MOUNTING
Single rod (7MF - 7MH - 7MJ) / Single cable GWR probes
Shortening of probe length
Single rod/cable probes can be shortened safely in the field. Make sure to adapt the probe length/ 4-20 mA settings in the menu
and the re-install of a bottom spacer when applicable.
Single cable probes can be safely shortened in the field using below procedure. Make sure to adapt the probe length/ 4-20 mA
settings in the menu.
7M1/7M2 probe can be shortened in
field.
a. raise TFE weight (1) exposing secur-
ing device (2)
b. loosen both #10-32 set screws (3)
using 2.5 mm (3/32") hex wrench
and remove securing device
c. cut and remove needed cable length
(4)
d. re-attach securing device (2) and
tighten screws
e. enter new probe length (cm or inch-
es) in software (See page 12, Item 9)

Overfill safe and Overfill proof
Eclipse 7EK GWR probes are "Overfill safe" in use and
"Overfill proof" certified.
1 1/2" or 2"
socket weld or
Overfill safe means that the unit is capable to measure up
NPT
to the process connection. Units with "non overfill safe"
probes use software to ignore level readings in the block-
ing distance or transitioning zone. When level rises too high
in this zone, the unit may consider the end of probe reflec-
tion as the real level and may report an empty vessel
instead of an overfilling vessel.
Overfill proof protection (such as WHG or VLAREM) cer-
tifies reliable operation when the transmitter is used as
overfill alarm but assumes that the installation is designed
in such way that the vessel/cage cannot overfill.
The 7EK probe is designed to replace without modification
top/bottom mounted displacer transmitters. The unit will
measure over the entire probe length and indicate for
20.5 mA above the highest measurable point and 3.8 below
the lowest measurable point.
