Carrier 50XJ064-104 Keys and Functions for 50XJ VFD, VFD Non-Trip Messages for 50XJ Unit

STATUS MONITOR MODE — In Status Monitor mode, it is possible to monitor the VFD status (frequency command, output voltage, current, terminal information, etc.). Status monitor mode is entered by pressing the Setup/Program/Monitor key, then selecting MON at the mode selection menu and pressing the Read/Write key. Table 11 details the procedure for entering status monitor mode (from standard monitor mode) and viewing all the monitored status variables. 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.

MANUAL MODE — To override the automatic unit controls and manually operate the fan from the VFD display, press keys for “MANUAL” run mode, “LOCAL” speed control, and press the Up or Down arrow keys to increase or decrease output frequency.
