THE PROGRAMMABLE CONTROL SYSTEM MK-IV User’s Manual
General descriptions MODES The system contains six different modes: 1. MANUAL MODE: The mode when the mixer is operated like a manual controlled mixer. Instead of executing a programmed recipe, the mixer is started and operated until it is manually shut off. 2. PROGRAMMING MODE: The mode where all programming and editing takes place. 3. PROGRAM MODE: The mode where all programmed recipes are executed. 4. FIXED MODE: A pure executional mode , mixer will only run the programmed recipes.
The Keypad The Keypad is used for entering data to the system. ITEM FUNCTION EXPLANATION 1. Program No. Displays the program Number being executed. 2. Step Displays the step number being executed. 3. Speed Displays the set-speed. 4. Time Displays the elapsed time since start or displays the remaining time to shut down. 5. Text Area OVERLOAD: MIxer cannot maintain set speed, too much mix or speed set too high. MIN SPEED: The mixer is running at absolute minimum speed.
ITEM FUNCTION EXPLANATION 6. Enter Used for stepping through a program. 7. CLR Clears a flashing display. 8. Speed up/down arrows. 9. Time up/down arrows. Used for adjusting the the speed while the mixer is running. Used for adjusting the the time. 10. Program Used to enter/exit program-programming mode. 11. Pause Pauses the mixer without losing recipe. 12. Numeric keys Used for setting time and speed. 13. Emergency Stop Stops the mixer instantly. 14. Start Starts the mixer. 15.
How to run the mixer manually. SPEED Mode. Enter the speed desired. Push Enter the time desired. Push Push How to input a program. A flashing display indicates that it is expecting the operator to key in a value. A step is always a combination of speed and time. An example is 100 R.P.M. for 5:00 minutes or 0 R.P.M. for 15 seconds (which is a 15 second pause) Please note that the mixer will not start automatically after a pause, the start button must be pushed to proceed to the next step.
To program a recipe. Push “HOLD FOR 3 SECONDS” Push Push Enter the speed desired. Push Enter the time desired. Repeat this process for as many as 9 steps per program, after the 9th step , the next program number will display, ready to enter a new recipe.This will continue up to 25 programs. Example To edit a recipe or to correct mistakes, use the same step above to enter the programming mode, then push “ENTER” to reach the program/step that you wish to edit.
To run a programmed recipe. Push Enter the Program number. Push Push After the ENTER key has been pushed, the data in step 1 will be displayed along with the program number. After the last program step has been executed, the mixer will slow to minimum speed and shut off. The mixer can be stopped at any time during a recipe by using the “PAUSE” button, the mixer will slow to stop and the recipe will not be lost. To continue on with the same recipe, push “START”.
To enter “FIXED MODE” Push “HOLD FOR 3 SECONDS” Push “99” Push Push “1 2 3 4” Push Push the program number.
Control Data for Program 26 Program 26 contains the control data required by the computer to operate. This data differs from model to model. To access Program 26. Push “HOLD FOR 3 SECONDS” Push “26” Push Push “1 2 3 4” Push until you reach Step 7. Push Enter the value on the following chart that matches the mixer model. Repeat for step 8 and 9.
In the electronics fail. A D B C It is possible to bypass the control system if the electronics fail. Please note, when the system is bypassed, the safety devices do not operate. Extreme care should be taken when operating the mixer. 1. Switch off the main power. 2. Open the top lid, flip the dip switch (B) on the back of the computer control from “Auto” to “Manual”.(NOTE: The front L.E.D. lights will not display in “Manual” mode) 3. Disconnect the “Speed Reg” Harness(C). 4.
Error Codes A error in the mixer will trigger an ERROR code in the time display. See the chart below for an explanation of error codes and the procedure for correcting them. E:401 E:201 E:301 HOT E:201 The servo motor block actuator (B) did not contact the minimum speed microswitch (A) after the stop button was pushed or the programmed recipe completed. The computer is programmed to slow the mixer down to low speed before shutting off.
E:301 There is no signal from the speed pickup (hall effect sensor). To correct this error: 1) Check that the sensor (D) is centered directly above the track of the 3 magnets (F) on the pulley and the gap between the sensor and magnets is 1/16”. If not , bend and / or move the bracket (I) holding the sensor. 2) Inspect the three wires between the sensor and the plug. Replace the sensor if wires are broken. 3) Insure the aluminum disc (E) is tight on the pulley.
E:4:01 The values in program 26 steps 7, 8 and 9 are missing or incorrect. To correct this error: Push “HOLD FOR 3 SECONDS” Push “26” Push Push “1 2 3 4” Push until you reach Step 7. Push Enter the value on the following chart that matches the mixer model. Repeat for step 8 and 9.

Belt adjustments NEVER move the base for motor (R)(in the oblong holes) , this is a factory setting and is NOT used to tighten the belts.If the entire unit is to be exchanged, reference the below table. Models W30-W40(P) Distance (B) 11 1/2 inches Models W60-W150 Distance (B) 12 1/4 inches 1. Start by tightening the V-belts (C). 1.A) Loosen the bolts (D) and the jam nut (E). 1.B) Tighten the bolt (F) until the V-belts are tight, ........tighten the the 2 bolts (D). ...C) Back bolt (F) out away from arm.
Belt Exchange 1. Loosen Bolt (J) and remove washers (H). 2 2. Remove cotterpin (T) and dowel pin (E) from servo linkage. 2 . 3. Remove vari drive belt (A) from pulleys. 2 4. Remove Hall Effect sensor (X) from the rear of the computer. 3 5. Loosen bolts (D) and remove the front v-belts (C) by tilting the center pul ....ley assembly (L) forward and rolling the belts (C) off the front pulley one ....at a time. The belts can now be threaded between the lower fork (M) and ....the lower movable pulley.
