supplement to other documentation supplied with this equipment and will guide the user in properly wiring the iQpump and motor. It will also show the user how to configure the iQpump for a simplex pump application.

Danger:

Improper wiring can and will cause bodily harm as well as damage to the equipment.

When installing the system, be sure to follow good wiring practices and all applicable codes. Ensure that the mounting of the various components are secure and that the environment, such as extreme dampness, poor ventilation, etc. will not cause system degradation.

· Check that the available power will meet the requirements.

· Ensure that the compatible with the pump motor requirements.

· In the case of systems with more than one iQpump, follow the above procedure for each iQpump and pump motor.

The mounting of the iQpump is extremely important regarding environment and accessibility. Depending on your system, there are various models available and the mounting dimensions (footprint) may be different. Because the mounting procedure is fairly extensive, it is beyond the scope of this document; the user is referred to the iQpump User Manual (Document No. TM.iQp.06) received with the iQpump, that you received and follow the procedure described in the manual to ensure a safe and functional installation. In cases where the system has more than one iQpump, refer to the proper clearances required for adequate ventilation.

pay particular attention to:

· The clearances to be maintained around the enclosure for adequate ventilation.

· The environmental specifications such as avoiding excessive dampness, extreme temperatures, chemical exposure, corrosive areas, etc. to avoid damage to the equipment and to maintain safety.

Improper removal of the iQpump terminal cover as well as front cover can cause extensive damage to the iQpump. To avoid damage to these items, please pay particular attention to the iQpump User Manual, Document No. TM.iQp.06, Section 1.8, R

Please read this cheat sheet and other documentation provided with the iQpump thoroughly

Pump Quick Setup

In this step, the iQpump is setup for a simplex pump application using the Pump Quick Setup menu. Apply power to the iQpump after all the electrical connections have been made and the terminal cover has been re-attached. At this point DO NOT RUN THE MOTOR the digital operator should be reading as shown below in Fig. 3.

Next, push 2 times on the digital operator until

the digital operator shows the Pump Quick Setup Main Menu.

Next press to start

the Pump Quick Setup procedure.

The Pump Quick Start Menu consists of the most important parameters to setup your iQpump for use with your pump system.

Press to access a parameter, and use

to select the digit and use to change the

parameter value.

Press to save the value.

IMPORTANT: Enter service factor amps (SFA) when using an iQpump with a submersible pump motor.

Press to go to the next parameter to continue the Pump

Quick Setup programming. When Quick Setup is completed, press

to exit the Pump Quick Setup menu and go to operation.

Enter ’4’ for an 1800 RPM motor and ‘2’ for a 3600 RPM motor.

Feedback Device Scaling

System Scaling: Enter feedback device maximum:

Example: Enter 200 for pressure transducer with a maximum of 200 PSI at 20mA.

When the iQpump is turned On and the feedback signal level (transducer) falls below this

level, the pump system will start after the time specified in P1-05 (default 1 sec).

Programming the Start Level as an Absolute Value

Start Level has to programmed to a positive value in order for the Start Level to be an

absolute value. Example: Start Level P1-04 set to 50 PSI and delay time P1-05 set to

5 sec. Pump system will start when the pressure drops below 50 PSI for 5 sec.

Programming the Start Level as a Delta Level from the System Set-Point

Start Level has to programmed to a negative value in order for the Start Level to be a

delta value from the set-point.

Example: Start Level P1-04 set to –10 PSI with a system set-point of 50 PSI and a delay

time P1-05 set to 5 sec. Pump system will start when the pressure drops below 40 PSI

(50 - 10) for 5 sec.

For submersible motors use service factor amps (SFA).

Confirm number of poles

2 Pole Motor = 3600 RPM

4 Pole Motor = 1800 RPM

6 Pole Motor = 1200 RPM

8 Pole Motor = 900 RPM

Confirm feedback device scaling.
