5.15.3. LOAD SHED FREQUENCY DELAY (PICKUP)
Select the desired Load Shed time delay setting. The setting is entered in seconds
within. If no delay is required, set this time delay to zero.
5.15.4. LOAD SHED FREQUENCY PICK UP
Set to the desired Load Shed frequency pick-up set point as expressed in percentage of
nominal system frequency. The pick-up set point is the value which the internal sensor
energizes to a normal state when the load frequency rises above the set point to cause
a Load Shed condition to be reset.
5.15.5. LOAD SHED FREQUENCY DROP OUT
Set to the desired Load Shed frequency dropout set point as expressed in percentage
of nominal system frequency. The dropout set point is the value which the internal sensor
de-energizes to an abnormal state when the load frequency falls below the set point to
cause a Load Shed condition to be activated. A Load Shed frequency condition will be
triggered following expiry of the Load Shed frequency time delay setting.
5.15.6. LOAD SHED POWER (kW) DELAY (PICKUP)
Select the desired Load Shed time delay setting. The setting is entered in seconds
within. If no delay is required, set this time delay to zero.
5.15.7. LOAD SHED POWER (kW) DROP OUT
Set to the desired Load Shed dropout set point as expressed in percentage of rated
generator power. The dropout set point is the value which the internal sensor de-
energizes to a normal state when the load kW falls below the set point to cause a Load
Shed condition to be reset.
5.15.8. LOAD SHED POWER (kW) PICK UP
Set to the desired Load Shed pick-up set point as expressed in percentage of rated
generator power. The pick-up set point is the value which the internal sensor energizes
to an abnormal state when the load kW rises above the set point to cause a Load Shed
condition to be activated. A Load Shed condition will be triggered following expiry of the
Load Shed time over power delay setting.
5.16. IN-SYNC TRANSFER SET POINTS
The TSC 900 controller provides set points for in-sync transfer applications. To program the in-
sync transfer features, refer to the following descriptions:
5.16.1. IN-SYNC WAIT DELAY
The TSC 900 transfer control logic includes an adjustable time delay for maximum time
allowed to perform an in-sync transfer operation for Closed Transition type automatic
transfer Switches or Open Transition In-Sync ATS’s. If the selected time expires before
