Carefully read the operating instructions before you put pressure
monitor into operation. In case of damages arising from non-observance
of these instructions, from improper handling or treatment, or due
to wrongful use, warranty claims are forfeited. We do not assume any
liability whatsoever for consequential damages resulting thereof.
Installation and dismounting of this device must be performed by
qualified personnel. The applicable country-specific harmonised safety
regulations for the operation of pressure measuring instruments must
be observed. Respective device-specific requirements concerning
protection type must be assured in built-in condition.
CALIBRATION
Please note: Only versions showing a 1 in the fifth digit of the product
number behind the dot (692.XXXX1XXXX) can be calibrated.
FACTORY SETTING
Pressure 0, output signal 0 respectively 4 mA, or 15 - 25 mV
(20 mV typically) in case of voltage output.
Maximum pressure = maximum output signal.
CALIBRATING POSSIBILITIES
Zero point
by potentiometer, lacquer sealed
white
(Fig. 2)
At pressure 0, the output signal can be ad 10 % FS.
At pressure 10 % FS ± 10 %, however in case of 0 - 10 V
not less than 20 mV typically.
Rate-of-rise
by potentiometer, lacquer sealed
red
(Fig. 2).
± 10 % of the effective output signal can be adjusted under
corresponding pressurization.
CALIBRATING PROCEDURE
– Make electric connections in accordance with diagrams Fig 1.
– Loosen 4 plug connector fastening screws,
pull-off plug to make potentiometers accessible.
– For class 0.6 pressure controllers or better,
connect lower pressure at P2, and higher pressure at P1.
– Adjust zero point output signal at zero point potentiometer
(lacquer sealed white, Fig. 2).
– Apply desired higher pressure and adjust output signal at
rate-of-rise potentiometer (lacquer sealed red, Fig. 2).
– Repeat this process two to three times until values lie within
the tolerance range.
– Lacquer-seal all potentiometers again after calibration.
Close electrical connection part tightly.
Note!
GND and housing
are only capacitively
and not galvanically
connected.
