If it is not clear which drive is associated with which main switch, an additional maintenance switch is required close to each drive.

Maintenance switches (safety switches) with auxiliary contacts

T0-3-15680

P1-25/.../P1-32/.../P3-63/.../P3-100/.../...N/NHI11

Maintenance switches are fitted to electrical machines or installations to provide safe working conditions in accordance with the safety regulations.

By attaching his own padlock to the SVB padlocking feature, the electrician can protect himself against anyone switching on without authorization (￫ Section ”Circuit diagram example for maintenance switches with a load shedding contact and (or) switch position indicator”, page 4-4).

T0(3)-3-15683 circuit symbol

Function

Load shedding: When switching on, the main current contacts close first, then the contactor is activated via the late-make N/O contact. When switching off, the contactor is first disconnected by opening the early-make contact, then the main contacts isolate the motor supply.

Switch position indication: The position of the switch can be signalled to the control panel or control room via additional NO and NC contacts.

Interlock circuits

Interlock circuits between cam switches and contactors with overload relays provide neat and economical solutions for many switching drive tasks. The following points are common to all interlock circuits:

• Protection against automatic restarting after a motor overload or voltage failure

• The facility for remote disconnection (e.g. emergency-stop) can be provided by one or more Off pushbuttons.

Without mains disconnection (SOND 27)Mains disconnection only by contactor primarily for star-delta connection

With mains disconnection (SOND 28)Mains disconnection by contactor and switch

Interlock with contactor (SOND 29)Contactor can be energized only when switch is in an operating position

Interlock with contactor (SOND 30)Contactor can be energized only when switch is in an operating position
