Equipment Overview

The FANUC S2K series is a high-performance standalone brushless servo or stepper amplifier series that integrates motion controllers and user configurable I/O functionality. The controller can be configured with a rotary transformer or a serial encoder motor feedback model. The encoder based S2K servo model can only be used in conjunction with GE Fanuc S series (SLM, SDM, or SGM) servo motors. The S2K rotary transformer feedback servo controller uses GE Fanuc MTR series (3N, 3S, or 3T) servo motors or third-party motors with appropriate ratings and rotary transformer specifications.

The servo model supports continuous stall torque of 0.84-478 in lb (0.095-54 Nm), while the stepper model supports holding torque of 144-3074 oz in (16.3-21.7 Nm). The servo controller model includes four 230 VAC ratings of 4.3, 7.2, 16, and 28 ampere continuous, as well as two 460 VAC ratings of 7.2 and 20 ampere continuous (the 460 VAC model only provides feedback for the rotary transformer). The peak current of the 230 VAC servo model is twice the continuous rated value, while the 460 VAC servo model is 1.5 times the continuous rated value. The rated value of the stepper controller is 5 amperes.

Support DeviceNet ™  The PROFIBUS communication model includes 14 discrete I/O points. 4.3 and 7.2 ampere servo models and stepper models can also provide 21 I/O points instead of DeviceNet or PROFIBUS communication. All drivers are capable of supporting Modbus/RTU protocol. If the optional Modbus adapter (product number IC800MBUSADP) is used, the standard RS-232 serial port can be used for multi-point applications. This adapter is an externally installed multi-point RS-232 to RS-485 serial port converter.

The S2K series controller is optimized for use with GE Fanuc S series or MTR series servo and stepper motors. If the motor and amplifier are not properly matched, overload and possible component damage may occur. Tables 1-1 to 1-3 show the recommended pairing of components.

The S2K series stepper controller requires a single-phase 115 VAC power supply. The S2K series servo controller models rated at 230 VAC and 4.3 or 7.2 amperes can operate on 115 VAC single-phase or 230 VAC three-phase, while all other models are rated for three-phase input. The 230 and 460 VAC models are designed to operate from three-phase power sources, but can be used with single-phase power sources.

The S series servo motors optimized for the S2K series controller range from 30 W to 5 kW and are rated at 230 VAC to achieve full speed. Using a 115 VAC power supply will result in a reduced operating speed of approximately half of the rated speed.

The 30 to 1000 watt S series servo motors (SLM models only), MTR-3S and MTR-3N series, and all stepper motor models are designed with standard NEMA shaft and flange mounting configurations for easy installation onto existing gear reducers and couplings. The 750 watt S series motor is installed with a super large shaft diameter (0.625 inches) for NEMA 34 to handle the peak torque rating of this model. The S series motor models ranging from 1 to 5 kW (except for the SLM100 1kW motor) and all MTR-3T series motors have metric installation configurations.

All servo motors can be equipped with an optional 24 VDC holding brake. These brakes are spring set, electrically released models designed to maintain static loads. The user must provide a separate 24 VDC brake power supply. The 30-750 watt S series motor has a pigtail cable with a box type connector for connecting the motor power supply, encoder, and brake. The 1000 to 5000 watt S series motors have MS style connectors, and the brake power supply (if needed) is integrated with the motor power supply in a common connector/cable. The MTR series servo motors include MS type connectors for brake power input. The MTR-3N and MTR-3T series brake motors integrate the brake power supply and motor power supply into the same cable. The MTR-3S brake motor requires a separate brake power cable (CBL-30-BT).

The S2K series controller is configured and programmed using Motion Developer software on a personal computer. This software is an independent application that works in the Machine Edition software environment, providing tools for beginners to simplify programming and direct code input for advanced users.

Contains curves for MTR series stepper motors/controllers, S-series servo motors/controllers, and MTR series servo motors/controllers, demonstrating the relationship between motor speed and output torque. The motor can operate continuously at any speed and torque combination within a specified continuous operating range.

Servo motor derating based on ambient temperature

The S series motor generates continuous torque as shown in the speed/torque curve (Section 2.2.2) within a certain ambient temperature limit, depending on the motor model. The following curve describes the continuous torque derating required for operation at ambient temperatures above this rated value and up to a limit of 40oC. The intermittent torque available for each motor does not require derating.

