Power Controller - Siemens SIRIUS 3RF29.0-0KA-0KH0 Serie Instructivo

SIRIUS

Power controller

Operating Instructions
Read and understand these instructions before installing,
operating, or maintaining the equipment.
DANGER
!
Hazardous voltage.
Will cause death or serious injury.
Disconnect power before working on equipment.
CAUTION
Reliable functioning of the equipment is only ensured with
certified components.
Assembly / disassembly
Carry out assembly / disassembly in the order shown in Fig. I. Observe
the position of the electrical contacts (assembly step 1)

Commissioning
1. Connect the conductors as shown in the examples in Fig. IIa and
Fig. IIb.
2. The following setpoint options (setpoint value in % of the stored refe-
rence power rating of the loads) are available for the power control:
• If the setting switch "P" is in the 0 % position (left stop), enter the
setpoint value of 0 to 10 V (0 to 100 %) via an external analog
signal (terminal "10 V +" and "IN / 0 –"), refer to Fig. IIb.
• If the setting switch "P" is in the > 0 % position, enter the setpoint
value via the setting switch "P". It is switched on via the "IN / 0 –"
input. The analog input "10 V +" is not switched.
3. The following operating mode options are available:
• Fig. IIa: solid shaft operation
with setting switch position "t
(Ramp time = 0 s).
• Fig. IIb: phase angle
with setting switch position "t
max. 10 s for the inrush current limitation. The ramp time is only
active during switch-on and refers to 100 % of the setpoint value.
NOTICE
Modified settings will not take effect until the next switch-on. In
phase angle control operating mode, a reactor is required to
comply with limit values of the wire-bound interference voltage
(refer to Fig. IIb).
4. When the voltage is connected at A1 / A2 (24 V AC / DC) the fre-
quency of the voltage (load voltage) is determined. The load voltage
must be applied first.

Operation
The power controller can be switched on using the following options:
• Fig. IIIa: Via the debounced control input "IN / 0 –" with the setting
switch "P" in the > 0 position (also refer to Fig. IIa).
• Fig. IIIb: Via the analog input "10 V +" with the setting switch "P" in 0
position (also refer to Fig. IIb).
The "INPUT" LED will light up if one of the two ON signals are output.
The "ON" LED will light up when there is current flow.
Fault monitoring
The LEDs display the following faults:
• LOAD:
Load fault occurs if there is a failure of the connected load (I <1A longer
than 2s).
• THYRISTOR:
Thyristor fault occurs if no current flow is detected without an ON
signal being available.
• SUPPLY:
Supply fault occurs if there is an ON signal and no current flow is
detected, or if the supply voltage is too low or not available (see
device).
The faults displayed by the LEDs are signaled as a group signal via a
NC contact (terminals 11, 12).
Overload and short-circuit protection
The operator is responsible for providing sufficient overload and short-
circuit protection for the respective applications.
