FEATURES

  • Five Modes of operation
    o Formula Select Mode – Each pump receives a trigger from the machine supply valves and then performs the delay and dispensing as programmed. A trigger qualifying time may be programmed to ignore short valve cycles.
    o Push Button Mode – When the button on the front of the dispenser or the “start” button on the VLR (Dairy Clean Remote, formula selector) is pressed, all pumps delay for a programmed time and then dispense the programmed amount of chemical.
    o Flex Trigger – This allows any pump to operated using any trigger. A pump can be programmed to operate with multiple triggers.
    o Sequence Mode – This allows the pumps to be triggered using the drain valve or similar signal from a controller. It is possible to use the hot and cold fill valves as well.
    o Relay Mode – This will cause the pumps to directly respond to trigger inputs.

Installation

Electrical Installation – Main Power and Trigger Signal Wiring
All installations must be in accordance with city, county, parish, state or provincial electrical codes and should be performed by a certified electrician. A ½” nonmetallic conduit system must be used to install the power cord. For questions, please contact local licensed electrical contractor.
Caution: Before electrical installation is started all electrical power must be turned off to any trigger device or controller at the appropriate service panel. Lockout and tag out procedures must be used. There is a potential for exposure to high voltage conditions when the Dairy Clean enclosure is opened.

A complete survey of the site installation should be completed in advance of starting the Dairy Clean installation.

  1. The Dairy Clean is prewired with a power cord that includes a 115VAC grounded plug. Simply plug the power cord in grounded 115VAC wall outlet for main power.
    a. Wall plug/socket adapters may be used to plug the power cord into various country plug configurations. The adapter must be rated to accept 115/230VAC 10A.
    b. Alternative Main Power Hardwire– The molded plug can be cut off and connected directly to an alternate power source. The operating voltage 100-250VAC 50/60HZ. The system will automatically adjust to the incoming voltage. Machine ratings and instructions must be observed. Consult with equipment manufacturer for connection information.

  2. Select a location to mount the Dairy Clean on a wall that will allow access to the chemical product containers and the chemical product feeds points on the machine. Direct spray or high steam areas must be avoided.

  3. If using the 951 series flush manifold or any other flush manifold , select a location that will allow all the electrical (power for solenoid valve and/or pressure switch) and tubing connections to be accessible. It should be noted that the flush output on the electronic control board is a 24VDC signal. The solenoid coil for the flush valve will need to match this output signal.

Trigger Signal Wiring
It is possible to cutout supply signals from the machine that fall below 70VAC by using the voltage cutout switch.

When the Dairy Clean enclosure is opened the voltage cutout switch can be accessed.

  • When this switch is set to the 12V-100V setting the system can accept supply signals from the machine that range from 12-250VAC. This is the factory default setting for any product.
  • When this switch is set to 100V-240V, the system can accept signals that range from approximately 70250VAC.

Note: When combining 2 or more trigger signal inputs from one supply signal from a controller, it is recommended to have the voltage cutout switches set to 12V-100V settings.
The system will accept 12250VAC trigger signals.
See the wiring configuration table on the next page for definition of the various wires.

Dairy Clean Wiring Configuration (For Sequence Mode) (For Formula Select Mode or Relay Mode)

Trigger
Input| Line (signal)| Common| Function of Trigger Input
Sequence Mode| Formula Select/Relay Mode
1| Black| White| Event Trigger| Signal Pump 1
2| Brown| White| Event Trigger| Signal Pump 2
3| Red| White| Reset (opt’l) ex.
door switch| Signal Pump 3
4| Orange| White| Not Used| Signal Pump 4
5| Green| White| Signal Pump 5
6| Blue| White| Auto Formula Select (see AFS note)

Sequence Mode Trigger Wiring
There are two methods to wire for sequence mode

  1. Use the normally open solenoid drain valve. Connect the “black” and “white” wires parallel to the solenoid drain valve. See wiring diagram for appropriate connection points.
  2. Use hot and cold fill solenoid valves. Connect the “black” to one valve, the “brown” to other valve, and the “white” to a common. See wiring diagram for appropriate connection points.

Auto Formula Select

  • Auto Formula select allows the formulas to be selected based on a trigger signal that is received from the controller. The following list outlines the setup of this feature:
    o The 6 th trigger input (blue wire) on the Dairy Clean is used for this purpose.
    o A trigger source that can be programmed at the controller will be required. The timing of this trigger source is what determines which formula is selected by the Dairy Clean control board (IQ-50).
    o To determine the amount of signal time for any formula simply calculate as follows: Multiply the formula number by 2 – Example: Formula 7 needs a trigger signal equal to 14 seconds. (7 X 2 = 14).
    A 14 second trigger signal to Dairy Clean input number 6 (Blue and white wires) will change the Dairy Clean to formula 7.

End User Remote
The Dairy Clean can be ordered with Dairy Clean Formula Selection Remote. The remote is used for two reasons;

  • To select wash formulas manually
  • To start a formula program when the system is setup in “push button” mode (see operation mode in programming section for more information).
  1. Turn power off to the Dairy Clean using the power switch on the bottom of the Dairy Clean control module.
  2. Remove the (4) screws on face plate and loosen the face plate to access the control board.
  3. Remove the one of the white plugs on the bottom of the Dairy Clean control module.
  4. Phish the remote cable thru the hole and up to the control board and plug into the black RJ jack (similar to phone jack).
  5. Use the supplied strain relief piece that will surround the remote cable and plug into the hole at the bottom of the Dairy Clean control module.
  6. Reassemble the face plate and reinstall the (4) face plate screws.

Operation Mode Descriptions

  • Formula Select – This mode causes each pump to run its delay and run time for the selected formula in response to the respective trigger input. Trigger 1 will run pump 1, trigger 2 will run pump 2, etc. The Trigger Time setting allows a qualifying time to be set to avoid false triggers because of stray signals. Trigger signals for this mode are typically found on supply valves.
  • Push Button – Selecting this mode causes all pumps to run when the ENTER key on the front of the Dairy Clean or the START button on the VLR remote is pressed on one of the formula screens. All delays will start immediately with the key press and the pumps will run when the delays expire. Lockout will also be active. This prevents accidental retriggering.
  • Flex Trigger – Flex Trigger mode is similar to Formula Select mode, but each pump can be programmed to operate from any trigger. Any pump can be programmed to operate with multiple triggers as well.
  • Sequence – Sequence mode allows automatic triggering of pumps when conventional supply signals are not available. Each pump delay and run time occurs in response to a sequential event from an external controller. The most typical way to use Sequence mode is to hook up the trigger signal number 1 input (black wire) and the common (white wire) to the drain valve, which is a normally open valve on most machines. Each time the machine fills the drain valve is energized to the closed position. The trigger signal input number 1 will register the signal and count it as a fill. The system can be programmed to run pumps at any fill along with programming a final fill thus resetting the sequence count for a new wash cycle. As an alternative, the hot and cold fill valves can be used. In this case connect the trigger 1 to the hot valve and the trigger 2 wire to the cold valve. The common wire (white) may need to be split using a wire nut and a couple of short pieces of wire to complete the trigger circuit so that each valve will have the common wire connected.
  • Relay – This mode causes the inputs to directly drive the outputs. No pump programming is required. If six pumps are used, pump six must be assigned to one of the first five trigger inputs. If a flush is used, the flush time may be programmed for each formula.
