10. Diagnosis/Troubleshooting
ISEO drive units meet a high safety standard and comply
with all technical regulations and requirements. Internal as
well as external safety circuits managed by the drive unit will
be periodically monitored.
During the operation of the devices, situations may arise that
lead to an error message.
The drive unit tries to determine the cause and react
accordingly. The reaction takes place depending on the
severity of the cause and ranges from an information to the
shutdown of the automatic functions of the drive unit.
In this case, the drive unit switches into the emergency
mode and acts as a door closer.
The door can be manually passed through.
Information “In“ and error messages “E0“ ... “E9“ will be
output on the display of the user interface and the red LED
on the internal program switch.
The output to the LED is coded and can be taken from the
error table.
Error messages “E0“ ... “E9“ will be saved in the error
memory and can be read off the display of the interface.
A current error information will always occupy the error
message memory cell E0. In case of another error or its
acknowledgement, it will be moved to the error message
memory cell E1.
A maximum of 9 errors can be saved in the error memories
E1 – E9. The same error messages occuring successively will
not be saved again.
To call up the error messages E0 ... briefly press E9.
Information "In"
Information is provided for the easy servicing of the drive
unit and points to both faulty states and operating states
that suppress the automatic operation of the drive unit.
Example:
In 08 -> Emergency stop is pressed; the drive unit does
not perform automatic functions.
In 01 -> A blocking has been detected; the drive unit
keeps operating.
An information can become an error message in case of a
repeated occurance.
Error messages “E0“ ... “E9“
Error messages indicate a hardware defect. However,
installation errors and the manual operation during safety
tests can also cause error messages, and the system will
switch into the emergency mode. The following options are
available for the reset of error messages:
• Switching the program switch to off or resetting by
pressing the reset button of the user interface with the
casing open.
• Mains reset. Switching off the power switch. Restart
after 10 seconds.
The cause should be analyzed and eliminated before an error
message is acknowledged. The following table will provide
assistance.

Possible cause
Remedy
The door can be passed
only manually or the
door does not open
automatically after an
opening pulse.
Testing of the green LED.
If the green LED is not on, there is a
problem with the power supply.
The power switch must be switched on.
The power supply must be tested and restored, if
necessary.
If power is supplied but 24 V DC is not available, the
mains adaptor must be replaced.
Testing of the red LED.
If the LED flashes on the power switch,
the control unit found an error and the
emergency mode is activated.
The troubleshooting is described in the "Information
and error messages" list.
The program switch is in the Off or Exit
only position.
Put the program switch into the Automatic or
Permanent Open position.
There is a signal from the safety sensor
on the hinge side. This signal prevents
the opening.
The signals of the safety sensors will be displayed for
the diagnosis directly with the 2 decimal
points of the LED display on the user
interface.
In case of a detection, the respective decimal point will
light.
The wiring and function of the system must be tested.
If the LED at the top left flashes, the wall suppression
will be active. There is no error.
