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 may be connected to the AUX2 and
COM terminals. AUX2 SELECT must be set to 0 to use an additional switch.
CAUTION: By default, AUX1 is programmed such that OPEN=STOP, CLOSED=RUN
and AUX2 is programmed such that OPEN=RUN, CLOSED=STOP. When SYSTEM
CONFIG = 2 (Analog CP), AUX1 and AUX2 are programmed such that OPEN=RUN,
CLOSED=STOP. 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 or AUX2.
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 12 - Table 15 for details).
7. 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.
8. OPERATING PARAMETERS > OVERCURRENT LIMIT This parameter sets the
motor overload protection. See Section 6.2, Motor Overload Protection for complete
information.
9. 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.
10. 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.
11. The motor will start with the default acceleration ramp time of 0-30 Hz in one second,
then 30-60 Hz in ten seconds.
12. After initial power-up, use the keypad and display to navigate to CHANGE
PARAMETER VALUES to set any other adjustable parameters you wish to be
different from the factory defaults.
