Page 93: Equation 3.4
To preserve insulation life, NEMA standards suggest a 1°C reduction in RTD trip temperature for each 1°C rise in ambient temperature over 40°C. When you enable RTD biasing, the SEL-701-1 Monitor automatically reduces the RTD trip temperatures for all winding RTDs when ambient temperature is above 40°C.

Page 175: Section 6: Commissioning
Section 6 Commissioning Introduction This section provides guidelines for commissioning and testing the SEL-701-1 Monitor. SEL performs a complete functional check and calibration of each monitor before it is shipped. This helps to ensure that you receive a monitor that operates correctly and accurately.
Page 176: Monitor Commissioning Procedure
Monitor Commissioning Procedure Monitor Commissioning Procedure Introduction This procedure is a guideline to help you enter settings into the SEL-701-1 Monitor and verify that it is properly connected. Modify the procedure as necessary to conform with your standard practices. Use the commissioning procedure at initial monitor installation; you should not need to repeat it unless major changes are made to the monitor electrical connections.
Page 177 Step 9. Verify monitor ac connections. Connect the protective monitor ac test signal source to the SEL-701-1 Monitor through the motor control center wiring. (You may connect directly to the monitor; however, this does not verify the accuracy of the wiring in the motor control center.) Apply rated ac current (1 A or 5 A) to the monitor phase...

This appendix describes Modbus RTU communications features supported by the SEL-701-1 Monitor at the rear-panel EIA-485 port. Complete specifications for the Modbus protocol are available from Modicon on their web site: www.modicon.com. The SEL-701-1 Monitor supports Modbus RTU protocol when you enable Modbus protocol using the rear-panel serial port settings.

Cyclical Redundancy Check 2 bytes The SEL-701-1 Monitor SLAVEID setting defines the device address when the monitor rear-panel port is set for Modbus communication. Set this value to a unique number for each device on the Modbus network. For Modbus communication to operate properly, no two slave devices may have the same address.

Page 371: Appendix E: Motor Thermal Element
Appendix E Motor Thermal Element Introduction The SEL-701-1 Monitor provides effective motor thermal protection using a patented protection algorithm. The monitor offers three convenient methods to set the thermal element. They are: Motor ratings method. Generic thermal limit curve method.

Page 373: Purpose Of Motor Thermal Protection
The purpose of motor thermal protection is to allow the motor to start and run within the manufacturer’s published guidelines, but trip if the motor heat energy exceeds those ratings due to overloads, negative-sequence current, or locked rotor starting. SEL-701-1 Monitor Date Code 20011009...
Page 374 The SEL-701-1 Monitor thermal element, with its integrated design, offers distinct advantages over the use of discrete elements. The SEL-701-1 Monitor thermal element always operates in one of two modes: starting or running. In starting mode, the thermal element provides locked rotor...

When rotor speed is zero, the counter-rotating poles induce fundamental frequency currents in the rotor: negative-sequence slip equals positive-sequence slip, S. When the rotor is spinning at near synchronous speed, the counter-rotating magnetic poles induce SEL-701-1 Monitor Date Code 20011009...
Page 377: Equation E.4
The differences in the positive- and negative-sequence heating factors immediately suggest that the thermal element should have two states representing the starting and running states of the motor. The SEL-701-1 Monitor thermal element automatically selects which state to use based on the measured positive-sequence current.
Page 378: Motor Starting Protection
2.5 times full load current, the monitor switches from the starting thermal element to the running thermal element. The present heat estimate, U, is transferred directly to the running element, representing the heat build-up that occurred during motor starting. SEL-701-1 Monitor Date Code 20011009...

Page 383: Motor Starting Thermal Capacity
The SEL-701-1 Monitor provides two facilities to help ensure that a motor start is not attempted while the motor is still too hot to be started safely. The Thermal Capacity Used to Start (TCSTART) setting allows you to define a fixed value of thermal capacity that you expect the motor to use on a start.

Page 431: Glossary
Alias User assigned name of a Relay Word bit used in the SEL-701-1 Monitor Sequential Events Recorder (SER) function. The assigned alias appears in the SER report in place of the Relay Word bit, making the SER report easier to review.
Page 432 ASCII Abbreviation for American Standard Code for Information Interchange. Defines a standard way to communicate text characters between two electronic devices. The SEL-701-1 Monitor uses ASCII text characters to communicate using its front- and rear- panel EIA-232 serial ports. Assert To activate;...
Page 433 The unbalance element can trip the motor in the presence of heavy unbalance to prevent rotor damage due to overheating. In the SEL-701-1 Monitor, this element works together with the motor thermal element which also provides unbalance current protection.
Page 434 When a motor ground fault occurs, this current can be large. Neutral current measured by the monitor IN input. The IN input is typically connected to the secondary winding of a window-CT for motor ground fault detection on resistance-grounded systems. SEL-701-1 Monitor Date Code 20011009...
Page 435 Glossary GL.5 Instantaneous Meter-Load Profile Instantaneous Meter Type of meter data presented by the SEL-701-1 Monitor that includes the present values measured at the monitor ac inputs. The word “Instantaneous” is used to differentiate these values from the measurements presented by the demand, thermal, energy, and other meter types.
Page 436: Appendix E: Motor Thermal Element
GL.6 Max/Min Meter -Phase Rotation Max/Min Meter Type of meter data presented by the SEL-701-1 Monitor that includes a record of the maximum and minimum of each value, along with the date and time that each maximum and minimum occurred.
Page 437 Fast Operate command, or Modbus command. Residual Current The sum of the measured phase currents. In normal, balanced operation, this current is very small or zero. When a motor ground fault occurs, this current can be large. SEL-701-1 Monitor Date Code 20011009...
Page 438: Equation E.8
Abbreviation for Resistance Temperature Device. An RTD is made of a metal having a precisely known resistance and temperature coefficient of resistance. The SEL-701-1 Monitor and SEL-2600 RTD Module can measure the resistance of the RTD, and thus, determine the temperature at the RTD location.
Page 439 The second and third voltage transformers are connected to measure the voltage from B-phase and C-phase-to-ground, respectively. This connection is frequently called ‘four-wire wye,’ alluding to the three phase leads plus the neutral lead. SEL-701-1 Monitor Date Code 20011009...
