6)
For a set point that will switch on when the
weight is greater than or equal to the value
motor or solenoid. This can be prevented by using a dead zone to cause the set
point to have one value for turning on, and a different value for turning off. For
example: A set point set to
≥
500 lb with a dead zone of 10 lb will turn on at
≥
500 lb. It will not turn off until the weight goes below 490 lb (500–10). A set
point set to
≤
750 lb with a dead zone of 20 lb will turn on when the weight is
≤
750 lb. It will not turn off until the weight is
≥
770 lb (750+20).
Note: A Dead Zone value of zero is equal to 1/2 “d”.
SP LATCH MENU
The set point Latch Menu is used to latch the set point relay on until it is cleared
manually. There are two standard ways to clear a latched set point:
1)
Program a function key to “RESET SP”.
2)
