process. To enable the BATCH key, place a 1 or 2 in the 5th (last) position of the
parameter.
Set to one (00001), the unit dispenses until the preset batch amount is reached and then
stops and alarms. Set to two (00002), the unit alarms but continues running when the
preset amount is reached. See KEYPAD section, for full explanations of these 4 keys.
For Micro Pulse devices only
_PO
_PO sets the ON and OFF time of the specified device during the time period that the
RPO
device is operated. This results in a "pulsed' output. This is used in combination with a
NPO
"micro pulse" equipped slide gate. Set to 00000 for normal operation. Set to 00101 for
CPO
pulsed operation. The first three digits (001xx) controls ON time in tenths of seconds. The
APO
last two digits (xxx01) controls OFF time. Larger numbers produce slower dispense rates
without any increase in accuracy. Smaller numbers may not allow enough time for the
slide to shift fully.
Pulsed Output may also assist in dispensing regrind and some powders when these
materials tend to bridge. A parameter of 00501 will produce a 1/2 second open time (5/10
seconds), a long enough time to allow a significant dispense, followed by a 1/10 second
close time, just enough to close the gate fully. The rapid gate movement may help in
keeping material flowing.
For Micro Blender air driven reciprocating mixer.
MPO
MPO sets the timing, in tenths of seconds the clockwise and counterclockwise timing of the
mix blade. MPO 00010 is 1 second for each direction.
_AL Alarm FLAGS
_AL
When material runs out, or for some other reason material does not dispense fully, these
RAL
flags will instruct the controller what to do.
NAL
CAL
The last digit is number of retries before the action.
AAL
The next to last digit is the action:
00000
00001 to 09 = ALARM, Continue retries.
00011 to 19 = ALARM, Stop retries, Continue process.
00021 to 29 = ALARM, Stop retries, Stop process.
00031 to 39 = NO ALARM, Stop retries, Continue process.
00000 = no alarm, no pause in process, no retries. This is the normal alarm configuration
for the Regrind dispense.
00001 to 00009 = sound alarm after specified number of retries and continue retries until
successful. The process will not continue until the fault condition is corrected. The last
digit determines the number of retries before sounding the alarm. This is appropriate for all
important components; natural, color, and additive, and sometimes regrind.
00011 to 00019 = sound alarm after specified number of retries but then stop the retries
and continue with the remainder of the cycle. The alarm will continue until the fault
condition is corrected or until the next cycle begins. The last digit determines the number
of retries before sounding the alarm. This would be appropriate if you wish to make
several attempts at a dispense, such as regrind, but you wish the process to continue even
= NO ALARM, NO RETRIES
