Connections of the signal inputs
and outputs

DANGER! Risk of fatal injury!
Contact voltage dangerous to human life
Work on the module may only be started once 5 minutes have
passed, due to the dangerous residual contact voltage (capacitors).
• Before working on the pump, disconnect the supply voltage and
wait for 5 minutes.
• Check whether all connections (including potential-free contacts)
are voltage-free.
CAUTION! Risk of damage!
Risk of damage due to inappropriate handling.
• Do not connect any external voltage. That could destroy the
module.
(Terminal 1, output): +10 V DC
Power supply for signal connection terminals
(Terminal 2, analogue input): 0...10 V/0...20 mA
As external setpoint signal
Conversion between voltage and current signals:
• 0...10 V
via switch position S3
• 0...20 mA
via switch position S3
The frequency and thus the speed or the set pressure follow the volt-
age or, if a current signal is chosen, the current (Fig. 10 + 11).
(Terminal 3, analogue input): 0...10 V/0...20 mA (1)
As external actual value signal (setting for differential pressure
sensor)
Conversion between voltage and current signals:
• 0...10 V
via switch position S4
• 0...20 mA
via switch position S4
(Terminal 4, output): +24 V (3)
DC voltage for an ext. consumer/sensor. The voltage is short-circuit
proof.
(Terminal 7/15, output): GND (2)
Earth connections for signal inputs (0...10 V/0...20 mA).
(Terminal 10, digital input): operating mode
Switching between pressure controlled operation (Δp-c) or manual
control mode (n-const):
• Δp-c Bridge to terminal 5
• n-const Bridge to terminal 5
(Terminal 18, digital input): Ext. off
Setting of the Ext. off function:
• Release Bridge to terminal 11 closed (factory setting)
• Block Bridge to terminal 11 open
If the contact is closed, the module is ready for operation.
If the contact is open, the pump is switched off.
NOTE
With a DIE...BV, the changes to terminals 10 and 18 are to be made on
the master only.
(Terminals 31-32-33, output): SBM (collective run signal);
potential-free changeover contact
During operation of the pump, the corresponding contacts as
• NC contact between terminals 31 + 32 are
• NO contact between terminals 31 + 33 are
(factory setting)
