Choose a location to install the rinse injection fitting at least 6” below the dish machine rinse plumbing vacuum breaker to conform to plumbing codes. The injection fitting threads into 1/8” NPT female threads.

If the dish machine rinse plumbing is thin-wall pipe, use a saddle clamp with a 1/8” NPT threaded hole. If an optional pressure switch will be used, thread the injection fitting into one side of the pressure switch water source fitting pipe tee.

2. Check for a tapped hole to accommodate the fitting. A suitable hole must be at least 6” downstream from the solenoid valve and vacuum breaker. On continuous rack, flight, or conveyor machines, be sure this location is downstream from any rinse by-pass water pipe. 3. If no suitable hole exists, drill an 11/32” hole in the rinse plumbing injection location. 4. Tap the hole with a 1/8” NPT tap. 5. Install the injection fitting. Use thread sealant to ensure a leak-free assembly. Detergent Bulkhead Fitting (Liquid Detergent Only) Correct placement of the detergent bulkhead fitting is critical for accurate detergent concentration control (in probe mode only).

1. Choose a mounting location that ensures the detergent bulkhead fitting is: • Above the water line in the tank. • Close to the probe location (when possible). • Discharging detergent directly into the wash tank and not on top of any shelf areas or other obstacles that could prevent detergent from falling directly into the wash tank.

2. Previously punched holes may be suitable, but always confirm that the fitting is correctly placed. 3. If no suitable hole is available, drill a 3/8” hole in the center of the detergent inlet location. Use a Greenlee (or similar) 7/8” hole punch to cut the final hole. 4. Remove the detergent bulkhead fitting retaining nut. 5. From outside the machine, insert the detergent bulkhead fitting (with rubber gasket) into hole. 6.

Connect the brown wire to the other line of the voltage source. Detergent Signal Wiring The detergent signal input is an optically isolated signal input, include in table internal terminal locations that draws no more than 20 mA. It is a universal voltage input that accepts any voltage listed in Table 4-1. Detergent Signal Wiring – Probe Mode Typical wiring locations are dispenser detergent power supply (DPS1 & DPS2) or the wash motor contacts in the dish machine control panel. This power source is on when the dishwasher is running the wash pump. • Connect Yellow (+DC or AC) and Yellow/White (-DC or AC) colored wires to detergent power supply.

Detergent Signal Wiring – Probeless Mode On conveyor type dishwashers, the detergent signal must occur only once per dish machine fill/drain occurrence–beginning when the dish machine fills. Typical wiring locations are an “on light,” an on/off switch if present, or an electrical tank heat circuit between the tank heater switch and the thermostat. Each time this power source comes on and stays on for 10 seconds, the dispenser will feed the detergent initial charge amount. On door-type dishwashers, connect this signal input to the dispenser detergent power supply or the wash motor contacts in the dish machine control panel.

This power source is on when the dishwasher is running the wash pump.

To facilitate Automatic Initial Charge on alternate machines or machines that do not provide a rinse signal during the fill, connect the detergent signal wires to a power source that occurs only once per fill/drain occurrence beginning when the dish machine fills. Typical wiring locations are a main ON/OFF switch or an on light. • Connect Yellow (+DC or AC) and Yellow/White (-DCor AC) colored wires to initial charge power source.

Probe Mode—This mode requires a conductivity probe be mounted in the wash tank to measure detergent concentration.

Detergent is dispensed automatically when measured concentration levels fall below the programmed set point.

2. Probeless Mode—No probe is required. An initial charge of detergent is dispensed when the machine is filled and upon a specified signal from the dishwasher. Detergent dose is dispensed for a fixed programmed time each time. Rinse control and Rack counts are handled differently for each mode as described below. Detergent Control In Probe Operating Mode, the controller begins monitoring the conductivity probe to determine detergent concentration. The detergent feed is activated as soon as the concentration calculated from the conductivity signal has gone below the programmed set point and there is a detergent signal present.

When the set point is reached the detergent feed is de-activated.

