5 ADJUST:?

Description:

This command is used to verify the success of the adjust.

The result consists in one of the following options:

• Unknown state (Result: 0)

The system is not able to interpret the question and has to be switched

OFF and ON again. The adjust must be repeated. This event however is

an exception.

• The nozzle unit is too far down (Result: 1)

You have to screw the adjust screw in the direction “Close”. An adjust is

required (or must be repeated).

• The adjust was successful (Result: 2)

The position of the nozzle insert relatively to the tappet is OK.

• The nozzle unit is too far up (Result: 3)

You have to screw the adjust screw in the direction “Open”. The adjust

must be performed (or repeated).

Example:

Input:

ADJUST:?

Result:

The system informs about the current nozzle position.

Return:

The nozzle is correctly adjusted. Adjust was successful.

6 ADJUST:START

Description:

Sending this command causes the adjust to be executed at once. This

procedure checks on the position of the nozzle insert with respect to the

tappet. It is required during each initial start-up and after replacing the

nozzle unit.

For further information read paragraph 8.2.3, page 123.

Example:

Input:

ADJUST:START

Result:

The adjust is initiated.

Return:

Release NU Attention Fluid!!!!!

7 ADJUST:TO:CHANGE:<adjust range>

Description:

This command changes the size of the adjust range, where you can confirm

an adjust. The value entered is ten times the value in micrometers. E.g.

entering 142 will set the adjust range to 14.2 µm.

You can only enter values between 58 and 300 (i.e. 5.8 µm and 30.0 µm).

For further information read paragraph 14.8, page 174.

Important Note!

Widening the range too much can lead to a valve leaking even after the

adjust. Use the command carefully. It is mostly meant for applications

which use the fixed adjust.

Example:

Input:

ADJUST:TO:CHANGE:142

Result:

The adjust range is set to 14.2 µm.

Return:

8 ADJUST:VAL:FA:?

Description:

This command gives you the status of the fixed adjust. The two parameters

have the following meaning.

• Fixed adjust activated? (0 = FA off, 1 = FA on)

• Has valve been adjusted with a fixed adjust (0 = not

adjusted with fixed adjust, 1 = adjusted with fixed

adjust)

For further information read paragraph 7.12, page 76.

Example:

Input:

ADJUST:VAL:FA?

Result:

The command gives you the status of the fixed adjust (here:

fixed adjust is activated and the last adjust with this valve

has been performed as a fixed adjust).

Return:

1,1

9 ADJ:VALUES:?

Description:

This command gives you the parameters for the adjust range, where you

can confirm the adjust. The five parameters have the following meaning.

• Setting in regards to FA/FD (0 = normal, 1 = FA, 2 =

FA + FD, 3 = FD)

• Adjust values in µm (range 0 – 4 for normal adjust, 0 –

50 for fixed adjust, set during the adjust)

• Deviation from the adjust value in µm * 10 (e.g. 23 =

deviation by 2.3 µm)

• Range where the green adjust LED is ON in µm * 10

(e.g. 82 = 8.2 * 10, meaning a range from +/- 4.1 µm)

• LED status (1 = OFF, 2 = green, 3 = red)

For further information read paragraph 14.8, page 174.

Example:

Input:

ADJ:VALUES:?

Result:

The command gives you the adjust parameters.

Return:

2,45,23,142,2
