[EVDL List]

I have a new PFC 30 charger with MKIIc regs and 18 Exide orbitals all
connected to the reg bus. The pack is charged for the most part and I
could benefit from a simplified version of setting the pack
acceptance voltage on the charger.

Besides a quick and dirty on this here are some questions:

1) Exactly how "charged" should the pack be before making the
acceptance setting? Specifically to insure proper setting or is this
not that critical.

2) What due diligence should be done to insure regs are working
correctly?

3) I was told that turning the number 6 switch on the charger to the
high setting would light up all the regs as a quick test to make sure
the reg buss wires are all working but that did not work. I believe
there is another test ( connecting two pins and all the XX LED's
light? Just want to confirm the com connections



Any techniques or learnings would be appreciated.



Thanks,


Mark

[EVDL List]

1) The pack needs to be fully charged.

2) a) All the regs blink when the charger is set to 1 amp
b) Each battery voltage is in the high 14's (14.5 to 14.99 depending on
temperature).
c) Shorting the temperature sensor pins turns off the charge current.

3) Switch 6 grounds pin 3 on the Regbus. Shorting the temp sensor pins on
each regulator will short pin 3 to ground (pin 4) as well. When pin 3 goes
to ground, all the Yellow LEDs should light. If the LEDs never illuminate,
check for 5 volts from pin 1 to pin 4 on the Regbus. If the 5 volts is not
there, unplug the Regbus from the charger and check for voltage at the
charger. If there is no 5 volts coming from the charger, the power supply
for the Regbus is not functioning and needs repaired. If there is 5 volts at
the charger, plug one reg into the charger and check for 5 volts again. If
the 5 volts is there, turn on switch 6 and the Yellow LED should light. If
this one reg turns on the Yellow LED, then connect others to it, one at a
time. If you plug one it and it does not come on, there is an open cable. If
you plug one in and all the LEDs go off, then you have a shorted cable.

I hope this helps.
