A = Sealing of the electronics compartment
B = Sealing of the connection housing (remote version) after installation
In collaboration with the standards authorities, Promag 51 instruments are sealed before delivery.
With the remote version, the connection between sensor and transmitter is to be sealed on site.
Setting-up custody transfer mode Deactivating custody transfer mode
1. Open the transmitter's electronics compartment
cover by loosening the corresponding sealing screws
(A).
2. First of all, configure all functions important for cus-
tody transfer mode, such as “PULSE CT TRANSFER”,
etc.
3. Now enter the custody transfer code “5100” in the
“CODE ENTRY” function. The device is then in cus-
tody transfer mode. “CUSTODY TRANSFER YES”
appears on the display.
This “fixes” and saves the custody transfer mode
internally in the measuring system.
"
Caution!
– In custody transfer mode, all functions relevant to
custody transfer are automatically locked. These
functions can not be changed later on sealed meas-
uring devices; they are marked in the “Description
of Device Functions” Manual with a key-hole
symbol (
`
).
– Additional particularities in custody transfer mode
are described on Page 73.
4. Tightly screw the electronics compartment cover
back onto the transmitter housing (for the compact
version also the retaining claw).
5. The measuring device now has to be sealed with the
sealing screws (A, B, see Fig. 41).
1. Switch the power supply off.
2. Break the leaded sealing (A) and open the transmit-
ter's electronics compartment cover by loosening
the sealing screws.
3. Remove the display module by pressing the side
latches and pull the S-DAT off the amplifier board

Page 96, 98.
4. Reinsert the display and close the electronics com-
partment cover onto the transmitter housing.
5. Restart the measuring system by switching on the
power supply:
– When started, the “CUSTODY TRANSFER NO”
message appears on the display. Custody transfer
mode is now deactivated. All functions in the
programming matrix are now accessible again.
– Now, the error message No. #031 “SENSOR HW-
DAT” (see Page 85) will appear because the
S-DAT is not connected. To remedy this, proceed
as follows.
6. Switch the power supply off again!
Now complete the following procedure:
– Remove electronics compartment cover
– Remove display module
– Put S-DAT back onto the amplifier board
→

– Reinsert display
– Mount electronics compartment cover back
onto the transmitter housing
– Switch power supply on
Normal operation in “non-custody transfer mode”
is now fully possible.
