Q. I have an Mi3COMME or MI3COMMPN that is not communicating properly.
A. Update with latest updater to be sure that firmware is loaded correct.
Q. Do any Mi3 versions of COMM or MCOMM have onboard datalogging?
A. No - this feature was deleted (hardware change) in 2019 (serial numbers starting 19.....), older units are working.
Q. I have an Mi3COMME. In the web browser the datalogging box graphic is visible but I cannot enable logging.
A. An update of the web browser to remove the datalogging setup is still pending.
Q. How to setup multiple heads on MI3 Comm Box in Profinet Configuration?
A. You need to assign the correct head number in Pyrometer Parameters section in TIA Portal
Q. Is Mi3 supplied with a calibration certificate?
A. Supplied from the factory, free of change the Final End Test Report data is embedded every RAYMI3COMM heads. You can view the data and print the report using DTMD v5.4.1 See Article Special Note: Using DTMD v6 you can see the test points but you cannot print a certificate. These are displayed in the read only parameter list.
Q. Is a MI3 head compatible with legacy MID Eletronic (metal box) or is Mi3 Communication Box compatible with MID head?
A. No. You need to exchange both
Q. What kind of material is the lens of MI3 LT?
A. It is silicon.
Q. I recently received Mi310LTS heads and have noticed strange behaviour. What can I do?
A. If the serial number is in the range 554... to 559.... Please navigate to this page and try the small TT updater program TT Updater
Q. Can the OEM version connect directly (not using a COMM box) to a PLC?
A. Theoretically yes. There are open sourced Arduino/Raspberry Pi based PLCs on the market that offer i2C connectivity (3.3V logic). OEMMi3 can work at this signal level. These are very new products with unknown market adoption. Traditional based PLC manufactures appear to offer I2C by using an additional interface device. In which case, one may as well use an Mi3COMM, or Mi3MCOMM with built-in industrial protocol.
Q. How to Unlock the locked MI3 COM Box?
A. The unit can be unlocked by pressing the "Page" button and the "ENT" button simultaneously for 3 seconds or alternatively by pressing the "ENT" button for 5 seconds.
Q. Is there a special Mi3COMM box that will allow easy exchange of a single head?
A. Yes, the FJFMi3COMM will automatically delete the head when disconnected and allow a new head to install as HEAD1. This is designed only for single head use.
Q. Does Mi3 with Profinet support "diagnostic data"?
A. No.
Q. Is the MI3 series compatible to connect to DTMD v6?
A. Yes, but from revision 6.1.
Q. How does the alarm relay operate with setpoints in a multi-head system?
A. Consider a scenario where the Tobj setpoint for Head 1 is set at 200 deg C and that of Head 2 is set at 220 deg C
Q. Will my MI3100 be damaged looking at an object 3000 Deg C/5432 Deg. Is there any stare effect?
A. No.
Q. Is there any "stare" effect with Mi3100 (reading remains high for a very short period after measuring a hot object for a long time)?
A. No.
Q. Is it possible to use DTMD v6 to drive a fixed value of mV or mA on the output?
A. This is not currently supported, please use v5.4.1 (Loop Maintenance mode).
Q. Can the Atex version be used in Zone 1
A. Yes - for further info see Mi3 Atex Info Page
Q. Unable to find On the menu box set-up On output 1 to select for T/C type
Their is no indication )only shows output of a factory default setting of 0 to 5 VDC
A. On the menu page box setup by pressing the down arrow until you see output 2 this will have a factory of 0 to 5 VDC
Press ENT > 0 to 5 VDC will shade out press the down arrow to you see disable
Press ENT>then scow down on the down arrow unit you see output 1 set to 0 to 5VDC
Press ENT> will shade out press the down arrow you will see T/C Selection
Press ENT = output 1 is set to T/C
Q. Is there an Mi3 replacement for an MID DOP head?
A. Yes, please check the FJP special 30:1 option. Remember that you will also need to replace the COMM box. You construct the specification in the same way you with any Mi3 head:
FJP Mi3 30 LT SF (but also available in CF1 and CF2 like TX) plus CB3,8,15 (if you need >1m)
Q. Is it possible to have a PUR cable (shown in blue) longer than the default supplied 0.5m length?
A. Yes, the PUR cable can be extended utilizing a 4 core (not twisted pair) low capacitance shielded cable. Link to datasheets also provided below:
Mi3 PUR (blue) and PTFE (white) head cable data sheets : Fluke Process Instruments (freshdesk.com)
Q. What are the three calibration points used for RAYMI320LTS and RAYMI310LTS? Can the customer select customized three points?
A. There is a calibration certificate end test report embedded in each head. These are fixed ranges from production (automated calibration). If a regular calibration certificate is ordered (XXXMI3CERT), then these same points will be used. The calibration points are ambient,100 and 250 deg C. For specific points, an ISO certificate or a DaKKs certificate will need be ordered.
