4.11.6 PULSE OUTPUT
PATH: SETPOINTS ÖØ S10 MONITORING ÖØ PULSE OUTPUT
The 489 can perform pulsed output of positive kWh and both positive and negative kvarh. Each output parameter can be
assigned to any one of the alarm or auxiliary relays. Pulsed output is disabled for a parameter if the relay setpoint is
selected as OFF for that pulsed output. The minimum time between pulses is fixed to 400 milliseconds.
This feature should be programmed so that no more than one pulse per 600 milliseconds is required or the pulsing
will lag behind the interval activation. Do not assign pulsed outputs to the same relays as alarms and trip functions.

4.11.7 GENERATOR RUNNING HOUR SETUP
PATH: SETPOINTS ÖØ S10 MONITORING ÖØ RUNNING HORU SETUP
The 489 can measure the generator running hours. This value may be of interest for periodic maintenance of the generator.
The initial generator running hour allows the user to program existing accumulated running hours on a particular generator
the relay is protecting. This feature switching 489 relays without losing previous generator running hour values.
