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.
