Product Description
The RSHP Flexy is a micro-
processor-based softstarter
for 3-phase induction motors
in a compact new format.
While offering versatile ramp-
ing features, Flexy is also very
easy to configure. It is possi-
ble to match the start/stop
ramping profiles with the
functional requirements of
specific motor loads. A clever
push-button and LED user
interface eliminates the added
cost of an alphanumeric dis-
play. The RSHP Flexy uses an
in-house designed system
that ensures efficient power
management.

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.
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
to the coil of an external

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
:
A phase loss on L1 or L2 causes the device to reset as these phases
provide the internal power supply.
Note 4: Phase sequence and phase loss alarms are only detected if they occur
during power up, when L1, L2, L3 are switched ON.
Note 5: 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 6: 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.

To save and exit Level 2
selection procedure, press
and hold SELECT until the
parameter LEDs scroll down
twice.
Running with the cus-
tomised ramp:
After Level 2 procedure has
been completed the device will
store the parameters in posi-
tion 10. The bargraph LED in
position 10 will light up contin-
uously during operation.
Defaults:
Enter Level 2 mode as previ-
ously described. When the
bargraph LED is flashing,
press and hold the UP and
DOWN arrow buttons simulta-
neously until the parameter
LEDS scroll twice. This resets
all the ramp settings to factory
default.
Attention!
If no button is pressed for
several seconds during Level
1 or Level 2 procedures, the
product goes out of the Level
setting mode back to the pre-
vious ramp parameter combi-
nation.
Factory DEFAULT - Plug and
Play
The ramp selector is set to
bargraph position 1, accord-
ing to Table 1: "Level 1
Parameters".The product will
be shipped with this standard
ramp setting. If this setting is
considered suitable, no other
settings are required.
Level 1 - FACTORY PRE-
DEFINED RAMP PARAME-
TERS
For this mode, the 3-phases
L1,L2,L3 must be present but
control A1,A2 must not be
present. In this level, the user
may select from 10 pre-
defined ramps by selecting
one of the 10 bargraph posi-
tions: 1,2,3........9 or 10,
according to Table 1: "Level 1
Parameters". Position 1 is the
same as the factory DEFAULT
described above. In each pre-
defined ramp, the values for
all parameters (ramp up, ramp
down, initial torque, kickstart,
ramp up shape and ramp
down shape) are fixed by the
factory against each bargraph
LED position. Position 10 is
factory set for "High Torque
Load" (see Table 1) but can be
re-programmed according to
Level 2 instructions. The bar-
graph LED will remain ON at
the selected position during
operation as long as L1,L2,L3
are present, to show which
ramp parameters are being
used.
To enter Level 1 mode:
Press SELECT once. One bar-
graph LED will start flashing at
the position that has been
previously programmed (posi-
tion 1 if the product is just out
of the box).
To select the factory pre-
defined ramp:
Use the UP and DOWN arrow
buttons to move the flashing
LED up or down on the bar-
graph.
To save and exit Level 1
mode:
To fix the new settings, press
SELECT. This stores the
selected ramp position and
causes the device to exit
Level 1. The bargraph LED
remains ON at the selected
position during operation as
long as L1,L2,L3 are present.
(If no button is pressed for
several seconds, the device
goes out of this setting mode
automatically and above
steps must be repeated).
Level 2 - RAMP CUSTOMI-
SATION
In this level, a new combina-
tion of parameters settings
(ramp up, ramp down, initial
torque, kickstart, ramp up
shape and ramp down shape)
can be made that is not
included in the pre-defined
ramps of Level 1 (In Level 1
these settings have been fixed
by the factory. See Table 1:
Level 1 Parameters).In Level
2, each parameter of "position
10" can be re-defined individ-
ually by first selecting the
parameter and then setting
the bargraph level in accor-
dance with Table 2: "Level 2
Parameters".
To enter Level 2 mode:
Press SELECT and move
flashing bargaph LED to posi-
tion 10. With the bargraph
flashing at position 10, press
and hold SELECT until the
parameter LEDs scroll down
twice. The Ramp Up LED will
light up. Press SELECT and
one bargraph LED will start
flashing. Position 10 parame-
ters can now be redefined.
To re-define position 10
parameters:
The Ramp up parameter LED
must be flashing. The bar-
graph LED must be flashing at
the position that has been
previously programmed (posi-
tion 7 if the product is just out
of the box). Use the
UP/DOWN arrow keys to
move the flashing bargraph
LED to the required position
according to Table 2: "Level 2
Parameters" and then press
SELECT. The next parameter
LED (Ramp down) will start
flashing to indicate that it can
be adjusted.
The bargraph LED will also
start flashing at the position
that has been previously pro-
grammed (position 7 if the
product is just out of the box).
Use the arrow keys to move
the flashing bargraph LED to
the required position accord-
ing to Table 2: "Level 2
Parameters" and then press
SELECT. These steps are
repeated until all parameters
have been set. Ramp shapes
can be selected in the same
