ABB AC500 PLC - Group Parameters for the Analog Part

Table 154: Settings "Error LED / Failsafe function"
Setting Description
On Error LED (S-ERR) lights up at errors of all error classes, Fail-
safe 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, Fail-
safe 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 parameters Behaviour analog outputs at communication error and Behaviour digital out-
puts at communication error are only evaluated if failsafe function is enabled.
