Product Description
The RSHR Midi is a compact
easy-to-use AC semiconduc-
tor motor controller. With this
controller 3-phase motors
with nominal currents up to
18A can be soft started
and/or soft stopped. The
RSHR Midi controls 2 phases
only, one phase is continously
connected to the load. Soft
starting and soft stopping is
achieved by controlling the
motor voltage. During running
operation the semiconductors
are bypassed by internal elec-
tromechanical relays. Starting
and stopping time as well as
initial torque can be indepen-
dently adjusted by built-in
potentiometers.
LEDs indicate the status of
the controller including an
alarm status in case of over-
temperature in the RSHR...V21
models. The RSHR Midi
comes with an integrated
heatsink and is ready to
mount on DIN rail.

RSHR MIDI
The motor controller provides
by-passing of the semicon-
ductors during running opera-
tion. Therefore the semicon-
ductors can only be damaged
by short-circuit currents dur-
ing ramp-up and ramp-down.
Please note that the motor
controller does not isolate the
motor from the mains.
Figure 1: Protection of the
device when using fuses.
Protection with semiconduc-
tor fuses is intended to pro-
tect the motor feeder and
motor controller from damage
due to short-circuit.
Figure 2: Protection using a
thermal-magnetic motor
protection relay.
The motor feeder is protected
but damage to the motor
controller is possible. When
motor failure occurs, if part of
the motor winding limits the
fault current and the motor
feeder is protected, this type
of protection can be consid-
ered acceptable.
Figure 3: Secondary con-
ductors.
3.1: Control using a 2-position
switch.
When K is closed, the control
input is supplied to A1, A2 or
A3 and soft starting of the
motor is performed. When K
is opened, soft stopping is
performed.
3.2: Auxiliary Relay
(For RSHR...BV21 models)
The End of Ramp relay 11, 12
(NO) can be used in series
with the supply to the coil of
an external bypass contactor.
Figure 4: Control using ON
and OFF push buttons
Pushing S1 soft starts the
RSHR. Pushing S2 soft stops
the RSHR. K is an auxiliary con-
tact of the mains contactor.
Figure 5: Control using 2
phases
Connecting input A1, A3 to
two of the incomming lines
will soft start the motor when
K is operated. When K is
switched off, the motor will
stop (no soft stop). This con-
figuration does not apply to
the RSHR60.... versions.
Figure 6: Control when
using operational voltage
greater than 480V
Connecting A1 to Neutral and
A3 to one of the incoming
phases (or vice-versa) will soft
start the motor when K is
closed. When K is opened, the
motor will stop (no soft stop).
