**F21-4D: 3 independent COM lines (Up/Down & U/D 2S, East/West
& E/W 2S and R0)
**F21-4S/4SB: 3 independent COM lines (Up/Down, East/West and

Swapping COM & MAIN
According to the standard wiring diagram, all relays including the
MAIN relay will be turned off when the EMS is pressed. However, it
won’t work correctly when a pushbutton is programmed as a ”Toggle”
or “On/Off” function with “Bypass EMS”. Therefore, the MAIN and
COM must be swapped.
Changing R0/Start N.O. into N.C.
The N.O. (Normally Open) is a default output. If a N.C. (Normally
Closed) is necessary, to remove the wire No.11 (R0/Start, pink color)
and then insert it into the wire No.12 position on the wire cable
connector.
