Troubleshooting
1. Check whether AC 220 power supply output is in good condition.
2. Check whether the 10A fuse at power switch is broken.
Check water source change-over, pressurizing/pressure relief shift is in good
position;
• when water source shift is in tap water position, the pressurizing/pressure relief
shift should be in relief position;
• when water source shift is in distilled water position, the pressurizing/pressure
relief shift should be in pressurizing position.
Troubleshooting
Check whether there is AC 24V voltage input at J6 port of chair control board.
1. If there is AC 24 V voltage input at J6 port, check whether the two yellow keys
can operate to achieve ascent/descent of chair;
if not, the control board is likely to have damaged, replace the control board
to remove the problem.
2. If there is not AC 24V voltage input at J6 port, check whether the chair power
supply plug on flat cable is in good connection;
if not, tighten the screw.
3. If there is AC 24V voltage input at J6 port, check whether the two yellow keys
can operate to achieve ascent/descent of chair; if not, check whether spittoon
protection switch is triggered by using the following method:
Toggle the switch to the left to close it, and the chair can ascend or descend;
toggle the switch to the right to open it, and the chair cannot ascend or
descend.
In case that operating chair ascend or descend automatically,
perform troubleshooting from the following aspects:
1. Assistant Section Touch Control Board:
The assistant section control board may be corroded due to damp absorption
or entry of water, and thereby cause malfunction of the function keys.
Inspection method:
Disconnect the communication cable terminal on the control board, operate
the machine by using pedal and treatment platform to check whether the
failure continues;
if the failure is removed, it indicates that the control board is damaged, and
replace it;
if the failure continues, re-connect the communication cable terminal, and go
to the next step.
2. Treatment platform touch control board:
The treatment platform control board may be corroded due to damp absorp-
tion or entry of water, and thereby cause malfunction of the function keys.
Inspection method:
Disconnect the communication cable terminal on the control board, operate
the machine by using pedal and treatment platform to check whether the
failure continues;
if the failure is removed, it indicates that the control board is damaged, and
replace it to remove the problem.
Inspections:
1. If water heater fails, check whether there is AC 23 V voltage output at J13;
if yes, the heater may be broken and replace it;
if no, the side case control board or the heater is damaged;
if heater cannot be disconnected, and J14 is always closed, the heater may
be broken and replace it.
2. If there is no voltage output at J13, check whether fuse F4 is broken;
if yes, replace it with a 6A fuse.
