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.

MULTICHANNEL SIGNAL CONDITIONER MODEL 482C GENERAL OPERATION MANUAL

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

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 482C15/482C05 devices require 34-38 VDC with 200 mA to operate. In turn, they supply 26 VDC @ 2 to 20 mA

excitation voltage to connected ICPsensors or in-line charge converters. The units get power via AC power adaptor

PCB Model 488A04, 36VDC battery pack, or a car adapter which all plug into a receptacle on the rear panel (PCB

Model 488A11).

1-4. Model 482C15 System Description

The 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 L.P. plug in filters (477A series type) various 2-pole frequencies avail. Consult factory

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

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

1-4.3. Fault Indications

The three red LED’s on the front panel are all indicators of some type of problem. The normal good 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 26VDC. 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 0VDC. The “OVERLOAD” light

MULTICHANNEL SIGNAL CONDITIONER MODEL 482C GENERAL OPERATION MANUAL

indicates a signal level of +/-10V 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. The top cover is secured by four (4)

Philips head screws on the bottom of the unit. Place the unit on a clean, flat surface (Electrical Static Discharge

protection recommended) and remove the four screws. Carefully rotate the unit and place it on its feet, then gently

remove the cover.

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. Once jumpers have been placed as needed, replace cover –taking special care to align the front and back

panels with the slots in the top cover. Insert the four (4) screws and tighten to 5 in-lbs.
