To read all data points, use the [
RCD
x
] command, where
x
is 1, 2, or 3.
To set a data point, use the [
SCD
]
command.
For example, the following will set curve 3, data point 27, to the value 123.456:
SCD 3:27:123.456
Note
The curve being edited does not have to be the active curve.
Setting the Pump Speed Pedestal
The pump speed pedestal sets the minimum % position of the valve when in pressure mode.
Use [
SCP
xx
] to set the pump speed pedestal, where
xx
is any percentage value from 0 to 30.
Setting a value of 0 disables the pedestal. The default value is 0 (disabled).
Use [
RCP
] to read the current setting.
Setting Speedup Compensation Parameters
The speedup function is used to compensate for the measurement delay introduced by the pressure transducer.
It has two adjustable parameters:
Speedup compensation constant.
Speedup filter constant.
Both constants have units of time (seconds). The speedup compensation constant should be equal to the
pressure transducer delay, typically in the order of tens of milliseconds. The speedup filter constant should be
set 3 to 10 times smaller than the speedup compensation constant.
To enable the speedup compensator, enter:
SUE 1
To disable the speedup compensator, enter:
SUE 0
To read back the status of speedup compensator, enter:
RUE
To set the speedup compensation constant, enter:
SUT value
To report the speedup compensation constant, enter:
RUT
To set the speedup filter constant, enter:
SUF value
To report the speedup filter constant, enter:
RUF
The following example will enable the speedup compensator and set the speedup compensation constant to
0.05 sec and the speedup filter constant to 0.01 sec:
