Wiring of the actuators
using a 40pin front connector
* Outputs must be protected by a 250 V fast-blow fuse (recommended fuses: Wickman
194-1100 1.1 A and Littlefuse 0217-800 V 800 mA.)
When mounted in a hazardous area to National Electric Code (NEC), always remove the
fuse when the module is outside of the potentially explosive atmosphere, and use a suitable
tool.
Configuration in RUN
Special considerations must be given if you use the Configuration in RUN function.
SF LED is lit:
Status before re-configuration diagnostics on, SF LEDs lit among others (on CPU, IM or
module), although diagnostics are no longer pending and the module is operating correctly.
Solution:
● Only change the configuration when no diagnostics are pending for the module or
● Pulling and plugging the module.
