Probe Mode Adjustment Menu Settings (Program Menu 3)
Program Menu 3 is considered the Adjustment Menu for Probe Mode. It is accessible by entering the proper Program Mode
password and pressing the Scroll key at the blinking "2" of the Program Menu 2 to move to Menu 3.
NOTE: Which adjustment menu appears, when pressing the Scroll key at the blinking "2" of the Program Menu 2, depends
on the setting of Menu 21. If the Detergent Control is set to "1" for Probe Mode, then Menu 3 appears. If the Detergent
Control is set to "2" for Probeless Mode, then Menu 4 appears.
Below are details for the individual adjustment settings available in Program Menu 3, as shown in the menu tree on page 21.
Menu 31: Detergent Tank Reading
Press the Enter key
at Menu 31 to see a live reading from the Conductivity probe installed in the wash tank.
One use for this display is when establishing the proper Set Point during installation. Prepare for this reading by manually adding
detergent to achieve the proper concentration, confirmed by testing via titration or measured volume. The dishwasher tank
solution must be well mixed (wash pump running) and at operating temperature.
Then use Menu 31 to view the Conductivity reading, which is a running average updated every 0.1 seconds. Make note of the
tank reading displayed and use the value as the Set Point for Detergent Control in Menu 32.1.
Menu 32.1: Detergent Set Point
(default = 4OO)
000 to 999
This is the setting that will initiate Detergent Feed, when the Conductivity reading falls below the value defined here.
Any value 000 to 999 may be used. Press the Scroll key to change the value of the blinking digit. Press the Next key to move
to the next digit.
Press the Enter key
Menu 32.2: Live Conductivity Display
1 = Yes, display Conductivity after User Menu 14.
2 = No, do not display Conductivity in User Menu.
This setting controls whether a live Conductivity reading will be displayed after User Menu 14. If enabled, pressing the Next
key at Menu 14 will show a live Conductivity reading instead of returning to the Idle Home Screen. Also, this display will not
"time out" like most menus which return to the Idle Home Screen after 25 seconds of no key activity.
Menu 33: Rinse Pump Speed
0.0 to 59.5 Revolutions Per Minute (RPM)
NOTE: This setting only effects the dispenser operation when the optional Rinse Pump is installed.
Instead of setting how long the rinse pump runs for each wash cycle, the amount of rinse agent added is adjusted using the
rinse pump speed. Press Scroll to change the value of the blinking digit. Press Next to move to the next digit. Press Enter
key at any time to accept the number displayed as the new setting for the Rinse Pump Speed.
NOTE: Adjust the rinse pump speed to dose an appropriate amount of product needed for good results on wares. To
determine this adjustment, note the amount of rinse product per unit of water (check the dish machine specifications for rinse
water flow rate per minute) or observe the sheeting action of the product on wares. With the standard rinse pump tube, in
new condition, the EvoWash rinse pump will dispense approximately 0.5 ml per revolution.
Testing: With the Rinse Pump Speed displayed, press and hold Next and Enter to run the pump at the displayed speed.
