Checking Logic Input &

Output Connections

Checking Logic Input Connections

PE50146

Procedure

Proceed as follows for each input:

1 If the input supply voltage is present, use an appropriate electric cord to short-

circuit the contact that delivers logic data to the input.

2 If the input supply voltage is not present, apply a voltage supplied by the DC

voltage generator to the terminal of the contact linked to the chosen input.

Observe polarity and level.

3 Use the Input, output, indicator status screen of the SFT2841 software to

observe the change of status of the input.

4 Press the SFT2841 Reset key as necessary to clear all messages and deactivate

all outputs at the end of the test.

Checking Logic Output Connections

PE50147

Procedure

This test uses the "Output relay test" function from the SFT2841 software in the

Sepam™ Diagnosis screen.

When it is used for the watchdog, only output O5 can be tested.

1 This function requires prior entry of the "Parameter setting" password.

2 Activate each output relay using the buttons in the SFT2841 software. The

activated output relay changes status over a period of 5 seconds.

3 Observe the change of status of the output relay through the operation of the

related switchgear, if it is ready to operate and is powered, or connect a voltmeter

to the terminals of the output contact. The voltage cancels itself out when the

contact closes.

4 At the end of the test, press the SFT2841 Reset key to clear all messages and

deactivate all outputs.
