Input - Output
The MegaLine’s LCD display is able to give you all the information you need to manage
your UPS correctly without the need for a PC connection and the relative interface
software. What’s more, all the settings you may need can be programmed using the
display at the time of installation.
The INPUT section and OUTPUT section submenus keep the user informed of all the
sensitive data concerning the UPS operation. The active and apparent input and output
power, the input and output voltage and current, the frequency, the crest factor and the
power factor can be consulted at any time during mains operation by simply navigating
in two menus
Batteries
The BATTERIES menu provides important information both concerning the current status
of the batteries (charging voltage, residual capacity) and also a battery log. The number
of full discharges, the hours of use, the type of calibration in use, any extended runtime
kits or extra battery chargers tted, are all fundamental parameters when assessing the
life and usage of the batteries and for scheduling their replacement. It is also possible
to make a “Battery Calibration”, where the typical discharge parameters for the batteries
in use are acquired so this data can be applied to get a very accurate calculation of the
remaining runtime and recharge time.
Programming
With the MegaLine’s LCD display, it is very simple to schedule the automatic switching on
and o of the UPS, without the need to connect up a computer.
Even battery calibration and testing can be scheduled. A total of 16 programming
events can be stored in its memory with a Daily, Weekly, Monthly schedule or On
command.
Bypass
The BYPASS can also be scheduled to operate in a variety of ways.
• O -line: energy saving;
• Load waiting: the UPS switches on when the load exceeds the threshold set on the panel;
• Forced bypass: the UPS is excluded from the system.
The delay before intervention can also be adjusted to allow for repeated peaks of
consumption by the load by modifying the speed of the dipswitch (e.g. for laser printers
or photocopying machines).
Redundancy
N+X redundancy, on the other hand, is a warning function: if the parameter X=1,2
etc is set, the power of one module is reserved exclusively for redundancy and a
warning signal is provided should the load exceed the power available. For example:
MegaLine 3750 - Redundancy N+1 - load 2100 VA. 1250 VA of the available 3750 VA
is redundant, whilst the remaining 2500 VA is for use by the load. Should the load
increase in excess of 2500 VA, the UPS will signal that redundancy is no longer
available but continue to supply the load correctly.
