WARNING
HAZARDOUS VOLTAGE.
Can cause electrical shock
and burns.
Disconnect power before proceeding
with any work on this equipment.
Reliable functioning of the equipment is only ensured with certi-
fied 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 reference 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 sig-
nal (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.
Note:
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. After applying voltage to A1/A2 (24 V AC/DC or 110 V AC),
and before the first teaching procedure, the thyristor fault
(THYRISTOR) and supply fault (SUPPLY) LEDs will flash alter-
natingly every 0.5 s, since no reference power rating (100 %)
has yet been stored (taught) in the device, or if an impermis-
sible current or voltage value (too high or too low) has been
measured (see device) during the teaching procedure. The
group signal output is not activated.
5. Carry out the first storage of the reference power rating
(1st teaching procedure) by pressing the "Test/Teach" key for
more than 3 s under normal operating conditions (voltage and
current must not exceed the specified limit values). The end
of the teaching routine is signaled by the LOAD, THYRISTOR
and SUPPLY LEDs lighting up simultaneously for approx. 1 s
(Fig. III).
The teaching procedure can be repeated as frequently as
desired.
Note:
During the teaching procedure, the set ramp time "t
10 s) is fully run through. Interruptions during this period are
not possible.
Operation
The power controller can be switched on using the following
options:
• Fig. IVa: By pressing the "Test/Teach" key for less than 1 s for test
purposes.
• Fig. IVb: Via the debounced control input "IN / 0–" with the setting
switch "P" in the >0 position (also refer to Fig. IIa).
• Fig. IVc: 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 three 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 failure occurs if no current flow is detected although supply
voltage is applied and ON signal is available.
• 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.
