Contact Outputs; Circuit Continuity Supervision Inputs; Latching Circuits - GE Multilin W650 Instruction Manual

11.8 INPUTS AND OUTPUTS
The correct activation of every output will 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 (Settings>Inputs/Outputs>Force Outputs).
For switched contacts, the change of state of both contacts shall be verified.
Supervision inputs will be tested as normal inputs, revising the voltage level that will be 19 Volts.
Coil 1:
Apply 19 Vdc to both 52/a (terminals F1-F2) and 52/b (terminals F3-F4)"Coil 1" circuit supervision inputs and verify that
they are activated.
Apply -19 Vdc to both 52/a (terminals F1-F2) and 52/b (terminals F3-F4)"Coil 1" circuit supervision inputs and verify
that they are activated.
Remove voltage from both inputs and verify that it takes them 500 ms to change state (deactivate).
Coil 2:
Apply 19 Vdc to both 52/a (terminals F15-F16) and 52/b (terminals F17-F18)"Coil 2" circuit supervision inputs and
verify that they are activated.
Apply -19 Vdc to both 52/a (terminals F15-F16) and 52/b (terminals F17-F18)"Coil 2" circuit supervision inputs and
verify that they are activated.
Remove voltage from both inputs and verify that it takes them 500 ms to change state (deactivate).
Send a closing command to the latched contact (F31-F33).
Make circulate a current of 200 mA through the contact in series with the sensing terminal.
Send an opening command and verify that the contact does not open.
Interrupt current and check tha the contact is released.

Repeat the test for the other latched contact (F34-F36).
