The information contained in this document supersedes all similar information that

may be found elsewhere in this manual.

Service –Due to the sophisticated

nature of the sensors and associated

instrumentation provided by PCB

Piezotronics, user servicing or repair is

not recommended and, if attempted,

may void the factory warranty. Routine

maintenance, such as the cleaning of

electrical connectors, housings, and

mounting surfaces with solutions and

techniques that will not harm the

physical material of construction, is

acceptable. Caution should be observed

to ensure that liquids are not permitted

to migrate into devices that are not

hermetically sealed. Such devices

should only be wiped with a dampened

cloth and never submerged or have

liquids poured upon them.

Repair –In the event that equipment

becomes damaged or ceases to

operate, arrangements should be made

to return the equipment to PCB

Piezotronics for repair. User servicing or

repair is not recommended and, if

attempted, may void the factory

warranty.

Calibration –Routine calibration of

sensors and associated instrumentation

is recommended as this helps build

confidence in measurement accuracy

and acquired data. Equipment

calibration cycles are typically

established by the users own quality

regimen. When in doubt about a

calibration cycle, a good “rule of thumb”

is to recalibrate on an annual basis. It is

also good practice to recalibrate after

exposure to any severe temperature

extreme, shock, load, or other

environmental influence, or prior to any

critical test.

PCB Piezotronics maintains an ISO-

9001 certified metrology laboratory and

offers calibration services, which are

accredited by A2LA to ISO/IEC 17025,

with full traceability to SI through

N.I.S.T. In addition to the normally

supplied calibration, special testing is

also available, such as: sensitivity at

elevated or cryogenic temperatures,

phase response, extended high or low

frequency response, extended range,

leak testing, hydrostatic pressure

testing, and others. For information on

standard recalibration services or

special testing, contact your local PCB

Piezotronics distributor, sales

representative, or factory customer

service representative.

Returning Equipment –Following

these procedures will ensure that your

returned materials are handled in the

most expedient manner. Before

returning any equipment to PCB

Piezotronics, contact your local

distributor, sales representative, or

factory customer service representative

to obtain a Return Warranty, Service,

Repair, and Return Policies and

Instructions Materials Authorization

(RMA) Number. This RMA number

should be clearly marked on the outside

of all package(s) and on the packing

Service, Repair, and Return

Policies and Instructions

list(s) accompanying the shipment. A

detailed account of the nature of the

problem(s) being experienced with the

equipment should also be included

inside the package(s) containing any

returned materials.

A Purchase Order, included with the

returned materials, will expedite the

turn-around of serviced equipment. It is

recommended to include authorization

on the Purchase Order for PCB to

proceed with any repairs, as long as

they do not exceed 50% of the

replacement cost of the returned

item(s). PCB will provide a price

quotation or replacement

recommendation for any item whose

repair costs would exceed 50% of

replacement cost, or any item that is not

economically feasible to repair. For

routine calibration services, the

Purchase Order should include

authorization to proceed and return at

current pricing, which can be obtained

from a factory customer service

representative.

MULTICHANNEL SIGNAL CONDITIONER MODEL 482C GENERAL OPERATION MANUAL

1-1. Introduction

Model 482C05 is a basic ICP signal conditioner that provides an adjustable current source to drive ICP sensors.

Additionally it has open, short and overload input fault condition indicators.

Model 482C15 is an ICP®signal conditioner that has all the features of the 482C05 plus jumper selectable (x1, x10, and

x100) gain options and an overload range selection. An easy to open cover, allows access to the jumper selections.

The following sections describe these devices in more detail.

1-2. Safety Considerations

WARNING SYMBOLS AND TERMS

The following symbols and terms may be found on the equipment described in this manual.

This symbol on the unit indicates that the user should refer to the operating instructions located in the manual.

This symbol on the unit indicates that high voltage may be present. Use standard safety precautions to avoid

personal contact with this voltage.

This symbol indicates that the test fixture, Model 482C15, must be connected to earth ground via the power cord.

The WARNING heading used in this manual explains dangers that might result in personal injury or death. Always

read the associated information very carefully before performing the indicated procedure.

The CAUTION heading used in this manual explains hazards that could damage the instrument.

WARNING 1: The power supply/signal conditioner should not be opened by anyone other than qualified service

personnel. This product is intended for service by qualified personnel who recognize shock hazards and are familiar

with the safety precautions required to avoid injury.

