CW/CCW (Right / Reverse direction).
Description
- The operation of TRIAC1 is the same as
that of the driving system.
- If the electric potential of R39 is grounded
(0V), TRIAC1 turns on.
- CN1 detects if the door is locked or
unlocked. If unlocked, it does not apply
power to the motor even if TRIAC1 turns on.
- If the door is unlocked and TRIAC1 turns on,
the motor connected to CN4 is supplied with
power and drives CW (right direction).
- Under such conditions, turning RELAY3 on
will drive the motor CCW (reverse) as the
wiring is switched to CCW.
- Turning RELAY4 on will switch the winding
