12�3 Ripple Control Receiver

The Solar-Log™ PM+ series contains an additional 6-pin interface which allows up to two ripple control

receivers or telecontrol plants each with four signals to be connected.

Wiring

The relay contacts for the ripple control receiver are connected to the Solar-Log™ PM+ via the 6 pin PM+

interface on the top side of the Solar-Log

TM

.

The ripple control receivers used by grid operators utilize various numbers of relays. These relays are la-

beled differently and have different reduction levels and/or shift factors cos (Phi).

To ensure the highest degree of flexibility, the reduction levels specified by the grid operators, together

with their signals from the ripple control receiver, can be evaluated by the Solar-Log

TM

via a maximum of

four digital inputs for each.

In order that the Solar-Log™ PM+ can evaluate the signal from the ripple control receiver, it needs to be

wired to the control voltage (for active and reactive power) from the PM+ interface. The control contracts

normally operate as make contracts; that means the closed for the respective command.

The control voltage from Pin 1 is used for the active power command.

The control voltage from Pin 6 is used for the reactive power command.

The control voltage is connected to the common contact of each relay. The relay output (closed contact)

is then connected to a digital input of the PM+ interface.
