Note on function #3, undervoltage recognition:
If recognition of the cell number is set to "Automatic" as in function #2, this is automatically calculated according to
the battery voltage after activation of the speed controller. However, the rechargeable battery must be fully charged
for this. The automatic recognition (or manual setting) of the cell number is used to calculated the corresponding
undervoltage threshold.
An undervoltage recognition is not recommended when using NiCd or NiMH batteries. Therefore, pro-
gramme to "off".
Deep discharge will destroy LiPo batteries. We therefore urgently recommend activating an undervoltage recogni
-
tion for use of LiPo batteries. You may set the following values: 2.8 V/cell, 3.0 V/cell, 3.2 V/cell (recommended) and
3.4 V/cell.
The undervoltage recognition will switch off the motor during operation and with the battery empty (e.g. when
3.2 V/cell is set and a 6-cell battery is used with a battery voltage of approx. 19.2 V). In this case, the red LED at the
speed controller will flash at a slow rhythm.
If you notice a sudden stop of the motor after extended operation, the undervoltage recognition has recognised a
nearly empty battery. A motor that has been limited like this can be activated again by briefly putting the lever for the
driving function in the neutral position at the transmitter. The motor will now turn at reduce power only. In this case,
drive to the banks immediately and terminate operation. Otherwise, the drive battery is further discharged, which will
cause damage to the drive battery.
Notes on function #4: Motor Timing
This setting influences motor running characteristics (similar to early ignition of a combustion engine). The following
options are available:
0° to 11.25° = low timing
15° to 18.25° = normal timing
22.5° to 26.25° = high timing
Setting a low timing value means that the motor has a little more torque as compared to the basic settings, and a
little lower maximum speed. Setting a high timing value means that the motor has a little higher maximum speed as
compared to the basic settings, and a little less torque. In both cases, the current values change however. Therefore,
also observe compliance with the motor and speed controller specifications. Also observe the temperatures of the
components named in operation.
For this reason, we recommend that the factory settings not be changed.