WARNING 2: This equipment is designed with user safety in mind; however, the protection provided by the equipment

may be impaired if the equipment is used in a manner not specified by PCB Piezotronics, Inc.

CAUTION 1: Cables can kill your equipment. High voltage ElectroStatic Discharge (ESD) can damage electrical

devices. Similar to a capacitor, a cable can hold a charge caused by triboelectric transfer, such as that which occurs in

the following:

Laying on and moving across a rug.

Any movement through air.

The action of rolling out a cable.

Contact to a non-grounded person

The solution for product safety: 1) Connect the cables only with the AC power off. 2) Temporarily “short” the end of

the cable before attaching it to any signal input or output.

CAUTION 2: ESD considerations should be made prior to performing any internal adjustments on the equipment.

Any piece of electronic equipment is vulnerable to ESD when opened for adjustments. Internal adjustments should

MULTICHANNEL SIGNAL CONDITIONER MODEL 482C GENERAL OPERATION MANUAL

therefore be done ONLY at an ESD-safe work area. Many products have ESD protection, but the level of protection may

be exceeded by extremely high voltage that is typically present in normal situations.

1-3. Equipment Rating

For complete specifications, please refer to the enclosed specification sheet. This equipment operates optimally at +32

to +120°F (0 to +50°C), in an environment having < 85% relative humidity. Its line power frequency range is

47 - 63 Hz.

The 482C05 and 482C15 devices require 32 - 38 VDC with approximately 200 mA to operate. In turn, they supply

26 VDC @ 2 - 20 mA excitation voltage to connected ICPsensors or in-line charge converters. The units get power

via PCB model 488B04 AC power adaptor (supplied with model), PCB model 488A11 car adapter or a 36 VDC battery

pack. All of these plug into a 5-socket DIN female connector on the rear panel. External power pin out information is

provided in section 1-8.3.

1-4. Model 482C15 System Description

Model 482C15 is a four channel signal conditioning unit designed to interface measurement signals to readout or

recording devices.

The following are features that come standard on 482C15 units:

Input fault and overload LED’s with jumper selectable overload level of +/-5V or +/-10V

Variable ICP®source current, 0 to 20 mA

Jumper selectable Voltage input mode

Jumper selectable gain of x1, x10, x100 (482C15 Only)

Lighted power indicator on the front panel

Rear panel BNC input/output connectors

Optional low pass plug in filters (477A series type) various 2-pole frequencies available (consult factory)

1-4.1. Model 482C15 ICP®Input/Output Mode

Model 482C15 contains a regulated 26 VDC power supply that provides constant current for up to 4 individual

channels. Both the output and input connections utilize BNC connectors and are brought out through the rear panel. The

unit is AC coupled only. The 482C series offers optional DC Coupling. Consult factory

1-4.2. Adjusting the Current Source

The current adjustment is located on the rear of the unit. Use a standard small flat screwdriver to adjust the “I ADJ”

potentiometer located on the rear panel between channel 2 and 3 inputs/outputs. Turning the adjustment slot clockwise

will increase the current, while counterclockwise will decrease the current. Do this adjustment only while a DC mA

meter or DMM set to mA is connected to any “ICP” BNC. One adjustment controls all channels. The unit is factory set

to 4 mA and can be adjusted between 0 - 20 mA.

Current adjust

MULTICHANNEL SIGNAL CONDITIONER MODEL 482C GENERAL OPERATION MANUAL

1-4.3. Fault Indications

The three red LED’s on the front panel are all indicators of some type of problem. The normal operation state is when

all fault lights are off. The “OPEN” light indicates that the bias voltage is over that of most sensors and is close to an

open circuit voltage of 26 VDC. The photo on the cover is shown with the unit on, and no sensors attached, so the

“OPEN” LED is on. The “SHORT” light indicates a very low bias voltage close to 0 VDC. The “OVERLOAD” light

indicates a signal level of +/- 10 V peak has been detected and the signal may be in danger of clipping. These fault

lights are active for all channels at the same time.

1-4.4. Gain selection / Jumper definition

The 482C15 has internal jumpers that are accessed by opening the top cover. On each side of the unit are small slots,

which can be accessed with a medium size flat screwdriver. Press the blade into the slot gently, and the locking device

will be released, allowing the cover to be opened. The various jumpers are all labeled on the PC board. Each channel

can be set to your selected gain and other options. The selection of all these features with jumpers allows the 482C15 to

have the functionality of many other higher priced units at an economical cost. See the table that explains the function

and number of each jumper. “X” represents channel number.
