Cause
DC/DC converter unit has
received an emergency stop
(mode selection off2)
command.
DC/DC converter unit has
received an emergency stop
(mode selection off1 or off3)
command.
No enable start signal
received.
No run enable signal is
received.
195.04 Control board supply
set to External 24V but no
voltage is connected to the
XPOW connector of the control
unit.
DC/DC converter module
temperature is excessive due
to eg, module overload or fan
failure. (Control program
generates first a warning, then
a fault.)
High control board tempera-
ture.
An analog signal is outside the
limits specified for the analog
input.
DDCS (fiber optic)
communication between the
DC/DC converter unit and
external controller is lost.
Internal SW error
What to do
Check that it is safe to continue
operation.
Return emergency stop push button to
normal position.
Restart the DC/DC converter unit.
If the emergency stop was unintentional,
check the source of the stop signal (for
example, 121.05 Emergency stop
source, or control word received from an
external control system).
Check the setting of (and the source
selected by) parameter
start signal.
Check setting of parameter
enable 1. Switch signal on or check
wiring of selected source.
is Check the external 24 V DC power
supply to the control unit, or change the
setting of parameter
board supply.
Check module cooling air flow and fan
operation.
Check ambient temperature. If it exceeds
40 °C (104 °F), ensure that load current
does not exceed derated load capacity.
See appropriate Hardware manual.
Check inside of cabinet and heatsink of
DC/DC converter module for dust pick-
up. Clean whenever necessary.
Check the wiring and status of thermal
switches inside the cabinet.
Check proper cooling of the cabinet.
Check the event log for an auxiliary code
(format XYY). "X" specifies the location of
the input (0: AI on control unit; 1: I/O
extension module 1, etc.), "YY" specifies
the input and limit (01: AI1 under
minimum, 02: AI1 over maximum,
03: AI2 under minimum, 04: AI2 over
maximum).
Check signal level at the analog input.
Check the wiring connected to the input.
Check the minimum and maximum limits
of the input in parameter group
Standard AI.
Check status of controller. See the user
documentation of the controller.
Check settings of parameter group
DDCS communication.
Check cable connections. If necessary,
replace cables.
Contact your local ABB representative.
Quote the auxiliary code (check the event
details in the event log).
