Ambient operating temperature
–10 °C … 50 °C
Storage temperature
–25 °C … 70 °C
Air humidity
90% at 50 °C (EN 61131-2)
Permissible operating height
2,000 m
Safe state
The safety outputs via the network are logic 0.
1)
The external supply voltage must jumper a brief power failure of 20 ms as specified in IEC 60204-1. Suit‐
able power supply units are available as accessories from SICK.

Response time of safety system
Composite response time
The response time of the safety system t
SafetySystem
is calculated as follows
t
safetysystem
= t
input
+ t
logic
+ t
output
t
input
Response time for the input of the gateway including the
response time of the safety laser scanner via EFI-pro. Consists
of:
•
Response time of the safety laser scanner via EFI-pro
1)
•
Network response time for data to the gateway
1)
•
2 x internal update interval for data from the gateway to the
main module
1)
•
General supplement: +5 ms
•
Deduction when using a 2nd gateway: –4 ms
2)
t
logic
2 × logic response time of the safety controller
t
output
Response time for the output of the gateway. Consists of:
•
2 x internal update interval for data from the main module
to the gateway
1)
•
Network response time for data from the gateway to the
robot controller
1)
•
General supplement: +8 ms
•
Deduction when using a 2nd gateway: –4 ms
2)
1)
You can find the value in the Safety Designer report.
2)
Only relevant if an additional gateway is integrated in the safety controller.
Complementary information
Changing the components of the safety system, the settings of the EFI-pro network, or
the logic program of the safety controller can affect the response time of the safety sys‐
tem. You may have to recalculate the response time of the safety system.
You must also take into account other times when calculating the stopping time of the
entire system. The following times are always relevant for the stopping time of the entire
system:
