• Press and hold button while switching

on power to the D20, keep the button

pressed for 6 sec. The eeprom will now

be erased, and then all three LEDs are

lighted. The LEDs will start to flash

yellow-red. This starts FACTORY MODE!

To calibrate 4-20 mA input signal

• Apply 4.0 mA input signal and then push

the button three (3) times until all LEDs

are lighted. The LEDs will now start flash

yellow-red again.

Apply 20.0 mA input signal and then push

the button three (3) times until all LEDs

are lighted.

To calibrate 4-20 mA transmitter

output signal

Note! If no transmitter board is installed

the LEDs will start flash yellow-yellow and

the unit is ready for continued calibration.

If there is a transmitter board installed

the LEDs will start flash yellow-green.

The feedback transmitter output signal

on pin 9 and 10 will now follow the input

signal instead of the position. Apply 4.0

mA input signal. Measure the output sig-

nal and adjust the input signal up/down

until the output signal is 4.0 mA. Push

the button three times until all LEDs are

lighted. The unit will now start to flash

yellow-green again.

The output signal on pin 9 and 10 will

continue to follow the input signal instead

of the position. Apply 20.0 mA input sig-

nal. Measure the output signal and adjust

the input signal up/down until the output

signal is 20.0 mA. Push the button three

times until all LEDs are lighted.

The LEDs will start flash yellow-yellow

and the unit is ready for continued

calibration.

Press the button for 5 sec until the LEDs

start alternating, D20 starts to calibrate

stroke.

After calibration the unit will start running

in normal operation.
