Warning
Damage to the PCBA board may occur if related
requirements are not followed.
Ground the frequency converter to ensure personnel
safety and to reduce electromagnetic interference.
After disconnecting the AC drive from
the mains or from the DC input supply, wait until
the indicators on the cover go out. Wait an
additional 5 minutes before starting any work on
the connections of Inverter. After expiration of this
time, use measuring equipment to absolutely
ensure that no voltage is present. Always ensure
absence of voltage before starting any electrical
work!
Never work on the photovoltaic generator or
inverter and its input/output cables when the
inverter is connected to the mains or to the
photovoltaic generator.
Before performing any measurement on the
inverter, disconnect or isolate the mains supply

Steps of electrical connection:
•If the distance between the solar inverter and the motor is
longer than 50 meters, it is recommended to install the output
choke to avoid the frequent overcurrent protection and the
motor isolation damage. For models of choke, consult
Grundfos.
•Connect the DC output, AC input, AC output and the
communication wire to the males, and then plug them to the
females of the inverter. Tighten up to ensure the proper
connection.
AC input and output connections
Follow the below steps for the connecting AC cable.
•Unscrew the terminal of all components.

Quick key
The function of this key is determined by function code P07.02.
6.2 Keypad display
The display status of GI SPC series solar pump controller
keypads includes stop state parameter display, running state
parameter display, function code parameter display, fault
and alarm state display.
6.2.1 Stop state parameter display
When the pump controller is in the stop state, the keypad
displays stop state parameters. The stop state parameters
displayed by default parameter such as the set frequency,
bus voltage, input and output state. Press >>/SHIFT to shift
the display of the selected parameter from left to right.
6.2.2 Running state parameter display
After receiving a valid running command, the pump
controller enters the running state and the keypad displays
the running state parameters. The RUN/TUNE indicator on
the keypad is on, while the state of FWD/REV is determined
by the current running direction.
In the running state, the parameters displayed by default
include the running frequency, set frequency, bus voltage,
output voltage, output current, and pump rotating speed.
Press >>/SHIFT to shift the display of the selected parameters
form left to right and press QUICK/JOG (P07.02=2) to shift
from right to left.
6.2.3 Fault state display
If the pump controller detects a fault signal, it enters the
fault pre-alarm display state. The keypad displays the fault
code and the TRIP indication on the keypad is on. When a
fault occurs, the pump controller attempts to perform auto
reset for five times by default. If the fault persists, the fault
code remains displayed. The user can reset the pump
controller through the key, control terminal, or
communication command.
6.2.4 Function code editing state display
In the state of stopping, running or fault, press
to enter the editing state (if there is a password, see P07.00).
The editing state is displayed on two levels of menu and the
order is: function code group/function code
number→function code parameter.
Press DATA/ENT to enter the function parameter display
state. In this state, press to save the parameter settings or
press PRG/ESC to exit.

6.3 Keypad operation
Operate the pump controller via operation panel. For the
detailed structure description of function codes,
see section 7.
6.3.1 Function code modification.
The PV pumping inverter has three levels of menus, which
are:
• Group number of function code (first-level menu)
• Tab of function code (second-level menu)
• Set value of function code (third-level menu)
Press both the PRG/ESC and the DATA/ENT can return to the
second-level menu from the third-level menu. The difference is that
pressing PRG/ESC will save the parameter settings into the control
panel and then return to the second-level menu and shift to the
next function code automatically, while pressing PRG/ESC will
directly return to the second-level menu without saving the
parameter settings and keep staying at the current function code.
Under the third-level menu, if the parameter is not blinking, it
means the function code cannot be modify. The possible reasons
could be:
• This function code is not modifiable parameter, such as actual
detected parameter, operation records and so on.
• This function code is not modifiable in running state but
modifiable in stop state.
Example: Set function code P00.01 from 0 to 1.
Fig. 33 Parameter modification
Press and to modify the value.
6.3.2 Password Setting
GI SPC series pump controller provide password protection
function to users.
Set P7.00 for the password protection. Press PRG/ESC for the
function code editing state, "0.0.0.0.0" will be displayed. Set the
required password.
Set P7.00 to 0 to cancel password protection function.

This parameter is used to set the lower limit running frequency of the pump
controller.The inverter runs at the lower limit frequency if the set frequency is
lower than the lower limit.

Note : Modify the function code to shift the rotation direction of the motor. This effect
equals to the shifting the rotation direction by adjusting either two of the motor lines
(U, V and W). The motor rotation direction can be changed by QUICK/JOG on the
keypad. Refer to parameter P07.02.

0: Decelerate to stop
The pump controller decelerates to reduce the output frequency during the set

V/F Curve
Setting
These function codes define the V/F curve of motor to meet the need of different
loads.
0: Straight line V/F curve, applying to the constant torque load
1: Multi-dots V/F curve
2: 1.3th power torque-stepdown V/F curve
3: 1.7th power torque-stepdown V/F curve
4: 2.0th power torque-stepdown V/F curve
Curves 2–4 apply to the torque loads such as fans and water pumps. Users can
adjust according to the features of the loads to get the best performance.
5: Customized V/F (V/F separation) in this mode, V can be separated from f and f
can be adjusted through the frequency given channel set by P00.06 or the voltage
given channel set by P04.27 to change the feature of the curve.
Note: Vb in the below picture is the motor rated voltage and fb is the motor rated
frequency.

Torque boost
• Torque boost is for the output voltage for the features of low frequency torque.
P04.01 is for the Max. output voltage Vb.
• P04.02 defines the percentage of closing frequency of manual torque to fb.
• Torque boost should be selected according to the load. The bigger the load is, the
bigger the torque is. Too big torque boost is inappropriate because the motor will
run with over magnetic and the current of the pump controller will increase to add
the temperature of the pump controller and decrease the efficiency.
• When the torque boost is set to 0.0%, the pump controller is automatic torque
boost.
• Torque boost threshold: below this frequency point, the torque boost is valid, but
over this frequency point, the torque boost is invalid.

Note: V1＜V2＜V3, f1＜f2＜f3. If the low-frequency voltage is high,
overtemperature and burning may occur and the overcurrent stall and protection
may occur to the solar pump controller.

This function code is used to compensate the change of the rotation speed caused
by load during compensation SVPWM control to improve the rigidity of the motor.
It can be set to the rated slip frequency of the motor which is counted as below:
△f=fb-n*p/60 Of which, fb is the rated frequency of the motor, its function code is
P02.02; n is the rated rotating speed of the motor and its function code is P02.03; p
is the pole pair of the motor. 100.0% corresponds to the rated slip frequency △f.
