3.4 INSTALLING TRANSMITTER SERIES CER-2000
The position of the electronic housing is depending on the welding position of the weld-on adaptor. Before
welding, locate the weld-on adaptor so that the cable entry and the venting are in the right direction.
DO NOT DAMAGE THE THREAD.
3.5 MOUNTING POSITION
When the transmitter is mounted horizontally, the cable gland must be pointed downwards.
3.6 MOUNTING POSITION EFFECT (Series 2000 and Series 2000-SAN)
All transmitters are calibrated in vertical position. If the transmitter is mounted in another position, there can
be a little zero shift. (4.02 mA instead of 4.00 mA). If the transmitter is mounted down, there is a zero shift
(For example 3.98 mA instead of 4.00 mA). After installation of the transmitter the zero must be set to 4.00
mA with P103 in the programming mode. This will not affect the span.
3.7 INSTALLING TRANSMITTER SERIES 2000-Hydrobar
The diaphragms are protected by a special protection cap (PE). Do not remove this cap. When clogging is a
problem, please contact Klay Instruments. Do not damage the diaphragm.
3.8 CALIBRATION
All transmitters are fully calibrated at the factory, to customer specified range. If calibration is not specified,
the transmitter will be calibrated at the maximum span.
3.9 WIRING
Under the cover (3) you will find the terminal board.
The push buttons "Zero", "Span" and "Prog" are
under the other cover (1). External loads must be
placed in the negative side of the 2-wire loop.
The figure left shows the wiring connection of the
transmitter. The 2-wires must be connected to 3 (-)
and 4 (+) of the terminal board.
The screw terminal tightening torque range needs to be: minimum 1.0 Nm (8.85 in-lb); max. 1,2 Nm
(10.62 in-lb).
Remove approx. 5 cm (2 in) of the cable mantle, strip approx. 1 cm (0.4 in) of insulation from the ends
of the individual wires. When using stranded cable apply the correct end sleeves for the wires and
make sure these are connected properly underneath the screw terminals.
The field wire conductor cross-section needs to be: minimum 0,2 mm2(24 AWG) and maximum 1,5
mm2(16 AWG). The transmitter must always be connected to
earth. The transmitter must be connected with
standard two-wire shielded cable. Do not run signal
wiring in open trays with power wiring, or near heavy
electrical equipment (Frequency controller or heavy
pumps). Shielding must always be connected at the
side of the power supply. In case the process
connection is already connected to ground (e.g. via
the tank or pipe line) Do not connect the instrument
to ground. Please ensure that the instrument is
not connected to ground twice to prevent an
'earth loop'. In applications with synthetic process
connections, the enclosure (internal or external)
must be connected to ground.
The CER-2000 with a synthetic process connection must be
connected to earth. Reversing the polarity will not damage the
transmitter, but the transmitter will not function
until the + and –are properly connected.
