NOTES

1. The cycle counter cannot be programmed. It can be cleared in the Program Mode by editing the value and pressing both the

and

keys

simultaneously. 2. This parameter restricts valve movement to between the two values. The lower shaft limit must be less than the upper shaft
limit. 3. The setpoint limit must lie within the range of the Process Engineering Units. 4. When the process lower and upper value are edited,
pressing both the

and

keys simultaneously will change the system decimal point. The possibilities for decimal point location are xxx, xx.x,

x.xx, and 0.xxx.
