remote actuator control through the selector (lockable in both positions).
• Local actuator control: OPEN/CLOSE command through the non-intrusive pushbuttons.
• Actuator position indication by means of 2 LEDs (green and red).

3.2 Description of the Local Interface
3.2.1 2-Position Selector

• Local: to enable the local control only.
• Remote: to enable the remote control and local control via Bluetooth with PC and PDA.

3.2.2 LEDs Indicating the Position of the SCE300 Actuator
The two LEDs indicate the actuator status according to the following logic:

Table 3.

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 the configuration section in the Installation, Operation, and Maintenance manual document.
It is also possible to invert LED color by means of a Bluetooth optional connection (if present).

3.2.3 OPEN/CLOSE Pushbuttons
The two OPEN and CLOSE pushbuttons are push-to-run types 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 configuration 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.

WARNING
Do not operate the Electric Actuator electrically when the Local Control Panel is removed from the terminal board enclosure. Operating the unit with electrical enclosures not protected by their covers could cause personal injury.

8.4 Installation in Ambient with Explosive Dust
NOTE:
The installation and maintenance must be carried out in accordance with IEC 61241-14. Special attention must do to the following points:

• The cable glands must have a protection degree at a minimum of IP 66/68 (IEC 60529).
• Periodically verify the quantity of dust deposited on the enclosure and clean it in case the quantity becomes more than 5 mm.

Section 9: Special Maintenance

WARNING
The maintenance and any repair works must be carried out by personnel specifically qualified and fully trained for works in hazardous areas.

9.1 Periodic Inspections
A. Frequency of inspection may depend form the installation and working conditions; in general, at least one inspection every two years is recommended.
B. Inspect the Electrical Actuator with particular attention to electrical enclosures conditions.
WARNING
Any damage or breaking found on the enclosures, lack of screws fixing the covers, or loosening screws must require immediate maintenance action.
C. Keep the external surface clean: if the Electrical Actuators are installed in a dusty environment the specification stated in IEC 61241-14 be followed ensuring in particular that the dust layer does not exceed 5 mm.
D. Check the condition of cable connection and mounting bolts: any loose connection must be amended.

9.2 Repairs of Intrinsically-Safe Parts
WARNING
In case the maintenance should require the replacement of any component which forms part of the Local Control Panel only an original spare provided by Emerson MUST be used. Direct repair or reconstruction of the above components is not permitted without Emerson’s permission. Not performing this procedure will invalidate the product safety and contractual guarantee.
Original spare parts must be required to Emerson: to ensure that the right spare is provided, the serial number printed on the Electric Actuator label MUST be specified when spares are ordered.
