In order to protect the diaphragm, the pressure connection of the instrument IS-21-S, -F is
provided with a special protection cap.
nRemove this protection cap only just before installing the pressure transmitter
in order to prevent any damage to the diaphragm.
nMount the protection cap when removing and transporting the instrument.

Diaphragm test for your safety
It is necessary that before starting the pressure transmitter you test the diaphragm, as this is
a safety-relevant component.
n Pay attention to any liquid leaking out, for this points to a diaphragm damage
(not necessary for IS-20-H).
n Check the diaphragm visually for any damage.
n Use the pressure transmitter only if the diaphragm is undamaged.
n Use the pressure transmitter only if it is in a faultless condition as far as the
safety-relevant features are concerned.
nRemove the protection cap only just before installation and absolutely avoid
any damage to the diaphragm during installation as well.
nEnsure that the cable diameter you select fits to the cable gland of the
connector. Ensure that the cable gland of the mounted connector is positioned
correctly and that the sealings are available and undamaged. Tighten the
threaded connection and check the correct position of the sealings in order to
ensure the ingress protection.
nWhen mounting the instrument, ensure that the sealing faces of the instrument
and the measuring point are clean and undamaged.
nScrew in or unscrew the instrument only via the flats using a suitable tool and
and the prescribed torque. Do not use the case as working surface for
screwing in or unscrewing the instrument.
nWhen screwing the transmitter in, ensure that the threads are not jammed.
For Model IS-20-S/-F the sealing ring is available as an optional extra. For Model IS-21-S/-F
the sealing ring is included in delivery.

accordance with the pin-assignment drawing.
7. Press the terminal block (6) back into the angle housing (5).
8. Tighten the cable gland (2) around the cable. Make sure that the sealing isnt
damaged and that the cable gland and seals are assembled correctly in order
to ensure ingress protection.
9. Place the flat, square gasket over the connection pins on the top of the instrument housing.
10. Slide the terminal block (6) onto the connection pins.
11. Secure the angle housing (5) and terminal block (6) to the instrument with the

n Open pressure connections only after the system is without pressure!
n Observe the ambient and working conditions outlined in section 7 Technical
data.
n Please make sure that the pressure transmitter is only used within overload
threshold limit at all times!
When touching the pressure transmitter, keep in mind that the surfaces of the
instrument components might get hot during operation.
The output signal must be proportional to the pressure. If not, this might point to
a damage of the diaphragm. In that case refer to chapter 9 Troubleshooting.
