THE ELECTRONIC SHEAR PIN! TSUBAKI SHOCK RELAY

Pioneered by Tsubaki, the Shock Relay protects your equipment against unexpected shock loads, overloads, and underloads before damage occurs. The Shock Relay protects the mechanical parts of your equipment by monitoring the current draw on your electric drive motor, and shutting it down when the motor works too hard for too long. Advantages to you: • Back to work with the press of a button • No moving parts, CPU design ensures repeatability • Precise set-points retain accuracy day after day • Permits problem notification by alarm or warning lights • Protect equipment that is up to 1000 feet away The Shock Relay adapts to virtually any kind of equipment that's driven by an electric motor and is used in applications in a broad variety of industries. Some of the common industries and applications are listed below:

Shock Relay selection is simple; it is based on the motor voltage and amperage of your equipment. Shock Relay has an unlimited life – it does not wear out. Shock Relay accepts single three-phase motors up to 600 volts.

Industry

Application

Material handling

Conveyors, turntables, elevators Pumps, scrapers, water screens

Water treatment plants

Food machinery

Screw and belt conveyors, bucket elevators

Machine tool

Tapping machines, drill presses

Chemical

Pumps, agitators, filters

Reacts only when there is a problem At installation, two set-points are made to the Shock Relay: • How hard is the equipment allowed to work as measured by motor amperage • Once the motor starts to work too hard, how soon in seconds must we stop production Balancing these two settings allows for protection when the unexpected happens, limiting damage and downtime.

TSUBAKI SHOCK RELAY THEORY OF OPERATION – HOW DOES IT WORK?

Shock time: The Shock Relay does not respond to excess current if it does not exceed the preset shock time.

Shock time: When excess current goes beyond the preset time the Shock Relay responds.

Start time: Within a set time, the Shock Relay does not respond to motor starting current.

Figure 1: Shock Relay operation example

Figure 1 above reflects a typical set-up for a Tsubaki Shock Relay. As depicted in the above example, the Shock Relay is set up to accept a higher motor amperage draw at start-up for a limited amount of time. This “Start Time” period allows the motor to spool to its steady state operation mode where maximum continuous RPM is achieved, and current draw drops to a normal value that is below the maximum “Current Value” set in the Shock Relay. As depicted, the amperage draw of the motor then momentarily increases (resulting in a drop in RPM due to induced load) above the maximum “Current Value” setting, but quickly falls back to a steady state value. Since the “Shock Time” value was not exceeded, the Shock Relay does not trip, and allows continued operation. However, as time passes by, the Shock Relay senses an increase in motor amperage draw and a drop in RPM that exceeds set current value and “Shock Time.” The overload condition sensed by the Shock Relay causes the unit to trip, resulting in the Shock Relay breaking the motor starter contact – thus, shutting the system down to prevent mechanical damage from occurring.

Important Key Concepts: * Shock Relays generally work with any voltage AC motor, single or three-phase. * Besides the power to the motor, the Shock Relay needs its own power supply. Power supply requirements generally fall into 115 or 230V single phase. * It is best practice to have one Shock Relay monitor one motor. Grouping multiple motors to a single Shock Relay generally does not give satisfactory results.

HOW TO ORDER

The model code listed below is intended to provide an example of how a given Tsubaki Shock Relay is configured. The most important aspect of ordering a Tsubaki Shock Relay is knowing the electric drive motor horsepower, voltage and amperage rating. As seen below, these three attributes are used to select the correct size range. Selecting a given series is a matter of preference based upon the features and benefits of a given Shock Relay series.

The above example for the TSBSB series Shock Relay is used to illustrate the various models within one Shock Relay series and How to Order a Shock Relay for your application. TSB: There are two families within Tsubaki’s line of electronic protection devices. The Shock Relay series begins with TSB. The Shock Monitor series begins with TSM. SB: The SB-series is one of five types of Shock Relays, each having slightly different features and focusing on different types of applications. While there is overlap between the Shock Relay series, the combinations of features such as ease of set-up, type of display, and communication options will make one Shock Relay series more desirable than another. See the preceding page for a delineation of the various Shock Relay series. 30: The numerical sizing of a Shock Relay series. The TSBSB series is available in seven sizes and for this series, the number relates to the max amperage rating for that Shock Relay. While all Shock Relays can be adjusted over a wide range of amperages, here are a few suggestions that will aid with selection: • Select the Shock Relay based on actual running amperage There is a tendency to oversize the electric motor for the application. For example, the motor nameplate may say 6 amps but measurement shows the application only uses 3 amps. Select the Shock Relay based on the 3-amp reading.

Load current can be set to stop the motor at the desired level when overload occurs. When the motor current exceeds the preset CURRENT value (at the same time, overload time continues to exceed the preset SHOCK TIME), the Shock Relay activates and stops the motor. START TIME When the motor starts there is a possibility that the motor current will exceed the set current value. To prevent the Shock Relay from tripping due to the spike in start current, start time is set a little bit longer than the period of motor start-up to ignore the spike. TEST Button Shock Relay operation can be tested stand-alone or during motor operation. (When testing the Shock Relay, continue to press and hold the TEST button longer than the set START TIME or SHOCK TIME, whichever is longer.) RESET Button After the Shock Relay activates, the RESET button is used to cancel the self-holding of the output contact. SHOCK TIME Shock time is the amount of time set until the Shock Relay will activate when overload occurs. Within the set time, the Shock Relay will not activate, even if it is overloaded.

4 to 20 mA analog signal “What is a 4 to 20 mA analog signal?” A 4 to 20 mA analog signal is a standard instrumentation signal used around the world. Instrumentation signal: • Voltage signal: DC 0 to 5 V, DC 0 to 10 V, etc. • Current signal: DC 4 to 20 mA, DC 0 to 20 mA, etc. Current signals are less susceptible to influence from electrical noise than voltage signals.

In addition, DC 4 to 20 mA, when compared to DC 0 to 20 mA, is more precise in the event of wire disruption or breaks. Therefore, DC 4 to 20 mA is used frequently, specifically in the case of long transmission distances (several tens of meters) or in answer to requests for reducing noise influence.

Example of application 1 Automatic control of the input and viscosity depending on the load by inputting the current draw to the sequencer of a crusher or mixer. 2 Figuring out the operation and loading conditions for the equipment by recording the load current of a trial unit, then using it as the basis for an optimal equipment design. 3 , 4 Activation of a digital or analog meter

Once the motor current falls below the preset level, underload is detected and a signal is sent to stop the motor. For under-load detection, the output contact is set to alarm output.* * However, in case of the underload detection, the output contact becomes choice of either alarm output or no action.

The Shock Relay does not respond to short- term current degradation if it does not exceed the preset shock time. The Shock Relay does not respond to short- term current degradation if it does not exceed the preset shock time.

The Shock Relay responds when current degradation continues for longer than the preset shock time. The Shock Relay responds when current degradation continues for longer than the preset shock time.

Notes: 1) If necessary, set the stepdown transformer (TR) depending on the voltage on the Shock Relay and electromagnetic contactor (MC). Install an isolating transformer if there is any harmonic noise generating device, such as an inverter. 2) Output relay; Normal condition: not excited, Trip condition: excited 3) Coil capacity of MC connected to the output relay of the Shock Relay is: Throw = less than 200VA Hold = less than 20VA In the event that an auxiliary relay is used, have the output relay of the Shock Relay activate the Auxiliary Relay and have the Auxiliary Relay open/close the MC.

Connection with signal converter

1) Prepare a signal converter to use the monitoring software (PCON) of TSBSC. 2) Use twisted cables and connect as follows.
