SETUP
SYSTEM
DEFAULT % HOT WATER
If hot and cold water are to be mixed by percentage, enter the percentage here. The
Spectrum will dispense the percentage of hot water first, and the balance using cold water.
If the percentage of hot water is altered on the Batch Setup Screen, the change will be
remembered for future loads. This value does not appear on the Order Entry Screen.
DEFAULT HARSHNESS ( x 10 )
This value allows the ratio of sand and stone to be altered from a base of 1.0. A
value of 1.0 assumes the sand and stone in the mix design is ideal. However, if more sand
is needed than stone, the Spectrum will increase the sand weight by 20 Lbs per yard for
each 0.1 increase of default harshness and decrease the stone weight. Subsequently, a
0.1 decrease will subtract 20 Lbs sand and add 20 Lbs stone.
The Spectrum multiplies the entered value by ten to place the decimal. For
example, enter 10 to mean 1.0. DO NOT set this value higher than 20.
DEFAULT AIR EFFECTIVENESS ( x 10 )
This value allows any changes in the air entraining chemical effectiveness to be
compensated for without altering the basic mix design. This is beneficial when climatic
changes affect the air entraining effectiveness throughout the day. Normally a value of 10
is set, which represents 100%.
INITIAL GATE CLOSE WAIT
Before a batch, the Spectrum will pulse all discharge gates shut for the time
specified. All gate checks are done after this time has elapsed. Normally this value is set
to 500 mSec (1/2 second).
MAX NUMBER OF BATCHES ALLOWED
This parameter restricts the number of partial batches allowed in a load. If too many
batches are required to make the load, an error message is displayed. Typical values are
1 or 2.
