Troubleshooting
Table 31:
Table of malfunctions
Malfunction
Possible cause
Addressing via DHCP
A save process was triggered on the bus
server not possible
coupler before the address 0x00 was set.
Wrong address set
UL LED flashes red
The electronics supply voltage is less
than the lower tolerance limit (18 V DC)
and greater than 10 V DC.
UL LED illuminated red
The electronics supply voltage is less
than 10 V DC.
UL LED is off
The electronics supply voltage is
significantly less than 10 V DC.
UA LED flashes red
The actuator voltage is less than the
lower tolerance limit (21.6 V DC) and
greater than UA-OFF.
UA LED illuminated red The actuator voltage is less than UA-OFF.
MOD LED flashes green No connection has been established with
a master.
MOD LED flashes red
Diagnostic message from module
present
MOD LED illuminated
There is no module connected to the bus
red
coupler.
There is no end plate present.
More than 32 electrical components
are connected on the valve side
(see section 12.5.3 "Impermissible
configurations" on page 116).
More than 10 modules are connected
in the I/O zone (see "12.6 Conversion of
the I/O zone" on page 118).
The module circuit boards are not
plugged together correctly.
A module circuit board is defective.
The bus coupler is defective.
The new module is not recognized.
NET LED illuminated
Severe network error present
red
IP address assigned twice
Remedy
Perform the following four steps:
1. Disconnect the bus coupler from the
voltage and set an address between
1 and 254 (0x01 and 0xFE).
2. Connect the bus coupler to the
voltage and wait 5 seconds, then
disconnect the voltage again.
3. Set the address switch to 0x00.
4. Re-connect the bus coupler to the
voltage.
Addressing via the DHCP server
should now work.
Disconnect the bus coupler from the
voltage UL and then set the correct
address (see 9.2 "Changing the address"
on page 95)
Check the power supply at plug X1S.
Configure the master so that it
establishes a connection.
Check modules.
Connect a module.
Connect an end plate.
Reduce the number of electrical
components on the valve side to 32.
Reduce the number of modules
in the I/O zone to ten.
Check the plug contacts of all modules
(I/O modules, bus coupler, valve drivers,
and end plates).
Exchange the defective module.
Exchange the bus coupler
