Incremental encoder specification
Never supply both incremental encoders using one supply cable!
The connection cables for the incremental encoders must each be in a separate plastic-
sheathed cable as otherwise a cable break could cause an error that could remain
undetected.
The power supply to the two incremental encoders must be independent. For this pur-
pose use the connection terminals provided, 19 and 20 as well as 21 and 22.
Each incremental encoder output (for 0° or 90°) is only allowed to be connected to one
control input, e.g. A1/B1 or A2/B2.
Both incremental encoders must meet the following specifications:
two-channel rotary encoder with 90° phase offset
supply voltage: 24 V DC
outputs: push/pull outputs
enclosure rating IP 54 or better
screened cable
max. pulse frequency: 100 kHz
min. number of pulses: 50 pulses per cm
You can procure suitable incremental encoders from SICK AG, tel.: +49 211/5301<250 or
at www.sick.com. Or contact your local SICK representative.
Control inputs
You can only connect the input signals to one safety laser scanner. Distributed connection
of the input signals to two safety laser scanners is not possible.
EFI systems
Connect EFI
A
on the first device with EFI
A
on the second device and EFI
B
on the first device
with EFI
B
on the second device.
Always use screened twisted pair cables!
If the length of the cable to the safety laser scanner is more than 30 m, the shield is to
be connected as close as possible to the device.
In an EFI system with two safety laser scanners, set the address of one of the scanners
to guest!
To differentiate unambiguously between the host and guest device in an EFI system, one
S300 must be configured as the guest. For this purpose a jumper is wired between the
connection terminals 7 (A1/INC1_0) and 13 (UNI-I/O3/ERR/WEAK).
The jumper always defines the guest device. This jumper is never allowed to be fitted on
the host device.
