Simplex Quick Start Procedure
15. Motor Rotation Test
14. This step checks the motor for proper direction and operation. This test is performed solely from the digital operator.
Apply power to the iQpump Micro after electrical connections are terminated and protective covers are installed.
At this point, D
DO NOT RUN THE MOTOR, The digital operator should display as shown in
Figure 3
.
Figure 3: Digital Operator
Refer to
Figure 1 or 2,
swap any ttwo
of the tthree output leads to the motor
(U/T1, V/T2 and W/T3). Repeat S
Step 8
and recheck motor direction after the
wiring change.
WARNING! Hazardous Voltage. Contact may cause electric shock or burn. Turn-off and lock-out system and facility power before servicing.
After the power has been turned OFF, wait at least five minutes until the charge indicator extinguishes completely before touching any wiring,
circuit boards or components.
Verify the transducer feedback signal level on the digital operator display matches a mechanical pressure gauge.
FEEDBACK SIGNAL LEVEL
Refer to parameter P1-02
and P1-03, if the feedback
device scaling or system
units are incorrect.
Press
and the HAND
LED should be
ON
.
The motor should be operating in the correct direction of pump.
Press

16. Feedback Signal Check
Refer to
Figure 1 or 2,
swap any
two of the tthree output leads to
the motor (U/T1, V/T2 and W/T3).
Repeat S
Step 8 and recheck motor
direction after the wiring change.
From HOME screen,
press to access “

” screen
.
“

” will display for
2 seconds, then automatically change to display the
feedback signal level.
17. AUTO MODE
Press the A
AUTO button to place the iQpump Micro into AUTO mode.
The AUTO mode will start and stop based on the Run Source Selection setting parameter b1-02. (Refer to Step 3) The
Reference Source Selection parameter b1-01 setting configures the AUTO mode reference source.
Press
to access or modify the system setpoint entered in parameter Q1-01 within the
18. SET SYSTEM SETPOINT
The iQpump Micro starts in AUTO Mode when the feedback signal level falls below the level programmed in parameter
P1-04 for the specified time in P1-05.
