4.2 Mounting positions

The recommended mounting positions for OTM_ motorized change-over switches are horizontal, wallmounted or table mounted.

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

1SCC303002M9701

14


The electrical installation and maintenance of OTM_motorized change-over switches may beperformed only by an authorized electrician. Do not attempt any installation or maintenance actionswhen an OTM_motorized change-over switch is connected to the electrical mains. Before starting thework, make sure that the switch is de-energized.

1SCC303002M9701

Do not couple power for the control terminal. See the correct terminal for the power supply in Figure5-1.

The control voltage (output C = 24Vdc) on the control terminal is non-isolated, see box 2 in Figure5-1.

The maximum cable length to ensure faultless operation of the push-buttons, see table 7-1

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

1SCC303002M9701

16


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

Never handle control cables when the voltage of the OTM_ motorized change-over switch or externalcontrol circuits is connected.

Exercise sufficient caution when handling the unit.

6.1 Electrical control

You can control the switch electrically by using the push-buttons or a similar control concept.

To control the switch electrically:

1. Release the handle from the switch panel by pressing down the locking latch under the switch paneland pulling the handle off, see Figure 6-1.



1SCC303002M9701

17

21

A00

305A

Fig. 6-1 Releasing the handle

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

2. Turn the Motor/Manual selection switch to the Motor (M) position, see Figure 6-2.

Man.Man.

Fig. 6-2 Motor/Manual selection in the Motor (M) position

3. Control the OTM_ motorized change-over switch with the push-buttons via impulse control orcontinuous control.

The switch can be operated from position I to position II (or from II to I) without stopping it in position0. For example, if switch I is closed and you press the push-button (II), the control unit first runs switchI in the open position and then the control unit runs switch II from the open to the closed position.

1SCC303002M9701

18

The motor operator is protected from overloading by a fuse (F1) under the motor operator, see Figure2-1. Only use the same type of fuse that is described on the label close to the fuse.

6.1.1 Impulse control

When using impulse control, the switch is controlled by electric impulses. When you press the controlbutton, the switch is driven to the corresponding position (I, 0 or II). The control impulse must last morethan 100ms to take effect. A new command cannot be given until the switch has reached the position ofthe previous command. Figure 6-3 shows the operation of the switch with impulse control.

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

6.1.2 Continuous control

When using continuous control, the control command is supplied to the switch continuously. When youpress the control button, the switch is driven to the corresponding position (I, 0 or II). Control ofposition 0 will over-run control of the other positions; that is, if you simultaneously give the 0 commandand another command, the switch is driven to position 0. Figure 6-4 shows the operation of the switchwith continuous control.



1SCC303002M9701

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

6.2 Manual operation

You can control the switch manually using the handle that is included in the delivery.

To control the switch manually:

1. Turn the Motor/Manual selector to the Manual (Man.) position, see Figure 6-5. The motor operator isswitched off and electrical control is prevented.

6.3 Lockings

You can lock the OTM_motorized change-over switch to a specific position.

6.3.1 Locking electrical control

You can lock the electrical control to any position (I, 0, II).

To lock electrical control:

1. Pull up the locking latch under the switch panel.

2. Place the padloc k under the latc h, see Figure 6-7 .

6.3.2 Locking manual operation

By default, manual operation can only be locked to position 0. Locking to positions I and II is optionaland possible only with modifications to the 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 padloc k on the hand le, see Figure 6-8 .
