9. Secondary system supervision displays a choice of functions, Current circuit
supervision and Fuse failure. Current circuit measurements include fail and alarm
signals, and fuse failure measurements consist of start data.
10. Control displays the Synchrocheck, and Apparatus control functions. The
Synchrocheck functions include a number of function related measurements such
as calculated differences. Apparatus control includes up to 19 functions each
with their own set of measurement data regarding interlocking, breaker and
isolator conditions.
11. Logic displays a choice of functions available to the operator. These are Trip
logic, Event counter, Logic gate, Logic memory and Logic timer set each with
their own set of measurements.
12. Monitoring displays a choice of functions available to the operator. Function
related measurements can be viewed by navigating to the screen for each
individual function. One of the submenus shows the status of the LEDs on the
HMI.
13. Communication displays submenus for Remote communication and Receiving
interlock information.
All measurement descriptions in this document reflect the maximum number of
hardware units possible in any application. In reality the hardware in the IED will be
chosen according to a particular application. For example, it is possible to equip a 1/1
x 19” case IED with 14 I/O modules. In reality fewer I/O modules may be installed.
In the measurements menu the operator will only see data from the hardware and
software installed.

IED test mode
Test/IED test mode
Displays one setting which is used to activate and deactivate functions so that tests
can be performed without endangering system stability.

Overview
Binary input values display the state of each individual input in the Binary input
modules (BIM). These are indicated with a 1 or 0 depending on whether a signal is
present or not. Binary input modules with enhanced pulse counting capabilities can
receive pulses used for power measurement. The number of pulses received is used
to measure power.
