4.3.2 To Set Alarm Setpoints

The levels at which alarms operate are adjusted by the alarm setpoint parameters AL1, AL2 or AL3. By default, these can only be set in Operator Level 2, (section 4.6.2). If the controller is configured to measure load conditions (section 5.2.12), parameters Ld.AL, LE.AL, Hc.AL are used to set alarm setpoints for load currents.
