OPERATING PROCEDURES
Controller and Rectifier
For operation instructions on these units, refer to the following documents.
•Mini Control Unit Instructions (UM1M831ANA)
NOTE! The controller’s default “User Name” is "admin" and the default “Password” is “640275”.
•Rectifier Instructions (UM1R481000e3)
Controller Battery Charge Current Limit Feature
Functionality: After a failure of the input source (commercial AC) or when some battery cells are permanently
damaged, the current to the batteries can be quite extensive. To avoid overheating or further damages to the
battery, the controller can be programmed to limit the battery current to a preset level by limiting the charging
voltage of the rectifiers. Should the battery current still exceed a higher preset value, an alarm is issued.
The controller limits the current going to the batteries based on the “Battery Current Limit” set point which is a
percentage of the battery capacity in C10. For example, 0.1C10 would mean 10% of the battery capacity.
Refer to the mini control unit Instructions (UM1M831ANA) to program this feature. Battery charge current is
limited to the value set in the controller, as long as battery voltage is above 47 VDC.
Local Controls and Indicators

TROUBLESHOOTING AND REPAIR
Contact Information
Refer to Section 4154 (provided with your customer documentation) for support contact information.
Controller and Rectifier
For troubleshooting and repair instructions on these units, refer to the following documents.
•Mini Control Unit Instructions (UM1M831ANA)
•Rectifier Instructions (UM1R481000e3)
Controller Configuration
If any controller configuration settings were changed, refer to the mini control unit instructions (UM1M831ANA)
and save a copy of the configuration file. This file can be used to restore the controller settings, if required, at a
later date.
NOTE! Provided on a USB drive furnished with the system is a controller configuration drawing
(C-drawing) and the controller configuration files loaded into the controller as shipped.
System Troubleshooting Information
General
This system is designed for ease in troubleshooting and repair. The various indicators as described in the
controller and rectifier instructions are designed to isolate failure to a specific element. Once the faulty element
has been identified, refer to “Replacement Information” on page 16 and “Replacement Procedures” on page 16.
Troubleshooting Alarm Conditions on the Controller
The controller displays alarm conditions as listed in the “Resolving Alarms” section of the controller’s user
manual. Programmable external alarm relays are also available. Refer to the system installation instructions
(IM582138000) and the controller configuration drawing (C-drawing) supplied with your power system
documentation for your alarm relay configurations.
The controller’s Active Alarm and Alarm History submenus allow the user to view alarm details. Refer to the
mini control unit instructions (UM1M831ANA) to access these menus.
Checking the Controller’s Current Limit Point after Adding or Removing a Rectifier
If a rectifier module is added; the respective current limit point in amps will automatically increase to maintain
the same percentage. For example, if the current limit was set to 100% of combined capacity and a rectifier
module is added, the new current limit setpoint will be 100% of the combined capacity including the new
rectifier module.
If a rectifier module is removed from the system (and the Rect Comm Fail is cleared), the current limit point will
remain unchanged unless the capacity of the remaining rectifiers is not sufficient to maintain this current limit
point. If that happens, the current limit point will automatically decrease to the maximum (121% of the
remaining rectifiers).
It is recommended that the current limit point be checked whenever a rectifier is added to or removed from the
power system.

Vertiv |NetSure™ 2100 Series -48 VDC Power System User Manual (UM582138000)|Rev. A
16
When setting total rectifier current limit, the set point to each rectifier is the total set point divided by the
number of rectifiers. For example, if the system contains three rectifiers and the current limit is set to 30 amps
then each rectifier has a current limit set point of 10 amps. If one or more rectifiers are removed or fails it will
take several seconds for the individual set points to the remaining rectifiers to be reset. In the example given, if
one rectifier is removed the current limit set point will drop to 20 amps (10 amps times two remaining rectifiers)
until the controller can send updated set points to the remaining rectifiers. This takes a couple communication
cycles (several seconds) after which each rectifier would have a new set point of 15 amps for a total of 30 amps.
The total current limit of the rectifiers should not be set such that the loss of the redundant rectifiers will cause
this temporary set point to drop below the actual maximum expected load. If batteries are used on the rectifier
output, the batteries should support the load until the current limit set points can be re-established due to loss
of a rectifier.
Refer to the mini control unit instructions (UM1M831ANA) for a procedure.
Clearing a Rectifier Communications Fail Alarm after Removing a Rectifier
If a rectifier module is removed from the system, a rectifier communications failure alarm is generated. If the
rectifier module will not be replaced, the alarm should be cleared.
Refer to the mini control unit instructions (UM1M831ANA) for a procedure.
Clearing a Rectifier Lost Alarm
If the controller resets while a rectifier communications fail alarm is active, the rectifier communications fail
alarm is replaced with a rectifier lost alarm.
Refer to the mini control unit instructions (UM1M831ANA) for a procedure to clear the alarm.
Replacement Information
Replacement Assemblies
When a trouble symptom is localized to a faulty rectifier, controller, or system circuit card; that particular device
or circuit card should be replaced in its entirety. No attempt should be made to troubleshoot or repair
individual components on any rectifier, controller, or circuit card.
