Table 1 RTD Type and Location Worksheet.
SEL-701 Motor Relay Application
The SEL-701 Motor Relay provides comprehensive motor protection, includ-
ing short circuit, load loss, load jam, and frequent starting protection as well as
unbalance current and phase reversal protection. The patented motor thermal pro-
tection element used by the SEL-701 Motor Relay accurately tracks the heating
effects of overloads and unbalance current.
Combining the SEL-2600 and the SEL-701 Motor Relay enhances this list of
protection features by adding remote RTD-based thermal protection.

Step 1. Connect the SEL-2600 to the SEL-701 Motor Relay using fiber-
optic cable C801FD. Connect the cable between the SEL-2600
Fiber-Optic TX output and the SEL-701 Motor Relay Fiber-Optic
RX input.
Step 2. Set the SEL-701 Motor Relay to accept the RTD temperature data
packets (see Data Packet Definition on page 11) sent by the
SEL-2600. You can use any of the following three methods to
enter the settings.
➢Relay front-panel menus: Set Relay\Relay Elements\RTD
CONFIGURATION.
➢Personal computer connected to the relay serial port, running
SEL-701PC software.
➢Personal computer connected to the relay serial port, using a
terminal emulation software package.
In the SEL-701 Relay, set the RTD Input Option setting
(RTDOPT) equal to EXT. This enables use of the external module
data. Set the RTD Location and RTD Type settings based on the
information you recorded in Table 1 on page 4. Finally, set the
RTD Alarm and Trip Temperature settings as required for your
application.
Refer to the SEL-701 Motor Relay Instruction Manual for more
details regarding calculation and entry of these settings.
Step 3. After accepting the relay settings, verify correct RTD temperature
measurement using one of these methods.
➢Relay front-panel menus: Meter Values\Thermal & RTD
Data.
➢Personal computer connected to the relay serial port, running
SEL-701PC software.
➢Personal computer connected to the relay serial port, using a
terminal emulation software package and the METER T
command.
The relay will indicate the temperatures of each connected,
healthy RTD. If the relay reports that an RTD is open or shorted,
or if the temperature reading is wrong, verify the wiring at the
SEL-2600. Also verify the RTD type connected to that input
matches the RTD type setting.

SEL-2030
Communications Processor Applications
Use the SEL-2600 RTD Module in combination with the SEL-2030 Commu-
nications Processor to enhance many protection and monitoring applications. The
SEL-2030 monitors temperature data from the SEL-2600, performs threshold com-
parisons, and sends control commands to a protective relay.
The applications shown in Figure 2, Figure 3, and Figure 4 on page 7 repre-
sent a few of the possible configurations using the SEL-2600 and the SEL-2030.
Contact SEL for help in applying these products in other configurations.
Program the SEL-2030 to perform four automated steps:
Step 1. Receive temperature data from the SEL-2600.
Step 2. Store the temperature data in memory.
Step 3. Perform temperature threshold comparisons.
Step 4. Issue control commands to a protective relay based on the
temperature comparisons.
The next few pages describe how to configure the SEL-2030 to perform the
four automated steps shown above. It is assumed that the SEL-2600 is connected to
Serial Port 4 of the SEL-2030. Refer to the SEL-2030 Communications Processor
Reference Manual and the SEL-2030 Communications Processor User’s Guide for
further information on programming concepts.
Receive Temperature Data
Connect the SEL-2600 to the SEL-2030 using an SEL-2800 Fiber-Optic
Transceiver and fiber-optic cable C801FD. Set the port settings of the SEL-2030
as shown.

