Table 7 | Error codes
(Blank)
No display is lightning.
The input current is lower than 2.0 mA or input signal connections
is inverted.
‘Lo’ The input current is lower than 3.8 mA.
‘h.oVr’
‘Hardware overrange’.
Input signal is above the maximum readable signal (+22 mA).
‘Err.3’
‘Password error’.
If ‘password’ function is active, the password code entered is not
correct.
In case of error, the error code is shown flashing on display. The error
codes are not visible while on ‘ configuration mode ’ or in ‘ fast access ’
menu.
The error code remains active on display until the problem that caused
the error is solved. In case of multiple error codes, solve the first problem
to see the next active error code.
