Hardware 8
• No communication between the bus card and base card.
Turn off the power and check that the base card is equipped with the correct bus interface
card. Cycle power on the actuator and check the following parameters in the “RESTRICTED”
menu routines:
— HW config: should be set to the “option” corresponding to the bus interface
present on the base card.
— Bus protocol: should be set to “I24” or “I20” according to the relevant bus protocol
instruction manual.
Hardware 9
• Reserved. Not used for ICON3000.
Hardware 10
• Reserved. Not used for ICON3000.
Hardware 11
• No communication between the bus (Profibus redundant card) and logic card. Turn off the
power and check that the base card is equipped with the correct bus interface card.
Cycle power on the actuator and check the following parameters in the “RESTRICTED”
menu routines:
— HW config: should be set to the “option” corresponding to the bus interface
present on the base card.
— Bus protocol: should be set to “I24” or “I20” according to the relevant bus protocol
instruction manual.
Hardware 12
• No communication between the encoder and logic card.
Turn off the power and check the encoder cable; if damaged, it must be replaced.
Cycle power on the actuator to check if the problem is corrected.
If the problem is not corrected, replace the Encoder. Cycle power on the actuator to check if
the problem is resolved.
If the problem is still not corrected, replace the Logic Card. Cycle power on the actuator to
check if the problem is resolved.
Hardware 13
• Encoder damaged or incorrectly configured.
Turn off the power and check the mechanical condition of the encoder. If damaged, it must
be replaced. Cycle power on the actuator to check if the problem is corrected.
If the problem still not corrected, replace the Logic Card. Cycle power on the actuator to
check if the problem is resolved.
