ABB AC500 PLC - Group Parameters for the Digital Part

Table 175: Table Error LED / Failsafe function
Setting Description
On Error LED (S-ERR) lights up at errors of all
error classes, Failsafe-mode off
Off by E4 Error LED (S-ERR) lights up at errors of error
classes E1, E2 and E3, Failsafe-mode off
Off by E3 Error LED (S-ERR) lights up at errors of error
classes E1 and E2, Failsafe-mode off
On + Failsafe Error LED (S-ERR) lights up at errors of all
error classes, Failsafe-mode on *)
Off by E4 + Failsafe Error LED (S-ERR) lights up at errors of error
classes E1, E2 and E3, Failsafe-mode on *)
Off by E3 + Failsafe Error LED (S-ERR) lights up at errors of error
classes E1 and E2, Failsafe-mode on *)
*) The parameter Behaviour DO at comm. error is only analyzed if the Failsafe-mode is ON.
