7 Diagnostics

7.1 Simulation

To simulate a certain filling, you can call up

the function "Simulation“ on the adjustment

module MINICOM, in the software program

VVO or on the signal conditioning instrument.

You simulate a vessel filling and thereby a

certain sensor current. Please note that con-

nected instruments, such as e.g. a PLC,

react according to their adjustments and will

probably activate alarms or system func-

tions.

Simulation with VVO

If you start the simulation mode with the ad-

justment program VVO on the PC, the simu-

lated level is outputted until you quit the

simulation mode.

Simulation with MINICOM

If you start the simulation mode on the adjust-

ment module MINICOM, the sensor returns to

standard operating mode after one hour.

7.2 Error codes

Error codes Corrective measures

E013 No valid measured value Message is displayed during the warm-up

- Sensor in the warm-up phase phase

- Loss of the useful echo If the message remains, a false echo storage

(with the adjustment software on the PC - see

"Echo curve“ under "Sensor optimisation“) must

be carried out together with a modification of

mounting location and orientation to achieve the

lowest possible false echo background.

E017 Adjustment span too small Carry out a readjustment.

Make sure that the difference between

min. and max. adjustment is at least 10 mm .

E036 Sensor software does not run Sensor requires a software update (service).

Message appears during a software update.

E040 Hardware failure/Electronics defec- Check all connection cables.

tive Transducer defective.
