Motor Rotation Test
In this step the motor is checked for proper direction and operation. This
test is to be performed solely from the digital operator. Apply power to the
iQpump after all the electrical connections have been made and protective
covers have been re-attached. At this point, D
DO NOT RUN THE MOTOR,
the Digital Operator should display as shown in Fig. 3.

Use precaution, and refer to
Fig.1 or 2, swap any two of the
three output leads to the motor
(U/T1, V/T2 and W/T3). After the
wiring change, repeat
Step 8
and recheck motor direction.
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.

FEEDBACK SIGNAL CHECK
FEEDBACK SIGNAL LEVEL
Refer to parameter P1-02 and P1-03, if the
feedback device scaling or system units are
incorrect.
Next, push
and the HAND LED should be ON.
The motor should now be operating at in the correct direction of pump.

9 Auto Mode Operation
AUTO MODE
Press the A AUTO button to put the iQpump into AUTO mode.
In AUTO mode the iQpump is capable of starting or stopping based on the Run Source
Selection setting parameter b1-02. (See Step 3 Select Start/Stop Control Method) The
setpoint used in AUTO mode is based on the Reference Source Selection setting
parameter b1-01. (See Step 3 Select Speed Method)
The iQpump can be operated in AUTO mode when the following actions have been
performed:
·
All parameters are programmed
· Motor direction has been checked
· Auto Mode: Reference source selected in parameter b1-01 (See step 3)
· Auto Mode: Run source selected in parameter b1-02 (See Step 3)
Next, press to access or modify the system setpoint that was entered using
SET SYSTEM SETPOINT
iQpump automatically starts in Auto Mode when the feedback signal level falls below
the programmed level in parameter P1-04 for the specified time in P1-05.
Use to select the digit and to change the system setpoint.
Next press
Next, press the A AUTO
button to start the
iQpump.

Sleep and Anti-No-Flow (ANF) Detection
NOTE: Before adjusting Anti-No-Flow operation ensure your system is regulating satisfactory while operating under
normal running conditions.
If stable continue to Step 1 to verify no-flow/sleep operation. If unstable turn off the Anti-No-Flow function
(P2-23 = 0.00%) and adjust the PI control parameters b5-02 and b5-03 to stabilize pump system. Refer to iQpump
Quick Start Guide (Document No.TOEP YAIP1W 01) for additional information. Once the system is stable, re-
enable the Anti-No-Flow function by setting P2-23 to 0.40% and continue to Step 1 to verify no-flow/sleep
operation.
Step 1: Verify system holds pressure by creating a no-flow situation (e.g. close off discharge valve).
Step 2: Press OFF button on the digital operator, wait 1 min. until system stabilizes and verify system pressure
feedback U1-91. If the pressure drops more than 3 PSI (U1-91) adjust P2-25 to the actual delta pressure drop plus
1 PSI.
Example: Setpoint is 80 PSI, pressure feedback U1-91 shows 76 PSI, P2-25 should be 4 + 1 or 5 PSI.
Note: This value should always be more than your start level (P1-04). If not, the system pressure is not holding and
this needs to be corrected, or the pump system will continue to cycle on and off.
Step 3: Run system in normal automatic operation with flow. Next check monitor
U1-99 “ANF Timer” and verify that the value is incrementing and resetting back to zero continuously. If the value
holds at 10 sec. (P2-24) increase P2-24 “Anti-No-Flow Detection Time” by increments of 5 sec. Repeat Step 3 each
time P2-24 is adjusted.
Step 4: Create a no-flow situation (e.g. close discharge valve) and monitor that U1-99 “ANF Timer” increments and
holds at P2-24 time (value set in Step 3). Once the Anti-No-Flow timer expires the speed will reduce gradually until
it reaches minimum pump speed (P1-06) where it will hold for 5 sec. (P2-03) before going to sleep.
Step 5: Run system in normal automatic operation and verify sleep and wake-up operation until system performs
satisfactory.

The iQpump can be operated in HAND mode when the following actions have been performed:
·
All parameters are programmed
· Motor direction has been checked
