1. SAFETY

1.1 OVERVIEW

This equipment is designed to be connected to hazardous electric voltages. Ignoring the installation precautions and warnings can result in severe personal injury or equipment damage. The following are general guidelines that should be followed when installing, operating and servicing the RCEM.

• Qualified technicians who are familiar with the warnings and instructions of this manual

must perform all installation, maintenance and service.

• Always follow all local and plant safety procedures.

• The equipment covers should remain closed at all times during operation to ensure

safety of personnel. Only authorized personnel or technicians should be allowed to open and service the equipment.

• Cover #3 (PC Board Cover) may be removed if the operator needs access to the diode

waveform connectors. Use caution whenever the cover is removed.

• Only qualified technicians should perform Service. If use of an oscilloscope becomes

necessary during operation or servicing, either the scope must be floating or ungrounded, or differential probe(s) must be used. The equipment is isolated from the mains via the power transformers. If a grounded scope is used, a hazardous condition is created since current will flow through the probe to ground.

• Replace fuses with correct type, size and value. Refer to the servicing instructions or

spare parts list for more information on replacement fuses. Do not bypass the fuses or modify the electronics. Disconnect power to the system before replacing fuses. Failure to follow these instructions will result in intermittent operation and premature failure and will void the warranty.

• The equipment is not intrinsically safe. Do not place in explosive atmospheres.

• The Current Transducers are double insulated to protect the operator from possible

hazardous voltage potentials of the rectifier. The transducers are also protected from heat by a protective sheath.

• Make sure the transducer cables and interconnection cables are kept well away from

hazardous voltage potentials and heat sources inside the rectifier.

• Keep the electronics enclosure as far as possible away from the hazardous voltage

potentials of the rectifier.

• Use of the equipment in a manner not specified by the manufacturer can impair the

protection provided.

DynAmp does not assume liability for the customer’s failure to comply with the rules and requirements provided in this manual.

2. HANDLING AND STORAGE

DynAmp products are engineered and manufactured for use in industrial environments. However, they contain sensitive electronic and mechanical components which may be damaged and fail if not handled and stored properly. All products must be handled and stored with the same care as any precision measurement instrument. Severe bumps or jolts may damage internal parts and cause malfunction or premature failure. DynAmp products are designed and assembled with conformal coating, shock mounting, and environmental seals, when appropriate or when specified. However, this protection requires that the product must be properly installed and operational before the protection is fully functional. Therefore, adequate protection from humidity, shock, and temperature must be provided during handling and storage prior to installation.

The handling and storage of equipment must be sufficient to meet the storage temperature and humidity specifications of the product and to prevent any condensation or contact with water or any other liquid. The storage location and container or crate must provide adequate protection from precipitation (rain, snow, ice) and direct water contact. Adequate shelter must be provided to prevent the accumulation of precipitation (rain, snow, ice) and water which can lead to the deterioration or failure of shipping containers or crates and cause water ingress. Storage in coastal or industrial areas subject to salt-laden or corrosive air or areas of wind-driven sand or other abrasive dust must be adequate to prevent the deterioration or failure of shipping containers or crates and cause ingress. Frequent inspection of storage areas and storage containers or crates is required to ensure proper storage conditions are being maintained.

If the shipping container or crate is opened and/or the equipment is removed for inspection prior to installation, the equipment must be repackaged in the original undamaged container or crate in the same manner as it was shipped to prevent environmental damage or placed in a storage location that meets the required environmental and storage conditions.

General product storage temperature and humidity requirements:

Storage Temperature: -40 to 70°C

-40 to 158°F Storage Humidity: 85%, non-condensing

DynAmp, LLC does not assume liability for the customer’s failure to comply with handling and storage requirements.

3. DESCRIPTION

3.1 GENERAL

The DynAmp RECTIFIER MONITORING SYSTEM Model RCEM is designed for isolated measurement of device currents in multiple path power rectifiers.

Model RCEM is a monitoring system composed of a 120 Channel Data Acquisition Unit, a laptop computer, Flexible Current Sensors, and the interconnection cables.

A 240 Channel RCEM is also available. This system consists of two 120 Channel Data Acquisition Units, a laptop computer, LEM~flex Current Transducers, and interconnection cables.

