Installation And Commissioning; Current Output; Service And Maintenance - MANFRED JÜNEMANN ME10 Instructions D'utilisation

1.0 Installation and Commissioning

The pressure tapping points should be prepared in accordance with the indications given for the sok-
kets. For more details, see e.g. regulation VDE/VDI 3511 and 3512, sheet 3, also DIN 837-1/2.
Suitable for sealing are sealing washers to DIN 16258. The correct tighening torque is depending
on material and shape of the used seal. It shold not exceed 80 Nm. The mounting position should
not be subject to strong vibration and radiation heat.
The transmitters with digital display are immediately ready for service after the pressure and
electrical connections have
been made.
2.0 Wiring
Electrical connection is made by shielded cable and means of the cable box. Precise wiring
schemes can be seen in the drawings. In addition, wiring details and required power supply are
given on the rating plate.
Significance of applied terminal designations:
Ub+ / OV supply voltage
S+ / S- output signal
Protection / PE cable shield

2.1 Current output

Output signal 0 ... 20 mA / 3 wire-system (LED/LCD)
4 ... 20 mA / 3 wire-system (LED/LCD) / 2 wire system (LCD)
Power supply Ub = 17 ... 30 V DC
Admissible load Ra = (Ub - 17 V) / 20 mA
If current output not used, please connect terminal 2 and 3.
Output signal 0 ... 10 V / 3 wire-system
Power supply Ub = 17 ... 30 V DC (LED/LCD)
Admissible load Ra ≥ 10 kΩ

3.0 Service and Maintenance

The transmitter with digital display described hereunder is maintenance free. It incorporates no
components which have to be repaired or replaced on the site. Repairs will exclusively be carried
out at the factory.
Depending on working conditions, the pressure transmiter should be checked about once a year
to ensure that they are within their specifications and be adjusted if necessary. The calibration
procedure is as follows:
- As reference for checking and adjusting the measuring span, an adequately accurate pressure
standard is required.
- For readjustment, loosen, with a left-hand rotation, the cam ring (bayonet type), and remove
from casing with the window.
- Set zero point via potentiometer „ZERO".
- Set span via potentiometer „SPAN".
- After having carried out service and maintenance work, lock tightly the instrument with the cam
ring (bayonet type), the window and the sealing.
Quality for the
future
