Displaying the Control Board Revision Level
During machine service, it may be helpful to know the control board revision level to determine machine
configuration. To view the control board revision level:
EcoFlex Models:
1. Turn the key switch to the off position.
2. While holding the Scrub Off
(H)
and Chemical
(F)
switches depressed, turn on the key
switch.
3. Hold both switches until Scrub Off and Chemical indicators turn green.
4. The display will show the revision level (letter) of the control unit. Chemical indicator
will blink in revision display mode.
5. To exit this mode, turn the main power key switch to the off position.
Standard models:
1. Turn the key switch to the off position.
2. While holding the Solution
(B)
and Vacuum
(C)
switches depressed, turn on the key
switch.
3. Hold both switches until Solution and Vacuum indicators turn green.
4. The LED display will show the revision level (letter) of the controller software.
5. To exit the revision level recall mode, turn the key switch to the off position.
Recall of Stored Error Codes
To assist with service troubleshooting, the controller maintains a list of past error codes. To recall and/or clear the
stored error codes perform the following steps:
1. Turn the key switch to the off position.
2. While holding the Solution Switch
(B)
depressed, turn the key switch to the on position.
3. Continue to hold the solution switch until the solution indicator turns green.
• On EcoFlex models:
◦ If there are no error codes stored, the display will show the key switch icon.
◦ If any error codes are stored, the display will show the wrench icon and error number right next to the
wrench. If more than one error code is stored, it will cycle through all the error codes stored.
• On standard models:
◦ If there are no error codes stored, the display will show “—”.
◦
If any error codes are stored, the scrub off indicator will be red and the display will show the error
code number(s). If more than one error code is stored, the display will scroll through the error codes in
sequence.
4.
To clear the stored codes, press the scrub off switch. (It is recommended that error codes are cleared after
servicing so that future error codes represent only errors that occur between service intervals.)
• On EcoFlex models, the display will now show the key switch icon.
• On standard models, the display will now show “—”.
5. To exit the error code recall mode, turn the key switch to the off position.
