ALC700 Series Light Tower Set Controller
ALC700 Series Light Tower Set Controller 2018-03-02 Version 1.4 Page 50 of 51
connected to No.34 and No.35 terminals in controller. The output voltage of speed sensor
should be within AC(1~24)V (effective value) during the full speed. AC12V is recommended (in
rated speed). When install the speed sensor, let the sensor is spun to contacting flywheel first,
then, port out 1/3 lap, and lock the nuts of sensor at last.
13.3 OUTPUT AND EXPAND RELAYS
All outputs of controller are relay contact output type. If need to expand the relays, please add
freewheel diode to both ends of expand relay’s coils (when coils of relay has DC current) or,
add resistance-capacitance return circuit (when coils of relay has AC current), in order to
prevent disturbance to controller or others equipment.
13.4 AC INPUT
Current input of ALC700 controller must be connected to outside current transformer. And the
current transformer’s secondary side current must be 5A. At the same time, the phases of
current transformer and input voltage must correct. Otherwise, the current of collecting and
active power maybe not correct.
NOTE
: ICOM port must be connected to negative pole of battery.
WARNING!
Whe
n there is load current, transformer’s secondary side prohibit open
circuit.
13.5 DC CURRENT INPUT
Hall DC sensor must be connected externally to the ALC700 controller and the output value is
4-20mA.
13.6 WITHSTAND VOLTAGE TEST
When controller had been installed in control panel, if need the high voltage test, please
disconnect controller’s all terminal connections, in order to prevent high voltage into controller
and damage it.
