Codings
Current outputs active or passive:
For instrument versions CPM153-xxA/Bxx (2 current outputs) and CPM153-xxC/Dxx
(2 current outputs with HART) the current outputs can be operated as active or passive.
Jumpers on the controller module M3CH allow recoding.
For non-Ex instruments, these modules may be recoded to active outputs.
#
Warning!
Ex instruments must
not
be recoded. Doing so will cause loss of intrinsic safety!
8.5
Replacing the device fuses
8.5.1
For non-Ex devices
#
Warning!
Danger to personnel. Before replacing the fuse, make sure the device is voltage-free.
•
Position of the fuse holder: "A" in Fig. 29.
•
Use only a 5 x 20 mm fine-wire fuse with 3.15 mA, semi time-lag fuse. All other fuses
are not permitted.
"
Caution!
If the fuse should fail again, have the device checked.

Disposal
The Mycom S CPM 153 is a transmitter which contains electronic components and
PCBs and therefore must be disposed of as electronic refuse. Please keep to the local
regulations.
