MPO for Micro Blender air driven reciprocating mixer.
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.

LIQ For LIQUID COLOR applications using dual pumps / drums.
Liquid Color users generally want the current container of color
to run completely out before switching to a new container. Switching
early requires the transfer of the unused portion to the next
container. This feature allows a standby container to be in place and
ready, and instructs the blender to switch to the backup container as
soon as the first container runs out, as detected by the lack of weight
after a dispense. The default setting is LIQ 01011, which directs that
component 10 is the normal output, and 11 is the component to switch
to. Outputs 10 and 11 must first be prewired to an outlet that is
added to the side plate of the controller. Two additional air
solenoids are also added to drive liquid pumps that require air for
operation.
When conventional pumps are used, two pumps must be present, each
connected to a drum of color. Both would have to be plugged into the
two outlets on the duplex receptacle on the front of the controller.
The parameter would be set to LIQ 00506, which is to say that the
"additive" outlet (output 6) is designated as the back up output for
COLOR (which is output 5).
Other arrangements are possible, but require some wiring.

MCT Monitor Cycle Time
This parameter acts as the ultimate fail safe precaution. When
used, it monitors sequential cycle times, and alarms if a cycle time
exceeds the previous cycle time by an amount that is not consistent
with proper operation. This provides a means to detect mechanical
failures such as a sticking valve or weigh bin gate.
When set to 00000, this parameter is not active.
When set to MCT 02060, an alarm will occur when either a cycle time is
double (02xxx) the previous time, or exceeds it by 60 (xx060) seconds.
At power-on this alarm is always set off and disabled. Once smooth
running is established, the alarm is enabled. Smooth operation is
established using the same logic that Extrusion Control uses.
If the alarm is activated, the display will say (TIME OUT).
Press the alarm silence button to reset the alarm. A new cycle will
also reset the alarm.
If another alarm is currently active (material not dispensing for
example) then this Monitor alarm is ignored or reset.
