Electromagnetic flowmeter 4 Electrical Installation

28 IM/WM–EN Rev. M

4.7.3 Configuration DIP Switches

Three configuration DIP switches are mounted on the transmitter backplane board.

These are factory set as follows:

 Remote transmitter – all OFF

 Integral transmitter – SW3 ON

For MID-compliant flowmeters set the read-only / MID protection switch to 'ON' to ensure the meter is

secure from tampering.

For HART software versions prior to 01.02.XX, this switch (set after commissioning) prevents login via the

keypad or bus at any security level.

From HART software version 01.03.XX onwards and for all PROFIBUS software versions, on MID meters,

all metrological-related parameters are locked and inaccessible at the Service level. Standard and

Advanced user level parameters can still be modified via the HMI or bus.

4.8 Refitting the Cartridge and Cover

Fig. 4.20 Configuration DIP Switches

Warning. Ensure the transmitter is isolated from power supplies before refitting the cover.

Caution.

 The communications bus type is HART FEX100 if not specified on the

cartridge label. An example of the PROFIBUS FEX100-DP variant cartridge

label is shown on the right.

 The cartridge communications type must match the the

communications type of the transmitter backplane pcb.

 To avoid damaging the cartridge during refitting, do not overtighten the cartridge screws.
