START-UP & OPERATION
Once the FX system installation is completed, it is time to power the system. Leave the breakers on the AC side in the OFF position
until the FX’s are powered and programmed. Power the FX’s by switching the DC disconnect breakers to the ON position. The LED’s
(Light Emitting Diodes) in the AC compartment of each FX will begin to light. For each FX, one “BATTERY” LED will be lit. This
“BATTERY” LED should be either the green “FULL” LED or yellow “OK” LED. If the red “LOW” LED is lit, check the battery voltage and
the battery-to-FX cabling for reasons why the FX thinks the batteries are low. The other set of “STATUS” LED’s will begin to light. The
red “ERROR” LED may blink a few times, but this is just a symptom of powering the FX. About 5 seconds to 10 seconds after power is
applied, the green “INVERTER” LED will be lit with the “AC IN” and “ERROR” LED’s not lit.
At this point, the FX is producing an AC output voltage. If the user were to connect AC loads to the FX, the FX would use battery power
to power the loads. Before doing this, the programming of the FX should be performed using the MATE. If applicable, this
programming should include choosing the AC input type of grid or generator (generator is the default, see page 45 for more info),
stacking of multiple FX’s (see pages 24-26 & 53 for more info), adjusting the charging set points using the battery manufacturers
specification (see pages 23 & 48 for more info), setting the time and the date on the MATE (see MATE manual), and programming of
the Auxiliary output for the function you wish it to perform (see pages 51 & 52 for more info).
The FX system is now ready to perform per your specification. Switch the AC breakers ON with the bypass mechanism switched to
“Normal”. Provided that the AC source to the FX’s is available, the yellow “AC IN” LED in the AC compartment will begin to blink. If the
voltage of the utility grid is within 208 vac to 270 vac and the frequency is within 46 Hz to 54 Hz, the FX will connect to the utility grid.
This process takes about 30 seconds and the “AC IN” LED will stop blinking and stay lit.
When the “AC IN” LED is lit, the AC transfer switch within the FX is activated and the utility grid or generator power is applied to the
loads. At this time the FX will perform a complete charge on the batteries. This charging process will “Bulk” (raise) the battery voltage
until they reach the “Absorb” voltage. The FX will maintain this “Absorb” voltage for the “Absorb Time Period” (default of 1 hour). After
the “Absorb” stage, the FX performs a “Float” charge. It lets the battery voltage drop to the “Float” voltage and it then sustains this
voltage for the “Float Time Period” (default of 1 hour). Once the hour is up, the FX will go into “Silent” mode, essentially not charging.
