Function 28 - Constant Adjuster (ADJ)
Operation
This block contains a register which can have its value changed by the <
Δ> and <∇> keys, as long as
one of the following two conditions is fulfilled:
BLK 099/100/101/102
235/236
REGISTER
DSP
a) The block output is connected to a block of Function 06 -Loop Visualization (BLK027 through
BLK030) or of Function 32 - General View (BLK117) and is selected to be indicated on the front
panel display.
b) The block output is connected to a block of the Function 29 - Input Selector (BLK103 through
BLK106) or of
Function 27 - Internal/External Signal Selector (BLK097 through BLK098),
whose internal switch guides the register signal directly to its output. This output must be
connected to any of the visualization blocks mentioned in item a), and must be selected to be
indicated on the display.
The output may range from -102.00 to +102.00%. The lower limit is adjusted in the parameter ALOW
and the upper limit in the parameter
AUPP. The actuation speed is adjusted in the parameter ASPD.
There are three actuation forms:
1) CTYP=0 Continuous Actuator
The output is changed by the <
Δ> and <∇> keys, with continuous increment/decrements of 0.01%.
The maximum changing speed is adjusted by
ASLW. The output will range from the lower limit
(
ALOW) to the upper limit (AUPP).
2) CTYP=1 Discrete Command Type Switch
The keys <
Δ> and <∇> act as a push-button station.
<
Δ> - Put the value adjusted in AUPP, e.g., 100%, in the block output
<
∇> - Put the value adjusted in ALOW, e.g., 0%, in the block output
3) CTYP=2 Discrete Command Type Push-Button
When <
Δ> is pressed, the output signal goes to the Upper Register Limit (AUPP) (normally 100%).
When <Δ> is released, the output signal returns to the Lower Register Limit (ALOW) (normally 0%).
