Repair and Maintenance

PCB guarantees Total Customer Satisfaction through its

“Lifetime Warranty Plus” on all Platinum Stock Products

sold by PCB and through its limited warranties on all other

PCB Stock, Standard and Special products. Due to the

sophisticated nature of our sensors and associated

instrumentation, field servicing and repair is not

recommended and, if attempted, will void the factory

warranty.

Beyond routine calibration and battery replacements

where applicable, our products require no user

maintenance. Clean electrical connectors, housings, and

mounting surfaces with solutions and techniques that will

not harm the material of construction. Observe caution

when using liquids near devices that are not hermetically

sealed. Such devices should only be wiped with a

dampened cloth—never saturated or submerged.

In the event that equipment becomes damaged or ceases

to operate, our Application Engineers are here to support

your troubleshooting efforts 24 hours a day, 7 days a

week. Call or email with model and serial number as well

as a brief description of the problem.

Calibration

Routine calibration of sensors and associated

instrumentation is necessary to maintain measurement

accuracy. We recommend calibrating on an annual basis,

after exposure to any extreme environmental influence,

or prior to any critical test.

PCB Piezotronics is an ISO-9001 certified company whose

calibration services are accredited by A2LA to ISO/IEC

17025, with full traceability to SI through N.I.S.T. In

addition to our standard calibration services, we also offer

specialized tests, including: sensitivity at elevated or

cryogenic temperatures, phase response, extended high

or low frequency response, extended range, leak testing,

hydrostatic pressure testing, and others. For more

information, contact your local PCB Piezotronics

distributor, sales representative, or factory customer

service representative.

Returning Equipment

If factory repair is required, our representatives will

provide you with a Return Material Authorization (RMA)

number, which we use to reference any information you

have already provided and expedite the repair process.

This number should be clearly marked on the outside of

all returned package(s) and on any packing list(s)

accompanying the shipment.

SENSORS AND INSTRUMENTATION FOR MACHINE CONDITION MONITORING

Introduction

The 685B-Series is an electronic vibration switch designed to monitor vibration levels and trip an alert when a

specified limit is exceeded. A second onboard relay trips an alarm that can be used to shut down a piece of

equipment or act as a secondary alert level. An onboard accelerometer with precision electronics insures

reliability and accuracy.

General Features

Embedded or external piezoelectric accelerometer for improved accuracy and frequency response.

Vibration range can be measured in acceleration, velocity or displacement (factory set).

Provides dual 5 Amp Triac (SPST) or 10 Amp Form C (SPDT) relay outputs.

Adjustable trip limits and time delay via single turn potentiometers.

Accommodates normally open (NO) and normally closed (NC) wiring schemes.

Continuous or latching switch action.

Local reset button and remote reset capability.

LED indicators for power, alert and alarm.

Screw terminal blocks for easy wiring.

Mounts directly to the equipment being monitored via four bolt pattern.

Flexible design allows for various custom requirements.

4-20 mA field calibration feature for improved accuracy.

Raw vibration & 4-20 mA outputs as standard.

Installation and Wiring

Installation

The 685B-Series is designed to be mounted directly on the equipment to be monitored using a four-bolt pattern.

There are also options to retrofit existing 3 bolt pattern installations. (Model 080A209 mounting plate required-

see optional accessories on page 13). Use grease between all surfaces to insure specified frequency response,

otherwise performance will be degraded. The axis of vibration measured by models with internal accelerometers

is perpendicular to the mounting orientation of the unit.
