3.2.4 Connection and use of control terminals
（1） Wiring preparation
If the user uses the external terminal, it is recommended to use the shielded wire
from the terminal row, the shield wire should be connected to the earth.
In order to avoid the interference of electromagnetic interference, the control lead
should avoid the motor cable and other inductive electrical wiring
（2） The connection of the outer terminal x1
The 14 terminal is located at the bottom of the starter, with a dangerous voltage
when it is used, and the power must be disconnected before disconnecting
● Bypass relay terminal 1,2
When the start-up process is completed, the built-in contacts will be closed, so that
the bypass contactor km closed; and when the stop command is issued, the built-in
contacts will open (see Figure 3.4)
It is suggested that the two ends of the coil of the contactor are connected with a
series circuit of resistance capacitance, which is beneficial to absorb the peak voltage
generated when the contactor coil is broken, and reduce the interference to the control
circuit of the starter

7.1 HHS Modbus Protocol Part
This section describes how to use Modbus communication to control the various operations of
HHS
7.1.1 Overview of Modbus
Modbus is a serial asynchronous communication protocol. The physical interface for
rs485.modbus is designed for Modicon PLC, with PLC structure characteristics of the. Modbus in
the network control, HHS can be likened to a soft starter PLC to read and write. HHS will start stop
control, state information (fault current, etc.) to keep register area and function parameter mapping
(4xxx). Through the use of PLC to read and write control of the master station.

Send code 02 03 01 13 00 01, return to 02 03 02 00 03, read the protection level of 3
Example 3 rewrite the soft starter function code 02 (limiting current) to 250%
The host sends the code 02 06 01 02 00 FA, HHS returns the code to 02 06 01 02 00 FA; if
returns the 02 86 03 to indicate cannot write, possibly the starter is running
Example 4 the function code 09 is stored at a value of about 10 times, such as the read function
code number (Jump time)
Send code 02 03 01 09 00 01, return of 02 03 02 00 03, read the Jump time is 3, the actual
value of 0.3s. is the contrary, write Jump time 0.3s, just send the 02 06 01 09 00 03

7.1.5 Precautions for use
（1）The address of the HHS (function code 16) must be in accordance with the control address
of the controller; the baud rate (function code 17); even-odd check (function code 18) is the
same as the controller; the parameter must be reset to power up
（2）If not receiving the response data, the parameters should be set to check the above, the 485
terminal connection is correct, the CRC effect is correct.
（3）More than one HHS communication, should be at the end of the last AB on both ends of the
120 ohm resistance

Chapter 8 HHS use precautions and routine
maintenance
8.1 Precautions for use
z
Prevent electric shock
The input power of HHS soft starter, when the load or open phase, even in the stopped
state, its output will still have a very high voltage induction. The output end of the no contact of
the soft starter, otherwise there will be the risk of electric shock.
HHS soft starter control circuit board with 380V voltage, the electric shock risk when
debugging
z
Induction voltage
Induction voltage soft starter HHS output at no-load is normal phenomenon, does not
affect the use of induction voltage by leakage of SCR (silicon controlled rectifier, GTR, IGBT
and other solid-state semiconductor devices have different degrees of leakage) exchange
pathway and dv/dt resistance capacitance filter loop. Voltage meter to zero measurement,
about 100~220v (related to the internal resistance of the voltmeter). The induction voltage of
load capacity is very small, disappeared in the output connection after load.
z
Compensating capacitor
The reactive power compensation capacitor used to improve the power factor must be
connected to the input of the HHS soft starter, not to be connected to the output, otherwise it
will damage the SCR power device in the soft starter
z
Meg-ohmmeter
The insulation resistance between the input and output of the HHS soft starter shall not
be measured with the Meg-ohmmeter, otherwise the thyristor and the control board of the soft
starter may be damaged due to excessive pressure
HHS can be used to measure the soft phase of the soft starter and relatively insulated,
but should be in advance with three short lines will be the three-phase input and output
shorted, and unplug all the plugs on the control panel
Measurement of motor insulation, should also follow the above principles
z
Input and output
Do not connect the input and output terminals of the main circuit of the HHS soft starter,
otherwise it will result in the unintended action of the soft starter, which may damage the soft
starter and the motor
- 48 -
z Bypass phase sequence
When the bypass contactor is used, the phase sequence of the starting circuit should be
consistent with the phase sequence of the bypass circuit. Otherwise, the bypass switch will
cause an interphase short circuit, which will cause the air circuit breaker to trip or even
damage the equipment
z Low voltage level
Terminals 7,8,9,10,11 shall not be connected to other external power sources on the
terminals, or they will damage the internal circuit of the soft starter
z Soft starter voltage rating
Terminals
13,14 use external AC380V operating voltage, not on these terminals
connected to other voltage rating power supply, otherwise it will damage the internal circuit of
the soft starter
8.2 Daily maintenance of soft starter
z Dust content
If there is too much dust, the insulation level of the soft starter will be reduced, and the soft
starter may not work properly
a.primary circuit creepage, pulling arc, hazard equipment;
b.two circuit leakage, short circuit, control failure;
c.heat sink thermal resistance, SCR temperature rise
z Cleaning dust
a.clean and dry brush gently brush the dust;
b.use compressed air to blow away the dust
z Dew condensation
If frosting, the insulation level of the soft starter will be reduced, and the soft starter may not
work properly
a.primary circuit creepage, pulling arc, hazard equipment;
b.two circuit leakage, short circuit, control failure;
c.aggravates seat corrosion of metal parts
z Drying up
a.With electric or electric stove drying;
b.Wwet distribution room
