Controls all power to the controller and all outputs. When power is switched off, battery backed-up RAM preserves all internal totals and parameters. All other functions are reset for normal start-up when power is restored. 2. STOP END OF CYCLE / CONTINUE switch This is the PREFERRED STOP switch. This switch is wired in series with the level sensor. Turning it off breaks the signal to the computer the same as covering the level sensor with material. This stops the process at the end of a full cycle. 3. IMMEDIATE PAUSE / CONTINUE switch Causes a computer-controlled immediate pause in the cycle. Dispenses will stop in mid dispense if necessary. When switched back to CONTINUE, the process continues without any error in amounts dispensed. 4. REGRIND thumbwheel switch (00 to 99) This setting represents the PERCENT of the ENTIRE MIX that is to be REGRIND. A lower limit of 5% (05) has been entered into the software. This limit may be altered using the keypad (see parameters, RLO). A setting of "99" causes the system to run 100 percent regrind. With this setting, no attempt is made to meter natural, color, or additive unless the regrind dispense fills less than 1/2 of the weigh bin. 5. COLOR thumbwheel switch (00.0 to 99.9) This setting represents the PERCENT of the NATURAL PORTION that is to be COLOR. For example, if your COLOR to NATURAL mix ratio is 1:25 then "04.0" is the proper setting. (1 pound of color to 25 pounds of natural is 1/25 = 4%) 6. ADDITIVE thumbwheel switch (00.0 to 99.9) This setting represents the PERCENT of the NATURAL PORTION that is to be ADDITIVE. For example, if your ADDITIVE to NATURAL mix ratio is 1:100 then "01.0" is the proper setting (1/100 = 1%). Page 21 7. ALL AIR SOLENOID outputs This is a single 17 pin Amphanol plug located on the front of the control panel. This provides 24 volt power for the NATURAL, REGRIND, WEIGH BIN DUMP, and FLOW CONTROL (optional) air solenoids. On Models 140, 240, 440, 940, and 1840 (FOUR valve units), COLOR and ADDITIVE dispense valve solenoids are also powered. These power sources are transistor driven and are protected by the 1/2 amp panel fuse. See the wiring diagram section for the correct wiring to each pin. 8. COLOR and ADDITIVE power outlets (certain models only) Each outlet puts out 120 volts (220 volts outside U.S.A.) through internal plug-in solid state relays rated at 5 amps and fused at 3 amps. These relay outputs are designed to drive motors or other devices requiring power up to 3 amps each. The COLOR outlet is driven based on the COLOR setting. The ADDITIVE outlet follows the ADDITIVE setting. COLOR dispense occurs first but has no effect on the ADDITIVE dispense. The amount of each dispense is calculated based on the NATURAL dispense that precedes them. 9. EIGHT CHARACTER DISPLAY Displays the accumulated total bin weight, in grams, 2 seconds after each dispense. The display flashes when an inadequate dispense has occurred and the dispense is going to be retried. Other information displayed here includes material usage totals, internal parameters, current thumbwheel settings or keypay entered settings, and various information prompts to assist the operator. ####.# Numbers displayed are the total weight of material, in grams, in the bin at any time. The weight in the bin is updated 2 seconds after an each dispense is completed. During the dispense the displayed weight does not change. P in the left most position indicates unit is in PROGRAM mode. M indicates unit is in MANUAL mode. R, N, C, or A indicates the component being dispensed. INVALID indicates: 1. you pressed an incorrect key, 2. you pressed a key for a function that is not active, or 3. you are not in the right mode for this key to operate. PASSWORD is displayed when you press the "*" key from the normal mode. Enter "11111" for MANUAL mode or "22222" for PROGRAM mode or enter your own password number if you have established one. SETTING, OPERATE, TIMED, and CALIBRATE are displayed when the respective keys are pressed from the manual or program modes. These displays are followed by pressing a device key; REG, NAT, COL, ADD, DUMP, ALARM, MIX, or HOLD. FLASHING means that retries are occurring because the first dispense was not enough. Other error conditions also cause flashing. ROM OK or ROM BAD indicates condition of ROM chip. See KEYPAD, *25 for explanation. Page 22 10. LED LIGHTS The LED lights in two vertical columns of eight located above the 8 character display indicate the following: LEFT COLUMN: 1. REG Regrind dump solenoid operating. 2. NAT Natural dump solenoid operating. 3. COL Color drive relay operating. 4. ADD Additive drive relay operating. 5. DMP Dump valve solenoid operating. 6. ALM Alarm output operating. 7. MIX Mixer motor drive relay operating. 8. HLD Mixer flow valve is open (Optional). RIGHT COLUMN: ALARMS 1. Alarm is on because Regrind ran out. 2. Alarm is on because Natural ran out. 3. Alarm is on because Color ran out. 4. Alarm is on because Additive ran out...
