The monitor items on the LED monitor can be switched by pressing the key. Monitor items Monitor page # (See Table 3.4.) Operation guide Figure 3.5 LCD Monitor Sample Detailed for the LED Monitor Item (Note 1) These PID related items appear only under PID control specified by function code J01 (= 1, 2 or 3). When a PID command or PID output is displayed, the dot at the lowest digit on the LED monitor blinks; when a PID feedback amount is displayed, it is lit. (Note 2) The analog input monitor appears only when the analog input monitor is enabled by any of function codes E61 to E63 (Select terminal function). (Note 3) Under V/f control, a zero (0) is displayed. 3-6
3.3.3 Monitoring light alarms The <strong>EQ7</strong> identifies abnormal states in two categories--Alarm and Light alarm. If the former occurs, the inverter immediately trips; if the latter occurs, the appears on the LED monitor and the "L-ALARM" appears blinking in the operation guide area on the LCD monitor, but the inverter continues to run without tripping. Which abnormal states are categorized as a light alarm ("Light alarm" object) should be defined with function codes H81 and H82 beforehand. Assigning the LALM signal to any one of the digital output terminals with any of function codes E20 to E24 and E27 (data = 98) enables the inverter to output the LALM signal on that terminal upon occurrence of a light alarm. Means that a light alarm has occurred. Running status Rotational direction Indicator indexes Operation guides Means that a light alarm has occurred. Figure 3.6 Display of Light Alarm For details of the light alarms, refer to Chapter 10 "TROUBLESHOOTING." • How to check a light alarm If a light alarm occurs, the appears on the LED monitor. To check the current light alarm, enter Programming mode by pressing the key and select LALM1 on Menu #5 "Maintenance Information." It is also possible to check the last three light alarms by selecting LALM2 (last) to LALM4 (3rd last). For details of the menu transition of the maintenance information, refer to Section 3.4.6 "Reading maintenance information." • How to remove the current light alarm After checking the current light alarm, to switch the LED monitor from the display (e.g., output frequency), press the key in Running mode. indication back to the running status If the light alarm has been removed, the "L-ALARM" disappears and the LALM output signal turns OFF. If not (e.g. DC fan lock), the on the LED monitor disappears so that normal monitoring becomes available, but the "L-ALARM" remains displayed on the LCD monitor (as shown below) and the LALM output signal remains ON. The has disappeared and the normal LED monitor is displayed. Running status Rotational direction Indicator indexes Operation guides The operation guides remain displayed. 3-7
