D000030108 en m – E650 Series 3 – ZMD300AT/CT – User Manual
The meters ZMD310xT can be ordered with a feature which detects strong
DC magnetic fields. When a magnetic field is present, event 134 is set;
when the magnetic field disappears, event 188 is set. These events can
e.g. be entered into the event log with date and time. The meter's type
description informs you whether this feature has been implemented (see
page 10).
With the DC magnet detection, it is possible to order the integrated terminal
cover detection option.
Installed ZMD300 meters can be equipped with a terminal cover detection
unit. For this, they need to be parameterised and the unit – consisting of a
switch which detects the removal of the terminal cover – has to be installed.
Whenever the retrofit terminal cover is removed, it detects the switch status
change via control input 1 and enters event 211 in the event log with date
and time. When the terminal cover is mounted again, event 212 is entered
in the event log with date and time.

the terminal cover is removed and event 187 when the terminal cover is
