30 VEGASWING 81A and 83A
b.Current value > 22 mA
- Check all connections and the connection cable to the sensor .
- Should the red failure lamp still light, separate the sensor from the
connection line and connect a resistor of 1 kW instead.
If the failure lamp goes out, the sensor is defective. Check the con-
nected sensor.
- Should the failur e lamp still light, r econnect the sensor. Separate the
signal conditioning instrument from the connection cable and connect
a resistor of 1 kW to the sensor input.
- If the failure lamp still lights, the signal conditioning instrument is de-
fective. In this case r eturn the instrument to VEGA for r epair.
- If the failure lamp goes out, there is probably a short-circuit in the
connection cable. Check the connection cable to the sensor .
Malfunction during After pushing the test key , the switching conditions do not occur in the
function test correct sequence or for the correct period, e.g. there is no full signal
provided.
- Measure cable resistance
When the line is high-resistance, you must take appropriate meas-
ures to reach a standard resistance. E.g. check the terminals and
cable connections for corrosion.
