T/S-REC-04


Root Cause: HiSCM card malfunction

Trouble Shooting: Check LED status of HiSCM card

1. Check LED status of HiSCM card.

2. HiSCM card has 8 channels for interfacing

with 3rd party system. Recitifers are

connected with each channelr. Below

photo is just for reference.

Please find channel information from final

drawing.

3. If LED Status of channel is OFF or Steady

(not flickering), reset HiSCM according to

procedure No.4.

If LED flickered with Green color, HiSCM is

in normal status but data is not coming

from rectifier.

In this case please investigate rectifier

side.

If LED flickered with Blue color,

communication is working well with

rectifier.

4. Push side button of HiSCM card

5. Pull HiSCM card out.

6. Mount securely again.

T/S-REC-05

Alarm Tag.: [REC1(2/3/4)002]

Root Cause: External emergency stop

Trouble Shooting: Reset rectifier

1. External emergnecy stop(Error code A16)

is come from outside of rectifier.

Remove emergency stop condition first,

then reset rectifier.

2. Click Reset button on rectifier MIMIC.

- 122 -

3. Click Reset button on MIMIC.

T/S-REC-06

Alarm Tag.: [RF-A/B/C/D-1007]

Root Cause: Loosen of output cable connection, PCB malfunction

Trouble Shooting: Check output cable, compare actual value and MIMIC value

1. Check power cable connection. If loosed,

tighten it.(Before tightening, cut the power.)

2. During ballasting operation, check actual

shunt value by using clamp meter.

3. Check MIMIC value on HMI.(Shunt #1,#2,#3 and #4)

- 124 -

4. Check shtun valve on MIMIC.

5. If there is big devaition between local and

MIMIC, PCB need to be replaced.

T/S-REC-07


Root Cause: Loosen of power feeder cable

Trouble Shooting: Check cable tightness of the power feeder.

1. Before cable connection check,

:cut the rectifier power.

2. If there is loosed connection, tight it.

T/S-REC-08


Root Cause: Mis-arrangement of manual valve.

Trouble Shooting: Check the manual valve of electrolyzer outlet is open.

1. Check electrolyzer outlet valve is open.

(Default open)

T/S-REC-09

Alarm Tag.: [RF-A(/B/C/D)-1004] / [REC-1(2/3/4)004] /

[RF-A(/B/C/D)-1007] / [REC-1(2/3/4)007]

Root Cause: Electrolyzer scale formation

Trouble Shooting: Acid cleaning of electrolyzer

1. Preparation

1) Circulation pump(Flow-rate 20m3/hr)

2) 200L Drum

3) Acid Chemical(Prepare one of below

chemical)

HCl(Hydrochloric Acid) 1% density

SAF-ACID 7% density

DESCALEX 4% density

4) Hose, Flange fitting

2. Drain electrolyzer unit by opening drain

valve(Tag No. DV-1111, DV-1121)

3. Close electrolyzer inlet valve(Tag No. XV-1121) and outlet valve(Tag No. MV-1111) to isolate.

MV-1111

XV-1121

- 128 -

4. For cleaning module A, please close outlet valve of module B (Tag no. : MV-1113B) and C

(Tag no. : MV-1113C).

If you want clean module B, close outlet valve of module A (Tag no. : MV-1113A) and C (Tag

no. : MV-1113C).

5. Prepare 200L drum and dilute Acid

chemical with fresh-water.

HCl(Hydrochloric Acid) 1% density

SAF-ACID 7% density

DESCALEX 4% density

MV-1113C MV-1113B MV-1113A

- 129 -

6. Prepare circulation pump and hose, connect to maintenance flange like below.

- 130 -

7. Circulate the acid solution by using

cirulation pump for 2hours. And then check

pH. If pH is above 2, add 25%(vol.) of the

acid initial filling more.

8. Repeat step 7 two times more.

(Total acid cleaning time : 6 hours)

9. After cleaning, drain acid solution totally.

Then rinsing by fresh water circulation.

10. Arrange valve for normal operation.(Open

electrolyzer outlet valve and inlet valve.

Close drain valve)
