Releasing The Function(S) To Be Tested - ABB REL670 Installation And Commissioning Manual

2.6
Preparing for test
4. Compare the frequency reading with the set frequency and the direc-
tion of the power with the injected power.
The frequency and active power are located in the local HMI under:
Measurements\Monitoring\ServiceValues\SVR
5. Inject an unsymmetrical three-phase current and voltage at rated val-
ue in two phases.
6. Compare the injected value with the measured value.
The current phasor menu is located in the local-HMI under:
Measurements\Monitoring\CurrentPhasors\CPnn
The voltage phasor menu is located in the local HMI under:
Measurements\Monitoring\VoltagePhasors\VPnn

Releasing the function(s) to be tested

The user can release/unblock the function(s) to be tested. This is done to ensure that only the
function(s) under test are in operation and that other functions are prevented from operating. The
user can release the tested function(s) by setting the corresponding blocked parameter under
Function test modes to NO in the local HMI. When testing a function in this blocking feature,
remember that not only the actual function must be activated, but the whole sequence of inter-
connected functions (from measuring inputs to binary output contacts), including logic and so
on. Before starting a new test mode session the user should scroll through every function to en-
sure that only the function to be tested (and the interconnected ones) are set to NO. A function
is also blocked if the BLOCK input signal on the corresponding function block is active, which
depends on the configuration. The user should therefore ensure that the logical status of the
BLOCK input signal is equal to 0 for the function to be tested. The user could also individually
block event blocks to ensure that no events are reported to a remote station during the test.
Note!
The function is blocked if the corresponding setting under the Function test modes menu remains
on and the TEST-INPUT signal remains active. All functions that were blocked or released from
a previous test mode session are reset when a new test mode session is started.
Procedure
1. Browse to the 'Function test modes' menu.
The Function test modes menu is located in the local HMI under:
