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 use a current and/or voltage senoidal waveform. 
The pureness of a senoidal wave (lack of harmonics) cannot be  expressed specifically for a specific relay. However, any 
relay incorporating sintonized circuits, R-L and R-C circuits, is affected by non-senoidal waveforms, as in the case of F650. 
These relays respond to the voltage waveform in a different way to the majority of AC current voltmeters. If the power 
supply network used for the testing contains wide harmonics, the voltmeter and relay responses are different.
Relays have been calibrated in factory using a Network of  50 or 60 Hz with a minimum harmonic content. When the relay 
is tested, a power supply network with no harmonics in its waveform must be used.
The ammeters and chronometers used for testing the pickup current and relay operation time must be calibrated and 
their accuracy must be better than the relay’s. The power supply used in the tests must remain stable, mainly in the levels 
near the operation thresholds.
It is important to point out that the accuracy with which the test is performed depends on the network and on the 
instruments used. Functional tests performed with unsuitable  power supply network and instruments are useful to check 
that the relay operates properly and therefore its operating characteristics are verified in an approximate manner. 
However, if the relay would be calibrated in these conditions , its operational characteristics would be outside the tolerance 
range values.
The following sections detail the list of tests for verifying the complete relay functionality.

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.
WARNING: No communication circuit shall be tested for isolation.
Groups to be created depend on the type of modules included in F650, selectable according to the model.
The following table shows the different groups depending on the module type:

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
