Trouble Shooting

Caution!
If the MAS 2600 transmitter is not functioning in accordance with Marine Tank Management instruc-
tions, check that:
1. the 24 VDC power supply has been correctly connected, and is between 17-33 VDC.
2. the 4 - 20 mA output signal is functioning (compared with e.g. hand sounding).
3. the transducer cable has been correctly fitted and the shield connected to the shield terminal in
the amplifier box.
4. the diaphragm has not been damaged.
If this does not succeed, fill in the test sheet on page 46 and submit this to our Service department at
Marine Tank Management.
When contacting our Service department please specify the serial numbers of transducer, amplifier
and box.
The test sheet will be examined to see whether it can be established that the transmitter is broken or
not.
When returning a defective MAS 2600 transmitter, please ensure that:
• The transducer diaphragm is protected against mechanical damage.
• Both the transducer and the amplifier are returned.
• A detailed description of the fault is enclosed.
Please observe that testing and recalibration of transmitters mounted in hazardous
areas shall be carried out by Ex qualified personnel.
