PV624 Portable hybrid pressure controller

We currently have Genii DPI620G units which we are regularly seeing CJ temperature As Found results out of specification @±0.2°C. We have to raise a deviation investigation into each and every failure because these units are calibration standards and have been found to be out of specification against the published Technical Data
Datasheet.

However, the ±0.2°C is only quoted in the documentation as an uncertainty specification and we are enquiring whether this is a realistic specification when accounting for annual drift between calibrations.

Yes, it’s at the Software Revision DK420 V03.20.01
The list is the same for the DPI620G / DPI620G-IS as the FF device list is part of the Main Application DK420.

The Foundation Fieldbus and Profibus DD Libraries are part of the instruments Main Application (software DK0420). Upgrading to the latest version of DPI 620 Genii software
will ensure you have the latest DD Libraries.

The DD’s on the manufacturers website are not in the correct format for the DPI 620G therefore cannot be directly added.
If there are any DD’s that are not in the current library then the you will need to provide us with the DD for us to format, we can then supply the procedure to add it to the
library

It is possible to upgrade Genii Lites to have HART and FF communication.
The instruments will require returning to the factory for reprogramming, the FF option also requires some hardware adding and the FF Licence Installing.
The instrument label will also require updating to reflect the model change.

Our Customer Care team can provide you with a price for the upgrade.

Using the internal supply of the Genii-IS to power the current source you would be limited to a maximum resistance of around 525 ohms at 24 mA.

If the PM620 is working, but isn’t been recognized by the DPI620GENII-IS when connected to the pressure base.

Then this could be due to signal or 5Vdc missing from the
terminal. Check across the terminals for signals, power the DPI620GENII-IS on and you can then measure the 5V dc at the two outer terminals. With instrument switched off you should see between the two middle terminals resistance approximately 9.36K ohms.
If no voltage or resistance then it could be that either base or digital board that is faulty and would need further investigation.

The glass is part of the touchscreen, therefore the touchscreen will have to be replaced.
The part number for the touchscreen is IS620-7.

It is possible to copy the cal data over so long as you can retrieve the cal data from the old digital board.
The procedure is described below:-
Note – It will be easier to follow the procedure if you plug a mouse into the Genii’s USB port.
From the Dashboard select the Applications icon, then select the Desktop icon.
From the Desktop select My Device -> MMC Memory -> AMC -> CFiles
Copy the following files to the instruments SD card (My Device -> SD Memory).
User Settings
Config
In turn delete each of the above files from the Digital Board and then copy the old file from the SD card to the CFiles Folder.
Once completed all ranges should display in white digits, any ranges showing blue digits will indicate an un-calibrated range.
Carryout a calibration verification to confirm that the data has been successfully transferred.
If you need to re-enter the serial number then from the menu select Calibration and enter the pin 1129, the serial number can then be entered.

The error message is likely to be caused by a hardware issue.
The instrument will need to be returned for investigation/repair

The HART Library needs to be installed on the instruments SD card and not the internal memory.
There are two methods to upgrade the HART Library:-

1. Using the upgrade procedure in the User Manual K0541 Issue 2 – First ensure that the instruments USB Client Port is set to Storage Mode. Access the USB CLIENT PORT setting
as shown below and ensure that the USB CLIENT PORT is set to Storage mode and not Communications.
Connect the USB lead from the PC to the Mini Type B USB port on the instrument.
The Internal SD card should then be seen on the PC as a removable disk.
The HART Library zip file can then be extracted to the SD card.
2. An alternative method to upgrade the HART Library would be to remove the battery from the instrument and then remove the SD card from its carrier within the battery
compartment. Plug the SD card into the PC or a card reader. Extract the HART Library zip file to the PC and then copy the HCF folder to the SD card (Note – remove the existing
HCF folder first).

Refit the SD card to its carrier and then re-fit the battery to the instrument. On power up the revision of HART Library should be shown in the Software Status menu.
