Polymer Electric

Troubleshooting and remedies

Fault display

Possible cause

Elimination

Green LED “POWER”
not lit

No or incorrect supply voltage

1. Check the supply voltage: Does it

comply with the type plate?

2. Check the PIN assignment

If supply voltage is correctly connected:
Evaluation Unit faulty

Replace the Evaluation Unit

LEDs lit or

ash ran-

domly

Supply voltage too low or incorrect

1. Check the supply voltage: Does it

comply with the type plate?

2. Check the PIN assignment

The green LED “Power”

ashes at 10 Hz

Interference in the direct vicinity of the
sensor (ultrasonic transducer)

1. When possible, eliminate the interfe-

rence

2. Recon

gure the sensor

3. Move the sensor

Internal error

Perform a RESET

The green LED “Power”

ashes at 20 Hz

Electromagnetic interference

1. Check the cable laying between the

sensor and the Evaluation Unit: Too
close to the source of interference?

2. Shield the USi from the source of

electromagnetic interference

3. Earth the Evaluation Unit

Acoustic interference

1. When possible, eliminate the interfe-

rence

2. Recon

gure the sensor

3. Move the sensor

Green LED “Power”

ashes at 2 Hz, yellow

LEDs “OUT 1.1” and
“OUT 1.2” are lit

Sensor

1 not correctly connected

Connect Sensor 1

Check the cable connections

If Sensor

1 is correctly connected: Supply

line or sensor faulty

Replace Sensor

Green LED “Power”

ashes at 2 Hz, yellow

LEDs “OUT 2.1” and
“OUT 2.2” are lit

Sensor

2 not correctly connected

Connect Sensor 2

Check the cable connections

If Sensor

2 is correctly connected: Supply

line or sensor faulty

Replace Sensor

Green LED “Power”

ashes at 2 Hz, all yel-

low LEDs “OUT” are lit

Sensor

1 and Sensor

2 not correctly con-

nected

Connect both sensors

Check the cable connections

If the sensors are correctly connected:
Supply line or sensor faulty

Replace both sensors

Prerequisite: The USi is connected to the supply voltage. There is at least one
sensor connected to the Evaluation Unit. Only taught-in objects are located in the
detection

eld.
