BR-10 Frost Protection
Frost protection protects the pump against the cold weather during winter. When the set time is
elapsed, the pump operates under the maximum frequency for 5 seconds, and then stops.
BR-11 Lock parameters
This function locks and initializes the program.
0: Change of parameters is allowed
1: Change of parameters is not allowed
2: Initializes the parameters to factory default values.
BR-12 Firmware version
This displays the firmware version of the program. To improve the performance of the inverter or
solve technical problems, the version is subject to change without prior notice.
BR-13 Alarm information
This parameter captures the history of the 10 most recent alarms. Check the alarm information by
using the UP / DOWN buttons.
BR-14 Setting 1 or 3 phase of the motor
Check the ‘Phase’ on the motor nameplate and set phase as follows;
1: 1 phase
3: 3 phase
Caution:
Applies only to VARIOspeed MICRO D
.
Setting BR-14 incorrectly may result in permanent motor or
VFD damage
BR-15 Sleep stop delay time
When the drive slows to the minimum output frequency, it delays this amount of time before going to
“sleep”.
BR-16 Low pressure re-start time
After the low pressure alarm, the drive waits this amount of time, then restarts operation. The low
pressure icon starts blinking after the low pressure alarm faults 3 times.
BR-17 Motor FLA
This parameter is to be set to the maximum amperage allowed for the pump motor. If service factor
is needed, this must also be included. The VFD will fault and display drive error if this value is
exceeded for a long period of time.
Caution:
Setting BR-14 & BR-17 incorrectly may result in permanent motor or VFD damage.
