4.5.2 E-stop System
The E-stop safety equipment found on the Mobile Panel meets EN418 requirements and can be
used together with a corresponding monitoring system for safety-relevant control tasks (up to
category 4 according to EN 954-1).
Connection examples for the E-stop button and the key switch for various categories (EN 954-
1) can be found in chapter 3 "Start-up / Operation", section "Connection Examples for the E-stop
and Key Switch", on page 86.
4.5.3 Enable Switch
The enabling equipment consists of the enable button as seen in figure 23 "Handle
4MPHDL.0000-00" on page 59 and is part of the Mobile Panel safety equipment.
Obtaining safety category 4 according to EN 954-1 is possible through the implementation of
enabling equipment with 2-circuits and using a corresponding monitoring device.
The enabling functionality is described in EN60204. The 3-step enable switch is state-of-the-art
technology. The "Null" and "Panic" positions on the enable switch represent off functions. Only
the "Enable" position allows activation. The standards EN60204 and IEC60204-1 are identical,
which provides the 3-step enabling switch with international significance.
Danger!
• When unplugged, the Mobile Panel must be kept away from sources of
danger on the machine or system and must be locked away. An E-stop that is
not connected must be kept out of sight for the user because the closest E-
stop will be pressed if a dangerous situation occurs and, when unplugged,
this E-stop does not function.
• The E-stop must be effective in any operating mode on the machine or
system.
• Deactivating the E-stop is not permitted to cause an automatic restart.
• The E-stop is not a replacement for safety equipment.
• If the machine or system was brought to a standstill using the E-stop button,
the E-stop button is only to be deactivated and the system being monitored
is only to be restarted after the reason for stopping has been corrected and
the dangerous situation no longer exists.
Caution!
Dropping the Mobile Panel can trigger the E-stop button and cause the system being
monitored to come to a standstill.
