TOSHIBA
MOTOR PROTECTION RELAY

MODEL S2E21

MOTOR PROTECTION RELAY
TOSHIBA MODEL S2E21
TOSHIBA'S motor protection relay, Model S2E21, is a total motor protection and monitoring package
for all motor applications . It has all the protective features necessary, including a display of running
event data.

FEATURES
1.

TEMPERATURE SIMILATION FOR OVERLOAD

MAINTENANCE DATA

Every motor application is protected by
temperature similation used for overload
protection .

Rotor and stator temperatures, number of
starts, running time, history of key parameters
before trip, running event data .

SIMPLE OPERATION

MONITORING SYSTEM

Relay programming is made simple by clear,
easy to follow instructions, large LCD display
with integral programmer, or by computer.

Built-in memory card supports on-going maintenance procedures.

ALL TYPES OF PROTECTION

Standard RS485 communication port is stan
dard for all relays .

Thermal overload, instantaneous overcurrent,
overcurrent, current unbalance, undercurrent,
locked rotor, repeated starting and ground fault.

OPERATION
Simple, straightforward operation .
Standard relay is drawout construction . CT connections are shorted automatically when relay is
drawn out.
Memory card is included as a standard accessory.

Running Monitor (red)
Stop - Light is off
Run - Light is on (steady)
Starting - Light blinks in 1 second intervals
Overload Detection
Light blinks 3 times/second
Error Indicator (red)
Lighted when relay detects self-checking error
Trip Indicator (yellow)
Lighted when any protective function causes
relay to trip. LCD display will show what type of
trip occurred .

LCD DISPLAY OPERATION
Each information cell is assigned a separate page display. Selecting the page to view the desired
display is performed by pressing `Page' and then either the page number or the Up or Down
cursor key.
Auto-shutoff feature. LCD display is turned off automatically if no new LCD screen is selected within
4 minutes .
Set points are protected by PASSWORD ID security feature. Settings may be viewed, but not
changed, except by personnel authorized with the correct password.

PROTECTION
Overload protection, locked rotor protection, and repeat start protection are accomplished by a scientific calculation performed by the relay, simulating real-world temperatures .
The temperature simulation protection method calculates the rotor and stator heat rise based on
measured line currents, the motor thermal heating time constant, and the motor cooling time constant. These values are constantly monitored by the relay and compared to the set trip points . This
method offers complete protection for all motor applications .
If RTD's are present in the motor the auto-learning function will allow the relay to read the actual
heating and cooling time constant of any type of motor, eliminating the need for programming the
heating and cooling time constants by an operator . Starting currents and acceleration time may also
be calculated by the relay in auto-learning mode .
