Program Parameters Setting
Ramp Rate1:
A ramp consists of a slope(linear gradient) and a target setpoint. The control setpoint
increases or decreases at a linear ramp rate from the actual measured value until a specified
target setpoint is reached. The relative positions of the actual measured value and the target
setpoint determine whether the slope of the ramp is positive or negative. Parameters R1, R2,
R3... express the ramping rate in unites per minute(0.01~99.99), parameters L1, L2, L3... the
appropriate target setpoint in display units.
If R1 = END, the program will be ended when the program runs to the slope.
Target Setpoint 1
:
The target value to which the setpoint ramps when the programmer has been placed into
RVN.
Dwell period 1:
In a Dwell period, the target setpoint, which has been attained, remains unchanged for a fixed
period. All the dwell periods are defined by their duration in minutes with parameters D1, D2,
D3...(0~9999). When the program is running, these parameter display the time remaining in
the active dwell period. If the parameter equals zero, the dwell period is skipped.
When the controller runs in the
PV
displaying status:
1). Select the target program pattern number with the
PTN
/ key.
2). press
SET/PROG
key, the first program parameter appears in the upper display. The
value associated with this parameter will be shown in the lower display.
3). Use
▲
and
▼
key to modify the value.
4). Press the
PAR/SET
key, the next parameter appears. At the same time, the modification
has been saved in the memory. Use
▲
and
▼
key to modify the value.
Repeat this procedure till all the parameters are set. Or if there is no key operation within 16
seconds, the menu times out automatically.
