CHAPTER 6:  COMMISSIONING 6.3 GENERAL CONSIDERATIONS, POWER SUPPLY NETWORK
GEK-113000-AF F650 DIGITAL BAY CONTROLLER 6-3
6.3  General considerations, power supply network
All devices running on AC current are affected by frequency. As a non-sine wave is the result of a fundamental wave plus a 
series of harmonics from this fundamental wave, we can infe r that devices running on AC current are influenced by the 
applied waveform.
For a correct testing of relays running on AC current, it is fundamental to...

6.4 ISOLATION TESTS CHAPTER 6:  COMMISSIONING
6.4  Isolation tests
During all tests, the screw located on the rear of the relay must be grounded.
For verifying isolation, independent groups are created, and voltage is applied as follows: 
2200 RMS volts will be applied progressively among all terminals in a group, short-circuited between them and the 
case, during one second.
2200 RMS volts will be applied progressively between groups, during one second....

GEK-113000-AFF650 DIGITAL BAY CONTROLLER 6-5
6.5  Indicators
Feed the relay and verify that when commanding a LED reset operation, all LED indicators light up and they are turned off 
when pressing the ESC key for more than 3 seconds.
6.6  Power supply testing
Feed the relay with the minimum and maximum voltage. For each voltage value, verify that the alarm relay is activated 
when there is voltage, and it is deactivated when there is no feed. If the power supply...

6.8  Verif ication of measurement
Set the relay as follows
NOTE:
ALL ANGLES INDICATED ARE LAGGING ANGLES 
ALL VALUES OBTAINED IN THIS TEST MUST BE  THE ONES CORRESPONDING TO THE PHASOR ONES
6.8.1  Voltages
Apply the following voltage and frequency values to the relay:
Verify that the relay measures the values with an error of ±1 % of the applied value from 10V to 208V.

Percent of Load-to-Trip
The relevant actual values displays are shown below:
Actual > Metering > Primary Values > Current > % of Load-to-trip
Note Percent of load-to-trip is calculated from the phase with the highest current reading. It is the ratio of this current to 
the lowest pickup setting among the phase time and instantaneous overcurrent protection features. If all of these features 
are disabled,...

6.9  Inputs and outputs
During all tests, the screw on the rear of the relay must be grounded.
6.9.1  Digital inputs
During this test, the user determines the activation/deactivation points for every input in the relay for the set voltage value  
of 30 Volts.
Verify that the error does not exceed ± 10% (+10% on activation, -10% on deactivation).
Default board settings for the input test can be modified in...

6.9 INPUTS AND OUTPUTS CHAPTER 6:  COMMISSIONING
6.9.2  Contact outputs
The correct activation of every output to be verified.
For every output, activation command of a single contact must be given, and then verify that only that contact is 
activated. Go to EnerVista 650 Setup Software (Setpoint > Inputs/Outputs > Force Outputs).
For switched contacts, the change of state of both contacts shall be verified.