Store Temperature Data in SEL-2030 Memory
Use the SET A command to reserve memory.
SET A 4
AUTOBUF = N
STARTUP =""
SEND_OPER= N
REC_SER = N
MSG_CNT = 0
ARCH_EN = N
USER = 54
The USER setting reserves a data region with 54 registers. Each register is
2 bytes for a total length of 108 bytes. This data region holds the received data
packet and mathematical equations for threshold comparisons.
The SEL-2030 automatically moves the data section of each received data
packet (see Table 3 on page 11) into the reserved USER data region at the addresses
shown in Table 2 on page 9.
The SEL-2600 data packet includes temperature information for each of the
four types of RTDs. To access the correct temperature, use the memory map loca-
tion associated with the correct RTD type.
Data from the USER region can be accessed using an absolute address or in
the form “n:USER:offset”where ‘n’is the port number and ‘offset’is the value
shown in the offset column of Table 2 on page 9. For example, access the RTD 2,
10-ohm copper data using the absolute address F80Ah or the offset form:
“4:USER:0Ah”. The examples in the remainder of this section use the offset form.
Perform Temperature Threshold Comparisons
The example SEL-2030 settings shown below compare the measured
temperature of RTD 2 (10-ohm copper) against a threshold of 28C. If the measured
temperature is valid (i.e., the RTD is not shorted or open) and is above the thresh-
old, Bit 0 of register 035H is set to ‘1’. Serial Port 4 is again assumed.
SET M 4
033h = 28 #Store temp threshold
2 034h = 4:USER:033h #Get the threshold
3 034h -= 4:USER:0Ah #Subtract the RTD temp
4 035h:0 = 4:USER:034h: 5 #Get sign bit of result
5 035h:0 *= !4:USER:0Ah: 5 #Test bit 5 of temp
6 035h:0 *= !4:USER:0Ah: 4 #Test bit 4 of temp
The text following the pound (#) symbols are comments and are not required
to set the SEL-2030.
Line 1: Stores the temperature threshold in register 033h.
Line 2: Copies the threshold to register 034h in preparation for Line 3.

Date Code 20000525 SEL-2600 RTD Module
SEL-2030 Communications rocessor Applications 9
Line 3: Subtracts the measured RTD temperature from the threshold and
stores the result in register 034h. If the result is negative, the mea-
sured RTD temperature is above the threshold and Bit 15 (the sign
bit) of 034h is set.
Line 4: Copies the sign bit (Bit 15) of 034h into Bit 0 of 035h.
Line 5: Clears Bit 0 of 35h if RTD is shorted.
Line 6: Clears Bit 0 of 35h if RTD is open.

Issue Control Commands to Relay
Connect the SEL-2030 to the protective relay. Establish communications as
outlined in the SEL-2030 Communications Processor Reference Manual and the
protective relay’s instruction manual.
Use the SET P command to set AUTO_CONFIG to “Y.”This enables auto-
matic control capabilities for the serial port connected to the relay. Use the SET A
command to set SEND_OPER to “Y.”This enables fast operate commands based
on logic bit transitions. Use the SET L command to control four breakers using fast
operate commands based on the result of a single temperature comparison.
The following example settings assume the relay is connected to SEL-2030
Serial Port 10, and the SEL-2600 is connected to Serial Port 4.
SET L 0
SBR = 4:USER:35h:0 #If above threshold open breaker
CBR = 0
SBR2 = 4:USER:35h:0 #If above threshold open breaker 2
CBR2 = 0
SBR3 = 4:USER:35h:0 #If above threshold open breaker 3
CBR3 = 0
SBR4 = 4:USER:35h:0 #If above threshold open breaker 4
CBR4 = 0
The example can be modified to control each breaker based on separate tem-
perature thresholds. The section titled Perform Temperature Threshold Compari-
sons on page 8 shows how to program the SEL-2030 for multiple temperature
comparisons. The following settings use the results of those comparisons to control
Breakers 1 and 2.
SBR = 4:USER:35h:0 #If RTD 2 > 28 degrees C open breaker
CBR = 0
SBR2 = 4:USER:38h:0 #If RTD 2 > 3 degrees C open breaker 2
CBR2 = 0
Refer to the specific protective relay’s instructional manual for more informa-
tion on fast operate commands, relay wiring, and relay configuration.
