Trouble Shooting

Small problems sometimes can be solved locally with the help of the below tab of trouble shooting.

If you don’t succeed, contact us or your nearest distributor.

Symptom

LED Indication

Possible reasons of the

symptom

Actions

Green LED (PWR)

is always light off.

No voltage auxiliary power

supply to terminals 1-3

(see wiring diagram).

Give auxiliary voltage supply to

terminals 1-3.

Thyristor unit

doesn’t go in

conduction with

input signal.

Green LED (PWR)

light on and green

LED (ON) in off

condition.

No input signal.

Reversed polarities of input

signal.

Reset contact in open

condition (see wiring

diagram).

Provide to give input signal.

Reverse the input signal polarity.

Make link on reset terminals.

Load current flows

also with no input

signal.

Green LED (ON)

always in off

condition.

Short circuit on thyristor.

Wrong connection.

Substitute the thyristor. Check that

load is not in short circuit.
