7.3.1 Explanation to status module
AccessMode
Status bit indicating whether the booster system is controlled from
the bus or from some other control source.
The booster system is controlled from a local source,
0: display or Grundfos GO Remote, or from an external
digital input.
1: The booster system is controlled from the bus, remotely.
To allow the booster system to be controlled from PROFIBUS/
PROFINET, the RemoteAccessReq control bit in the
ControlModule must be set to "1". However, certain commands
from other control sources, for example Stop or Max. from a local
source or external Stop from a digital input, have a higher priority
and sets the AccessMode to "0", indicating that the actual control
source is not PROFIBUS/PROFINET.
OnOff
Status bit indicating whether the booster system is started or
stopped.
0: The booster system is stopped (off).
1: The booster system is started (on).
The booster system can be started and stopped from the bus by
using the OnOff control bit in ControlModule.
"Started" does not necessarily indicate that the booster system is
pumping as it might be in a "low-flow stop" condition.
Fault
Status bit indicating that the booster system has been stopped
due to an alarm.
0: No alarm.
Alarm.
1: Booster system stopped, red booster LED on, FaultCode
(module 4) shows the alarm code.
Warning
Status bit indicating that the booster system has a warning.
0: No warning.
Warning.
1:
WarningCode (module 3) shows the warning code.
AtMaxSpeed
Status bit indicating that the booster system is running at
maximum performance.
The booster system is not running at maximum
0:
performance.
1: The booster system is running at maximum performance.
AtMinSpeed
Status bit indicating that the booster system is running at
minimum performance.
The booster system is not running at minimum
0:
performance.
1: The booster system is running at minimum performance.
CopyToLocal
Status bit indicating that the booster will copy remote settings to
local settings when it is switched from Access mode Remote to
Access mode Local. The involved settings are the control mode,
Operating mode and setpoint. This bit is not supported by Multi-E
model G and earlier models.
0: Copy of remote settings to local settings is not active.
1: Copy of remote settings to local settings is active.
ResetFaultAck
Acknowledge bit belonging to the ResetFault control bit. It will be
set when the control bit is set and the command has been
executed. It will be cleared when the control bit is cleared.
SetPointInfluence
Status bit indicating if the setpoint is influenced, for example by
analog input. If influenced, the ActualSetpoint (module 29) will
differ from the UserSetpoint (module 37).
0: No setpoint influence.
1: The setpoint is influenced.
Rotation
Status bit indicating that the booster system is pumping.
0: No rotation (not pumping).
1: Rotation (pumping).
ProcessFeedback
In closed-loop control, this is the value of the controlled process
variable (feedback/primary sensor). The process variable can
always be compared directly with the ActualSetpoint variable. If
no setpoint influence is active, it can also be compared with the
setpoint variable in the ControlModule.
In open-loop control, setpoint is mapped to ProcessFeedback.
The value of the feedback sensor can be read in the
corresponding measurement module.
