PDM30 Series
Installation
Hold the bottom of the SPD when install or move the SPD, cannot just hold the shell to
prevent the injured or broken SPD.
SPD must be far away from heat source, flammable and explosive objects, and installed on
metal or other nonflammable objects.
If the SPD is mounted in a protective cabinet, the cabinet need to set vents to ensure ambient
temperature is below 40℃; otherwise it may be damaged because of high temperature.
Wiring
Ensure only qualified personnel to operate. Otherwise it can cause an electrical shock or
damage of the SPD.
Make sure the SPD is isolated from power supply by the circuit breaker. Otherwise it may
cause a fire.
Make sure that the ground terminal

is grounded correctly. Otherwise it can cause an
Please do not touch the main circuit terminal, and the main circuit terminals of the SPD do
not contact the shell. Otherwise it may cause an electrical shock.
Before connecting, make sure that the SPD rated voltage, phase number confirm to input
voltage, phase number; Otherwise it may cause fire or personal injury.
Never connect the AC input power supply to output terminals V, U, W; Otherwise the SPD
will be damaged and the guarantee is invalid.
Never perform with stand voltage test of the SPD, otherwise it may cause a damage to the
SPD.
The main circuit wiring of the SPD and the control loop wiring should be separated or

vertical crossed, otherwise it will make the control signal interference.
The cable connected to the main circuit terminals should be use lugswith isolated casing.
If the length of cable between the SPD and the motor is more than 50 meters, it is
recommended touse a output reactor to protect the SPD and motor.
Run
Turn on the input AC power only after the front cover is put correctly; Do not open or
remove the front cover when operation. Otherwise it may cause an electric shock.
If the function fault automatic reset or restart after power failure had been set, a safety
measures should be taken in advance; otherwise it may cause damage or injury.
The key “RUN/STOP” may be lose efficacy because some function had been set, a separate
emergency power switch can be installed in the SPD control system; otherwise it may cause
damage or injury.
When the SPD is power on, the SPD terminal is still live even in stop state, do not touch,
otherwise there is a risk of electric shock.
Do not use circuit breaker to control the stop or start of the SPD; Otherwise it may cause
damage to the SPD.
Because the SPD speed from low to high that is in a very short time, make sure that the
motor and equipment are in the permitted range to use. Otherwise it may cause damage to
the equipment.
Do not touch the heat sink. Otherwise it may cause harmful burns
The factory parameters of the SPD can meet most requirements of equipment operation, if
not necessary, please do not modify the parameters. Even though some equipment has
special needs, only necessary parameters can be modified. Otherwise, random
modifications may cause damage to the device.

PDM30 Series
Maintenance and check
When power on, do not touch the connection terminals. Otherwise it may cause an
electrical shock.
Only qualified electrical engineering personnel can maintain, replace and inspect the SPD.
Wait at least 10 minutes after the power failure, or make sure that is no residual voltage
before carry out maintenance and inspection, otherwise it may cause damage.
PCB board has CMOS integrated circuit, do not touch, otherwise the static electricity may
damage PCB board.
Others
It is strictly forbidden to transform the SPD, otherwise it may cause casualties. After
arbitrarily changing SPD, the guarantee will be invalid.

1.3 Operation and display mode
(1) Status display mode:
When power on the SPD, it enters the status display mode. When it stops, it
displays pressure setting. Press "+" or "-"to modify pressure setting. When it is
running,it displays current pressure, operating frequency, and setting pressure.
Press the "+" or "-" to switch the display; press "MENU" for two seconds to enter
the parameter setting mode.
(2) Parameter setting mode:
To view or set the parameters, as starting from status display mode, press the
"MENU" for 2 seconds to enter the parameter setting mode, and then press the
"RUN / STOP" starts to set parameters. After you set the parameter press twice
"MENU" to exit parameter setting mode, and return to the status display mode.
(3) The alarm display mode:
Automatically enter this mode when a drive fault or warning arises; press the
"RUN / STOP" to reset, or it can automatically restored the previous mode after
the alarm is eliminated.
1.4 Menu Operation
Three-class menus are:
① Function group (first class)
② Function code setting(second class)
③Function code setting(third class)
- 9 -
PDM30 Series
Instruction: In the third class menu, pressing “MENU” or “RUN/STOP” can return
to the second class menu. The difference is that pressing “RUN/STOP” first saves
parameters to control board, and then returns to the second class menu and shifts to
next function code automatically; pressing “MENU” returns to the second class
menu directly without saving parameters and keeps staying at current function
code.
Under the third class menu, only flicker bit can be modified. Revisable bit will
shift automatically after 5 seconds.
Note: For parameters marked with “●”, please modify them in stopped state.
Parameters marked with “◎” are actual detected and recorded values which can’t
be modified.

