Malfunction - Bender ISOMETER isoGEN423 Manual

Error code
Reversed polarity connection error
Terminals 'L1/+' and 'L2/–' are connected to the DC system to be monitored with reversed polarity.
E.03
Detection from U
Measurement error
Due to system interferences or a device error, the insulation measured value is no longer updated.
Prewarning and alarm are set for the insulation measured value at the same time.
E.05
Calibration invalid after software update
'E.05' appears together with 'E.08': The software is not compatible to the calibration of the device.
Action: Install the previous software version or have the device calibrated at the factory.
Permissible system leakage capacitance C
(only in 'dc' setting)
E.07
The device is not suitable for the present network leakage capacitance C
Action: Uninstall the device.
Calibration error
E.08
Action: Check connection, eliminate error. If the error is still present, there is a device error.
Internal device errors 'E.xx' can be caused by external disturbances or internal hardware errors. If the error
message occurs again after the device has been restarted or after a reset to the factory settings (menu item
'FAC'), the device must be repaired. After the fault has been eliminated, the alarm relays switch back either
automatically or when the reset button is pressed. The self test can take a few minutes.
2.3.6.1 Automatic self test
In the factory setting a self test is carried out when the supply voltage U
This cycle can be adjusted: off, 1 h, 24 h (see chapter 4.6).
The self test can be suppressed for the device start so that the device can enter the measurement mode more
quickly. To this end, set the parameter 'S.Ct = off' in the menu 'SEt'.
2.3.6.2 Manual self test
The manual self test is started by pressing the external test/reset button or the test button 'T' on the device for
˃ 1.5 s. Holding the test button 'T' also shows all display elements.

Malfunction

The device checks some of its functions continuously during operation. If a fault is detected, the device
error ('err') will be signalled, 'E.xx' appears on the display as an identifier for error type xx, and the LEDs
'ON'/'AL1'/'AL2' will flash.
Please contact Bender Service, if the error occurs again after the device has been restarted or the factory
settings have been restored.
