Chapter 2 Features and Specifications
2.1 General functions
(1) Extended fault detection and protection. The LED flashing pattern indicates the fault
sources. Customers can read the error message in PC software or Android APP also.
(2) Monitoring battery voltage. It will stop driving if the battery voltage is too high and it will
progressively cut back motor drive power as battery voltage drops until it cuts out
altogether at the preset
“Low Battery Voltage” setting.
(3) Built-in current loop and over current protection.
(4) Configurable motor temperature protection range.
(5) Current cutback at low temperature and high temperature to protect battery and controller.
The current begins to ramp down at 90
℃
case temperature, shutting down at 100
℃
.
(6) The controller keeps monitoring battery recharging voltage during regen braking.
(7) Maximum reverse speed and forward speed can be configured between 20% and 100%
respectively and separately.
(8) A 4pin connector to RS232 port and a Z-TEK USB to RS232 cable allows for configuration,
programming and software upgrades using the tablet which must be based on Android OS
now. People can do the same things on PC software by using a standard USB to RS232
cable instead.
(9) Provision of a +5 volt and +12 volt output to supply various kinds of hall sensors.
(10) 5 switch inputs which are activated by connection to 12V. Default to throttle switch, brake
switch, reversing switch, forward switch and Boost switch.
(11) 3 analog 0-5V inputs that default to throttle input, Brake analog input and motor
temperature input
(12) Copy signal of one of hall sensors.
(13) Configurable boost switch. Enables the maximum output power achievable if the switch is
turned on. The effect is the same as full throttle position even if you don
‟t turn throttle at all.
(14) 12V brake switch input used different port from motor temperature sensor.You can use
both brake switch and motor temperature sensor functions at the same time on the latest
version. Pin 25 is 12V brake switch input port.Pin1 is motor temperature sensor input port.
(15) Optional joystick throttle. A bi-symmetrical 0-5V signal for both forward and reversing.
(16) Configurable motor over-temperature detection and protection with the recommended
thermistor KTY84-130/150 or KTY83-122.
(17) 3 hall position sensor inputs. Open collector, pull up provided.
(18) Brake analog regen mode. This regen mode doesn't need brake switch to support any
more on KLS controller. Only available from software version 0106 or advanced version.
(19) Enhanced regen brake function. A novel ABS technique provides powerful and smooth
regen. The regen can happen at any speeds until zero speed.
(20) Cruise control. Only can be activated in forward direction.
(21) Bluetooth function. Required a small Bluetooth converter which needs to be purchased in
addition from our website. This small converter is only useful for KLS controller.
