Signal for overflow level.
–
Dry Run
Signal for dry-running protection.
–
Reset
External signal to reset error messages.
–
System Off
External signal to switch off the system.
–
Trigger Start Level
Start drainage pumping sequence. Pump chamber is drained to the switch-off
level.
–
Alternative Start Level
Activate alternative switch-on level.
NOTICE! The assignment must match the hardware assignment at the I/O module!
6.5.7.3
Analog Inputs
Assigning the available functions to the relevant inputs. The name of the input termin-
als matches the name on the I/O module. Available functions can be freely assigned for
the following inputs:
ƒ
Input 1 Function
ƒ
Input 2 Function
ƒ
Input 3 Function
Settings
ƒ
Input 1 Function ... Input 3 Function
Factory setting: Not In Use
Input:
NOTICE! In LPI system mode, the functions on the I/O module are the same as on
the frequency converter. The following description addresses the LSI system
mode.
–
Level
Setpoint specification for the control modes in LSI system mode.
NOTICE! Requirements for the LSI system mode! Assign this function to an in-
put.
–
Pressure
Recording the current system pressure to record data.
NOTICE! Can be used as control value for the PID controller!
–
Flow
Recording the current flow rate to record data.
NOTICE! Can be used as control value for the PID and HE controller!
–
External Control Value
Setpoint specification from a higher-level control system to the control of the
pumping station as an analogue signal.
NOTICE! In LSI system mode, the pump-
ing station operates autonomously from a higher-level control system. If the
setpoint specification must be made by a higher-level control system, please
contact customer service!
ƒ
Input 1 Type ... Input 3 Type
Selected measurement range is transferred to the I/O module.
NOTICE! Set the sig-
nal type (current or voltage) in the hardware. Observe the manufacturer's in-
structions!
Factory setting: 4 ... 20 mA
Input:
–
0 ... 20 mA
–
4 ... 20 mA
–
0 ... 10 V
ƒ
Input 1 Scale Max ... Input 3 Scale Max
Factory setting: 1
Input: Maximum value as real numerical value with unit. The units for the control val-
ues are:
- Level = m
- Pressure = bar
- Flow = l/s
Separator for decimal places: Point
