Gesint RL User Manual

It is recommended to use a connection cable of at least 0,5mmq
section and a maximum length of 250mt. Connection cables must
have separate run from power cables.
If the reed probe is installed upside-down, that is with the output
connector near the minimum level, the connection polarity
(PIN 4 and 6) must be inverted to obtain an output matching the
level measured.
In order to use voltage output (0-10V) pin 7 and 8 must be
connected together.

RL
Level transmitter
for reed probe
RL transmitter convert the level measure from a
GSH reed probe and a magnetic float in a
4-20mA or 0-10Vdc analog output signal.
The output signal of the instruments is
proportional to the distance between minimum
and maximum point set during calibration.
The transmitter is supplied with 1 relay output
that can be used as level threshold or alarm.
Digital calibrations and settings with 2 push
buttons.
The warranty is valid for 12 months from purchase, and expires if instrument is improperly
used or not correctly installed on system.
Warranty
CE mark according to Directive 89/336/CEE, complies with the following harmonised
regulations: EN50081-1, EN 50082-2, EN55022, EN61000-4-2, EN61000-4-3,
