(When the temperature is 0: or less, "–" and
temperature are displayed by turns.)
-39 – 88
(When the temperature is 0: or less, "–" and

-40 – 200
(When the temperature is 0: or less, "–" and
temperature are displayed by turns.)
(When the thermistor detects 100: or more,
hundreds digit, tens digit and ones digit are displayed
by turns.)
0 – 255
(When the temperature is 100°C or more, hundreds
digit, tens digit and ones digit are displayed by
turns.)
0 – FFFE (in hexadecimal notation)
(When more than FF in hex (255 in decimal), the
number is displayed in order of 16

Description
Normal
Overvoltage error
Undervoltage error
Input current sensor error
L -phase open error

Abnormal power synchronous signal
PFC error (ZRP35-71V)
(Overvoltage / Undervoltage / Overcurrent)
PFC/ IGBT error (ZRP60-140V)
Undervoltage
* Display examples for multiple errors:
Overvoltage (01) + Undervoltage (02) = 03
Undervoltage (02) + Power-sync signal error (08) = 0A
L phase open error (04) + PFC error (10) = 14
