LEVELtrol-II Installation & Operating Instructions
Cause
4-20 mA Input current at
comp input smaller than
3.5 mA:
• Faulty Wiring
• Transmitter not set to "4-20
mA"
• Transmitter defective
Input current at RTD input
too low:
• Faulty wiring
• RTD defective
Calculated pulse frequency
too large:
• Pulse width setting too long
• Larger pulse scaler needed
Current input signal of the
level input exceeds 20.5 mA:
• Sensor overranged
• Incorrect full scale setting
of level sensor
• Function error in
transmitter or faulty wiring
Current input signal of the
compensation input exceeds
20.5 mA:
• Sensor overranged
• Incorrect full scale setting
of transmitter
• Function error in
transmitter or faulty wiring
Current input signal of the
level input is smaller than
3.5 mA:
• Level sensor not set to
4-20 mA
• Function error in
transmitter or faulty wiring
