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.

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.
