4.6 Threshold & Default Values
The following table shows the factory set threshold/default values internally stored in the PSR312 unit
(for lead acid battery):
Default values
Output voltage Vo (V
DC
Over voltage V> (V )
DC
Current limiting Iconst (A
Note: The threshold/default values can only be changed in combination with an UPC DC controller unit.
If an UPC DC controller unit is controlling the power supply unit through the CAN-Bus, the charge voltage
is completely controlled by the UPC based on its configuration values and momentary charge state (for
example temperature compensation, boost charge, or battery test). That means that the values sent
from the UPC over CAN-Bus have top priority. During CAN-Bus communication the internally stored
values of the rectifier are invalid.
But when the CAN-Bus connection is inactive for more than five seconds (e. g. due to trouble), the
PSR312 automatically switches back to the internally stored default values. In this case it is ensured
that the battery is charged in the float charge mode.

4.7 Default value setting for NiCd batteries

If the rectifier is to be used to charge NiCd batteries the default/threshold values must be set according
to the individual battery type using a CAN dongle and PC software (see section 3.2 "Available Options
and Assembly Equipment"). A specific manual is available on request. For the adjusting range of the
output voltage please see section 8 "Technical Specifications".
