Retrofitting

The MAG-SM in a field mount housing or in a 19"-Design can
also be used to operate the electromagnetic flowmeter
primaries Model 10D1422. Only flowmeter sizes 1/10" to 40"
[DN 3 to DN 1000] can be retrofitted. The following

!
Note:
Select the flowmeter primary model number in the parameter
"Primary Type" in Submenu "Primary" in the converter. Switch
S901 on the connection board of the converter in the field
mount housing must be opened (see "Connection Board,
Field Mount Housing 50SM1000" on Page 38).

Interconnection Diagrams can be used for the converter
in a field mount housing or in a 19"-Design.
WARNING:
!
The magnet coils are supplied from the line,
not from the converter. It is essential that both
the flowmeter primary and the converter are
connected over a single mains switch and a
single mains fuse.
