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
contact of the mains contactor.
Figure 5: Control using 2
phases
Connecting input A1, A2 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).
Wiring Diagram
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 con-
troller 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 pro-
tection can be considered
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
and soft starting of the motor
is performed. When K is
opened, soft stopping is per-
formed.
3.2: Motor PTC input
When the motor PTC sensor
is connected to P1, P2 the
motor controller detects over-
heating of the motor windings.
3.3: Auxiliary Relays (Available
on RSHR...

types only!)
The Alarm relay 11, 22 (NC)
can be connected in series
with the supply to the coil of a
mains contactor. The Bypass
ON relay 21, 22 (NO) can be
used in series with the supply

Operation Diagrams for RSHR
Notes
Note1: After activation of the by-pass relay, there is a delay of 1 sec, during
which removal of the control input will not initiate the ramp-down function.
Note 2: Cycling of the control input should be limited to a rate not exceeding 3
seconds ON and 3 seconds OFF. At faster cycling times, it is not guaranteed that
the output of the unit will respond to the given input.
Important: The number of starts per hour and Overload Cycle values should
always be taken into consideration when cycling is used.
Note 3: Auxiliary relays available only on RSHR...V21 types
Note 4
:
A phase loss on L1 or L2 causes the device to reset as these phases
provide the internal power supply.
Note 5: Phase sequence and phase loss alarms are only detected if they occur
during power up, when L1, L2, L3 are switched ON.
Note 6: When a motor PTC is connected, electromagnetic noise may be con-
ducted into the unit. Thus if abnormal function is observed, the use of ferrite
beads on the PTC wire (at the unit end) is recommended.
Note 7: Repetitive voltage dips on phase L1 and/or L2 during operation may
lead to overheating of the motor. In case the by-pass relays are activated and
the repetition rate of these dips is such that the internal supply voltage falls
below a preset limit, the by-pass relays will be automatically switched off.
This state is indicated by blinking of the phase loss led at 1.3Hz. Reset of the
supply L1, L2 and L3 is necessary to resume normal function.
