Fault 1/1
Example of a fault display
The fault number and the respective text are shown in the 3rd line. Up to 8 fault
messages can be stored but only the first fault to occur is shown on the display. Several
subsequent faults are shown in the 4th line, e.g. with 1/3 (first of three). Information on all
faults can be obtained from the fault memory. With "Raise"/"Lower", the associated
operating hours are shown when a fault is waiting to be remedied.
After the cause of a fault has been removed, the fault is acknowledged with "Reset"
inside the operating display (the "Reset" key must be appropriately parameterized. See
section "Issuing commands via the OP1S"). By pressing "P" and "Lower" at the same
time, it is possible to skip back directly to the operating display from the parameter level.
When there is an alarm, the red LED flashes. A warning appears in the 4th line of the
operating display.

Example of an alarm display
The alarm number and the respective text is shown in the 4th line. There can be several
alarms at the same time but only the first alarm to occur is shown on the display. Several
alarms are shown in the 4th line before the alarm number with an "+“ instead of "-“.
Information on all alarms can be obtained with the alarm parameters.
An alarm cannot be acknowledged. As soon as the cause no longer exists, the
alarm/display disappears automatically.
