To report the value of the phase compensation factor, enter:
RPC
The controller responds with the message [PCvalue], where:
value
: 0 to 100% of the high range phase
For example, if:
Xx value = 20.0
and:
PCF = 75
then:
Phase used for low range = 15.0
Setting the Softstart Rates
The softstart rate controls the rate at which flow move
s toward the desired setpoint. Different softstart rates
can be assigned to each set
point as well as to the valve open and valve closed commands. The softstart rate is
expressed as a percentage of the valve’s full speed, ranging from 0.1 to 100%. If it is not necessary to utilize
softstart control in your process, leave the softstart rate at 100% of full speed.
The [I x value]
command sets the softstart rate for each setpoint, where:
x:
1 = Setpoint A rate
2 = Setpoint
B rate
3 = Setpoint C rate
4 = Setpoint D rate
5 = Setpoint E rate
6 = Analog setpoint rate
7 = Valve open rate
8 = Valve close rate
value: 0.1 (slowest) to 100% (fastest) of valve full speed
To report the
softstart rate for any setpoint, issue the request:
R xx
where xx:
15 = Setpoint A rate
16 = Setpoint B rate
17 = Setpoint C rate
18 = Setpoint D rate
19 = Setpoint E rate
20 = Analog setpoint rate
21 = Valve open rate
22 = Valve close rate
To report the softstart rate for setpoint A, enter:
R 15
