Sunray instruments are all-digital instruments which take stepping motors as the structural forms. Analog or
digital signals of all sensors are converted into digital signals via processing of central processing units (CPU) to
drive the stepping motors. After the processing, the drive signals are sent to respective indicating instruments of
stepping motors and actuate their operations.

All-digital instruments are adopted in Sunray series, which do not only eliminate disadvantages of conventional
analog display instruments, but also possess following advantages:

1.

The indication accuracy may reach 1/12°as the
highest.

2.

It enables the stable indication without the
application of damping oil and pointer balancer.

3.

It enables easy installation and debugging without
any hysteresis errors that the instrument possesses
good reliability, good consistency and strong
vibration resistance.

4.

It enables long service life and wide operating
range of -40°~+85°.

5.

It enables low voltage (5V) and low current drive,
all-digital control and low consumption.

6.

It enables strong anti-interference.

7.

It enables smaller thickness and weight of the
instrument.

8.

LED is applied as indicator lamps and backlights
which enables lower power consumption, longer
service life and lower heat. And LED backlight
technology is adopted for homogeneous and soft
lighting.

9.

LCD is applied for mileage display and mileage
subtotal to avoid stuck phenomenon with the
application of gear display and it is easily installed
and debugged.

10. SMD parts and reflow soldering technology may

prevent the instrument from faults caused by
insufficient solder and void and enable lower
weight of the instrument.

11. Software warning is adopted in fuel warning and

the fuel warning switch in the sensor can be
revocatory.

12. With proper modifications of instrument software

parameters, the instrument can be applicable to
vehicles with different gear ratios, speeds, fuels and
temperature sensors and the applicable range is
very wide.
