5.3 Models F21-4S, F21-4D, F21-6S, F24-6S, F24-6D, F24-8S, F24-8D, F24-10S, F24-10D,

F24-12S, and F24-12D:

- R0 function. On the F21 models the R0 relay operates when the green key is turned to

START after the unit is already started. On the F24 models the R0 relay operates when

the START button is pushed after the unit is already started. It is by default set to

momentary (closed when START key is turned on the F21 models or START button is

pressed on the F24 models, open when released). It can also be set to toggle (turn the

START key once to close, turn it again to open on F21 models or push the START button

once to close, then push the button again to open on the F24 models), or inching (does

not activate the R0 relay, but instead only allows pushbuttons pressed after turning the

key to remain on for a preset length of time, no matter how long the button is held). For

inching, the inch time may be set from 0.05 to 0.8 seconds in 0.1-second increments.

Typical selections are available on the programming data sheet.

5.4 Other Programming options for the F24 UP/DOWN 2 Step Buttons:

 Dual Motor. When the first detent of the button is reached the first step relay turns ON,

when the button is fully depressed the second step relay turns ON and the first step relay

turns OFF. When the button is released back to the first detent, the first step relay will

turn ON until the button is released.

 Dual Motor (1). Works the same as Dual Motor, with the difference being the first step

relay will not activate when returning from fully depressed to the first detent. The button

must be completely released and repressed in order to activate the first step relay again.

 Combination. When 2 buttons are depressed simultaneously, it will result in a third

relay output that is set to toggle. The relays of the two buttons depressed will not engage,

instead a third relay will engage. This feature is designed to suit some special

applications such as lighting systems. Combination setting is prohibited for magnetic

devices. Combination setting is always set to controlled by stop. Uncontrolled by stop is

not available.

 3 Speeds. The START button can be used to control a third speed. Once the motion

button (either up or down) is fully depressed, a third speed can be obtained by pushing

the START button.
