Technical Manual
• FIXCOIL, OP_FIXCOIL and CL_FIXCOIL: Status signal and corresponding
open and close command signals for controlling the circuit breaker or
disconnector of the fixed parallel coil. These signals are applied if a fixed parallel
coil is installed in the system.
• RESISTOR, OP_RESISTOR and CL_RESISTOR: Status signal and
corresponding open and close command signals for controlling the contactor,
circuit breaker or disconnector of the parallel resistor. These signals are applied
if a parallel resistor is installed in the system.
An example configuration of the connections is shown in
inputs are indicated with red lines and outputs with green lines. This example shows
a simple, one-controller setup without the parallel resistor of the coil.

Operation principle

The Operation setting is used to enable or disable the function. The corresponding
parameter values are "on" and "off".
The operation of PASANCR can be described with a module diagram. All the
modules in the diagram are explained in the next sections.
