9.13 Creating a master/slave application
You can connect several secondary pumps and control the
secondary pumps (slaves) via the first pump (master).
9.13.1 Master
All operating modes are available for the master pump:
• Manual
• Contact
• Batch dosing with manual/contact start
• Timer mode with manual/contact start
• Current control.
Select the output signal of the master pump in the service
level (relay 1) (output socket 3):
• Stroke signal (emits one output signal per stroke) must be
used for manual or current control of the master pump, or
• pulse input (emits one output signal per contact input signal)
must be used for contact control of the master pump.
Alternatively select the current output (output socket 2) for
current control of the slave pump.
9.13.2 Slave
The following operating modes are available for slave pumps in
contact or current control (input socket 4):
• Contact
• Batch dosing with contact start
• Timer mode with contact start
• Current control.
Note
Please note that the current output can differ from
the current input, e.g. when the pump is stopped, and
please observe the modified current output values
with weighted current control.
Note
The settings for the operating modes of the slave
pumps are implemented independently of settings for
the master pump.
Caution
Unused pulse inputs from the master pump are
forwarded to the slave pumps when output signal =
pulse input is set. They are processed on the slave
pumps according to the slave pump settings!
