Position the reset button outside the danger zone so that it cannot be activated from the protective fields
and danger zones. The operator must be able to see all danger zones from this position.
Identify the area to be released on the reset button so that its meaning is clear and easy to understand.
Ensure that nobody is in the danger zone before pressing the reset button.
Hold down the reset button for between 0.12 s and 4 s to enable the safety-related switching outputs.
Start interlock
The
start interlock
function prevents the machine from starting automatically after switching on or after the
supply voltage returns.
The machine only starts when you press the reset button.
Restart interlock
The
restart interlock
function prevents the machine from starting automatically, as soon as the protective
field is free again. The
restart interlock
function always includes the
start interlock
function.
The machine only starts again when you press the reset button.

Reference contour monitoring
The
reference contour monitoring
function prevents unintentional misalignment and deliberate manipula
-
tion of the safety sensor. If a protective field contains an area with reference contour, the safety sensor not
only monitors interruptions of the protective field, it also monitors the concurrence of the measured area
contour with the set reference contour. If the measurement values of the area contour deviate from the
defined reference contour by more than the tolerance zone of 200 mm, i.e., if no object is detected in the
area with reference contour, the safety sensor switches off and the safety-related switching outputs
(OSSDs) switch to
off
.
Activation of the function
Activate the
Reference contour monitoring
function together with the definition of the protective field
boundaries using the configuration and diagnostics software (see chapter 9.4.4 "Creating and configur
ing protective/warning field pairs").

5.8
EDM contactor monitoring
The
EDM contactor monitoring
function dynamically monitors the contactors, relays or valves connected
downstream of the safety sensor. Prerequisites for this are switching elements with positive-guided feed
-
back contacts (normally closed contact).
Activation of the function
Activate the contactor monitoring function using the configuration and diagnostics software (see
chapter 9.4 "Configuring protective function").
If contactor monitoring is activated, it operates dynamically, i.e., in addition to monitoring the closed feed
-
back circuit every time before the OSSDs are switched on, it also checks whether the feedback circuit has
opened within 500 ms after release and whether it has closed again within 500 ms after the OSSDs
switched off. If this is not the case, the OSSDs return to the OFF state after being switched on briefly.
A message is displayed on the alphanumerical display and the safety sensor switches to the fault interlock
state:
• With the OSSDs switched off, +24 V must be present at the EDM input.
• With the OSSDs switched on, the EDM circuit must be open (high impedance).
DANGER
Risk of death if start/restart is operated unintentionally!
Ensure that the reset button for unlocking the start/restart interlock cannot be reached from the danger
zone.
Before unlocking the start/restart interlock, make certain that no people are in the danger zone.
