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 status inputs are permanently assigned to the relays in the PUMP function. Relay 1
is monitored by digital input 1, relay 2 by digital input 2 etc.

Description
Output value if a sensor or device error occurs.
• Hold = last valid value
• Const = freely selectable value
• Min = output value is 3.5 mA for 4-20 mA, and 0 V or 0 mA otherwise
• Max = output value is 22.0 mA for 0/4-20 mA, and 1.1 V or 11 V otherwise
The freely selectable value for "Fail mode = Const" can be set here.
Current output: 0...22 mA
Voltage output: 0...11 V
Outputs the selected current at the output regardless of the input value.
Is automatically set to OFF when exited.
Outputs the selected voltage at the output, regardless of the input value.
Is automatically set to OFF when exited.
Description
Function of the selected digital input.
• OFF
• Pump = pump monitoring (see Pump monitoring function)
• Res. Tot. = reset the totalizer*
• Start/Stop = start or stop the totalizer*
• Min/Max = reset the min/max memory values
!
Note!
Parameters marked * are only available with the pulse output option.
Selects the side for evaluation.
• Low = descending side
• High = increasing side
Defines the time within which pump feedback at the digital input is to be expec-
ted. 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.
