WARNING! The default operating mode when the unit is energized is OFF. If the parameter
ENABLE RESTARTS has been set to allow restarts, the unit will energize in AUTO mode. If the
external controls are calling for a motor run condition, the motor will start. Make sure either external
controls are off before energizing the input, or as soon as the unit has initialized, push the STOP/OFF
key until OFF appears on the display. Refer to Section 4, Using the Keypad and Display, for
instructions on operating the keypad.
6.3 Drive Set-up Procedure
If remote or automatic ON/OFF function is required, connect remote switch leads to the AUX1 and COM
terminals. An additional remote switch or jumper wire may be connected to the AUX2 and COM
terminals.
CAUTION: By default, AUX1 and AUX2 are programmed to be always in RUN mode. See
parameters AUX1 SELECT and AUX2 SELECT to change this setting.
1. If a Constant Pressure (CP) water system will be operated, connect the pressure sensors to the
appropriate control terminals. See Section 6.5, System Configuration and Section 7, Constant
Pressure Systems for details.
2. Apply power to the input terminals of the drive by turning on the input circuit breaker or disconnect
switch.
3. The graphic text display will scroll through several start-up sequence messages.
4. If the ENABLE RESTARTS parameter is set to allow restarts, the drive will initialize in AUTO mode
and the motor will run when control signals call for a motor run condition. In order to prevent the
motor from running at start-up, immediately after initialization, press the OFF/STOP key until OFF
appears on the display or open AUX1 to COM or AUX2 to COM.
5. Confirm that the unit has properly energized, and the display indicates the OFF mode.
6. Using the keypad and display, navigate to the Main Menu item, CHANGE PARAMETER VAULES,
to set the following parameters for basic operation (see Table 14 through Table 18 for details):
• INTERFACE PARAMETERS > SYSTEM CONFIG This parameter is critical to the operation of
the system. The default setting is for simple ON/OFF operation. See Section 6.5, System
Configuration, for complete information.
• OPERATING PARAMETERS > OVERCURRENT LIMIT This parameter sets the motor
overload protection. See Section 6.4, Motor Overload Protection for complete information.
• AUTO RESTART PARAMETERS > ENABLE RESTARTS This parameter enables the drive
to initialize in AUTO mode and to restart automatically after a fault. Factory default does not
allow auto restarts.
7. Push the MANUAL key until MANUAL appears in top left of the display for manual mode, then push
RUN to start the motor. In manual mode, the RUN/AUTO key will override an open AUX terminal or
other external control signal. Push the STOP/OFF key to stop the motor in manual mode.
CAUTION: In manual mode, pushing the RUN key will override all external control signals,
including constant pressure sensors. Be aware; dangerous pressure rise in closed plumbing
systems is possible when running in manual mode.
