Section 5 – Procedures Battery Maintenance
E-0-2-2
Low battery voltage while charging. Algorithm
dependent. Typically 0.1V/cell.
▪
Another device may be drawing current from the battery.
▪
Check the battery voltage and cable connections.
▪
Check battery size and condition. Batteries may be
overdischarged.
▪
Use another charger to bring the batteries above the
minimum voltage.
▪
This error automatically clears once the condition has
been corrected.
E-0-2-3
High AC voltage error (>270 VAC)
▪
AC voltage is too high. Connect charger to an AC
source that has a stable AC voltage between 85 and 270
VAC/45-65 Hz.
▪
In newer software versions this does not prevent
charging.
▪
This error will automatically clear once the condition has
been corrected.
E-0-2-4
Charger failed to turn on properly
▪
Disconnect AC input and battery for 30 seconds. If the
error persists, contact Delta-Q Technologies.
E-0-2-5
AC voltage has dipped below 80 VAC 3 times in
30 seconds
▪
AC source is unstable. This could be caused by an
undersized generator and/or input cables that are too
long or too small.
▪
Connect the charger to an AC source with a stable AC
voltage between 85 and 270 VAC/45-65 Hz.
▪
This error will automatically clear once the condition has
been corrected.
E-0-2-8
Attempt to select algorithm incompatible with
this software
▪
Update charger software, continue to use existing
algorithm* or select a different charging algorithm that is
compatible.
* Notes
▪
If selecting a different algorithm, the existing algorithm
will remain in the charger.
▪
If upgrading an existing algorithm, the existing algorithm
will be deleted. Contact Delta-Q Technologies for a
software upgrade to run the new algorithm.
E-0-2-9
Cannot transmit on CAN bus
▪
Check the physical CAN connector, electrical bus
conditions, and other CAN modules for correct
functioning. For example, check that termination
resistance is approximately 60 ohms.
E-0-3-0
CAN heartbeat timeout on Battery module
▪
May be caused by a missing heartbeat message. Check
the CAN bus battery module for correct function.
▪
This error automatically clears once the condition has
been corrected.
E-0-3-1
The Vref for the ADC measurements
has triggered an alarm
▪
Internal charger error. Disconnect AC and the battery for
a minimum of 30 seconds and retry.
▪
If the problem persists, contact Delta-Q Technologies.
▪
This error automatically clears once the condition has
been corrected.
