Peak Detect Voltage
Peak Detect Voltage appears on the display as "Peak Det V". This is the dropback
voltage setpoint at which the T35-GFX will automatically terminate the charge operation.
Units are in volts. Turn the ROTARY DIAL SWITCH to set the Peak Detect volts.
TurboFlex On/Off
TurboFlex On/Off appears on the display as "Turboflex". This is the setting that turns the
TurboFlex feature On and Off. Rotating the ROTARY DIAL SWITCH will toggle the
setting.
TurboFlex Level
TurboFlex Level appears on the display as "Turboflex Level". The TurboFlex level
adjusts the discharge rates relative to the charge rate. The discharge rate of the burp is
fixed at 5 amps.
The TurboFlex "burp" takes place once per second.
The duration of the TurboFlex discharge period every second is given by:
(((Charge_Amps*4* Turboflex_Level)+17000)/2)*0.2uSec
So, for a charge rate of 5 amps and a TurboFlex level of 5, the duration of the discharge
burp will be (((5*4*5)+17000)/2)*0.2uSec = 1.71 mSec.
Long Lockout On/Off
Long Lockout appears on the display as "Long Lockout". Normally, at the beginning of a
charge cycle, the T35-GFX will disregard dropback voltage from the peak voltage
detected up to the present point in the charge process for a duration of 60 seconds. This
allows stabilization of the pack voltage for a short period before peak detection kicks in.
In order to overcome false peaking, Long Lockout can be activated. This will cause
dropback voltage to be disregarded for 10 minutes, beginning at the start of the charge
cycle.
Long Lockout will be reset to OFF after the cycle ends. This is done to avoid, as much as
is possible, putting current into a fully charged pack for 10 minutes, which is what would
happen if you connected a fully charged pack and Long Lockout was ON. Our
philosophy is that the user needs to deliberately turn on long lockout, and then the user
will not arbitrarily make this mistake.
# of Peaks
The T35-GFX terminates the charge cycle when the peak negative dropback voltage is
equal to the peak detect setting. Sometimes, the racer might want to repeak the cell or
pack after the primary charging is finished. Setting the "# of peaks" to 2 will enable an
entire second charge and peak detect.
The settings for this second peak are found on the "peak 2" page in the charge mode. This
includes charge rate (independent from the first peak charge rate), peak detect volts,
turboflex, and delay.
