How to Avoid Data Loss CAUTION 11 : Avoid Corrupting Formula Data—Never turn the Run/Program keyswitch from the Program position to the Run position unless the display says OK Turn Key to Run.
Chapter 2. Programming Supplement 3 What are Formulas, Steps, and Decisions? In this manual a wash formula is all actions automatically performed by the machine from when the operator starts the loaded machine until the machine stops all operations. The end of a formula is usually indicated by an audible operator signal. Formulas are made up of several types of steps, each with several variables which are determined when the operator or other qualified person programs the formula.
Chapter 2. Programming 2.3.3.2. Moving Forward and Backward through Steps and Decisions—Each step has two displays: Page A and Page B. Display or Action 2.3.3.2.1. Explanation 03 TMMQFFFHC SCWSS* 01 This is Page A. In this example, the “03” at the left end of the display represents the formula number. The “01” below it represents the step number within that formula. The CWSS* decisions shown in bold repeat for each chemical programmed in this step. 03 SPD D E 01 This is Page B.
Chapter 2. Programming 2.3.3.3. Create a New Formula—Creating a new formula with the E-P Plus® controller entails adding and defining steps using one of the existing but blank formula numbers. Display or Action Explanation PROGRAM 1 MENU ADD/CHANGE FORMULA y Accesses the formula list for selection of a formula number to change or create. This is the Add/Change Formula display. From this display, either back up to the Program menu, or begin creating or changing a formula.

Cursor blinking on step number indicates that adding or deleting a step is allowed. Provides a help screen for inserting and deleting steps, as shown below. This is the help screen for inserting and deleting steps.
Chapter 2. Programming Display or Action Explanation 03 TMMQFFFHC LSCWSS* 01 0 This is a typical Type of Step decision display. The actual format of the display varies according to the specific machine controller and certain configure decisions. End formula: The last step of each formula must be of type 0. This step is automatically added as a last step if the previous step is type 6 (final extract). The basket moves or stops as directed by the How to End programming decision, described in Section 2.3.
Chapter 2. Programming Display or Action Explanation CAUTION 13 : Avoid damage to extract motor—For H_J model machines with software date code 95005 or earlier, the minimum valid time for a final extract step is 1:45 (MMQ=013). Attempts to program final extract steps shorter than 1:45 may cause the controller to continue indefinitely in high extract.
Chapter 2. Programming Display or Action Explanation 03 TMMQFFFHC LSCWSS* 01 x Control of cold water valve 0 Cold water valve off 1 Cold water valve on 2 invalid response—not allowed 3 Lowers temperature of filling water. See Supplement 4 “How to Modulate Water Valves to Regulate Incoming Water Temperature” for more information. 03 TMMQFFFHC3LSCWSS* 01 x Third water only appears if machine is supplied with and configured for this option.
Chapter 2. Programming 2. The machine must be configured for temperature control (Temp Control = YES) as described in Section 2.3.4.2. 3. The machine must be configured for cooldown (Cooldown Error = 1, 2, or 3) as described in Section 2.3.4.2. 4. The bath step with the high temperature must immediately precede the cooldown step, and it must have a temperature programmed in degrees (for example, 180 degrees Fahrenheit).
Chapter 2. Programming 5. When the one-minute step time expires, the cooldown valve closes and the drain opens. The drain remains closed only if the machine was programmed to not drain, as to prolong the cooldown or allow the injection of chemicals into the cooler bath. Display or Action Explanation This display results from commanding all water valves off (0) in a bath following an extract step, or if a temperature was not specified in the previous bath step. ILLEGAL COOLDOWN STEP.
Chapter 2. Programming 2.3.3.5.5. How to Select the Steam Code Display or Action Explanation 03 TMMQFFFHC LSCWSS* 01 x 0 Appears only if the machine is supplied with and configured for temperature control (Temp control=yes) and steam (Steam error greater than 0). no steam in this bath The available steam codes are combinations of three yes/no decisions, as described below. These decisions are summarized in Table 6. • Early defines when steaming should begin.
Chapter 2. Programming Table 6: Summary of E-P Plus Steam Code Choices Steam Code Steaming can begin at the earliest safe level Steaming can occur after temperature is initially achieved Step timer runs or stops while steaming to the desired temperature.
Chapter 2. Programming 2.3.3.5.6. Injecting Chemicals Display or Action Explanation 03 TMMQFFFHC LSCWSS* 01 x Chemicals can be added to any bath other than a cooldown bath. A standard chemical injection can be prevented by commanding C = 0 (no chemical in this bath) or by commanding SS = 00 (zero seconds of chemical inject time). Up to five chemical injections per bath step are allowed.
Chapter 2.
Chapter 2. Programming 2.3.3.5.7. Concluding Decisions Display or Action Explanation Select the wash speed for this step. The default value is Wash 1 for factory-supplied formulas and new bath steps. 03 SPD D E 01 x 0 Wash speed 2: High wash speed for use with goods requiring less mechanical action. Mechanical action is reduced because the higher speed reduces the distance the goods are dropped. 1 Wash speed 1: Normal wash speed.
Chapter 2.
Chapter 2. Programming Display or Action Explanation 4 Stop with drain—The basket is kept stationary while draining to prevent abrasion from mechanical action. During the fill phase of this step, basket motion is controlled by the Type of step decision. This selection is not valid if the next step is an extract.
Chapter 2.
Chapter 2. Programming Note 5: End Codes 4, 5, 6, and 7 automatically shut off the operator signal two minutes after it begins sounding. The controller runs during this period to count down the time remaining for the signal to sound and turn it off when time expires. Because the controller remains active, silencing the operator signal manually before the two minute signal ends is the same as terminating the formula. Press o to terminate the formula, thus silencing the signal.
Chapter 2. Programming Display or Action Explanation CAUTION 18 : Ensure programming changes are saved—If the program key is turned to R at this point, all programming changes will be lost when power to the machine is turned off. Later software versions allow the person programming the machine to correct the error, as described below.
Chapter 2. Programming codes are discretionary and are so indicated below, most configure codes must match those shown on the metal configuration nameplate unless optional equipment has been added to or removed from the machine. 2.3.4.1.

Chapter 2. Programming Display or Action Explanation Select from options 1 through 3 if steam is available: 1 = 5 minutes, 2 = 10 minutes, and 3 = 50 minutes. The number of minutes selected is the maximum time that the machine will steam in an attempt to achieve the desired temperature before a steam error is displayed. This self-clearing error does not stop machine operation.
Chapter 2. Programming Display or Action LEVEL 2 HEIGHT ? 8 Explanation This value is the depth of the water measured from the bottom of the cylinder shell. This level will be used for any programmed bath step commanding Level 2. The minimum valid value for this decision is equal to the value of the Level 1 Height configured just before. Use the same procedure to configure Levels 3 through 6 that you used to configure Level 2.