The detergent signal from the washer should remain on while the wash tank motor is on, otherwise the detergent feed will not activate. The detergent signal is typically wired to a power source that is on when wash pump is running. Low Detergent Alarm If the conductivity is below the set point and has not increased by 10% within a programmed number of racks, a visible and audible alarm will be activated. The alarm will sound at the end of each rack until the conductivity rises by 10%. If the conductivity has not increased by 10% for twice the preset number of racks, an alarm will be activated and the detergent feed will stop.

Operator intervention is required to restart the detergent feed.

P/N 10096880 REV A © Hydro Systems Company, Inc. 2014 HydroSystemsCo.com Toll Free: 1.800.543.7184 13 Rinse Control In Probe Operating Mode, rinse signal input controls the rinse output. When the rinse signal is present, the rinse pump will run at the programmed speed until the rinse signal goes off. This varies depending on the selected rinse feed option for door machines.

Conveyor Machines Rack Counts For conveyor machines, conveyor time is defined as the time it takes to move one rack length. A programmed conveyor time setting is used to count the number of racks on a conveyor machine. A rack is counted when the rinse on time equals the programmed conveyor time.

Tank Change Interval To signal an alarm when it is time to change the tank water, a tank change interval can be used in conjunction with number of racks run since the initial charge. (In Probe Mode, this will require a separate initial fill signal to determine the initial charge.) Rinse Pump Rinse Saver is not a feature of conveyor machines. Instead, the rinse pump will run continuously as long as the rinse signal is active. However, the rinse pump will only operate if a detergent signal has occurred within the previous 90 seconds.

Door Machines Rack Counts For door machines, a rack count will be registered each time the rinse signal toggles from Off to On.

Tank Change Interval To signal an alarm when it is time to change the tank water, a tank change interval can be used in conjunction with number of racks run since the initial fill. Rinse Delay Time A rinse delay of 0-19 seconds can be programmed for door machines. The rinse delay will occur at the beginning of each rinse signal input. Rinse Saver The pump will only be allowed to operate continuously for a maximum of 20 seconds. After 20 seconds, the rinse signal input must toggle Off and back On again. Please note, this will also cause the rack count to be incremented The Rinse Pump will only operate if a detergent signal has occurred within the previous 90 seconds.

Rinse Feed Option There are two options for the Rinse Pump to activate. Option 1 (Rinse on Rinse) will run the Rinse Pump each time the Rinse Signal activates (for the duration of time the signal is present). Option 2 (Rinse on Det) will run the rinse pump for a fixed time of 12 seconds each time the Detergent Signal activates. Please note, the Detergent Signal must be toggled On/Off for the rinse pump to run again. With each toggle, the rack count will be incremented.

Pulse Feed Pulse Feed is used only with capsule-type detergent in Probe Operating Mode. If the conductivity reading is within the set point by a user-specified percentage, the detergent feed will be cycled On and Off (pulsed) at a user-selected frequency. Otherwise, the detergent feed will be on continuously. This allows the controller to gradually reach the set point without overshooting. If it is turned on, the user must choose between one of seven different fixed options for frequency and percentage with the set point. (For example, if the reading is within 80% of the set point, the default option is 2 seconds on, 6 seconds off.

Operating Modes: Probe Operation Mode

P/N 10096880 REV A © Hydro Systems Company, Inc. 2014 HydroSystemsCo.com Toll Free: 1.800.543.7184 14 Initial Charge Door Machines Whenever the dispenser receives a rinse signal that was not preceded by a detergent signal within 90 seconds prior (as in an initial fill), an automatic initial charge occurs. The automatic initial charge consists of disabling the rinse feed and feeding detergent for the preset amount of time programmed for detergent initial charge. Normal rinse signal activations within 90 seconds after a detergent signal will not trigger an initial charge.

A five minute lockout timer begins at the start of the initial charge to prevent additional triggering if multiple rinse signals are detected during fill.

Alternate Door Machines An Automatic Initial Charge in a Alternate Door machine occurs each time the dispenser receives a detergent signal input (with 2 second qualification). The detergent feeds for the programmed time for initial charge. Conveyor Machines Each time the dispenser in a conveyor machine receives a detergent signal input (with 3 second qualification) that remains on for 10 seconds continuously, an automatic initial charge occurs. The detergent feeds for the programmed time for detergent initial charge.

