FM60 AUX: Low Battery Disconnect

Postby tomb920 on Sun Jun 07, 2009 8:09 pm

Hi All,

I don't know but it seems my AUX feature on FM60 is not working properly with the user defined settings. I have setup the AUX:Low Voltage Disconnect @ Disconnect = 48.4V / Reconnect = 50.4V / Delay Time = 1. A pilot LED lamp is currently conected at the AUX port and its working. When the AUX is set to "OFF" there is no light (normal). When its set at "ON" light is on (normal), but when its is set to "AUTO" mode, the lamp still is lighted up even when the voltage is greater than reconnect voltage (50.4 or >52). What could be wrong? I wanted to hook up a relay to switch back loads to grid power when on low voltage.

Other AUX modes are set to off.
Inverter is running when I setup the AUX.

Many thanks,
Tom

Tom,

This sounds like normal operation to me.

Using your settings in AUTO mode, the test light should turn off when the battery voltage drops below 48.4 V (disconnect setting). It should stay off until the battery voltage hits 50.4 V (reconnect setting). It should then stay on as long as the battery voltage remains above 48.4 V.

HTH,

Hi,

I want to protect the battery bank for over discharge. How to hook up a relay between MX80 and the battery bank? and how to set up the low voltage disconnect function on the Mate2 ?

Many thanks!

On the Mate, press soft keys for the following on the screen:

MAIN--------------------------
ADV
ADV/PASSWORD----------------
ADV
FX
INV
DOWN
DOWN
DOWN

This will get you to the screen/Page :

ADV/FX/INVERTER-------P00
low battery 10.5 vdc (for a 12V system)
cut-out set point

Press the INC or DEC soft key to set the cut out voltage you desire.

Note, from the manual (page 11) :

low battery cut-out establishes when the FX turns
off to avoid draining the battery. If an AC source
is available and AC INPUT is set to DROP, the FX
will transfer the AC loads on the FX to the AC
source. A built-in five-minute delay reduces
nuisance FX shutdowns. This setting’s range is
between 9.0VDC and 12.0VDC.
