Tested successfully: Use under extreme ambient
conditions
The AXC 1050 XC controller has been tested successfully over 250 temperature change
cycles according to IEC 61131-2 in the range from -40°C to +70°C.
The following conditions were observed:
–
The Axioline F devices for all connecting cables were wired with a minimum conductor
cross section of 0.5 mm
2
.
–
The controller was installed on a wall-mounted horizontal DIN rail.
–
Fans were used to ensure continuous movement of air in the control cabinet.
–
The controller was not exposed to vibration or shock.
–
The controller was operated with a maximum of 24.5 V (ensured by using electronically
regulated power supply units).
