MX60 Remote Battery Temperature Sensor

Post by Zip92 »

Is the MX60 compatible with the remote battery temperature sensor? Or must you manually adjust for compensation in the settings?

From the MX-60 Manual:

Tmp Comp :
Battery temperature compensated Absorb and Float set points. The set points will rise when
the battery is cold and will be reduced when the battery is hot. If no external battery
temperature sensor is available these settings will equal those found in the charger setting
screen.

WIDE /LMIT:

WIDE (default) covers the normal battery temperature compensation voltage range.
LMIT mode limits the Upper and Lower battery temperature compensated voltage range.

Thanks Provo.
I have one temperature sensor connected to my hub. Do you know if the MX60 will fetch the temp data from the same sensor that my VFX CC’s use; or does it need its own sensor directly connected to the MX60?

fcwlp said in another thread:

"I forgot that you have a MX60 and not a FM60. The Mate3/3s can read data from the MX60 but not control it. It is not clear if this requires one or two BTSs. Easy way to test next time is to plug the BTS into the MX60 and read the reported temp on OpticsRE or the Mate3s...."

Try it out, and let us know!

I also have an MX60 but I have the RTS plugged into my inverter on port 01. The Mate shares the temperature compensated battery voltage with all OB products connected to my hub, including the MX60. Only one RTS is needed.

Mike thanks for confirming this.
