7 Troubleshooting

7.1

Indicators at the SC2

The SC2 has got no diagnostic indications; they are only available on the basic sensor boards of SB, MSC,
MSB or MGC.

7.2

Indicators at the MC2

The 4 - 20 mA output of the MC2 can be used as diagnostic indicators.

Output current

Restart:

1 mA

Device error:

2 mA

Tolerable negative sensor drift:

3 - 4 mA

Normal measurement mode:

4 - 20 mA

Tolerable overrange:

20 - 21 mA

Overrange error:

> 21 mA

Maintenance message:

19 mA

7.3

Basic Sensor Board

Trouble

Cause

Solution

Green LED isn’t on.

Power voltage not applied.

Measure tension at X4:
(16-28 V DC) Pin 1 (+) and 2 (-)

Polarity not correct at X4.

Connect correctly.

Connector X4 not plugged in.

Check the plug.

Wire breakage

Check the wiring.

Green LED doesn’t flash.

BSB: no address

Check BSB address, address
correctly.

BSB: no field bus communication

Check field bus wiring, topology
and termination.

No measured value at the Tool or
Controller

SC not or wrongly plugged in.

Check SC plug.

SC not registered.

SC gas type/measuring range doesn’t
match with registered ones.

Check SC data<> registration
data for conformity.

Message at the Tool / Controller:
-  24 V DC voltage <range>
-  5 V DC voltage <range>
-  Temp. <range>
-  WatchDog triggered

Internal error

Replace BSB.

7.4
