5.O3 GUIDED SETUP - Probeless Mode (continued)

Probeless Mode on an Alternate (Alt) Door Machine

An Alternate Door Machine is a Door Machine that has two

independent solenoids for the fill and for the rinse process.

This means that there is no rinse signal active when the

system is filling, therefore the logic for dosing detergent initial

charges is different for an Alternate Door.

To configure a DMx unit that utilizes Probeless/Time mode on

an Alternate (Alt) Door Machine, start on the Guided Setup

Screen.

Confirm that the gray button is set to Probeless and select Alt

Door as the Machine Type.

When complete, press Next to continue setting up the dosing

parameters for Detergent and Rinse.

Detergent

Detergent settings for Probeless Mode on an Alternate (Alt)

Door Machine require the following fields to be set:

Initial Charge (0-200s): An initial charge is meant to be

dispensed every time the tank is drained and refilled with fresh

water. In Probeless, Alternate (Alt) Door Mode, it is triggered

when the detergent signal is received and stays on for 10

seconds. The detergent signal in this case should be wired

to a signal that is on once per drain/fill cycle such as an “on

light,” the on/off switch on the dish machine, or if present, or

an electrical tank heat circuit between the tank heater switch

and the thermostat. If the dish machine does not have the

appropriate signals, please contact Hydro Technical Support.

Incremental Dose (0-20s): An incremental dose is dispensed

in Probeless, Alt Door Mode after racks complete and are

counted (per the Rinse signal cycling on/off). The incremental

dose will dispense for the time setting, and the pump will stop.

To trigger another incremental dose, the proper number of

racks must be completed.

Dose Interval (Every 1-3 Racks): In some cases on

Alternate Door machine, the user may not want to inject

detergent on every rack. If that is the case, the Dose Interval

can be increased to dispense every 2 or 3 racks instead.
