PFR-X **R / PFR-M **T

Monitoring
The monitoring functions ensure long and reliable operation of the
capacitor equipment: PFR-M only:
- zero-voltage tripping to avoid contactor fibrillation - cosφ alarm
- overvoltage protection - frequency alarm
- over-temperature protection - overload Q
- harmonic monitoring of voltage and current - overload P
- detection of defect capacitors (with adjustable threshold value) - P export
- alarm at under-compensation
- maintenance reminder
- fan control output (can also be used as additional capacitor output)
- overcurrent
- no current

Malfunctions and status signals of the equipment are indicated in the LC-Display. Malfunctions can also be transmitted through
+
the isolated alarm relay (PFR-X : N-O contact, PFR-M: S-P-D-T contact) or to the digital output (PFR-M only).
Special Features of PFR-M
- Transistor outputs for the operation with thyristor switches (dynamic compensation)

- Optionally available with relay outputs or as hybrid version (PFR-M 12RT) with 6 relay outputs for static loads and 6 transistor
outputs for dynamic loads
- fast algorithm for dynamic thyristor operation (switching time ~20ms) POWER FACTOR CONTROLLERS
- Available with optional modbus communication
- Optional 3 Phase current measurement

Special Features of PFR-X +
- Guided setup through commissioning process of the controller
- Fan relay can be used as 7th or 13th step
- Step balancing (equal distribution of switching cycles) available based either on operation hours per step or on number of
switching cycles.
- optional modbus communication
- Storage of the last 10 alarms
- Suppression of “I lo” alarms possible via digital input.

Modbus Option
The MODBUS extension offers the possibility to read values from the device and modify various settings.
The MODBUS-protocol doesn‘t restrict the user to one single physical transmission system. With the bus-capable RS485 inter-
face, it is possible to connect more than one controller to a single pair of wires and access the units by use of an ID number.
Many commercial devices and PLCs are able to use the MODBUS protocol either as bus master or slave. Various SCADA solutions
are also available from a variety of vendors. For this reason, the integration in a new or existing bus-system is only a minor issue.
