Hi! We have some KRC1 and KRC2 Robot still working on a 24/7 duty. We regularly change batteries but now it seems that, even if the batteries are always on charge due to the 24/7 job, they are not charged because every time there is a current interruption or we manage to turn off the power we lost the mastering. Replace the batteries with new one doesn't solve the problem. What should we check? Is there a special recharge circuit that need to be replaced?

Hi.
In KRC1 cabinet You have recharging modul situated in Powermodul PM600. In KRC2 cabinet there is specializated modul from Siemens to recharge batt.
On KRC1 You don't have visualization of state of batts. You have to measure current on working cabinet from PM600 to batts. On KRC2 it's simple because You have LED diode in the front of cabinet. If it's blinking it is sign that You have problems with proper working of batts (undevoltage etc.). On this Siemens modul You have info about problems with proper proces of keeping in a good conditions batts > fault diodes and working modes (time to keep shuting down process.Marek.
ps. Voltage is +27V without loading. -
in KRC2 there are three fuses at the bottom of the cabinet (just above batteries). They have no blown fuse indicator... check them out.
-
Also KRC1 and KRC2 with an RDW 1 are prone to the card coming to the end of its life and being unable to save the data.
If the cabinet seems to power down correctly eg stays on while shuttting down then it could the rdw is finished
You can RDW 2 no problems but big cost

Thanks for you kind answers. I want to focus on KRC1 problem. Is any check that I can do to verify the working contition of the charging module? For istance the +27V marek point out.

Hi.
Simply unplug "+" which goes to batteries and use multimeter to measure voltage which is going from Powermodul. If You have 27V on it there is problems with batteries. Checking voltage on batteries with multimeter is not proper, You have to check CURRENT.

ps. if You need schema for PM6-600 write on PM. -
Have a regular and Constant power supply. Use inverter. But still the battery problem remains sometime, then I think robot manufacturers wants us to purchase battery and keep back up always.

One thing is sure in my case. Furnish new batteries doesn't solve the problem and I have +26.9 <-> + 27 Vdc out the Power Module, no other variations. I'll try to change RDW1.
Thanks a lot...
