Safety and Signaling Circuit

The safety circuit consists of three safety combinations, which work completely independently of each

other. They are used to monitor the following actions:

▪ Actuation of the EMERGENCY STOP button

▪ Opening the protective door of tower 1

▪ Opening the protective door of tower 2

Position of the protective door switches

These switches check whether the two protective doors

are closed. If the doors are closed, the safety contact and

the signaling contact are closed. When one of the doors

is opened, the safety circuit and the signaling circuit are

opened. The corresponding safety combination is

triggered and the tower is powered down. The following

error message appears: “Tower x: Protective door not

closed”.

Position of the combination circuit breakers

The combination circuit breakers are fitted on the rear of

the masterdrive housing. In the event of malfunctions that

are relevant to safety, they are triggered.

Overview Operational Safety

The two protective doors are each equipped with a protective door switch. These are looped into the

starting circuit of the respective monitoring device.

If the EMERGENCY STOP button is pressed during operation or one of the two protective doors opens,

the relevant safety combination is tripped and the drives are locked via contactors on the electronics

board.

The signaling circuit for the protective door monitoring system is transmitted to the MTC2 controller by

the relevant safety combinations, via normally open contacts.

13.2 Construction and mode of operation

The MTC2 extends the capacity of a SIPLACE station to supply components by up to 100 JEDEC waffle

pack trays. It has its own controller (C167 controller board) and is integrated into the station computer

software. The setup of the MTC2 is integrated into the line controller software of a system.
