User Settings

For details of the User Settings, refer to the user setting information that is listed in the 9355 UPS User’s Guide.

Table 3. Disable control commands via communication user settings

Front Panel LCD User Setting Setting Definition To disable all control commands from a

communication channel. The setting is done independently per channel.

The control commands are all XCP commands that change/modify any parameters, variables, UPS operation, and so on in the UPS; or hardware commands that are multiplexed to communication receive lines, thus simulating a long break.

Display Contrast Adjustment The user can adjust the best LCD display contrast for the environment.

Change Language The language selection is between English and other languages.

Start Screen in the Display The default screen: Eaton Powerware logo or the mimic screen.

This screen is displayed at reset, when ESC is pushed until the system menu returns to the top, or when the display has been untouched for a specific time period.

User Settings Password Sets if the password is required for user settings.

Lock Communication to D-Sub Disables the automatic multiplexing of communication channel 2 between the X-Slot 2 and the D-sub, and directs the communication to D-sub permanently.

Setting Definition

Set Date & Time The date and time is used for time-stamping the history log items.

Serial Port Configuration The available speeds are 1200bps, 2400bps, 9600bps, and 19200bps, which are set independently per communication channel.

Go to Bypass The transfer is done only if bypass is available.

Battery Test Command When the test is launched with the XCP command, the test duration is given in the command. The test selected from the LCD has fixed time. The following is a

sample of a Battery Commissioning Test using command <ESC>B.:

BATTERY COMMISSIONING TEST BATTERY TEST # 1

TIME: 12:31:30 DATE: 11/14/2004 TEST 1 NOT COMPLETED

VOLTAGE 0.00

POWER (W/CELL) 0.00 TEST 2 NOT COMPLETED

VOLTAGE 0.00

POWER (W/CELL) 0.00 OPEN CIRCUIT VOLTAGE 0.00 CALCULATED RESISTANCE 0.0000 BATTERY HEALTH 0.0000

Audible Alarms The settings are:

Disable audible alarms and normal sound.

Set Nominal Output Voltage With XCP, the value can be set with 0.1V steps. The front panel setting has larger steps. Changing this value will automatically change the voltage window defined by Bypass Voltage High Limit and Bypass Voltage Low Limit.

Bypass Voltage High Limit The value is a positive percentage added to Nominal Output Voltage, and it follows changes automatically in the Nominal Output Voltage setting. It can be set with 1% steps, for example: +10%.

Bypass Voltage Low Limit The value is a negative percentage subtracted from Nominal Output Voltage, and it automatically follows changes in the Nominal Output Voltage setting. It can be set with 1% steps. Example: -15%.

Synchronization Window The value can be set with ±0.1Hz steps. This sets the frequency window used for synchronization around the Nominal Output Frequency, and it automatically follows changes in the Nominal Output Frequency setting.

Number of Battery Strings Zero (0) means that no batteries are connected.

Total battery size is number_of_strings × W/cells × cells/strings.

(W/cell, 15 min rate to 1.67 VPC at 25° C)

Battery Size Setting The size is given as Watts per battery cell, in 1W steps.

Total battery size is number_of_strings × W/cells × cells/strings.

(W/cell, 15 min rate to 1.67 VPC at 25° C)

Battery Low Alarm Level The maximum current used for charging the batteries is set with this setting, in 0.1A steps.

Automatic On Delay Values 0 ... 32767 define the extra delay in seconds,

turn on its output.

With value -1, the automatic restarts are disabled; the UPS will not turn on automatically (uncommanded) after low battery shutdown.

Nominal Output Frequency With an XCP command, the nominal output frequency can be set with 0.001Hz steps (the front panel has larger steps). Changing this value will move the Synchronization window in accord with it.

ABM Charging Cycling Disable Disables the cyclic ABM charging and uses the continuous mode.

Output Frequency Slew Rate The maximum speed of changing the output frequency that the UPS uses while synchronizing or maintaining synchronization; set with 0.1Hz/sec steps.

Operation Priority While Rectifier Input

Break This selects if the UPS will prefer bypass operation to battery operation when rectifier input fails, and bypass is available.

Rectifier Current Limit The maximum current drawn from utility by the rectifier is set here, in 0.1A steps.

Alarm Relay Configuration For each alarm, the user selects the relay to activate.

Signal Inputs Function For each alarm input, the user selects the function.

Input Signal Delayed Shutdown Delay This is the delay for hardware Remote off with automatic restart command.

Factory setting is 120 sec, but the user may modify it.

X-Slot Shutdown Signal Input Activation

Delay This is the delay duration the X-Slot hardware shutdown signal (connector pin 8) must be below before the associated function is activated.

Factory setting is 5 sec.

Unsynchronized Transfer to Bypass This selects if synchronization is required for making transfers to bypass.

Synchronization to Bypass This selects if the synchronization to bypass is done.

Usage of Bypass This selects if the bypass is used (enabled) when needed / required, or if it is never used (disabled).

Site Wiring Fault (NOTICE) The user can enable or disable this alarm.

When set as ”Disabled”, no alarm nor notice is given on the front panel. Nothing is logged into the history log.

When set as ”Enabled”, the factory setting is used, alarm activation and inactivation are logged.

Note: With Nodebits (service setting) it is possible to make a more detailed setting. The user setting (front panel) shows as ”Disabled” when set as event and not logged. Otherwise, the user setting shows as ”Enabled”.
