8.1 Application programs
General
The safety enable can only be given if all activated input circuits are
closed and the analogue input values are below the limit values.
The programs listed here are valid only for the standard
variant PROTECT SELECT and version 2.0 of the application
program (printed safety seal "Appl V2.0").
If the CRC of the following application programs described in
this document deviates from the indicated product program
CRC then the following information in this operating manual
does not apply.
When using the START/RESET button, requirements of the
DIN EN ISO 13849-1:2008, Chapter 5.2.2. (manual reset)
must be considered.
With a parameter setting of "Emergency-Stop":
The START/RESET button (I15) must be activated at all
events after "Power On".
If no feedback circuit (EDM) is evaluated, then the
corresponding input to 24VDC must be set to ensure the
safety function of the activated / deactivated safe analogue
inputs.
During the sequence of the after travel time (STOP 1)
the actuation of all START/RESET buttons is ignored.
In case of a voltage drop or a system failure, the device
shut off immediately without delay.
Sensor level: Safe digital inputs
In the following application programs, there is the possibility for the
specified free sensors to include the following safety switching devices:
• Emergency stop command devices, electronic and safety switches
with contacts, safety interlocks, proximity sensors, AOPDs, muting
sensors and 4-wire safety mats.
According to EN 60204-1:2006, a manual reset is necessary
after triggering the emergency stop. If the emergency stop
is configured with the option auto-start, a manual reset must
be realised by other suitable measures.
The number of free sensors depends on the program.
If all sensors have the auto-start option in a protective area,
then a START/RESET button for this protective area is not
necessary.
Sensors and emergency stop command devices can be
reset in any order.
Sensor level: Safe analogue inputs
Implemented in the following application programs for both analogue
secure inputs are the following functions, coupled to the 4 limit values:
1. Limit (AI0-0 and AI1-0):
Additional release interlock
2. Limit (AI0-1 and AI1-1):
No function implemented
3. Limit (AI0-2 and AI1-2):
No function implemented
4. Limit (AI0-3 and AI1-3):
Emergency Stop
Description:
• Additional release for the interlock:
If an interlock is parameterized and the two analogue input values are
below the first limit (AI0-0 and 0-AI1) and are among the remaining
limits, then the locking unit of the connected interlock can be unlocked.
• Emergency-Stop-Function:
If one of the analogue input values is above the fourth limit (AI0-3 or
AI1-3) then this corresponds to the triggering of the Emergency Stop.
Connect the non-required analogue inputs to AGND and
set the corresponding analogue limit values to 4095.
In the application programs, the error case of a wire break
in the analogue input is not controlled.
If it is necessary to control such the analogue input may
be used with the “Dual Sensor“ option.
Sensors and emergency stop command devices can be
reset in any order.
Actuator level
The actuator level for the subsequent application programs consists of:
1x p-/n-switching safe output Q0 / Q0N
2x p-switching safe outputs Q2 and Q3
2x Safe relay outputs QR1 and QR2
4x optional signalling outputs Y0 up to Y3
The number of shutdown paths depends on the application program
selected:
• There are a maximum of five shutdown paths available.
• Every safe shutdown path can have an individual shutdown delay
(Stop 1) assigned.
• The default times are set to 0.00 s, this means that the safe shutdown
paths are shutdown without delay (Stop 0).
The output times are allocated to the following timers:
