6000 & 7000 Series DISHWASHERS
4.10.4 TURBIDITY INPUT OPERATION
Models 6400/6500, 6600, 6700/6900, 7000 Series.
Note: There is no turbidity sensor on the 6605 and 6905 models.
During the Relay/Triac output test (Refer 4.10.1) the SENSING LED, (POTS & PANS LED on 7000 series), (or the WASH
CYCLES LED on Rotary machines, provided Turbidity Sensor monitoring was selected), will indicate if the turbidity sensor is
operating correctly.
The LED is to illuminate only when the turbidity sensor is outputting both, a valid turbidity frequency, and a valid temperature
signal, to the controller.
4.10.5 RINSE AID SWITCH INPUT OPERATION
Models 6400/6500, 6600, 6605, 6700/6900, 6905, 7000 Series.
During the Relay/Triac output test (Refer 4.10.1) the WASHING LED, (NORMAL WASH LED on 7000 series), (or the WASH
CYCLES LED on Rotary machines, provided Rinse Aid Level Switch monitoring was selected), will function as a Rinse Aid
Level Switch status indicator.
The LED is to illuminate only when the low rinse aid level reed switch is closed.