P0-03 is the range of the sensor. Common range is 1MPa, namely 10.0bar.
P0-00 is the pressure value of the pipe network. If P0-00=3.0bar, after the smart
pump drive is started, the pressure of the pipe network keeps constant at 3.0 bar.
General sensor is in current type. The wiring method of SPD is similar to
pressure transmitter, connected to AI terminal as pressure feedback: if voltage
sensor is use, please modify P0-04 to 0. The wiring method of SPD is similar to
transmissible pressure gauge, connected to AI terminal as pressure feedback.
When feedback value is smaller than or equal to set pressure minus PID start
pressure（P0-00～P0-01）, and it holds the state in P0-10 set time, PID adjustment
will be restarted. For example, when P0-00=3，P0-01=0.3，P0-10=5.0, if feedback
value is smaller than or equal to 2.7, and the time is longer than 5s, PID adjustment
will be restarted. Once it is larger than 2.7, the time will recount.

The larger the parameter, the faster the response

according to different water supply system.
Adjustment method:
If factory parameters can’t meet demands, adjust parameters finely. First increase
proportional gain to make sure that the system will not oscillate.
Note: improper parameter setting of P0-06 will cause huge speed overshoot, and
even over voltage fault in overshoot back.

PDM30 Series
After selecting sleep mode 1 by parameter P0-08, the SPD will detect whether
feedback pressure is higher than set pressure. If yes, the SPD will start sleep
detection. After PID sleep detection delay set by P0-09, if feedback pressure is still
higher than set pressure, SPD will decrease output frequency gradually to sleep
detection low level hold frequency set by P0-11. After sleep detection low level
hold frequency waiting time, if feedback pressure is still higher than set pressure,
the SPD decreases output frequency to 0Hz and enter standby. If in above process,
feedback pressure is lower than set pressure, the SPD will judge as invalid sleep
detection and come back to PID adjustment status.
After the SPD enters standby, if feedback pressure is lower than PID sleep
threshold, SPD will start wakeup detection. After PID wakeup detection delay set
by P0-10, if feedback pressure is still lower than wakeup pressure threshold,
wakeup is successful and SPD comes back to PID adjustment status; else, wakeup
fails. Too high PID sleep threshold may cause frequent start and stop of the SPD.
Too low PID sleep threshold may cause deficient pressure.
Notes: sleep holding frequency of different water supply system is different. When
there is no water outside and the water tap is turned off, but the pump is still
running, increase P0-11 to sleep holding frequency.

Following methods can realize water shortage protection by default:
（1）The switch of water shortage protection is turned on（P0-25=X）;
（2）The feedback pressure is less than allowed threshold value of water shortage
detection(feedback pressure<P0-26);
（ 3 ） The current running frequency is no less than water shortage protection
detection frequency（running frequency>=P0-27）;
（4）When （1）-（3） are satisfied, timing starts. When the time meeting the
condition exceeds abnormal pressure alarm delay time (delay time>P0-29), water
shortage fault will be reported. When either condition is not satisfied during timing,
timing recounts.
When water shortage fault is reported, after the time set by P0-30, the drive will
reset. By setting the next following parameters:

PDM30 Series
Use inflow detection pressure to reset water shortage faults directly.
Note:When judge water shortage according to pressure, because the working
condition of each drive is different such as range of load size, only setting the
value of P0-28 reasonably according to site conditions can it make correct
judgment to water shortage.
Setting method: Run the drive. When running frequency reaches maximum
frequency, turn off inlet and record the output current displayed on the drive.
Divide this current by P1-16 (the rated current of the motor) to get a percentage.
Make the value of P0-28 a little higher than 5-10 percentage points of the
percentage. Too high value of P0-28 will lead to false water shortage report in
normal operation. Water shortage protection will not work effectively with too low
value of P0-28.

