1) If less than 24V is present across the battery:
(a) Batteries are not accepting the charge
OR
(b) Battery capacity is too large for the BC-35
and the number of BE-35s being used
2) If more than 30V is present across the battery:
(a) Batteries used have high internal impedance
OR
(b) BC-35 is not shutting off the charge state at
the required voltage point
If the BC-35 is not providing a charging current, test
pin 1 of the P1 plug on the BC-35 module in reference
to the negative side of the power supply. If there are no
volts at this point, replace the BC-35 module. If there
are more than 2 VDC at this point, and no alarm is
present, replace the CP-35 panel.
This information is provided to assist you in diagnosing
relatively routine problems. There may be extenuating
circumstances involved which are not covered here. If
further assistance is needed, please contact your Regional
Engineer or the Siemens Industry, Inc., Technical Support
Group.
WARNING:
The BC-35 has been factory set for the bat-
teries specified. Any alteration or adjust-
ment to this module will void both the UL
listing and the Manufacturer’s Warranty and
may cause damage to the battery.
