Ambient operating temperature
-10 °C ... +50 °C
Storage temperature
–20 °C ... +50 °C
Air humidity
50 °C, 90% relative humidity (EN 61131-2)
Permissible operating height

2,000 m above sea level
Safe state
The safety-related semiconductor outputs are
in the OFF state (low).
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.
12.2
Response time
The response time of the safety system is composed of the following times:
•
Response time of the primary protective device (t
PrimaryProtDev
)
•
Response time of the logic (t
SafetyController
)
•
Response time of the relay(s) (t
Relay
)
The response time of the safety system is determined using the following formula:
t
SafetySystem
= t
PrimaryProtDev
+ t
SafetyController
+ t
