For example, if temperature sensor is SGH (120°C resistor type), its sensor curve is SGH (120°C resistor type); if select the SGD (120°C resistor type), the temperature sensor curve is SGD curve. b) When there is difference between standard sensor curves and using sensor, user can adjust it in "curve type" and input target curvilinear coordinate. c) When input the sensor curve, X value (resistor) must be input from small to large, otherwise, mistake occurs. d) The headmost or backmost values in the vertical coordinates can be set as same as below. e) For current type sensor, sensor curve is linear, and it only needs to set the coordinate of two points.

Negative of battery must be connected with the shell of engine. The wire's diameter of battery negative and positive, which is connected to B+ and B- of controller power must be over 2.5mm2. If floating charger configured, please firstly connect output wires of charger to battery's positive and negative directly, then, connect wires from battery's positive and negative individually to controller's positive and negative input ports in order to prevent charger disturbing the controller's normal working. a) Output And Expand Relays All outputs of controller are relay contact output type. If it needs to expand the relays, please add freewheel diode to both ends of expand relay's coils (when coils of relay have DC current) or, increase resistance-capacitance return circuit (when coils of relay have AC current), in order to prevent disturbance to controller or other's equipment. b) Withstand Voltage Test When controller had been installed in control panel, if it needs the high voltage test, please disconnect controller's all terminal connections, in order to prevent high voltage into controller and damage it.