Use P1-08 to choose running status of SPD when running frequency is lower than
lower limit frequency. To prevent motor from being in low speed operation for a
long time, you can use this parameter to stop it.
If use a 60Hz pump, please set parameters according to the following steps.
Step 1: Set the parameter P1.06 (Upper limit frequency) to 60
Step 2: Set the parameter P1.13 (Motor rated frequency) to 60

Use this parameter to adjust carrier frequency of SPD. You can decrease motor
noise by adjusting carrier frequency, avoid point of resonance, decrease leakage
current of wires to ground and decrease interference of SPD.
When carrier frequency is high, motor loss decreases, temperature rising of motor
is small, but SPD loss increases, temperature rising of SPD increases and
interference increases.

smaller than or equal to feedback broken line detection, system starts detection
timing. When detection timing exceeds feedback broken line detection time,
system will report PID feedback broken line fault.
Please set according to parameters of the motor nameplate.
To guarantee control performance, please configure motor according to standard
adaptive motor of drives. If there is big difference between motor power and
standard adaptive motor, control performance of drives will decrease obviously.

5.2 Common Faults and Actions
The following faults may happen in use. For brief fault analysis, please refer to the
following methods.
5.2.1 No display at power on
(1) Check whether the input power is consistent with the nominal voltage of the
drive with multimeter.
(2) Check whether the three-phase rectifier bridge is intact. If the rectifier bridge is
broken down, please request service.
5.2.2 The power air switch trips off at power on.
(1) Check whether there is short circuit or ground connection between input power.
If yes, please eliminate it.
(2) Check whether the rectifier bridge has been broken down. If yes, please request
service.
5.2.3 The motor doesn’t rotate after the SPD runs.
(1) Check whether there is balanced three-phase output among U, V,W. If yes,
check whether the motor is broken or blocked. If no, please confirm whether the
motor parameters are set correctly.
(2) If there is output but the three-phase power is not balanced, please request
service.
(3) If there is no output voltage, please request service.
5.2.4 SPD shows normally at power on but the power air switch trips off after
running.
(1) Check whether short circuit occurs between output modules interval. If yes,
please request service.

(2) Check if there is short circuit or ground connection between motor leads. If yes,
please eliminate it.
(3) If switch stripping off occurs occasionally and the distance between motor and
inverter is far, consider to add output AC reactor.
5.2.5 It doesn’t stop in no water use.
(1) Check whether the feedback pressure displayed on the SPD board is no less
than set pressure. If the feedback pressure is less than set pressure, please check
whether the range of the pressure sensor is set correctly, whether the pump rotates
reversely, whether there is air and whether the inlet is blocked by sundries.
(2) If the feedback pressure is no less than set pressure, please decrease the set
value of P0-09 and increase P0-11.
(3) If feedback pressure changes nearby set value, stop the SPD manually and see
whether the pressure decreases. If yes, check valve needs to be changed.
5.2.6 It can’t sleep in small amount of water use or leakage
(1) If it can’t sleep or the sleep time is too long, decrease P0-09 and increase P0-11,
If it is still not effective, increase P0-31.
(2) If it sleeps in advance, first increase P0-09. If it is still not effective, decrease
P0-20.
(3) If it starts and stops frequently, first increase P0-09. If it is not effective,
increase P0-20. If it is still not effective, increase P0-01.
5.2.7 It can’t stop to make protection in water shortage.
(1) Water shortage protection switch P0-25 is not enabled.
(2) The threshold value of water shortage detection P0-26 is set too low.
(3) The current percentage of water shortage detection P0-28 is set too low.
