50BV Variable Frequency Drive Control — The variable frequency drive is factory wired and programmed for proper operation with the unit controls; no installation or service adjustments are normally required.

The VFD default conditions at unit power up are: “0.0 Hz” in the LED display. When the fan is operating, the LED displays the output frequency in Hz.

OPERATING KEYPAD — The keypad allows users to en- able or disable the keypad, input commands from the keypad, and monitor drive operation. Fig. 7 shows the operating panel keypad layout and the locations of the keys and display LEDs.

The 4-character LED displays various values, depending upon what mode is running.

•In Standard Monitor mode: the LED displays the current output frequency.

•In Status Monitor mode: monitors the status conditions and frequency command value setting.

•In Setup mode: displays setup parameter titles and values.

•During a trip: displays the trip title.

The appropriate local/remote LED, which is inset into the speed control key, is lit when the unit is in local or remote mode.

KEY FUNCTIONS — Refer to Fig. 8 for the functions of each key on the keypad.

NON-TRIP MESSAGES — Non-trip messages are those that may be displayed but do not cause a trip and are not recorded in the fault history. Table 15 lists the non-trip messages with their explanations.

TRIP MESSAGES — Trip messages and their causes are shown in Table 16.

CLEARING A TRIP — A trip clear can be performed after the cause of the trip has been removed. To perform a trip clear, either switch off power to the inverter (keep VFD off until charge LED turns off) or use the following procedure:

Press STOP. The display will show: CLr. Press STOP again. The display will show: 0.0, indicating that the trip is cleared and the display will return to Standard Monitor mode.

If any key other than the STOP key is pressed at the trip clear command prompt, the trip clear command is aborted and the display returns to Standard Monitor mode (where the trip title will be displayed flashing). The trip clear command does not clear the recorded past faults.

STATUS MONITOR MODE — In Status Monitor mode, it is possible to monitor the inverter status (frequency command, output voltage, current, terminal information, etc.). Status monitor mode is entered by pressing the MON key until the monitor LED is lit. The present output frequency (which, just after power is applied, is 0.0) is displayed. (If the ST-CC terminals are not shorted, OFF will be displayed.)

If either or is pressed continuously, every 0.5 sec the next/previous item will be displayed. As optional points, RUN, STOP, displaying the frequency status, and switching to local/remote and manual/auto modes can be performed.
