3) SENSOR (2 parameters plus Reset):
Min Pressure (kPa):
The minimum pressure of the
transducer 0 kPa. The default is 0 kPa. Do not
change this value unless you are using a transducer
other than the one shipped with the drive, and the
transducer being used requires a different minimum
setting.
Max Pressure (kPa):
The maximum pressure of the
transducer 2000 kPa. The default is 690 kPa. Do
not change this value unless you are using a
transducer other than the one shipped with the
drive, and the transducer being used requires a
different maximum setting.
Reset to defaults:
Default value is NO. Change to
YES to reset all Sensor parameters to their default
values.
4) PIPE BREAK (2 parameters):
Pipe Break Detection:
Detects a possible leak in
the system. The Default value is ENABLED. Change
to DISABLE to disable Pipe Break Detection.
Number of days with no sleep:
The maximum
number of days that the drive will operate without
going to sleep. If the maximum is exceeded, the
drive stops the pump with a Pipe Break Fault.
Default is one day. Range is 1–24 days.
5) DRY RUN (5 parameters):
Auto Reset Delay:
The delay (in minutes) that the
drive will wait before attempting to restart after a
Dry Run Fault. Default is 10 minutes. Range is
3–60 minutes.
Number of Resets:
The number of times that the
drive will attempt to restart after a Dry Run Fault.
Default is 3. Range is 0–5.
Detection Time:
The amount of time the drive will
operate at less than 70 kPa. Default is 15 seconds.
Range is 5 to 600 seconds. For self primers,
increase value in the event of nuisance dry run
faults.
Fill Time:
The amount of time the drive will operate
in line fill mode. For self primers, increase value to
allow for priming. Default is 60 seconds. Range is
15 to 600 seconds.
Reset Window (Read Only):
The time window
allowed for resets after a Dry Run Fault. This is
calculated based on the values in the two
parameters above (Auto Reset Relay and Number
of Resets).
6) I/O (Two Submenus):
External Input (4 parameters
– see Figures 6 through 9,
Page 12).
NOTE:
An external device must be connected before
changing these parameters:
Unused:
The default.
Setpoint:
Used with devices like automatic
sprinkler systems that start and stop on a timeclock.
When the timeclock starts the system, SETPOINT
tells the drive to operate at the External Setpoint
pressure (under the Settings menu) until the
external device switches off.
External Fault:
Stops the pump and indicates
EXTERNAL FAULT. Used to alert the user to
problems with external devices.
Run Enable:
Used with external switches (for
example, float switches) connected to
I1
to allow
the drive to operate when the external switch is
ON, and stops the drive when the external switch
is OFF.
Relay Output (3 Settings—See Figures 6 through 9,
page 12):
Unused:
Selected when nothing is connected to
the O1 terminals.
Running:
Can turn an external device on or off
when the drive is running the pump.
Fault:
Can turn an external device (such as an
alarm or autodialer) on or off if the drive has a
fault.
Reset to Factory defaults:
Change NO to YES to reset all the parameters in the VFD
(including all sub-menus) to the factory-set default values.
NOTE:
This will display the startup menu. You must re-enter
the information required for startup (see “Initial Startup
Programming Procedure”, Page 8).
