1. Introduction 2. Product overview

1. IntroductionThis manual describes the installation and the basic operation of the motorized change-over switches (type OTM_). The instructive part is followed by a section on available accessories.

1.1 Use of symbols

Hazardous voltage: warns about a situation where a hazardous voltage may causephysical injury to a person or damage to equipment.

General warning: warns about a situation where something other than electricalequipment may cause physical injury to a person or damage to equipment.

Caution: provides important information or warns about a situation that mayhave a detrimental effect on equipment.

Information: provides important information about the equipment.

2. Product overviewMotorized change-over switches (type OTM_C) are suitable for remote control. You can operate the motorized change-over switches either electrically by using the motor operator or manually by using the handle. The operation, either electrical or manual, can be chosen by the selector switch “Motor/Manual” on the motor operator. Motorized change-over switches consist of the change-over switch and the motor operator.

3. Quick startThis is a quick guide only meant for those who need a reminder of how to operate the unit. For more detailed instructions, see chapter 6.

3.1 Controlling the motorized change-over switch electrically; remote controlTo control the motorized change-over switch electrically:

1. Remove the handle from the change-over switch panel. You can remove the handle in both positions (I, 0, II).2. Turn the Motor/Manual selector to the Motor (M) position to enable electrical control.

Figure 3.1 Controlling the motorized change-over switch electrically; remote control

3.1.1 Locking electrical controlTo disable electrical control, lock the locking latch with a padlock. After the locking latch has been locked, the motorized change-over switch cannot be controlled electrically. You can lock electrical control in both positions (I, 0, II).

3.2 Controlling the motorized change-over switch manually; local operationTo control the motorized change-over switch manually:

1. Turn the Motor/Manual selector to the Manual (Man.) position to enable manual operation and to prevent electrical operation.2. Attach the handle to the change-over switch panel. You can attach the handle in both positions (I, 0, II).

Figure 3.2 Locking electrical control

Figure 3.3 Operating the motorized change-over switch manually

To disable the manual (and at the same time also electrical) operation, lift up the locking clip to position 0 and attach the padlock to the handle.

Do not install the motorized change-over switches in any other position than those described above.

4. Installation

5. Connecting

Figure 5.1 Motorized change-over switch terminals

1. Terminals for motor operator voltage supply2. Control terminals (push buttons) 3. Terminals for state information of locking

Only an authorised electrician may perform the electrical installation and maintenance of motorized change-over switches. Do not attempt any installation or maintenance actions when a motorized change-over switch is connected to the electrical mains. Before starting work, make sure that the change-over switch is de-energised.

5.1 Control circuit

The control voltage (output C = 24Vdc) on the control terminal is non-isolated, see box 2 in Figure 5.1

When relay outputs are used with inductive loads (such as relays, contactors and motors), they must be protected from voltage spikes using varistors, RC-protectors (AC current) or DC current diodes (DC current).

Do not couple power for the control terminal. See the correct terminal for the power supply in Figure 5.1

6. Operating

6.1 Electrical controlThe motorized change-over switches are available for remote control.

To control the motorized change-over switch electrically:

1. Release the handle from the change-over switch panel by pressing down the locking latch under the switch panel and pulling the handle off, see Figure 6.1.

Electrical control is disabled if the handle is attached to the change-over switch panel.

Never open any covers on the product. There may be dangerous external control voltages inside the motorized change-over switch even if the voltage is turned off.

Never handle control cables when the voltage of the motorized change-over switch or external control circuits are connected.

Exercise suffi cient caution when handling the unit.

Figure 6.1 Releasing the handle

6. Operating

The motor operator is protected from overloading by a fuse (F1) under the motor operator. Only use the same type of fuse that is described on the label close to the fuse.

If a new command is given before the switch has reached the position of the previous command, the fuse (F1) may operate.

Figure 6.3 Impulse control

6.1.1 Impulse controlWhen using impulse control, the change-over switch is controlled by electric impulses. When you press the control button, the change-over switch is driven to the corresponding position (I, 0, II). The control impulse must last more than 100ms to take effect. A new command cannot be given until the change-over switch has reached the position of the previous command. Figure 6.3 shows the operation of the change-over switch with impulse control.

Figure 6.2 Motor/Manual selection switch in the Motor (M) position

3. Control the motorized change-over switch with the push-buttons via impulse control or continuous control.

2. Turn the Motor/Manual selection switch to the Motor (M) position, see Figure 6.2.

The continuous control command can be given with push buttons, cam switches or with relays incorporated in PLC equipment or with other suitable contacts.

6.1.2 Continuous controlWhen using continuous control, the control command is supplied to the switch continuously. When you press the control button, the change-over switch is driven to the corresponding position (I, 0, II). Control of position 0 will over-run control of the other positions; that is, if you simultaneously give the 0 command and another command, the change-over switch is driven to position 0. Figure 6.4 shows the operation of the change-over switch with continuous control.

6. Operating

Electrical control is prevented when the handle is attached to the change-over switch panel.

Figure 6.6 Attaching the handle

3. Control the motorized change-over switch by turning the handle to the required position (I, 0, II).

6. Operating

6.2 Manual operation using the handleYou can operate the motorized change-over switch manually by using the handle that is included in the delivery.

To control the motorized change-over switch manually:

1. Turn the Motor/Manual selector to the Manual (Man.) position, see Figure 6.5. The motor operator is switched off and electrical control is prevented.

Figure 6.5 Motor/Manual selection in the Man. position

2. Attach the handle by pressing it to the change-over switch panel until it clicks into place. You can attach the handle in both positions (I, 0, II), see Figure 6.6.

The following chart shows the locking state information (the voltage on motor operator supply needed).

6. Operating

6.3 LockingYou can lock the motorized change-over switch to a specifi c position.

6.3.1 Locking the electrical controlTo disable electrical control, lock the locking latch with a padlock. After the locking latch has been locked, the change-over switch cannot be controlled electrically. You can lock the electrical control to both positions (I, 0, II).

To lock electrical control:

1. Pull up the locking latch under the change-over switch panel.2. Place the padlock under the latch, see Figure 6.7.

6.3.2 Locking the manual operationBy default, manual operation can only be locked to position 0. Locking to position I and II is optional and possible only with modifi cations to the change-over switch panel.

To lock manual operation:

1. Turn the handle to the required position.2. Pull out the clip from the handle and place the padlock on the handle; see Figure 6.8

The handle cannot be attached when electrical control is locked.
