The operating modes are selected via the
the identity code, some operating modes may not be present):
'Analog' operating mode The stroke rate is controlled using an analog cur‐
rent signal via the "External control" terminal Processing of the current
signal can be preselected via the control unit.
'Manual' operating mode The stroke rate is set manually via the control
unit.
'Contact' operating mode: This operating mode provides the option of
making fine adjustments using small scaling or transfer factors. The
metering can be triggered either by a pulse received via the "External con‐
trol" terminal or through a contact or a semiconductor switching element. A
metering quantity (batch) or a number of strokes (scaling or transfer factor
0.01 to 100.00) can be pre-selected via the control unit using the
setting.
'Batch' operating mode: This operating mode provides the option of
working with large transfer factors (up to 99,999). The metering can be
triggered either by pressing the
"External control" terminal or through a contact or a semiconductor
switching element. It is possible to pre-select a metering quantity (batch)
or a number of strokes via the control unit.
'BUS' operating mode (Identity code, control variant: CANopen or PRO‐
FIBUS ® DP interface). This operating mode provides the option of control‐
ling the pump via BUS (see "Supplementary instructions for ProMinent
delta and Sigma with PROFIBUS
The following function can be ordered via the identity code:
Overload switch-off: As the power consumption is monitored, the pump
may switch off electronically if a defined tolerance range is exceeded. The
overload switch-off is to protect the pump, not the system.
The following functions can be selected using the
"Calibrate" function: The pump can also be operated in the calibrated state
in all operating modes. In this case, the corresponding continuous displays
can then indicate the metering volume or the capacity directly. Calibration
is maintained throughout the stroke rate range. The calibration is also
maintained when the stroke length is altered by up to ±10 % scale divi‐
sions.
"Auxiliary frequency" function: Enables a freely selectable and program‐
mable stroke rate to be switched on in the
controlled via the "external control" terminal. This auxiliary frequency has
priority over the operating mode stroke rate settings.
