OverviewSafety Warnings

Read and follow all Warnings, Precautions, Notes, and Instructions included in thisdocument.

A Warning identifies an immediate hazard that exists that poses some probabilityof causing death or serious injury.

A Caution identifies potential conditions and actions that have the possibility of

death or severe injury. A Note identifies the need for general safety practices which, if violated, could

cause injury to personnel or damage to equipment.

High voltages are exposed during operation. Do not touch exposedsurfaces during test.

Caution Verify wiring connections prior to applying power to the system. Damageto the equipment could result from incorrect connections.

Note Inspect system ground and bonds prior to power application. Shockhazard could exist if proper ground is not maintained.

Motor Control Unit

The High Voltage Probe unit is connected directly to the high voltageoutput of the main contactor, which can be up to 5000 Volts. These HighVoltages may be present during operation and set-up, and should beconsidered hazardous.

Introduction

The Backspin Relay and HV Probe is an optional part of the Motor Controller system. The

backspin equipment is generally used in electric submersible pump applications in the oilfield or

water well applications where detection of the backward spin of the pump is desired. When the

motor is shutdown or turned off, the existing fluid in the production tubing causes the

pump/motor to turn backwards as the fluid is falling back into the well. If the motor is started

while this backspin is happening, this could cause damage to the equipment. The BackspinRelay can detect this backspin and prevent the manual or automatic starting of the pump until

the back spinning has stopped.

Installation and Wiring

The HV Probe unit is connected directly to the high voltage output of the

main con tactor , which can be up to 5000 Volts. These High Voltages may

be present during operation and set-up, and should be considered

hazardous.

High Voltage Probe

The High voltage probe has two sets of connections. The high voltage connection consists

of three high voltage wires that are connected directly to the output of the 3-phase voltage of

the contactor or motor leads. This HV connection is rated up to 5000 volts AC. A small cable

fitted with a connector is used to connect the probe to the backspin relay unit. Mounting

holes on the probe allow the probe to be mounted to the inside of the switchboard panel.

Backspin Relay

The backspin relay is connected to the Motor Controller system via the provided patch cord

with the RJ-45 type connectors. All parts of the controller units are tied together in a daisy

chain fashion using these patch cords. Each module on the controller units are equipped

with two receptacles for the RJ-45 connectors to allow this to be done easily. This provides

communication to the controller in order for the controller to prevent starting when backspin

is in motion.

A connector on the backspin relay marked “Backspin Probe Connection Only” is where the

matching connector is plugged in from the HV probe.

A third connector on the backspin relay is used for external connection and/or stand-alone

operation of the backspin detection. For stand alone operation, the 120VAC power, neutral,

and ground pins must be connected to an external power source. External devices for

detection of the backspin can use the relay common, relay NC, and relay NO pins. When

the motor is turning, the contacts will switch. This is not a standard configuration.

There is one each of RX and TX LEDs for indicating transmit and receive status on the

communication link. One blue LED lights to indicate motor spin, which will blink at the

frequency of the motor spin whether it is running or in backspin.

Backspin Detection SetupThe backspin detection is setup using the motor controller display parameters. Under the

Fault Activations Menu, the Backspin Enable parameter is set to yes if backspin detection is

desired.

Once the backspin has been detected, after a motor stop command or shutdown fault, the

Motor Controller Display will show direction CBA/ABC and RPM in HZ this is held in the

controller memory until updated approx every 2 sec, or until the backspin relay detects that

the motor has stopped turning and lockout is cleared. This means if communication betweenmotor controller and backspin relay is lost it will not reset the backspin speed or direction

and you will be unable to clear lockout without changing the backspin Fault Activation Menu

Enable to NO.

Stand Alone Backspin SetupThe backspin relay system can be used to prevent starting pumps while spinning, using the

120VAC input, the backspin relay output, and a motor controllers Digital or aux input and an

N/C contact on the contactor. The Backspin relay output changes state only while backspin

is present the N/O becomes closed and the N/C becomes open. Using the N/O and

common contacts and going thru the N/C contacts on the contactor into the digital/aux input

to the motor controller, this will allow the unit to start and run if the digital input/aux is set to

N/C to shut down. Once the contactor is pulled the backspin alarm becomes active but the

signal will not go thru the N/C contacts of the contactor until a shut down occurs, then the

backspin alarm will remain closed until the spin stops.