The rinse pump is locked out during the detergent initial charge if the rinse signal was previously on. When the initial charge is complete, the rinse pump will not turn back on until the rinse signal is toggled Off to On. Because the initial charge will occur each time a detergent signal occurs, the source of the detergent signal must remain on for the duration of time the tank is full, or must not occur more than one time per machine fill. If the detergent signal is toggled and qualified for 3 seconds, then continuously on for 10 seconds, the dispenser will receive another signal. If this happens before the initial charge completes, it will run the detergent for another initial charge cycle.

The initial charge will run the full charge time regardless if the detergent signal is turned off prior to completion. On a conveyor machine, the detergent signal is typically wired to an “on light” or an electrical tank heat on/off switch. Each time the power source comes on, the dispenser feeds the detergent initial charge amount. If Manual Initial Charge is selected, there is no automatic initial charge. Detergent Dose Door Machines When the detergent signal on a door machine is activated with (3 second qualification) a detergent dose of a programmed time will occur once per programmed detergent dose rack interval.

The rinse signal must then activate to run the rinse pump before detergent can run again.

Door Machines with No Rinse Signal on Fill (Alternate Door machines) If a door machine has no rinse signal upon fill, select this option. In an Alternate Door Type dishwasher Detergent is dispensed when the Rinse Signal is activated based on the detergent dose interval and detergent dose time. Conveyor Machines On a conveyor machine, a detergent dose of a programmed time will occur when the accumulated Rinse On signal time reaches the conveyor rack time multiplied by a programmed detergent dose interval (1, 2, or 3 racks). The rinse signal does not need to be toggled off and on for another dose to occur.

Operating Modes: Probeless Operation Mode

P/N 10096880 REV A © Hydro Systems Company, Inc. 2014 HydroSystemsCo.com Toll Free: 1.800.543.7184 15 Low Detergent Alarm Threshold A low detergent alarm is available for Probeless Operating Mode if a conductivity probe is installed in the same manner as for Probe Operating Mode. When the probe is connected, it senses detergent conductivity at 20 different preset threshold values (0-19). Each setting is equivalent to a calibrated conductivity value divided by 10 (i.e., the default setting of 5 is equal to a conductivity setting of 50). If the conductivity goes below the setting and remains there without rising at least 10% for a programmed number of racks, a visible and audible alarm will be activated.

The alarms will remain on until the conductivity rises above the threshold point. If the conductivity has not increased for twice the preset number of racks, an Overfeed Alarm will be activated and the detergent feed will stop. Operator intervention is required to restart detergent feed. Rinse Control In Probeless Operating Mode, rinse signal input controls the rinse output. When the rinse signal is present, the rinse pump will run at the programmed speed until the rinse signal goes off. This varies depending on the selected rinse feed option for door machines.

Rack Counts Door Machines For door machines, a rack count will be registered each time the rinse signal toggles from Off to On. Door machines include a rinse feed option which, when set to Rinse on Det, increases the rack count when the detergent signal toggles from Off to On. Alternate Door Machines a rack count will be registered each time the rinse signals toggles from Off to On. Conveyor Machines For conveyor machines, conveyor time is defined as the time it takes to move one rack length. A programmed conveyor time setting is used to count the number of racks on a conveyor machine. A rack is counted when the rinse on time equals the programmed conveyor time.

Rinse Delay Time (Door Machines Only) A rinse delay of 0-19 seconds can be programmed for door machines. The rinse delay will occur at the beginning of each rinse signal input. Rinse Saver (Door Machines Only) The pump will only be allowed to operate continuously for a maximum of 20 seconds. After 20 seconds, the rinse signal input must toggle Off and back On again. Please note, this will also cause the rack count to be incremented The Rinse Pump will only operate if a detergent signal has occurred within the previous 90 seconds. Rinse Feed Option (Door Machines Only) There are two options for when the Rinse Pump will activate.

Option 1 (Rinse on Rinse) will run the Rinse Pump each time the Rinse Signal activates (for the duration of time the signal is present). Option 2 (Rinse on Rinse) will run the rinse pump for a fixed time of 12 seconds each time the Detergent Signal activates. Please note, the Detergent Signal must be toggled On/Off for the rinse pump to run again. With each toggle, the rack count will be incremented.

