mA wiring input

Open collector outputs

• The 6 open collector outputs can be programmed to suit your application in process control.
• Currently, three collector outputs have been used. As a standard, these are set to be sourced outputs (positive logic).
• Pre-wiring all these outputs will give the following schedule:

Below is a description of each open collector:

• SG value is lower than the low alarm value
• This open collector output will give a positive constant voltage when the SG is lower than the low alarm level. This voltage can be used to switch a relay contact that switches a valve or pump.
• The output can be powered by the internal power on the main board. Add a second fuse after the power converter to the 24Vdc connector on the left bottom and wire this to the below-mentioned terminals on top of the HMI.

SG value is higher than the high alarm level

• The open collector output #3 will give a positive constant voltage when the SG is higher than the high alarm level. This voltage can be used to switch a relay contact that switches a valve or pump.
• The output can be powered by the internal power on the main board. Add a second fuse after the power converter to the 24Vdc connector on the left bottom and wire this to the below-mentioned terminals on top of the HMI.

Solids Production pulse

• This open collector output will give a positive pulse when 1-ton solids are produced.
• This is only the case when the production shift is started.
• When the production shift is started and the analyzer is restarted, the shift is started again, but the totals are reset to 0.
• The output can be powered by the internal power on the main board. Add a second fuse after the power converter to the 24Vdc connector on the left bottom and wire this to the below-mentioned terminals on top of the HMI.
• Set the pulse duration in steps of 10 ms in the IO Module settings, Digital IN/OUT.

Analyzer fault

• This open collector output will give a positive constant voltage when the analyzer is in fault mode. A fault mode is triggered when a measurement is not possible anymore. In general, this is the case when the analyzer cannot communicate with the transmitters.
• This voltage can be used to switch a relay contact that switches a valve or pump.
• The output can be powered by the internal power on the main board. Add a second fuse after the power converter to the 24Vdc connector on the left bottom and wire this to the below-mentioned terminals on top of the HMI.

Open collector inputs

• The 6 open collector inputs can be programmed to suit your application in process control. Currently, one collector input is used. As a standard, these are set to be sourced inputs (positive logic). Pre-wiring all these outputs will give the following schedule:

process by pressing this button for 0,5-9 secs. After 10 seconds, you can press again to indicate that sampling stopped. The logging file contains of ID of the sample.

Spool piece/wafer Installation

Mounting position

• In the vertical pipe, mounting position is not relevant
• In the horizontal pipe, a mounting position must be as in the picture:

mounting location

• a. Mounting 7x diameter after last obstruction and 5x diameter before next obstruction (pump, bend, narrowing, valve)

Startup

• Start-up and commissioning by unauthorized personnel is at their own risk.
• During start-up, when the mA outputs are not connected, an error code is shown. Simply press the X to remove the error and it won’t show up anymore.

Correcting mA outputs

• a) The mA output of the SG and the Density is not the same. To get these the same, follow the below instructions.
• b) Press the SG box in the above picture, and the following menu will open with a prompt for a level 2 User ID and Password code in order to gain access.
• c ) A tap on the User ID block will open the keypad. Type EL as the user ID and press enter.
• d) The keypad will open again for the password. Type 07AF as the password and press enter, which will then take you back to the level 2 menu as above, but now indicating both the user ID (EL) and the password as.
• e) Press OK, which will then open the Field Calibration menu below. Press > to go to the DO and AO settings:
• f) Note that the range of 4-20 mA for the SG is here: 1..2 SG. And that the current mA output is 14,60. Now, go back to the main screen:
• g) Press DENSITY
• h) Make sure all settings are as above. Then Press > to go to the following screen.
• i) The 4-20 mA value is 17,24 because the range is here 1000..1800 (while SG was 1..2). Change as follows:
• j) Press save. The next screen will be shown:
