Installation and operating instructions Wilo-Control CC-Booster 13
Sensors
Connect the sensor correctly to the terminals
according to the circuit diagram in the installation
and operating instructions.
Use a shielded cable, place the shield on one side
in the switchbox.
CAUTION! Risk of damage to the product!
Do not connect any external voltage to the
terminals!
NOTICE:
Observe the correct polarity of the pressure sen
-
sor! Do not attach an active pressure sensor.
Analogue IN, setpoint remote adjustment/speed
remote adjustment
Remote adjustment of the setpoint or, in the
"constant speed" operating mode of the speed, is
possible using an analogue signal (0/4...20 mA or
0/2...10 V) by means of the corresponding termi
-
nals in accordance with the circuit diagram. Use a
shielded cable, place the shield on one side in the
switchbox.
Setpoint changeover
Using the corresponding terminals in accordance
with the circuit diagram, it is possible to force a
switchover from setpoint 1 to setpoint 2 or 3 using
a potential-free contact (normally open contact).
x: Contact closed; o: Contact open
CAUTION! Risk of damage to the product!
Do not connect any external voltage to the
terminals!
External activation/deactivation
Using the corresponding terminals in accordance
with the circuit diagram, it is possible to connect a
remote activation/deactivation by means of a
potential-free contact (normally closed contact)
after removing the converter bridge (pre-
assembled as a factory setting).
CAUTION! Risk of damage to the product!
Do not connect any external voltage to the
terminals!
Protection against low water level
Using the corresponding terminals (in accordance
with the circuit diagram), it is possible to connect
a function for protection against low water level
by means of a potential-free contact (normally
closed contact) after removing the converter
bridge (pre-assembled as a factory setting).
CAUTION! Risk of damage to the product!
Do not connect any external voltage to the
terminals!
Collective run/collective fault signals (SBM/SSM)
Potential-free contacts (changeover contacts) for
external signals are available via the correspond
-
ing terminals in accordance with the circuit
diagram.
Potential-free contacts, contact load:
– Minimum: 12 V, 10 mA
– Maximum: 250 V, 1 A
DANGER! Risk of fatal electrical shock!
There can be a potentially fatal voltage on these
terminals, even when the main switch is
switched off.
Display of actual pressure value
A 0 to 10 V signal for an external measurement/
display option of the current control variable
actual value is available via the corresponding ter
-
minals in accordance with the circuit diagram.
0 to 10 V corresponds to the pressure sensor
signal 0 to pressure sensor limit value e.g.
CAUTION! Risk of damage to the product!
Do not connect any external voltage to the
terminals!
Actual frequency display
For switchgear with frequency converter (CC-FC
and CCe versions), a 0 to 10 V signal for an exter
-
nal measuring/display option of the current actual
frequency of the base-load pump is available via
the corresponding terminals as per the circuit
diagram.
0 ... 10 V corresponds to the frequency range
0...f
max.
CAUTION! Risk of damage to the product!
Do not connect any external voltage to the
terminals!
