2.9 Setting up a standard pressure application

Using a QBE sensor,

Siemens part # QBE620-P10 [P10 is 150PSI]

Configure

If no keys are pressed for 20 seconds, the controller will exit this mode, and return to the basic display.

See Hint section 2.2, ‘How to configuration your RWF40”. (From the basic display, or user level,

press and hold, for 3 seconds, and then release, and again,

press and hold, for 3 seconds, and then release)

The actual value display, (9030)

shows the current configuration item value.

The setpoint display, (C111)

shows the configuration item you are adjusting.

The display is steady, (not flashing) and by default, the 4th, (rightmost) digit may now be adjusted.

You can select which digit you wish to adjust, by

pressing once and releasing it. The 3rd digit is now flashing, indicating that it is now, the adjustable digit.

Cycle thru each digit of C111 and configure as charted

below, then accept by pressing and releasing.

All four upper digits will flash once, and the new configuration value, is displayed in 4 steady digits.

Press and release, to configure C112, C113, … thru Df1.

Set parameters

See Hint section 2.3, ‘How to adjust parameters’

The actual value display, (0) shows the current parameter value.

The setpoint display, (AL)

shows the parameter item you are adjusting.

Increase or decrease the value, accept it by waiting 2 seconds.

Once it flashes, proceed to the next parameter

(HYSt) by pressing and releasing.

Adjust all of the parameters as shown below.

Parameter level values:

Value	Item	Description	* Sec
160	AL	Limit value for comparator	8.2
5	HYSt	Switching differential for limit comparator	8.2
10	Pb.1	SPE setpoint external	9.2
80	dt	Derivative time	9.2
350	rt	Integral action time	9.2
-5	HYS1	Burner-on 5 °F below setpoint	5.5.1
3	HYS2	Burner-off, 2-stage	5.2.3
5	HYS3	Burner-off 5 °F above setpoint	5.5.1
0	q	Response threshold	5.6
1	H	Heating curve slope	5.5.1
0	P	Parallel displacement	5.5

Set user level values

See Hint section3.4, ‘How to change a setpoint’.

You may enter the user level, directly from the basic display.

Press and release.

The actual value display, (180)

shows the current user level item value.

The setpoint display, (SP 1)

shows the user level item you are adjusting.

Increase or decrease the value, accept it by waiting 2 seconds. Once it flashes,

press and release.

Adjust SP1 as shown below.

User level values:

Value	Item	Description	* Sec
100	SP 1	Set point 1	.5.5.1

Setup is complete!
