F-16 CONTROLS

CALIBRATION EXAMPLE

Determine setpoint value on an SW-50 Series Speed Switch — on the bench

J Turn on the F-16.

J Set the F-16 to a low frequency—below what would be expected to trip that

setpoint.

J Attach the red F-16 lead to Terminal 3 on the SW-50.

J Attach the black F-16 lead to terminal 2 on the SW-50.

J Make sure the F-16 is set to GENERATOR.

J Slowly increase the frequency on the F-16.

J Using an ohmmeter across each relay contact, in turn, determine the frequency

at which the relays change state.

Note: An overspeed relay will latch if terminal 4 is not grounded.

Change setpoint value on an SW-50 Series Speed Switch — on the bench

Remove the screws in the access holes for the required setpoint adjustment trim pots.

J Set the signal generator to the frequency at which the relay should change

state.

J Using a small, flat blade screwdriver, slowly adjust the trim pot for the

appropriate relay until the relay changes state.

• CW to increase the setpoint value

• CCW to decrease the setpoint value

J Decrease the frequency, then slowly increase it to verify that the relay trips at

the appropriate point.
