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.

SFT2841: input, output, indicator status

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.