The MTR series servo motors are rated at an ambient temperature of 25oC and are mounted on 10 “x 10” x 0.25 “aluminum heat sinks. For motors operating at higher ambient temperatures, the continuous torque of the motor must be reduced as follows: continuous torque at ambient temperature, toC=rated continuous torque x (155-t)/130.

Adequate precautions shall be taken when installing the motor to ensure proper protection from excessive liquid and spray exposure.

Servo motor maintains brake

The servo motor can be equipped with an optional integrated parking brake. The brake is designed for fail safe operation and must be powered by a 24 Vdc power supply to release the brake.

NEMA motor installation

The MTR series and S series motors have installation configurations as shown in the table below. For dimensional information about these motors (including installation dimensions), please refer to the mechanical drawings in Chapter 3.

The MTR series stepper motors have standard NEMA shaft and flange installation configurations, as shown in Table 2-17 below. For the size information of these motors, please refer to the mechanical drawings in Chapter 3.

S series servo motor vibration test

These motors have two types of vibration tests, namely scanning test and resonance point test.

Scanning test: The motor undergoes a 5G variable frequency test on each of the three axes (X, Y, Z) for eight hours. For the purpose of these tests, the X-axis is parallel to the motor axis, the Y-axis is parallel to the encoder connector, and the Z-axis is at a 90 degree angle to X and Y. In this test, the vibration frequency increased from 20 to 3000 Hz within two minutes, and then decreased from 3000 to 20 Hz within two minutes. This pattern was repeated for eight hours.

Resonance point test: Firstly, identify the resonance frequency with the highest vibration when testing the motor in three directions (X, Y, Z) at a variable frequency of 5 G (20 to 3000 Hz). Then, the motor vibrates 10 million times in each direction (X, Y, Z) at the identified resonance frequency.

Equipment Overview

Hydran ™  201Ti is a small and easy to set up continuous dissolved gas analysis (DGA) monitor for oil, which can provide IEEE ®  The basic information used in standard C57.104 can serve as an important first line of defense for transformers, providing early warning of fault situations and reducing the risk of unplanned power outages. It adopts fuel cell technology (referred to as fixed instrument method 3 in the standard) and has two gas sensors to choose from: the world-renowned “Hydran composite gas” sensor (100% responsive to hydrogen and sensitive to carbon monoxide, acetylene, and ethylene) and the more basic “hydrogen only” sensor (focused solely on hydrogen production). This monitoring unit is installed on a single valve and uses dynamic oil sampling, without the need for pumps or additional pipelines to connect to different valves. Due to its simple function and easy to understand information, it has been one of the preferred monitoring devices for many years and ranks among the top in terms of installation volume among all DGA monitoring devices.

Main advantages

Continuously measure critical fault gases to understand the condition of the transformer.

Gas sensors can be selected: traditional “composite gas” sensors or more basic “hydrogen only” sensors.

Remote transmission of gas ppm and gas change rate values to avoid on-site visits and achieve remote monitoring.

The fourth generation design, which has undergone continuous improvement, has sold over 25000 units worldwide.

Application scenarios

Power company: Provide simple and effective solutions for less important transformers, focusing on and prioritizing asset replacement strategies.

Industrial factories: Reduce the risk of process interruptions caused by power failures and minimize costly production downtime.

Convenient asset supervision: permanently installed on a single transformer oil valve, without the need for additional pipelines or pumps; The “composite gas” sensor responds 100% to hydrogen gas (a common fault gas) and is sensitive to carbon monoxide (paper overheating), acetylene (arc), and ethylene (oil overheating), thus covering the main root cause of the fault; The ‘hydrogen only’ gas sensor is simpler and only responds 100% to general faulty gas hydrogen.

Configurable alarms

An alarm is triggered when abnormal levels of faulty gas are detected.

Two alert levels can be set (one for warning and one for alert) to display an increase in severity.

The alarm can be set at the gas ppm level or the hourly or daily gas change rate (ROC).

Automatic self check every 15 days, if a fault is detected (including power failure, oil valve closure, sensor or battery replacement), a service alarm will be triggered.

HMI

Backlit LCD display screen shows gas information.

A keyboard used to stop devices and confirm alarms.

GE’s highly acclaimed Perception ™ Software compatibility, downloadable, trend analysis, and analysis of transformer data.

