5.5.5ECO-mode

The UPS is equipped with the ‘ECO-mode’ feature. If the feature is enabled, the load is operated on utility through the electronic bypass switch. If the utility is interrupted or out of limits the load is automatically transferred to the inverter. Operating the load on utility improves the efficiency of the UPS with 5-8% and saves on energy costs. We advise not to use the ECO-mode in case of an unstable utility.

After enabling the ECO-mode (please refer to service screens 5.3.3) the standard menu changes to:

LP 5-11U
LOAD 37%	ECO

NOTE: If LP-U units operate in parallel, the ECO-mode feature is not available.

5.5.6Auto restart

If this feature is enabled and the unit has shut down (e.g. due to overload) the UPS will start up automatically when the normal situation is restored. The off-factory setting is: enabled.

If the auto restart feature is disabled the unit will not automatically restart when the normal situation is restored but the display will show:

AUTO RESTART OFF

PRESS ENTER

After ‘Enter’ the unit will restart. See also 5.3.3 ‘service screens’.

5.5.7Superior Battery Management

-Load dependent battery-end voltage: The allowable final battery voltage depends on the discharge

current: the higher the current, the lower the 'end-of-discharge' battery voltage. This gives maximum capacity without over discharging. Over discharging results in failure to recover normal capacity and in shortened battery life.

-Equalize mode: When switched on for the first time the UPS will start boost-charging the batteries for 15 hours in order to equalize all battery voltages.

-Boost mode: If after a discharge the battery voltage is lower than 240Vdc, the UPS will charge the batteries with a boost charge voltage of 285Vdc. This enables fast recharging of the batteries. The programmed battery charging mode will change from boost charge into float charge after boost charging twice.

-Temperature compensated battery charging: This feature reduces the battery charge voltage with increasing temperature (-18mV/°C or -32.4mV/°F per 12V battery). As a result poor charging of the batteries under low temperature conditions and overcharging of the batteries under high temperature conditions are prevented.
