I have a dolphin cleaner that is not working. The power supply voltage drops from 37 VDC to about 4 VDC when the cleaner is plugged in. It previously had a severed power cable that was repaired. I saw a charred 2 watt resistor on the power supply circuit board that I replaced with a 0.1 resistor, but it still drops the voltage when the cleaner is plugged in. Thoughts? Cleaner or power supply? Schematic available? Thank you,

• Code: 001 S96
• Description:Power supply remote signal not connected The control signal cable for the ON/OFF control of the 24/38-VDC output is disconnected. The signal wire grounded inside the power supply unit has been pulled up by the IP PCB to detect the level.

• Code: 003 S97
• Description:38-VDC power supply voltage error A voltage drop is detected when a voltage drop is sensed by the IP PCB based on the signal resulting from dividing the 38-VDC resistance inside the power supply unit. The detection level is approximately 18 VDC. Voltage polling is conducted at 100-ms intervals by the IP-CPU. An error is detected when a voltage drop is sensed 10 times in succession (approx. 1 sec). No detection is performed when the interlock SW is open.

• Code: 004 S97
• Description:24-VDC power supply voltage error A voltage drop is detected when a voltage drop is sensed by the IP PCB based on the signal resulting from dividing the 24-VDC resistance inside the power supply unit. The detection level is approximately 11 VDC. Voltage polling is conducted at 100-ms intervals by the IP-CPU. An error is detected when a voltage drop is sensed 10 times in succession (approx. 1 sec). No detection is performed when the interlock SW is open.

• Code: 006 S97
• Description:3.3-VDC power supply voltage error A voltage drop is detected when a voltage drop is sensed in the 3.3-VDC power supply on the MIP side of the IP PCB. Voltage polling is conducted at 100-ms intervals by the IP-CPU. An error is detected when a voltage drop is sensed 10 times in succession (approx. 1 sec).

• Code: 007 S97
• Description:1.8-VDC power supply voltage error A voltage drop is detected when a voltage drop is sensed in the 1.8-VDC power supply on the MIP side of the IP PCB. Voltage polling is conducted at 100-ms intervals by the IP-CPU. An error is detected when a voltage drop is sensed 10 times in succession (approx. 1 sec).

• Code: 008 S96
• Description:Control panel not connected The absence of the control panel unit to be connected to the MC PCB is detected. Since this configuration lacks this panel, this error indication will not be issued under normal operating circumstances.

• Code: 009 S96
• Description:Print counter not connected The absence of a print counter is detected.

• Code: 011 S96
• Description:CIS PCB not connected The connection of the CIS PCB cannot be confirmed.

/PSON activated by pressing and releasing the power button while the power supply is in standby mode. Activating /PSON connects the power supply's /PSON input to ground, thereby switching the power supply to full-on condition.
18 AWG is recommended for all wires except pin 11, which should be 22 AWG. For 300W configurations 16 AWG is recommended.
There are several ATX variants.
Hope this helps.
If this helps you resolve your problem, please
consider giving me a rating of 4.It will help me as well. Thank you.

When you have this problem on this PC, do not replace the power supply or the motherboard until you have first tried pulling out the video card. When the video card fails it can cause the x1700 to not power up. Pull the video card and see if it will power up without it.

For warranty and non-warranty repair service contact us using the dolphin service form at www.arrowpools.net or you can try the manufacturer at www.maytronicsus.com.

You'll need a replacement board. You'll need model and serial numbers off of the cleaner itslef to help identify which power supply and therefore what PCB is needed to replace yours. Try contacting our service center at www.arrowmotor.net and click the contact button in the upper right corner.
