6.3.4 Digital input - DIGITAL INP./M5
The settings for the digital status inputs, e.g. for monitoring pumps, starting/stopping the
counter or resetting the min/max-value memory are grouped in this section.
!
Note!
– The digital inputs 1 to 4 are permanently assigned to relays 1 to 4 in the PUMP function.
Relay 1 is monitored by digital input 1, relay 2 by digital input 2 etc.
– When the "Batch" function is used, digital input 1 is permanently assigned to a preset value
count function. Configuration for this digital input is then not possible.

feedback at the digital input is to be expected. If there
is no feedback within the defined time, an error
message is generated and a second pump is activated if
more than one pump is available.

monitoring behavior of the digital input!
Sampl. time = 0 means fault monitoring
Sampl. time <> 0 means operation monitoring
