Grc40gh does not generate chlorine

Facts 1) Aquarite does not display any errors led 2) Aquarite diags show cell volt=3.6 but cell current=0.00, sw r1.40, standard display=3.8 (also 8th push, there is 9th push as per Aquarite manual)

My goldline cell reads check cell, what does that mean?

It means you need to clean/replace your salt cell. You can go to your local pool store to get a cell cleaner. Clean the cell, then let the system adjust overnight, and check the controller again in 24 hours. If it still says check cell, it should be replaced.

A phototransistor 4N25 will not adjust below 33.6 volts, what could be the problem?

we can not at all imagine what circuit you have .
post the schematic and this is then child's play.
here is a start, now show what you connected to this device.
ive uses these back to the days of first invented, I love them.
The isolation is very nice,
now the theory, if you understand it , you can make it work.
the current must flow that diode LED, when it does.
the min, current is clearly stated in the data sheet.
diode current at 10ma nets 1/2 turned on,
the transistor in sided, turns on. fully at 60ma.(depends on load)
my guess is the 33.6v, is collector =voltage and not current?
if yes< then the inside LED current is too small.
or your RL resistor is too small.
tell me the collector load resistor and the supply voltage.?
then the LED current. and now we have facts to do the analysis.
good luck.

Aqualink Chlorine Generator not producing any chlorine

It shounds like that you might have a mustard algae issue. It feeds on chlorine. It is possible that your unit is producing chlorine but the algae is consuming it as fast as it can be made. You will need to do a shock treatment and use an Algae 30. It could be something else, but this is likely. You can google mustard algate treatments and read up on it to see if you have other symptoms.

No Power

Good Day;

Shutdown at Power Causes: Cause #1 This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. SELF- DIAGNOSIS INDICATE X-RAY. CHECK FOR A SHORTED IC5A03 PART # 270P704010 AND AN OPEN R5A73 82K ¼ WATT OFF PIN 2 OF IC5A02 ON THE MAIN PCB. 2. SELF DIAGNOSIS ERROR INDICATES SHORT PROTECT. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. 3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB. Good Luck, big IRISH.

161 fatal error C7300

Try this - WARNING - will reset everything to factory defaults

The machine must be put back into "Shipping Mode" in order for the consumable counters to reset.

In order to place the printer back in "Shipping Mode" do the following:


1. For the C72/74/92/94 models, hold the (1) and (5) keys down, for the C73/75/93/95 hold (0), (1), (6), and (7), while turning the printer power on. (Hold until "MAINTENANCE MODE" is displayed)

2. Press (0) five times until "ENGINE DIAG MODE XX.XX" is displayed.

3. Press the (2) and (4) keys simutaneously, "ENGINE DIAG LEVEL 3" should now be displayed.

4. Press the (5) key once, "LOCAL PARAMETER SET" should now appear on the display.

5. Press the (6) key three times until "FACTORY WORKING MODE" is displayed.

6. Once "FACTORY WORKING MODE" is displayed, press (3) once so "Shipping Mode" (Fuse Cut Enabled) is displayed in the bottom line.

7. Next press and hold (3) & (7) together, until "Shipping Mode" stops flashing.

8. Power the printer off and back on, now the printer will reset the consumable counters. ecblank.gif ecblank.gif ecblank.gif
