QX and SX recorders - Installation Instruction

Mother Board

QX Recorder

SX Recorder

This Installation Instruction sheet is intended as a guide for replacing or installing hardware and for setting up

functionality in the recorder. Refer to the User manual for detailed operational requirements.

The QX and SX recorders are designed for ease of assembly with minimal disturbance to the rest of the unit. If unsure,

please return the unit to your supplier for repair or upgrade.

Removing the case and opening the back of the recorder should only be performed under the following circumstances:

When an item of hardware requires individual replacement.

When an item of hardware is to be retrospectively fitted.

In all other instances it is recommended that the complete unit be returned to an authorised agent or service centre.

For Agency Approved recorders the product needs to be upgraded or repaired by an Authorized Repair facility

WARNING

HAZARDOUS VOLTAGES

Disconnect all power to the recorder before removing the case and attempting any maintenance procedures.

SAFETY TESTS

Upon completion of service procedures detailed in this manual two basic safety tests should be performed in order to

ensure continued safe operation of the instrument.

Earth Resistance; 25 VDC applied between case and protective earth, bonding resistance should be < 0.1 Ohm.

Insulation Resistance; 500Vdc applied between the earth terminal, and the live and neutral terminal shorted together,

insulation resistance to be >2.0 MOhm. (Mega Ohm, NOT milli Ohm)

Failure to comply with these instructions could result in death or serious injury

CAUTION

OBSERVE ANTI-STATIC PRECAUTIONS

Refer to BS EN61340-5-1: 2001. Basic specification. Protection of electrostatic sensitive devices.

Full anti-static precautions MUST be observed when in contact with the electronics of your recorder.

SAVE DATA, SETUPS AND LAYOUTS

Removal of PCBs and battery back-up will result in the loss of all non-volatile data.

Ensure all data and set-ups are saved.

Failure to comply with these instructions may result in product damage.

Before attempting to repair or upgrade a recorder, it is advisable to clear a sufficient work space so components such as

the front panel can be rested on the work surface without getting scratched or damaged.

Panel Mounting

To replace the Mother Board the recorder must be removed from the panel. To require the recorder from the panel,

loosen the mounting clamp screws, slide the clamp towards the rear of the recorder and remove the clamps and the

recorder.

Removing the Case

Removal of the entire case is necessary for replacement of the Mother Board.

Remove any connectors fitted in the rear of the recorder, including the CJC sensors. The case and back panel can be

removed as one assembly.

Remove the 4 screws (2 on each side of the case). Retain screws for re-fitting.

Figure 1 shows the SX recorder; figure 2 shows the QX recorder.

Slide the entire case off the back of the recorder.

Removal and re-fitting the Mother Board

Once the case is removed, loosen the screws that hold all the I/O boards and power supply into the case. Pull each of

these cards towards the rear of the recorder so that their connectors disengage from the Mother Board. (The mother

board stands vertically inside the recorder). The boards do not need to be completely removed to allow access to the

Mother Board.

Disconnect the speaker cable from the mother Board.

Once all cards have been disengaged the Mother Board can be pulled upwards to unplug from the processor board.

The Mother Board can now be removed.

Inserting a Mother Board

Inserting a new Mother Board is simply the reverse operation.

Drop the new Mother Board into the board guides and push it down until it is fully plugged into the processor

board.

Reconnect the speaker cable.

Carefully slide all the boards back into the recorder ensuring that the connectors mate correctly with the Mother

Board.

Tighten the screws that retain the boards.

Slide the case back over the recorder assembly, ensuring that the rear connectors are aligned with the slots in

the rear panel.

Refit the 4 screws that fix the case to the recorder.

QX torque setting should be 0.5 - 0.75Nm/4.4 - 6.6lbf-in

SX torque setting should be 0.5 - 0.70Nm/4.4 - 6.2lbf-in