3.2 DEFINITIONS

The following terms are used extensively in this manual:

Address

active electronics hardware

referred to as R or S in ANSI circuit diagrams

output signals.

3.3 DATA ACQUISITION UNIT

The Data Acquisition Unit contains the following elements:

1.) Analog Card Rack containing:

Installation, Operation and Service Manual RCEM

2.) Backplane

3.) Reset Sync Cards

4.) Integrator Cards

5.) Personal Daq/56 – USB Data Acquisition Module

6.) USB Extender Receiver

7.) Digital Interface Module

3.4 LAPTOP COMPUTER

The laptop computer is connected to the Data Acquisition Unit via the USB Extender Sender and RJ-45 cable. The laptop computer provides a means of displaying the rectifier data. It also allows access to the internal test signal generator. The data is displayed on a spreadsheet program.

3.5 FLEXIBLE CURRENT SENSORS

The 3.625 ID Flexible Current Sensor is the standard sensor supplied with the RCEM. Other Flexible Current Sensor sizes are available from DynAmp, if required. Presently they include inside diameter (I.D.) sizes of 1.000", 1.500", 2.750", 4.250", and 2.875” x 5.500” models. All Flexible Current Sensors have the same output, so they may be interchanged.

3.6 MAGNETIC FIELD STATEMENT

The magnetic field from a high current DC bus may damage or destroy the laptop computer hard disk drive, or floppy disks. To avoid damage the laptop and floppy disks should be kept as far from the DC bus as practicable. Protect floppy disks in a magnetic shielded case. This warning applies at all times.

The destructive effect of a magnetic field on a hard disk drive depends on the orientation of the laptop computer within the field, and the degree of magnetic shielding provided by the hard disk enclosure. Laptop computer and hard disk manufacturers do not provide specifications for maximum magnetic field outside the hard disk enclosure.

It is difficult to accurately specify a maximum safe Gauss level for laptop computer disk drives. Our best estimate is a maximum ambient magnetic field strength of 25 to 50 Gauss for safe laptop computer operation.

This manual provides recommended guidelines for use of the rectifier monitoring system. It is the sole responsibility of the customer to assure safety of equipment and personnel when using this product.

5. TECHNICAL DESCRIPTION

5.1 GENERAL

The Data Acquisition Unit (DAU) contains one analog card rack with backplane, reset sync cards, and integrator cards. The Data Acquisition Unit also contains the Personal Daq/56 USB Data Acquisition Module, the USB Extender Receiver, and two power supplies. The Personal Daq/56 accepts a maximum of 120 device data channels. The Data Acquisition Unit #2 in a 240 Channel system does not contain an USB Extender Receiver.

5.2 BASIC THEORY OF OPERATION

Each current sensor is associated with the measurement channel for a specific rectifier element. The signal from each current sensor is conducted to the DAU via an individual 2conductor cable and a wire pair within the interconnection cable.

The output from a current sensor is a voltage waveform corresponding to the instantaneous change of current in the rectifier device associated with that current sensor. Integrating the output signal of the current sensor returns it to the current waveform being conducted by the rectifier device. The current waveform is converted to a DC voltage proportional to the RMS value of the integrated signal.

The analog card rack contains multiplexer circuits to switch the DC voltage signals into the twenty analog input channels located in the Personal Daq/56. The digital I/O in the Personal Daq/56 controls the multiplexer. The multiplexing scheme can be described as a 6-leg by 20-channel matrix. One of six integrator channels ("legs") is addressed on all 20 integrator cards.

5.3 ANALOG CARD RACK

The analog card rack contains the following elements: one backplane, two reset sync cards, and twenty integrator cards. See Figure 5.1.

Installation, Operation and Service Manual RCEM

5.4 BACKPLANE

The digital interface circuits to/from the Personal Daq/56 are located on the Data Acquisition Unit backplane. The backplane also contains the reset sync cards connectors, the integrator card connectors, the signal input connectors from the current sensors, and the power circuits.

The backplane also contains the ac zero-crossing detector circuit. This circuit supplies the ac zero-crossing timing pulse to the reset sync pulse generator and the test signal generator circuits located on the Reset Sync Cards.

5.5 POWER CIRCUITS

The power circuits in the Data Acquisition Unit consist of the ac power input circuit, the regulated quad output power supply, the +12V power supply, the + 5V power supply, and the dc power input circuits.
