2.8Setting up a standard temperature application

Using a 1000 ohm Ni RTD,

L & S # 556-541 –13 °F to +203 °F

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.
