Operating Manual

Error during active configuration

Events during active configuration are used to monitor the device during opera-

tion. The reaction to one of these events can be set in four levels - inactive, mes-

sage, warning or fault.

1. When an event is parameterized as a message, it is shown flashing at the bot-

tom of the display. An application is not affected by a message (i.e., the top

part of the display does not change). A message is not acknowledged. It is

queued until the cause disappears.

2. A warning is shown in the top part of the display with the appropriate logo. The

bottom line indicates the flashing event. The upper right corner shows the re-

maining time after which the warning becomes a fault. If the cause disappears

within this parameterized time, the warning is reset. An application is not af-

fected by a warning.

3. When an event with the level "fault" occurs, the device immediately changes

to the device state "fault reaction." The event appears flashing in the bottom

line of the display. A fault must be acknowledged.

The device provides notes on the cause of some of the events. These events are

marked with a number and appear alternately to the event indicators on the dis-

play. Causes which are not documented with a number in the event description

are only an indication of possible faults. They do not appear on the display.

For additional diagnosis, the occurrence of an event of this group is documented

by incrementing a counter. The fault counters are stored in the parameter group

Z.. An acknowledgment can be programmed on the operator panel or via binary

input for some of these events. These events do not affect communication and

device control. The events can be identified by their consecutive numbering.

Sequence faults recognized by the CPU

The 5

generation of STÖBER inverters includes a digital computer with micro-

processor, memory and I/O modules. When an error occurs which affects this ar-

ea, the device reacts with an indication on the display. At the same time, the

inverter assumes a defined state (power section is turned off). The device must

be turned off and on again before it can return to its normal functionality.

At the same time, device control (menu function) and communication with the in-

verter are not possible. Events of this type are marked on the display with the

character "#".

Inactive configuration…

There are two cases when a configuration is inactive:

1. A fault occurs during device start.

2. The configuration was stopped by POSITool.

Events which will lead to an inactive configuration are marked on the display with

an asterisk (*).