Mark IV improvements

A thorough overhaul was conducted to improve the durability of the sensor, and new electronic boards and power supplies were used to comply with RoHS standards, while also enhancing the reliability and performance of the equipment.

Equipped with a local USB port, replacing the RS-232 port that is no longer available on most on-site laptops.

Adopting Modbus through isolated RS-485 ®  Protocol communication realizes the digital output of registers.

Controller

Hydran 201Ti can be connected to optional controllers to facilitate communication with multiple units and create local networks.

Ci-1 controller: a single channel controller that can replicate some human-machine interface functions (gas value display, alarm button). It is ideal when the 201Ti is installed in a difficult to reach position on the upper valve of the transformer. It can also lead out alarm relay contacts and analog outputs for easy wiring.

Ci-C controller: capable of receiving up to four 201Ti gas ppm data, providing a single communication point for all four monitoring instruments, without alarm relays or analog outputs, ideal for protecting 3 single-phase transformers and 1 backup transformer.

Through its RS-485 port, up to 32 controllers or 201Ti can be daisy chained, with a maximum chain length (total of all cables) of 1200 meters (4000 feet). All 201Ti connected to any daisy chained controller can be accessed through any controller in the local network, making communication easier, such as by installing only one RS-232 modem.

Technical specifications

Measurement: The fuel cell type sensor is located behind the breathable membrane in contact with the transformer insulation oil, with a measurement range of 25-2000 ppm (volume/volume, hydrogen equivalent), an accuracy of ± 10% reading ± 25 ppm (hydrogen equivalent), and a response time of 10 minutes (90% step change). The “composite gas” sensor has a 100% response to hydrogen gas and varying degrees of sensitivity to carbon monoxide, acetylene, and ethylene, with a repeatability of ± 5% of readings or the larger of ± 5 ppm; The “hydrogen only” sensor only responds 100% to hydrogen, with interference from carbon monoxide, acetylene, and ethylene at concentrations less than 3%, and a repeatability of ± 5% of readings or the larger of ± 10 ppm.

Equipment Overview

Hydran ™  M2 is a continuous online dissolved gas and oil moisture monitoring device for transformers, which can alert staff of faults in transformers, provide critical monitoring information, and reduce the risk of unplanned power outages. By connecting additional sensors, more information can be obtained and correlated with DGA and moisture values for in-depth analysis of transformer status. Its data can be transmitted as raw data through various communication methods, and can also be transmitted using IEEE based methods ®  The on-board calculation of standard transformer mathematical models is converted into useful information.

Main advantages

Continuously measure the dissolved fault gases and moisture in the oil for early identification before potential problems develop into serious transformer faults.

Gas sensors can be selected: traditional “composite gas” sensors or more basic “hydrogen only” sensors.

Built in transformer model calculation based on IEEE standards (only applicable to mineral oil).

Multiple communication options and protocols for easy integration into SCADA or DCS systems.

The validated third-generation design has a large installation base worldwide.

Support new low flammability ester oils and mineral transformer insulation oils.

Application scenarios

Power company: Provide integrated solutions for important medium-sized transformers, focusing on and prioritizing asset replacement strategies.

Industrial factories: Reduce the risk of process interruptions caused by power failures and minimize costly production downtime.

Asset supervision: Easy to permanently install on a single transformer oil valve, without the need for additional pipelines or pumps, and can choose to input other sensors; Only hydrogen “or” composite gas “sensors are optional, where the” composite gas “sensor responds 100% to hydrogen (general fault gas) and is sensitive to carbon monoxide (paper), acetylene (arc), and ethylene (oil); The moisture sensor measures water in the oil, which is the result of insulation paper degradation (producing carbon monoxide and water) or gasket leakage.

Configurable alarms

When abnormal levels of faulty gas or moisture are detected, an alarm can be triggered with two alarm levels (one for warning and one for alarm) to indicate an increase in severity.

The alarm can also be set on the value of the optional analog input card or on the optional calculated transformer model.

Automatic self check every 15 days, and if a fault is detected (including power failure, oil valve closure, sensor failure), a service alarm will be triggered.

Mark III improvements

A thorough overhaul was conducted to improve the durability of the sensor, and new electronic boards and power supplies were used to comply with RoHS standards, while also enhancing the reliability and performance of the equipment.

Suitable for transformers using mineral insulating oil, now also suitable for ester oil (natural or synthetic).
