ALTERNATOR GP-CHARGING 3960901 - Caterpillar

Illustration 70 g01335558
This setting defines the minimum DC bus current that all MMUs are allowed to use for motoring the flywheels.Edit Walk-In Rate
Illustration 71 g01335560
This value is the rate at which the KW value of the load is transferred from the flywheel to the input when the MMU enters online mode from dicharge mode.Edit Overload Transfer Limit
Illustration 72 g01335563
The overload transfer limit sets the number of overload transfers to bypass that can occur within a ten minute period before the online mode is disabled without operator intervention.Edit Overload Warning Disable
Illustration 73 g01335564
You may disable overload warnings with the Overload Warning Disable selection. However, the overload timers will remain in effect.Edit GS Maximum Input Current
Illustration 74 g01335570
This setting allows you to set the maximum input current while the remote input from the generator is closed. This selection may be used with the GS Max Motor In Cuurent in order to prevent a generator overload when the generator rating is lower than the MMUs.Edit GS Maximum Charging Input Current
Illustration 75 g01335575
This selection allows you to set the charging input current during operation of the generator.Edit GS Maximum DC Bus Charge Current
Illustration 76 g01335578
This selection allows you to set the maximum DC bus charge current while the signal from a remote input is present.Edit GS Transient VAC Tolerance
Illustration 77 g01335582
You may set the transient VAC tolerance while the "On Generator" from a remote input is present.Edit GS Walk-In Rate
Illustration 78 g01335583
This setting allows you to set the walk-in rate while the "On Generator" signal is present. If the walk-in rate is set too high, the generator voltage can sag or slow down infrequency. These actions can cause the MMU to enter discharge before the walk-in is complete.Edit ATS Command Level
Illustration 79 g01335584
This setting is a flywheel percent energy setting. This setting controls when the ATS transfer command is given via a remote output relay. There are four conditions that must exist in order to execute the command:
MMU in discharge
MMU in discharge for more than one second
MMU not in walk-in
MMU flywheel percent energy is less than ATS Command Level (typical setting is 85%)Full load testing is recommended to ensure sufficient generator start times.Edit Auto Load and Start
Illustration 80 g01335586
This setting defines what the MMU does automatically when power is applied to the MMU after a complete outage.
0 = The UPS will require manual intervention to getr the UPS in bypass and online.
1 (default) The UPS will require manual intervention to get the UPS online. The UPS will power up in bypass.
2 = The UPS will go to the online state without any intercession.
