Troubleshooting
1. Check the liquid level in the cleaning solution bottle.
2. Ensure that the cleaning solution tubing is fully inserted and touches the bottom of the
cleaning solution bottle.
3. Prime the cleaning solution and look to see if back flow occurs at the place where the
cleaning solution tubing is connected to port 1 of the electronic rotary valve (ERV); if
back flow is observed, the tubing connection needs to be tightened.
4. After all the above steps have been checked and the problem is solved, rerun the
analysis procedure to see if the alarm has been eliminated. If the alarm still occurs,
please contact the service personnel to confirm the fault and repair it.
1. Check the liquid level in the standard 2 sample bottle.
2. Ensure that the standard 2 sample tubing is fully inserted and touches the bottom of
the standard 2 sample bottle.
3. Prime the standard 2 solution and look to see if back flow occurs at the place where
the standard 2 solution tubing is connected to port 2 of the electronic rotary valve
(ERV); if back flow is observed, the tubing connection needs to be tightened.
4. After all the above steps have been checked and the problem is solved, rerun the
analysis procedure to see if the alarm has been eliminated. If the alarm still occurs,
please contact the service personnel to confirm the alarm and repair it.
1. Check the liquid level in the standard 1 sample bottle.
2. Ensure that the standard 1 sample tubing is fully inserted and touches the bottom of
the standard 1 sample bottle.
3. Prime the standard 1 solution and look to see if back flow occurs at the place where
the standard 1 solution tubing is connected to port 3 of the electronic rotary valve
(ERV); if back flow is observed, the tubing connection needs to be tightened.
4. After all the above steps have been checked and the problem is solved, rerun the
analysis procedure to see if the alarm has been eliminated. If the alarm still occurs,
please contact the service personnel to confirm the alarm and repair it.
1. Check whether the flow cell is full of water sample, and if there is a lack of water sample,
check the external sample injection flow path.
2. Check whether the connection between sampling tube and flow cell is loose.
3. Check whether the connection of three-way valve to sampling tube and the port 4 and
9 of the electronic rotary valve (ERV) is loose, and whether there is any leakage; if so,
tighten this connection terminal.
4. After all the above steps have been checked and the problem is solved, rerun the
analysis procedure to see if the alarm has been eliminated. If the alarm still occurs,
please contact the service personnel to confirm the alarm and repair it.
