Curtis 1030 Acuity Manual, Rev. C
7 — DEVICE PARAMETER OBJECTS
Battery Cycle Low and High Thresholds (BC_LTh, BC_HTh) (510Ah) Battery discharge
cycles in any application are irregular. BC_LTh and BC_HTh set thresholds
to define a battery cycle. The Acuity increments the battery cycle if the
battery’s SoC drops below BC_LTh and then rises about BC_HTh.
Historical Record Store Interval (HRint) (510Bh) This parameter defines the fraction
of the rated capacity (discharged or charged) at which the historical record
is stored. Historical record storage can be set at 1/8th, 1/16th, 1/24th, or
1/32nd of rated capacity C.
Conguring parameters
The Device Parameter Objects can be used to configure the Acuity parameters
for the application battery.
Most configurable parameters require a keyword to be sent along with
the value to be changed. Keywords consist of one or more ASCII characters.
Letters are case sensitive. To permanently store configurable parameters into
non-volatile memory, a Store command (keyword STOR) needs to be sent.
The timeout between setting the parameters and sending the Store command
is 15 seconds.
