interruption for the full specified DELAY time. To prevent false
starts from the mix blade, a 1 second minimum (00244) is recommended.
Sometimes throughput is slow enough that each new batch buries the mix
blade for a while. When this happens the material on top does not mix
well. To reduce this, you can delay the start of a new batch by adding
to the DLY parameter. The new batch is delayed and the level in the
mix chamber has time to fall before the next batch is added.
======================================================================
LT1 and LT2 (set ONLY if your controller is modified to control
a loader)
The LT1 and LT2 parameters are normally set to all zeros,
indicating that this feature is not present on your system.
If you have additional outputs on your GB/WSB controller for driving
a loading system, then this parameter should be set to some number
indicating how many seconds you will attempt to load before sounding
the ALARM. A sensor input to the controller tells the loader to load.
When the sensor is covered the loader stops. If the sensor is not
covered within the specified number of seconds, the strobe light and
the beeper are activated and the display flashes (LOADER 1) or (LOADER
2), depending on which one has the problem.
The LT1 and LT2 parameters specify this delay time before alarm.
All circuit boards have provision for connecting level sensor
inputs for 2 loaders. When this loader option is being used,
uncovering level sensor 1 will cause pin G (7) of the eight pin
Amphonal plug to be energized. This can be used, through a relay, to
drive a loader.
======================================================================
_PT (for augers and micro pulse devices only)
The _PT parameters will cause the first try dispense to be a
percentage of the full target weight. For example, with color set to
(CPT 00090), the first try will be 90 percent of the full target
amount. Retries then occur, but each will target only 50 percent of
the remaining requirement. A series of progressively shorter retries
should be expected, until the retry parameters are satisfied (RP and
RD). The _PT parameter is most effective for slow dispense devices,
like augers. When setting _PT, also set the _RP parameter to 00001.
This forces retries up to within 1 percent of target, instead of 10,
improving accuracy.
======================================================================
_WT and _TI (adjusted automatically after each cycle)
The _WT, and _TI parameters are related to the flow rate or
dispense rate of each material. These can be changed manually or set
AUTOMATICALLY by using the RATE CALIBRATION routine described in the
KEYPAD section of the manual. These numbers are automatically
corrected as necessary after each cycle.
_WT and _TI are WEIGHT and TIME numbers that, taken together,
represent the actual flow rate for the specified material (WT/TI).
