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.
