ELECTRICAL SYSTEM
Vacuum Automatic Shut-off Threshold Adjustment:
FACTORY DEFAULT: 4
The sensitivity of the automatic vacuum shut-off feature can be adjusted if necessary. This adjustment sets the amount of change required in
the vacuum power consumption to cause the control unit to indicate a full recovery tank condition. The setting is adjustable from 0 to 9. 0 is the
minimum sensitivity, 9 is the maximum sensitivity. If the unit falsely indicates a tank full condition, try setting this parameter to a lower value. If the
control unit fails to shut the vacuum system off when the recovery tank fl oat ball plugs the vacuum inlet, try setting this parameter to a higher value.
To adjust the vacuum shut-off sensitivity perform the following steps:
1 Turn
the main power key switch to the off position.
2 Press and hold the maintenance mode and the solution switch.
3 While holding both switches turn the main power key switch to the on position.
4 Continue to hold both switches until the solution indicator is fl ashing yellow.
5 Release both switches. The status display will now indicate a number from 0 to 9 depending on the threshold setting.
6 Pressing and releasing the solution switch will now select the threshold level. The level will increment from 0 to 9. 0 = minimum sensitivity, 9
= maximum sensitivity.
7 To save the new setting, turn the main power key switch to the off position.
8 The new setting will be saved and will remain in effect until it is changed again.
Recall Of Stored Error Codes:
Whenever an electrical system fault is detected by the main control unit, one or more error codes are displayed and stored by the control unit. If it
is desired, the error code (if any) from the previous operation of the machine can be recalled for troubleshooting purposes. To recall the last stored
error codes perform the following steps:
1 Turn
the main power key switch to the off position.
2 Press and hold the solution switch.
3 While holding the solution switch, turn the main power key switch to the on position.
4 Continue to hold the solution switch until the solution indicator is green.
5 Release the solution switch.
6 If there were previously no error codes stored, the display will now show “-”. Go to step 11.
7 If error codes were stored, the display will now show the stored code(s) and the scrub system off indicator will now be red. An example of how
two codes, 6 and 18, would be displayed is as follows:
• The display will show “E” followed by a brief blank period
• The display will show “0” followed by a brief blank period
• The display will show “6” followed by a slightly longer blank period
• The display will show “E” followed by a brief blank period
• The display will show “1” followed by a brief blank period
• The display will show “8” followed by a long blank period
• The above sequence will repeat
8 To pause the display, press and hold the solution switch.
9 To clear the stored codes press and release the scrub system off switch. The display will now show “-“. Go to step 11.
10 If it is desired to save the codes, go to step 11.
11 To exit the error code recall mode, turn the main power key switch to the off position.
