BASLER TIME OVERCURRENT RELAY BE1-51A SOLID STATE 1 PH

SPIKE SUPPRESSION MODULE

Some higher impedance power sources (such as power isolation transformers

and PMGs) may have enough inductance to cause potentially damaging voltage

spikes in the power output stage of the SSR Voltage Regulator. In these cases,

Basler Electric recommends the use of the Spike Suppression Module which was

supplied with the Regulator to filter out these potentially damaging voltage spikes.

Refer to Section 2 for mounting and interconnection instructions.

Voltage Regulator Mounting

The Voltage Regulator will operate when mounted in any position, however, it 

should be vertically mounted to obtain optimum cooling. The Regulator can be

mounted in any location where the ambient temperature does not exceed the

operational limits. Due to its rugged construction, the Regulator can be mounted

directly on the generator. Mounting hardware should be selected based upon the

vibration and shock expected to be encountered during shipping/transport and

normal operation. Refer to Figure 2-1 for the outline drawing of the unit which

provides overall and mounting dimensions.

Mounting Hardware

The AVC Sensing Module can be mounted directly on a genset using #10-32 or

equivalent hardware. A lock washer should be used between the screw head and

body of the module. Torque applied when tightening the mounting hardware

should not exceed 25 inch-pounds (2.8 N•m).

The AVC Sensing Module provides a convenient and cost-effective method

for expanding the applications where AVC63-12 and AVC125-10 voltage

regulators can be applied. The AVC Sensing Module increases the nominal

sensing voltage of style BX AVC63-12 and AVC125-10 voltage regulators

from 200/240 Vac to 480 Vac or 600 Vac. The AVC Sensing Module is

compatible with nominal sensing frequencies of 50/60 Hz and 400 Hz.

A compact, rugged (potted) case enables the AVC Sensing Module to be

mounted directly on the generator.

Other than making connections during installation, the AVC Sensing Module

requires no adjustment or calibration.

The AVC Sensing Module is housed in a potted, plastic case that can be

mounted in any convenient position.

BE1-BPR Breaker Protection Relays are three-phase and neutral, 

microprocessor based relays designed to provide power systems 

with protection and security against monitored breaker failure or

to initiate multiple shot breaker reclosings.

These relays incorporate a powerful means of programming internal

relay logic to satisfy a wide range of user requirements without making

any relay hardware changes. Microprocessor-based design provides

the basic features of a programmable logic controller (PLC) combined

with an instantaneous overcurrent module.

Cased in a 19 inch rack-mount or a vertical panel mount, the relay offers

installation versatility. A wide temperature, 2 lines by 16 character display

provides diagnostic and setup information. Two RS-232 serial ports (one

each front and rear) and one RS-485 serial port (rear) provide remote

communication and relay control.

Built-in diagnostics and monitoring features provide information for both

the health of the relay and the health of the breaker being monitored.

Relay diagnostics include continuous background monitoring of the

power supplies, analog-to-digital (A/D) converter, random-access memory

(RAM), read-only memory (ROM), and electrically-erasable programmable

ROM (EEPROM). A dedicated alarm (ALM) relay output provides power 

supply, microprocessor, and software alarm status. Breaker diagnostics

include a timing diagnostic log, breaker contact duty monitoring, breaker

resistor protection, and breaker arc detection.

Other monitoring features include oscillographic fault records and fault

summary logs. BE1-BPR relays use the Inter-Range Instrumentation Group

(IRIG), Format B for high timing accuracy and resolution.
