INSTALLATION & OPERATING MANUAL
Manual No. x75-10b

DC WALK-IN
ON (Default) – Causes the controller to slowly ramp up the DC rectier voltage when
AC is applied. The voltage will rise from approximately 45V (for 48V systems), 22V
(for 24V systems) and 11V (for 12V systems) up to the oat voltage. The ramp-up
time is several minutes and cannot be adjusted. The purpose of this feature is to
avoid initially large battery charging currents.
OFF – Causes the controller to program all rectiers to the oat voltage almost
immediately after AC is applied. Battery charging current will only be limited by
the current limit of the rectiers.”
EXTERNAL TEMPERATURE SHUTDOWN
This facility is for use ONLY with the special Load LVD conguration described
in appendix 2.
THIS FACILITY
MUSTNOT BE ENABLED IN ANY STANDARD SYSTEM
AS IT MAY PRODUCE UNPREDICTABLE RESULTS.
RECTIFIER CONFIGURATION
Rectier Type – This selects the type of rectier installed in the system from the
drop-down list. In the X75 this is factory preset to RPCM/P and SHOULD NOT
BE CHANGED.
Minimum Rectiers – Enter the minimum number of rectiers that is required to
provide sufcient current to the load and to simultaneously re-charge the batteries
from a fully discharged state in the desired time according to the specication of the
batteries being employed with the system.
CURRENT LIMIT
Select the appropriate button for ENABLE or DISABLE as required.
Battery Charge Limit – When enabled enter the maximum desired battery charge
current.
Using this setting the X75 will intelligently control the rectier oat voltage such
that the battery charge current never exceeds the set value.
