 Hexadecimal expression
A 4-bit binary number can be expressed in hexadecimal format (1 hexadecimal digit). The table below shows the
correspondence between the two notations. The hexadecimals are shown as they appear on the LED monitor.

When the H26 data is set to "1" (PTC (The inverter immediately trips with 0h4 displayed)), if the PTC
thermistor is activated, the inverter stops without displaying
l-al , blinking the KEYPAD CONTROL LED,
or outputting
L-ALM signal, regardless of the assignment of
b
it 11 (PTC thermistor activated) by H82 (Light
Alarm Selection 2).
 Light alarm--L-ALM (E20 to E24 and E27, data = 98)
This output signal comes ON when a light alarm occurs.