Tank Change Interval To signal an alarm when it is time to change the tank water, a preset tank change interval can be used in conjunction with accumulated racks since the initial fill. Operating Modes: Probeless Operation Mode

Upon the initial start-up, this screen defaults to allow selection for language of operation.

Additional language choices can be selected if a USB Language Key is available and selectable from the menu at power up. Pressing any key during boot-up skips the splash screen and takes the user to the date and time input screen.

Language Selection The language selection screen follows the splash screen at the first power-up or when a USB drive is in place at power-up. After that, the splash screen leads to the Date and Time Set screen. The language selection screen provides a selectable menu for the languages that are available on the device (or on a language key if one is installed prior to power-up). The screens will always include English and one additional language as default selections. In North America, the additional default language option is Spanish. In Europe, it is German. Language files have an .LNG extension.

Additional languages may be downloaded from a USB Language Key.

To load, power must be turned off. Connect the Language Key and start up. Select a language from the list and load onto the controller. Once a language has been selected, it replaces the second default language choice and becomes the selected language for this controller. English will always remain one of the available default languages. The USB Language Key can be removed as soon as the Date and Time Set screen appears. Date and Time Set The start-up continues with the Date and Time Set screen. The date follows the ISO 8601 standard format with four digits for the year followed by two digits for the month and two digits for the day.

(e.g. 2013/02/15). The time also follows an ISO 8601 standard, but is limited to hours and minutes on a 24-hour clock (for example, instead of 8:00pm, you would enter 20:00).

If a date is entered that is not valid, an error message will appear. Select Enter or Back to return to the Date and Time Set screen.

Two distinct options for additional features can be accessed by the press of a button. The display is in ready state when a pump is enabled in the configuration and the pump name is shown. The display is in active state when a pump is running and the pump name is inversely displayed. Pump names show the first three characters of the pump’s name. (Keep this in mind when naming pumps.) If a pump is not enabled, the three character pump name will be blank. If enabled in the installer setup menu, signal states are displayed as either 0 or 1.

Most recent alarms will be displayed in the alarm status line, when there is an active alarm. If there is no active alarm, this area is blank. (See the section on Alarms for a list of all possible alarms.) The rack count is displayed in five digits. If enabled at system setup, conductivity, wash tank temperature, and rinse temperature are all options for display. Keypad, Menus, and Symbols The keypad is designed for easy operation. Directional keys (Up, Down, Left, Right) let you navigate through menus. The Enter key allows you to enter commands and choices as well as start or stop actions, and the Back key takes you to your previous screen.

Within the display, the selection box highlights your current menu selection. You can change this by using the directional keys on the keypad. Additionally, there are two types of arrows that you may see on the display-- Edit Value and Scroll arrows. When the display shows the Edit Value arrows, use the directional keys to adjust the given value shown. When the Scroll arrow is present, you can use the directional keys to view additional items or options. Flashing black bars indicate when the pump is running.

The default passwords (0123 - Manager, 01234 - Installer) are shipped with the device and works until a new password is selected by the installer or technician. Manager Reports The kitchen manager can download a summary report to a USB key using the 4-digit password set at installation. This password can be changed in the installer menus. Download Productivity Report This screen prompts the manager to install a USB key. Once the report has been downloaded, the screen reverts to the user settings menu.

The report is based on formula run data stored in the controller’s memory. Once the files have finished writing, the user is returned to the main menu. The last file name entered will be shown upon entering the report name screen (unless the controller is reset to factory defaults). The data generated in the reports is based on a date range. The default date range is from the last entered from date to the current date. The installer may change the default range if desired. Once the date range and name have been entered, all reports are written to the drive. If an invalid date/time has been entered, the error screen will appear.

The only report that the manager is allowed to download is the Productivity Report. See the installer menu for additional reports available.

Installer Password The installer uses this screen to input the appropriate 5-digit password for operation. This password is either the default password shipped with the device, or a password programmed in a previous operation. Once the password is entered, the installer main menu screen appears. From here, the installer will adjust settings, input values, or perform data functions. NOTE: To input a password, use the Up/Down keypad buttons to change character (shown on screen display with “Edit Value Arrows”) and Left/Right keypad buttons to change digit.
