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 Indication 

on 

front unit 

Possible reasons of the 

symptom 

Actions 

 

Green LED is 

always light off. 

- 

No voltage auxiliary 

power supply to 

terminals 1-3 (see 

wiring diagram). 

- 

Give auxiliary voltage supply to 

terminals 1-3. 

Green LED (PW) 

light on and green 

LED (ON) in light 

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. 

 

 

 

 

Thyristor unit 

doesn’t go in 

conduction with 

input signal. 

Green LED (PW) in 

light on condition 

and green LED 

(ON) in light on 

condition. 

- 

Fuse failure. 

- 

Load failure. 

- 

Load connection 

interruption. 

- 

Thyristor faulty and 

always in open circuit. 

- 

With HB option the 

yellow led (HB) in light 

on condition. 

- 

Substitute the fuse. 

- 

Repair the load. 

- 

Provide to repair the wiring. 

 

- 

Substitute the faulty thyristor. 

 

 

- 

Check the load. 

 

 

Load current flows 

also with no input 

signal. 

Green LED (ON) 

always in light off 

condition. 

- 

Short circuit on 

thyristor. If there is HB 

circuit the red LED (SC) 

is light on. 

- 

Substitute the thyristor. Check 

that load is not in short circuit. 

Current flows at 

nominal value but 

yellow LED (HB) in 

light on condition. 

Yellow HB in light 

on condition. 

- 

HB circuit not tuned. 

 

 

- 

Current transformers 

not properly wired (if 

are external to 

CD3000). 

- 

Push CAL button in front unit to 

start HB calibration procedure. 

- 

Control current transformers 

wiring and Push CAL button in 

front unit to start HB calibration 

procedure. 

Red LED (SC) is 

lighted also if 

current is at 

nominal value. 

Red LED in light on 

condition. 

- 

HB circuit not properly 

tuned. 

- 

Push CAL button in front unit to 

start HB calibration procedure. 

Thyristor unit 

doesn’t work 

properly. 

 

- 

Wrong input signal 

selection. 

- 

Wrong input signal 

calibration (out of 

range). 

- 

Auxiliary voltage supply 

out of limits. 

- 

Control input signal setting. 

 

- 

Repeat input calibration 

procedure. 

 

- 

Verify the auxiliary voltage 

supply.
