Operating message and fault indication
The operating message is indicated via the green LED on the left alongside the display and can be tapped
via the potential-free relay contact (connection C5 / S5).
A fault indication is displayed via the red LED on the left alongside the display and can be tapped via the
potential-free relay contact (connection C5 / Ö5). Here too an alarm signal also sounds.
An existing fault must be cleared and acknowledged with the key
!
Hall effect sensor fault: If the Hall effect sensor has a fault during backwashing (e.g. due to a disconnected
coupling or damaged connecting cable) or after replacement of a defective control unit or a defective linear
drive a “Hall fault” is output to the display.
An interrupted backwashing process is not automatically continued after fault clearance
and acknowledgement, rather if necessary it must be repeated by triggering manual
backwashing (see Chap. 5.2)!
During operation the day of the week is displayed together with the current
time.
Below this the active or inactive inputs and outputs are displayed (here for
example operating relay active, i.e. O:1).
As during backwashing the sequential pulses of the Hall effect sensor for
movement of the linear drive are displayed, the inputs and outputs are not
displayed during this period.
