- Formula Programming
- Pump Stand Configuration
- Pump Calibration
- Prime Pump
- Set Sequence (Drain mode)
- Flex Trigger assignment
- Trigger Assignment
- Flush Pump Assignment
- Copy Configuration
- Clear Load Counts
- Test Formulas
- Set Factory Default
-
Formula Programming – Program and setup for each formula. Assign formula number and formula name, load count pump. Program chemical pump delivery amounts for each pump. The pump run times can be in seconds, ounces or milliliters. Each pump can be programmed with 3 different amounts per formula (levels). Additionally, each pump can be programmed with a delay.
-
Pump Stand Configuration – Program and setup for the following:
- Operation Mode
- Flush Time
- Units/Capaall Date
- Default Formula
- Bleach Pump
- Trigger Time
- Auto Formula Select
- AFS Calibration
- Swap STUs
-
Operation Mode – 4 Different operation modes are available.
- Formula Select – Various formulas are set up and each chemical pump is triggered for chemical. Pump run times are programmed at Aurora based time or volume. Relay – All pumps run “one to one” with the chemical supply trigger from the laundry machine. Pump run times are programmed at the laundry machine based on time. Sequence (Drain) – All pumps run from Trigger Signal 1 and/or 2. The electrical signal to the drain valve on the machine that is active for each fill is used to call for chemicals. Simply program which pumps to run for each laundry machine fill during the wash cycle.
- Flex Trigger – Each pump can be programmed to run with each trigger. This includes running a pump two different times from two different triggers.
-
Flush Time – Program the flush valve run times. Two flushes are available. If a value above zero is entered the flush is automatically active and will flush when a pump runs. The flush will continue to run for the amount of time that has been programmed. If a value above zero is entered for flush 2, then a prompt to assign pumps to each flush will occur.
-
Units/Capacity – Program the desired unit for chemical amounts. The choices are seconds, ounces, and milliliters. If ounces are milliliters are selected, pump calibration will be required for each pump. Additionally, the machine capacity can be entered. The machine capacity is used for reporting needs where calculations concerning pounds or kilograms are desired.
-
Name/Install Date – Program the name of the pump stand and the date that it was installed.
-
Default Formula – The Default Formula is a formula that is prompted every time the load count pump is triggered. This will leave the Aurora setting at the desired Default Formula at the end of each wash cycle. The Default Formula is often set up as a color-safe formula in the event the end user forgets to change the formula when starting the next wash cycle. At least one formula must have pump run values to be able to set up the Default Formula. If there is not at least one formula set up, then the message “No Active Formulas” will be displayed.
-
Bleach Pump – Assign any of the pumps to be the bleach pump. The bleach pump will not simultaneously with any other pump. If the bleach pump is triggered simultaneously with other pumps, either the bleach pump or the other pump will run first, once completed, the other pump will run. ****
-
Trigger Time – This is the amount of time that the chemical supply trigger signal is active to validate and run a pump. The default setting is 5 seconds. It can be set from 1 – 90 seconds
-
Auto Formula Select – This allows the formulas to be selected based on a trigger signal that is received from the laundry machine. The following list outlines the setup of this feature: The 10th trigger input (gray wire) on the Aurora Connect is used for this purpose. A trigger source that can be programmed at the laundry machine will be required. The timing of this trigger source is what determines which formula is selected by the Pump Driver Module (84.439.1). To determine the amount of signal time for any formula simply calculate as follows:
- Multiply the formula number by 2 then subtract 1
- Example: Formula 7 needs a trigger signal equal to 13 seconds. (7 X 2 = 14 then 14-1 = 13). A 13 second trigger signal to STU input number 8 (gray and white/tan wires) will change the Aurora to formula 7. When Auto Formula Select is set to off, input 10 (gray wire) is available as a trigger input. (See I-1227
-
AFS Calibration – The AFS can be calibrated to select the correct formulas when the timing of the trigger signal from the machine chooses the incorrect formula. Immediately after the AFS trigger signal, simply enter the expected formula number and the actual formula that was selected. The system will then calculate and make an adjustment in how it reads the AFS trigger signal. The correction will adjust other formulas both lower and higher proportionally.
-
Swap STUs – The Aurora can accommodate 2 Pro-Connect DR’s to support a greater number of pumps. The Pro-Connects are automatically assigned STU 1 and STU 2. The assignment can be found by looking at the front of the Pro-Connect DR front face and the assignment is shown at the top. The Swap STUs function will flip the assignment.
-
Pump Configuration – Program a chemical name for each pump. Additionally, the speed of the pump can be adjusted from 25-100% of the rated speed of the pump motors. Typically Aurora pump stands are equipped with 105RPM pump motors (max speed).
-
Pump Calibration – Calibrate pumps for ounces or milliliters programming. The Aurora will accurately calculate pump calibration rates automatically. With the desired pump number highlighted press Enter and the pump will begin to pump. Simply catch the media coming out of the pump with a graduated cylinder and allow to run long enough to catch at least 8 ounces or 250mL. Then press Enter to stop pump and a prompt will come up to enter the amount that was caught. Enter the amount and the Aurora will calculate the pump rate. Note: Pump rates can be entered manually by highlighting the oz/min or ml/min column and pressing Enter
-
Prime Pump – Select the desired pump and press Enter. Press Enter again to stop pump.
-
Sequence (Drain) – Program the Aurora to deliver multiple chemicals at various points through a wash cycle from a single trigger source. Often the drain valve is used to provide the trigger. During each fill of the laundry machine the drain valve is energized with an electrical signal. The Aurora can be programmed to deliver chemical at any of the fills (energized drain valve) during the wash cycle. Simply choose the formula, the S1-14 on the left side are the sequence events (fills on the machine). The 1-14 above are the pumps. Highlight the ovals and press Enter on desired sequence/pump ovals. Note: Use the “F” at the end of the pump numbers to program the final event (final fill of the wash cycle). This will reset the events so that the next wash cycle will start with sequence event 1.
-
Flex Trigger – Program the Aurora to deliver any chemical with any trigger signal. Select the desired formula. The 1-14 above are the pumps, the T1-20 are the trigger signal inputs. Highlight and press Enter on the ovals for the desired chemical deliveries.
-
Assign Triggers – The Aurora by default is set to use trigger signal 1 to operate pump 1. This is true for all triggers and respective pumps. Assign Triggers will allow each pump to be assigned to a different trigger. Example: Pump 2 could be assigned to operate from trigger 1 along with pump 1.
-
Flush Pump Assignment – When using more than one flush valve, pumps need to be assigned to operate with either Flush 1 or Flush 2. The Flush Pump Assignment will program in the assigned flush.
-
Copy Configuration – The Pro-Access DR can be connected to a network of 8 Aurora pump stands. This function allows the system to copy programming from one Aurora pump stand to another.
-
Clear Load Counts – This function will clear the load counts on all Aurora pump stands.
-
Test Formulas – Test the output of any pump in any formula on any Aurora pump stand. This is used to confirm the desired amount of chemical is being delivered to the laundry machine
