Rotary valve failure (E3)
1.Visually check the electrical parts (rotary valve control board and serial
port communication adapter board) at the rear of the electronic rotary
valve for obvious corrosion. If there is any corrosion, it is necessary to
power off, replace relevant parts and try again;
2.Visually inspect each connecting tubeline of rotary valve for blockage or
crystal residue, if any, clean up the tubelines, or replace relevant
tubelines;
3.Operate the rotary valve with the system diagnostic function of the
instrument, and check whether the feedback position of the rotary valve
is correct;
4.Disconnect the power supply of the instrument, power on it again, and
check whether the electronic rotary valve works normally. If the fault still
occurs, contact the after-sales personnel to confirm the fault and repair
it.

Injection pump failure (E2)
1.Visually check whether the three-way valve and syringe pump of the
injection pump are normal;
2.Check whether the electrical connection of injection pump is reliable;
whether there is obvious corrosion on the electrical parts, if there is any
corrosion, it is necessary to power off, replace relevant parts and try
again;
3.Cut off the power supply and manually push the big black sliding block
under the syringe pump to see if it can move up and down smoothly. If
not, remove the syringe pump and try again. If it can move up and
down smoothly, the syringe pump needs to be replaced or cleaned
(note that the black flat gasket should not fall off and must be installed
back, otherwise serious leakage may occur); if it still fails, the injection
pump needs to be replaced;
4.Restart the machine and check whether the injection pump is working
properly by using the diagnostic function of the instrument; if the fault
still occurs, contact the after-sales personnel to confirm the fault and
repair it.
24
Three-way valve failure (E4)
1.Visually inspect each connecting tubeline of three-way valve for
blockage or crystal residue, if any, clean up the tubelines, or replace
relevant tubelines;
2.Operate the three-way valve with the system diagnostic function of the
instrument, and the three-way valve will give out a loud switching sound
when it works normally;
3.Cut off the power supply of the instrument, power on it again, and
check whether the electronic rotary valve works normally. If the fault still
occurs, contact the after-sales personnel to confirm the fault and repair
it.
