Reconnect Delay Submenu
Utility Input 2/4
Reconnect DLY 7/7
5.0 Min
Reconnect Delay submenu defines the time that a Hybrid UPS system will continue
generating power in Emergency Mode before reconnecting to the utility grid. The turbine
checks that the utility grid voltage is within the protective relay settings for this time limit
before reconnecting to the grid. It is the minimum amount of time the system will operate
in Emergency Mode when the turbine is producing power. Initial Factory Setting is 5
minutes. The timer can be set from 5 to 30 minutes.
Load Output Connection Menu
The top-level Load Output connection menu establishes voltage and frequency output
from the Hybrid UPS microturbine in the Load LCM (LLCM), and is essentially the same
as for a normal microturbine operating in Stand Alone mode. It also establishes the
operational limits for voltage and frequency. These limits are usually set when the
MicroTurbine is commissioned and are not changed once set.
The Load Output submenus are detailed below:
NOTE
In the following submenus, the first line always displays the Stand Alone
top level menu.
Voltage Submenu
Load Output 3/4
Voltage 1/8
480 Vrms
Voltage submenu is used to view and set the nominal RMS output voltage (line-to-line) to
the critical load. Voltage is adjustable from 150 to 480 in one-volt increments. Initial
Factory Setting is 480 VAC line-to-line. The UPS Controller will set this voltage for all
Hybrid UPS systems operating in a MultiPac, and the user cannot change this value from
this Display Panel when the system is MultiPac enabled. Note that to change this value
from the Display Panel, the Hybrid UPS system must be MultiPac disabled and the user
must be logged in with the current password.
WARNING
Do not attempt to change any Stand Alone Protective Relay functions.
Injury to personnel and/or damage to equipment can occur. Contact your
Capstone Authorized Service Provider for additional information.
NOTE
All of the following Protective Relay settings can only be changed by an
Authorized Service Provider using CRMS.
