SAFETY PRECAUTIONS
ISUB is a new power electronic product, please read the operation manual carefully before using to keep
your safety and make sure proper operation.
In this manual, the safety precautions were sorted to “WARNING” and “CAUTION”.
！WARNING: Incorrect use may result in death or serious personal injury.
！CAUTION: Incorrect use may result in the damage of controller or system.
！WARNING
Do not dismantle or change the product, which may cause electric shock, fire hazard and personal injury.
Do not open the cover during the running of controller. Disconnect power and allow 5 minutes for the
internal capacitors to discharge dangerous internal voltage before working on controller and pump.
Ensure that the controller along with the pump as well as metal in proximity are adequately earthed.
Do not put wire, metal bar, filaments etc. into the controller as to cause a short circuit or get an electric
shock.
Do not splash water or other liquid over the controller.
！CAUTION
The controller and pump should be installed by suitably qualified technical personnel, and failure to
install in compliance with local standards may result in poor performance, equipment damage, fire and
electrical shock.
Do not perform high voltage insulation testing on the controller.
Never connect AC power to output UVW terminals.
The motor, controller and power specifications should be matching, otherwise it could cause abnormal
operation and damage the equipment.
If the controller has serious vibration, noise, heat or peculiar smell in the first operation, please cut off
the power immediately and contact customer service.
Do not install the controller in an environment with direct sunlight, rain, dust, frost or snow.
Warm reminder:
For convenience, the controller has set default with a nonzero AI1 Feedback Lost Detecting Value. If there
hasn’t been a pressure signal feedback into the terminal AI1, the controller will start up with failure and
display “E022”.
◇If the controller is a master, please connect a transducer to the controller and then press the STOP/RST
key;
◇If the controller is an auxiliary, it should be set as AI1 Feedback Lost Detecting Value (b02.08) 0 and then
press the STOP/RST key to reset error warning.

1.2 Description of Name Plate

3. ENVIRONMENTAL REQUIREMENT
3.1 Environment temperature range: -10℃~+40℃. Controller will be derated if ambient temperature exceeds
40℃.
3.2 Prevent rain drops, moist environment, oil fog, salt erosion, corrosive gas, etc.
3.3 Prevent direct sunlight, keep away from radiation source.
3.4 Prevent violent vibration or sudden impact.
3.5 Lower than 1000m installation altitude, it will be derated when the altitude is higher than 1000m.
CAUTION
When moving the controller please lift by its base and don’t lift by the panel. Otherwise may
cause the main unit fall off which may result in personal injury.
Install the controller on the fireproofing material (such as metal) to prevent fire.
When power off, should not install the controller until the power indicator light was
extinguished, which can ensure the device has been discharged completely.

4. WIRING
Figure 4-1- 1 wiring diagram
In order to keep safety and prevent electric shock and fire, PE must be grounded with ground resistance.
Ground wire should be big and short, and it is better to use copper wire (>3.5
2
mm
). Furthermore, reliable
grounding is the simplest, most effective and minimum cost solution for EMC problems, so it enjoys priority in
all EMC methods.

5. OPERATION
5.1 Keypad Description
Figure5.1 Keypad schematic diagram
5.2 Operation Procedure
5.2.1Power-on initialization
Firstly the system initializes during the controller power-on, and LED displays “b-603”. After the
initialization is completed, the controller is on stand-by status.
5.2.2 Parameter setting Three levels of menu are:1. Function code group (first-level); 2. Function code
(second-level); 3. Function code setting value (third-level)
▲At the primary interface, press <</SHIFT or >>/SHIFT will switchover display running/stop status
monitoring parameters;
▲At the primary interface, press PRG/ESC will enter the first-level menu then press PRG/ESC will return to
the primary interface;
▲At the first-level menu, press DATA/ENT will enter the second-level menu. In second-level menu can also
press PRG/ESC and DATA/ENT return to first-level menu or enter third-level menu;
▲At third-level menu, press both PRG/ESC and DATA/ENT can return to the second-level menu, difference
is: pressing DATA/ENT will save the parameters into the controller and return to the second-level menu
with shifting to the next function code automatically; while pressing PRG/ESC will directly return to the
second-level menu without saving the parameters, and keep staying at the current function code.
Example 1: Change factory pressure setting 3.0 bar to 2.5 bar Method 1:Enter parameter setting

Operation flow chart:
Figure 5-2-1 Operation Flow Chart
Method 2: Direct setting at the primary interface
Press △or ▽at primary interface, the system will switch over to display setting pressure, press △or ▽
again, the setting pressure increase/decrease, mean while the system trace the setting pressure. After
completing the pressure setting, please press DATA/ENT to save the value.
Example 2: During the running of controller, press <</SHIFT or >>/SHIFT to scroll through the parameters
in left or right order until there are two upper lights on, can check the feedback pressure value.

Transducer Range, input the max. range of connected transducer
b01.08
When display smaller than gauge, decrease b01.08;
When display greater than gauge, increase b01.08
Below need to set based on working conditioning and user’s requirement.

PID Parameter Debugging. Increase voltage stabilization accuracy or proper
regulation when Bias oversize and overwhelmed.
br07 group
Day-part water supply, set when needs the function. Reserved as Additive
Pipe Water Supply Mode, offering Day-part Variable Pressure Water Supply
and prevent insufficient net work pressure from affecting Public Water
Supply. Its’ setting refer to section 7.3.

8. FAULT AND TROUBLE SHOOTING
8.1 System Running Fault and Trouble Shooting
Abnormal Function
Reason
Solution
Can’t Sleep
1、Outlet Pipe Leakage；
2、Check Valve Leakage；
3、Pressure Tank Damage；
4、High Environment EMI；
5、Wrong Parameter
Check Outlet Pipe, or to set b04.04；
Inspect Check Valve；
Change Pressure Tank；
Transducer adopt shielded wires, Shielded
layer connect to PE；
Ensure b04.00＝1
Display Pressure Error
1、Detector Error；
2、Wrong Parameters；
3、Transducer Wires is too
long；
Adopt Standard Detector；
Calibration parameter b01.05，b01.08；
Avoid Use too Long Transducer Wires；
Full-Frequency running
1、Lose Pressure Feedback；
2、Wrong Parameter；
3、Pump Under power；
Check Transducer and Wires；
b05.02 should not be set as 1；
S2-Com should be open;
Set b07.14＝1, take a factory reset
Pressure vibration,
stabilize slow
1、PID Value unmatched；
2、Acc./Dec. Time too fast；
3、Big delay on pressure
feedback.
Tune PI value b02.03、b02.04
Tune Acc./Dec. time b05.03、b05.04
Avoid Use too Long Transducer Wires
Motor Noise
1、Motor Abnormal；
2、Motor installation is not
stable；
3、Low Carry-Frequency
Check Motor；
Proper turn up Carrier Frequency b05.08
