Protective Doors
Both towers have a protective door. When you open the
protective door, the tower is powered down. The following
error message appears on your screen:
Tower x: protective door not closedThe other
tower continues to work until it completes its cycle. Once
the protective door is closed, the cycle must be restarted.
CAUTION! Do not open the protective doors of
the MTC2 unless you are informed to do so on the screen
of the station computer or when the MTC2 has been
switched off.

Legend
1. EMERGENCY STOP button
The EMERGENCY STOP button is a self-latching
combination and designed with bypass protection
according to EN 418. This red, mushroom-shaped button
remains depressed when you press it.
When you press the EMERGENCY STOP button, the
entire line, with SIPLACE station and MTC2, is
immediately stopped. Placement is interrupted and, once
the machine is in working order again, can be resumed or
canceled. Watch out for any incompletely assembled
printed circuit boards.
Pressing the EMERGENCY STOP button opens the two
switching contacts of the safety circuits; the relevant
safety combination is triggered. The intermediate-circuit
voltages (500 V) for the inverters are disconnected. Both
the lifting and feed axes are deactivated while the logic
circuitry of the inverters continues to be supplied with 24
V DC. The following error message appears on your
screen: EMERGENCY STOP operated will be shown on
the screen.

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.

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.
