Setting the Real Time Clock
The time and date must be set when a new HOA keypad is plugged in and the drive is powered up. The HOA keypad will
display the time and date setup screen for 30 seconds. If a button is not pressed during this time, the display will clear and a
“Clock Not Set” alarm will flash. Pressing the F2 (Data) key will display the setting screen again.
n
Feedback Loss Wire Break Alarm
If there is no sensor wired to the drive, a “Feedback Loss – Wire Break” alarm will flash on the display. Providing the proper
feedback device signal will clear the Feedback Loss alarm.
The drive requires a feedback device (e.g., pressure transducer, flow meter, etc.) to perform automatic system regulation. Any
analog 0~10 V or 4-20 mA feedback device can be used in combination with the drive.
Note:
The factory default setting for the drive is 4~20 mA feedback device connected to analog input A2.
