Toshiba 1000 manual Free Run Mode, Diagnostic Tests, System Configuration

Alternating between bypass and on-line modes is achieved automatically and in accordance with the conditions of the utility power. On-line mode may be used during times of utility power irregularities. The bypass mode should be used when power flows smoothly in order to obtain the greatest efficiency. Irregularities can be detected in less than a second and the on-line mode can be reactivated immediately. Switching back to online mode occurs when the input voltage exceeds ±10% (or ±15% selectable), when the input frequency exceeds ±3Hz, or when no input line is available.

Although high efficiency is standard, the default operation is the on-line mode. From the LCD display panel, Bypass can be activated as required or On-line operation can be run permanently if preferred.

2.3Free Run Mode

Free run mode is a mode of operation in which the output frequency does not match input frequency. The UPS operates in free run mode when the input frequency is outside of the selected input frequency range. When starting the UPS, the targeted frequency is 50 or 60 Hz ±0.25Hz. Refer to Section 4.3 to set up bypass availability while running in free run mode.

2.4Diagnostic Tests

When the UPS is started, a diagnostic test is executed automatically that checks the electronics and battery, and reports any problems on the LCD display.

The advanced battery management system monitors the performance of the battery and will indicate if battery replacement is required. The battery management system tests the battery every 30 days of normal mode operation. A battery discharge test is performed and reports any problems on the LCD display.

Except during the first 24 hours after startup while the UPS is in charging mode, diagnostic tests can be performed manually from the front panel when required.

2.5System Configuration

The UPS device and the internal backup battery make up the system. Depending on the site and load requirements of the installation, available options may be utilized to create a tailored solution.
