Core security standards

4.1 Electrical Safety (Warning Level)

Power requirements

Designated power cords must be used, with voltage matching the rated value of the instrument (100-240VAC). Exceeding the maximum voltage of the power cord (such as UL/CSA 125V, VDE 250V) is prohibited

The power plug must be inserted into a three core socket with protective grounding, and the use of ungrounded extension cords is prohibited

grounding protection

Before starting up, it is necessary to connect the protective ground and it is forbidden to cut off the internal/external grounding wire

Check if the grounding and fuse are intact. Do not operate if they are damaged

Operation taboos

Prohibited for use in explosive gas/vapor environments

It is prohibited to dismantle the casing (including high-voltage components inside) without authorization. Only qualified personnel from Yokogawa can repair it

Before connecting external equipment, it is necessary to ground it first. Before touching the circuit, turn off the power and confirm that there is no voltage

4.2 Laser Safety

Laser classification and standards

Module model: Laser classification meets key protection standards

AQ2200-112/131/132 Class 1 IEC 60825-1:2014, 21 CFR 1040.10/11 prohibits direct viewing of laser beams

AQ2200-111/141/142/136 Class 1M IEC 60825-1:2007, 21 CFR 1040.10/11 prohibits the use of optical instruments (magnifying glasses, etc.) for observation at<100mm

Laser unlocking process

Connect the included interlock plug (A1288JA) to the Remote INTERLOCK interface behind the frame controller

Press the SYSTEM key to enter the system screen, move the cursor to Lock, and press ENTER

Enter the default password ‘1234’ and press ENTER

Set Lock to Off and press OK to confirm (laser output can only be turned on after unlocking)

4.3 Environmental Protection and Compliance

WEEE Directive (EEA and UK): Prohibition of mixing household waste, contact local Yokogawa office for disposal

Battery Directive (EEA and UK): Lithium batteries must be collected separately and replaced. Contact the local Yokogawa office for replacement

RoHS compliance: The instrument itself complies with EU RoHS, but if incompatible modules (such as AQ2200-111, AQ2200-131, etc.) are installed, it becomes invalid. The list of incompatible modules can be found in Section 5.1

Operation process guide

5.1 Module installation and uninstallation

Installation steps

If there is a blank panel in the slot, loosen the screw → slide down to remove the panel

Press the unlock button on the module panel and lift the locking lever

Align with the slot guide rail and slowly insert the module until it is fully seated

Slowly press the lever until you hear a “click” sound (2/3 slot module needs to tighten the bottom fixing screw)

Uninstalling steps

If it is a 2/3 slot module, first loosen the bottom fixing screw

Press the unlock button and gently lift the lever to unlock

Slowly pull out the module (protrude about 1cm, then pull it out by hand)

Hot swappable instructions: Modules can be installed/uninstalled while the frame controller is turned on. If a non SUMMAY/DETAIL screen is displayed during uninstallation, it will automatically switch to these two screens

5.2 Cable Connection

Fiber optic connection

Cleaning the fiber optic end face: Soak the cleaning paper in isopropanol, press and rotate the end face to wipe, then dry it with dry cleaning paper, and finally blow away residual dust with compressed air

Connection rule: The ANGLED PC ONLY interface is only connected to APC type fiber optic cables and is prohibited from connecting other types (to avoid damaging the plug)

Connector adapter: such as AQ9441 (for FP-LD module), AQ9335C (for sensor module), align the guide pin/hole connection according to the manual steps, and lock the lever

electrical connection

Coaxial cable: used for modules such as BERT and optical modulators. Before connecting, confirm that the signal output is turned off and tighten the connector with a torque of 0.9N-m

Power cord: Confirm that the instrument switch is turned off, connect it to a three pin grounded socket, and ensure that the voltage matches the rated value

Key module connection example (BER test)

BERT module (AQ2200-601) DATA OUT → Optical modulator (AQ2200-621/622) DATA IN

Light modulator LD IN → Light source module (AQ2200-111 PMF type) laser output

Optical modulator OPT OUT → DUT → Optical receiver (AQ2200-631) OPT IN

Optical receiver DATA OUT → BERT module DATA IN 1 (CDR)

5.3 Startup and Screen Operation

boot process

Confirm that the power connection is correct, press the POWER switch on the front panel of the frame controller

The instrument automatically performs self check, and after passing the test, it displays the SUMMAY screen (global module information) or Detail screen (individual module details)

Preheating requirement: To ensure measurement accuracy, it is recommended to preheat for at least 1 hour after turning on the machine

screen operation

SUMMAY screen: The blue background represents the “current module” (modifiable parameters), the light blue background represents the “current parameters”, and the empty slot displays “NO MODULE”

Detail screen: The top displays the current module slot, allowing you to view/modify all parameters of the module (such as wavelength and attenuation values)

Hard key function (key buttons)

Hard key function keyboard mode corresponds to numbers

Switch to Detail Screen 7

SLOT ◄/► Switch current control module 8/9

Switch to SUMMAY screen 4

HOLD pauses screen updates, press again to resume 5

SYSTEM: Enter the system settings screen (date, password, etc.) 3

Maintenance and troubleshooting

6.1 Daily Maintenance

Cleaning requirements

Body: Wipe with a dry soft cloth after power failure. Do not use chemicals such as benzene or diluents (to avoid discoloration/deformation)

Optical interface: Clean with isopropanol and cleaning paper, and only use compressed air to remove dust from the sensitive surface of the sensor head (wiping is prohibited)

Electrical interface: Use compressed air to blow away dust, without using interface cover protective cap/terminal

Regularly replace parts

Suggested replacement cycle note for part name

Cooling fan for 40000 hours to ensure ventilation and avoid internal overheating

Lithium batteries will also be consumed even when the instrument is powered off for 3 years

ATTN module shutter 150000 times suitable for AQ2200-311/311A/312/331/332

LCD backlight for 30000 hours (default brightness 5) needs to be replaced when the brightness drops to half

Calibration requirements

Conventional module: It is recommended to calibrate once a year

AQ2200-111 (DFB-LD): Calibrate every 6 months due to semiconductor characteristics

Calibration method: Contact the Yokogawa dealer to adjust the parameters simultaneously

6.2 Troubleshooting

Common Problems and Solutions

Possible causes and solutions for the problem phenomenon

The instrument cannot be turned on. The power cord is not properly connected and the voltage does not match. Check the power cord connection and confirm that the voltage is between 90-264VAC

Laser lock without output, interlock plug not connected, unlock according to the process (password 1234)

PPG-ED cannot synchronize. The cable is not properly connected and the PPG and ED parameters do not match. Check the cable and confirm that the pattern and PRBS length of PPG and ED are consistent

OE displays LOS alarm for fiber not connected and low input power. Check the fiber connection and add an optical amplifier to increase power
