LIQUID CRYSTAL DISPLAY (8)

The Liquid Crystal Display (LCD) touch panel indicates power flow, measured values, operational guidance, data
records and error messages. The LCD panel has a back-light which facilitates viewing in different ambient lighting
conditions. The LCD will automatically clear and turn off, if the screen is not activated within 3 minute period. The LCD is
turned back on when it is touched again. The LCD ERROR indicator is cleared after 24 hours and can be reproduced by
pressing any key on the panel.

Test Mode Options

Several parameters and functions are available if they are enabled by a Toshiba Field Representative while the UPS is in
Test Mode.
4.3.1.1 Battery Equalize Charge
The UPS "Equalize Charge" parameter is disabled by default unless the unit is sold with a wet cell battery system.
The "Equalize Charge" button can be enabled by a Toshiba Service Representative while the UPS is in Test Mode
(Battery Run Setup). Once enabled, the "Equalize ON/OFF" button is located under OPERATION / SETUP.
To Initiate the Equalize Charge battery function, press the "Equalize ON/OFF" button. Equalize Charge will boost the
charge voltage (500-640V) for the length of time (0-100 hrs.) specified during setup.
4.3.1.2 Battery Self Check
The UPS "Battery Self Check" function provides a periodic battery self-check at preset intervals. The parameter is
enabled by default.
The adjustable Self Check cycle ships with a default setting of 720hrs. The minimum interval is 5 hrs.
When the Self Check is initiated, the converter contributes 5% of the load to the inverter for up to 200ms. If the
batteries cannot reach and contribute 5% of the load or if the battery voltage falls out of tolerance, the unit will end the
test and set an alarm.
