6.1VFD Parameter Settings For Use With

ROBERTS GORDON® ULTRAVAC™

The VFD parameters come with factory default set- tings. The following parameter settings must be changed for ROBERTS GORDON® ULTRAVAC™. Settings can only be altered when the pump motor is stopped.

Verify that there is power to the VFD (LCD display will be on) and power to the 24 V power switch on the relay board of the ROBERTS GORDON® ULTRA- VAC™ controller is off.

DANGER

Electrical Shock Hazard

Enclosure contains live electrical components.

Programming must be done by a trained technician only.

Replace cover before operating.

Failure to follow these instructions can result in death or electrical shock.

To override the rotary disconnect switch inside the VFD enclosure, turn the square rod with a wrench to the ON position. In order to be able to close the cover of the disconnect, the rods need to be turned back to the OFF position.

6.1.1

To enter the PROGRAM mode and access the parameters, press the Mode button. This will activate the PASSWORD prompt (if the password has not been disabled).

Display reads "00"

Upper right decimal point blinks

6.1.2

Use the arrow buttons to scroll to the password value (the factory set password is 225)

Press Mode to enter password

Once the correct password value is entered, the dis- play will read "P01", which indicates that the PROGRAM mode has been accessed at the begin- ning of the parameter menu (P01 is the first parameter).

P 01

NOTE: If the display flashes "Er", the password was incorrect, and the process to enter the password must be repeated.

6.1.3Use the arrow buttons to scroll to the desired parameter number. For new parameter settings See Page 28, Section 6.2.

6.1.4Once the desired parameter number is found:

Press Mode to display present parameter setting (example setting is 20.0).

Upper right decimal point blinks.

Use arrow buttons to change setting

Press Mode to store new setting and exit the program mode.

6.1.5To change another parameter, press the Mode key again to re-enter the PROGRAM mode (the parameter menu will be accessed at the parameter that was last viewed or changed before exiting).

If the Mode key is pressed within two minutes of exit- ing the PROGRAM mode, the password is not required to access the parameters. After two minutes,
