Nicd/ Nimh Battery Charge Setup; Pb Battery Charge Setup - GRAUPNER POLARON PRO Operating Manual

Cut-off temperature. Detected using an optional temperature sensor, a safety cut-off
CUT-TEMP temperature can be set to automatically terminate charging or discharging processes. This
termination can occur for battery temperatures exceeding a preset value.
The maximum capacity setting is used to terminate a charge. The maximum capacity is
MAX CAPACITY used to prevent the battery capacity from exceeding a preset percentage. Damaged, poorly
balanced, or improperly programmed batteries can be overcharged without this limitation.
The safety timer can be used to terminate a charge for charging times that exceed
SAFETY TIMER
this preset time period. This timer can be used to protect the battery from damage.
The battery voltage in the store mode. This parameter is used to terminate a charge
STORE VOLT
for voltages that reach a preset voltage value.
13.2 NiCd/ NiMH battery charge setup (Applied to CH1 and CH2)
Charge current. - Tapping the INC/DEC buttons can activate and edit this parameter. The default
charge current is set to 1C (1 x capacity). The CH1 could be configured from 0.1A to 20A (to be
CURRENT
operated within 500W) and CH2 could be configured from 0.1A to 3.0A (to be operated within
30W).
Delta-peak cut-off voltage. - This parameter is used to charge the NiCd/ NiMH batteries. As the
pack voltage peaks, the pack becomes hot and the pack voltage drops off. This charger
PEAK SENS
terminates the charging process using a Delta-peak cut-off. The default parameter is 3mV/cell for
the NiMH batteries and 7mV/cell for the NiCd batteries.
Trickle charge current. - With NiCd and NiMH type batteries, a trickle charge process is recommen-
ded after the main charge has completed, allowing the battery to become fully charged and ready
TRICKLE
to be used. The recommended trickle charge current is approximately 10% of the pack capacity
(possible to set to a max of 500mA).
Cut-off temperature. - Used with an optional temperature sensor, a safety cut-off temperature value
CUT-TEMP can be specified, allowing the charging or discharging processes to automatically terminate for
battery temperatures exceeding a preset value.
The maximum capacity setting is used to terminate charging processes for battery capacities
MAX CAPACITY exceeding the selected percentage values. Damaged or improperly programmed batteries can be
overcharged without a proper setting of this parameter.
The safety timer can be used to terminate the charging process for charging times that exceed
SAFETY TIMER
a preset time period. This timer is used to protect the batteries.
13.3 Pb battery charge setup (applied to CH1)
VOLTAGE Maximum cell voltage. - CV (Constant Voltage)
Charge current. - Tapping the INC/DEC buttons can activate and edit the parameters. The default
CURRENT charge current is set to 1C (1 x capacity). This value can be adjusted from 0.1 to 20 Amps,
operating within the 500W limitation.
Cut-off temperature. - Used with an optional temperature sensor, a safety cut-off temperature can
CUT-TEMP be set, allowing the charging or discharging processes to automatically terminate at battery
temperatures exceeding the preset temperature valu.
The maximum capacity setting is used to terminate charging processes that result in battery
MAX CAPACITY capacities exceeding a preset percentage value. Damaged, poorly balanced, or improperly
programmed batteries can be overcharged without this limitation.
The safety timer can be used to terminate the charging process for charging times that exceed
SAFETY TIMER
a preset time period. This timer is used to protect the batteries.
The programmed data are stored in the memory and used to charge the batteries. Tapping the Enter button initiates
the charging process. The balance connector verification, the charge mode verification, the number of cells to be
charged, and the delay time setup should be finished prior to the charging process.
For an improperly programmed setup, the charger will initiate a 5-second countdown without many external controls.
