[180] Clock Fault The clock function has been reset todefault (2000-01-01) because of a powerfailure.[181] PreventiveMaintenance1 or more of the preventive maintenanceevents programmed inparameter 23-10 Maintenance Item haspassed the time for the specified action inparameter 23-11 Maintenance Action.[193] Sleep Mode The frequency converter/system hasturned into sleep mode. See parametergroup 22-4* Sleep Mode.[194] Broken Belt A broken belt condition has beendetected. This function must be enabledin parameter 22-60 Broken Belt Function.[196] Fire Mode The frequency converter is operating inFire mode. See parameter group 24-0* FireMode.[198] Drive Bypass To be used as signal for activating anexternal electromechanical bypass,switching the motor direct on line. See24-1* Drive Bypass.CAUTIONIf enabling the drive bypassfunction, the frequency converter isno longer safety certified (for usingthe Safe Torque Off in versionswhere included).The below setting options are all related to the cascadecontroller.Wiring diagrams and settings for parameter, see parametergroup 25-** Cascade Pack Controller for more details.[200] FullCapacityAll pumps running and at full speed.[201] Pump1RunningOne or more of the pumps controlled by thecascade controller are running. The functionalso depends on parameter 25-06 Number ofPumps. If set to [0] No, Pump 1 refers to thepump controlled by relay RELAY1 etc. If set to[1] Yes, Pump 1 refers to the pump controlledby the frequency converter only (without anyof the built-in relays involved), and Pump 2 tothe pump controlled by the relay RELAY1.
