2.4 Start Procedures for the F21-4S, F21-4D, F21-6S:

1. If the red STOP knob is pushed in, turn it clockwise about 45 degrees to reset it and allow

it to pop up. This knob must be in the up position in order to operate the transmitter.

2. Put the green key into its slot in the front of the transmitter, next to the red STOP knob.

3. Turn the green key clockwise. The green key must go past the ON position detent, to the

START position. Then release it and it will spring back to the ON position.

4. Use the pushbuttons to control the equipment. The model F21-4D uses two-step

pushbuttons; pressing them to the first detent will activate the equipment at the slow

speed, and pressing them fully will activate the equipment at the fast speed.

5. Press the red STOP knob or turn the green key to OFF to stop movement immediately

and drop out the mainline contactor.

6. Turn the green key to OFF and remove it whenever the transmitter is not in use to prevent

unintentional operation.

7. The F21-4 and F21-6 models have an extra relay in the receiver, labeled R0. Turning the

green key to START after the equipment has already been started will close this relay.

This relay will not engage the first time the key is turned to START when starting up the

equipment. See section 5.3 for detailed information on this option.
