The speed signals of the S300 or S3000 Expert are broken down into a 12 + 1 bit pat‐
t
ern: 12 speed bits and one bit for validation. These signals are available as input sig‐
nals, are duplicated and placed twice on the n:n function blocks (0 and 1 as well as 2
and 3).
The outputs of the function blocks are placed on EFI string 1 or on EFI string 2. As a
result they are available to all four safety laser scanners.
DANGER
Dangerous state of the machine
The “Speed valid” status information is relevant for safety.
b
Make sure that the “Speed valid” input signal is connected to the “Speed valid”
output signal.
Configuring the safety laser scanners in the CDS
b
In t
he CDS, on the Incremental encoder tab for the device to which the incremental
encoders are connected, select the Indicate velocity option.
All safety laser scanners, also the sending devices, must use these speed signals via
EFI.
b
For this reason activate the Use Flexi Soft CPU1 option on the Inputs tab for all safety
laser scanners.
b
Then select the Use velocity option on the Inputs tab for all safety laser scanners.
7.11.4 Multiple sampling
If multiple sampling is set, an object must be scanned several times before the S300
Mini St
andard switches its OSSDs to the OFF state or the S300 Mini Remote signals a
protective field interruption via EFI. In this way you can reduce the probability that
insects, welding sparks or other particles result in the shutdown of the system.
If a multiple sampling of 3 is configured, for example, an object must be detected in the
protective field three times in succession before the S300 Mini Standard switches the
OSSDs to the OFF state or the S300 Mini Remote signals Protective field interrupted.
DANGER
In t
he case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
The total response time is increased by the multiple sampling.
b
With a multiple sampling greater than 2, note that a supplement must be added to
the basic response time.
A multiple sampling of 2 is the minimum setting. The multiple sampling can be set to a
v
alue up to 16 using the CDS. The supplement to the basic response time resulting
from this setting is displayed in the CDS.
