There are three conditions that must be fulfilled in order to activate the safety contactors:
– The "software release" or "Control ON" signal must be issued.
– The EMERGENCY STOP loop must be closed.
– The start button must have been pressed.
2.7.4 EMERGENCY STOP loops and signaling circuit
2.7.4.1 EMERGENCY STOP loop structure
The following contacts are connected in series and form the EMERGENCY STOP loop:
– Make contact elements for the two protective cover switches
– Normally open (NO) contacts for the two EMERGENCY STOP buttons
– Make contact elements for the two changeover tables
2.7.4.2 Signaling circuit structure
The following modules in the signaling circuit are queried individually:
– The protective cover switches
– Signaling contacts on the changeover table
– EMERGENCY STOP button
All the signaling contacts are closed when the machine is on standby. If a protective cover, for
example, is lifted up, the associated signaling contact opens. This change of state is signaled to
the control computer via the CAN bus. An error message to this effect appears on the user inter-
face.
2.7.4.3 Description of the functions of the EMERGENCY STOP loops
The following conditions must be fulfilled in order to start and operate the machine:
– All changeover tables must be docked in and connected.
– All protective covers must be closed.
– Both emergency stop buttons must be released.
– The minimum operating pressure must have been reached.
– The software release ("Control ON") must be enabled, so that the start signal from the
"Start" button can activate the safety relay and safety units.
If one of the start buttons is now pressed, the safety contactors will be switched-on and the
machine is ready to use.

2.7.5 Hand guard (Dummy Feeder E)
2.7.5.1 Hand guard (Dummy Feeder E) at the locations
The hand guard is to be used when there is a gap in between feeders on the component table.
Slot the hand guard in the gap between feeders.
Push the hand guard until it touches the stop rail and the back of the feeder is in line with other
feeders.

WARNING
Operatio nal
Operational safety by occupying every second location!
The operational safety of the fixed table or changeover table in the E by SIPLACE is en-
sured if at least every second free location is occupied with a feeder module or hand guard
(dummy feeder).
Even when configuring manual tray carriers or a automatic tray changer, secure ev-
ery second location with a hand guard (dummy feeder).
