Function
1.
Behavior of Combined WALK IN SWITCH
ASSIST SEAT SLIDE/RECLINE/HEADREST can be controlled by Combined WALK IN SWITCH
(1)
Control by Combined WALK IN FRONT SWITCH
In case of Combined WALK IN FRONT SWITCH is kept ON
A.
RPSM drives ASSIST SLIDE motor forward and ASSIST HEADREST motor down.
B.
RPSM drives ASSIST RECLINE forward when ASSIST SLIDE FRONT LIMIT ON.
C.
BUZZER output 1 time when ASSIST SLIDE FRONT LIMIT & ASSIST RECLINE FRONT LIMIT.
D.
If Combined WALK IN FRONT SWITCH is OFF>ON in above state (3), BUZZER output 1 time.
But no output ASSIST SLIDE&RECLINE motors.
E.
If Combined WALK IN FRONT SWITCH and MAMUAL SWITCH are simultaneously ON, RPSM Drives for MANUAL SWITCH.
F.
RPSM stops ASSIST seats motor output immediately, when Combined WALK IN FRONT SWITCH is ON > OFF. (Combined WAL KIN SWITCH : SELF RETURN TYPE SWITCH )
G.
Behavior of Combined WALK IN FRONT SWITCH is not available when ASSIST DOOR OPEN.
(2)
Control by Combined WALK IN REAR SWITCH
In case of Combined WALK IN REAR SWITCH is kept ON
A.
RPSM drives ASSIST RECLINE motor backward to STD Position(400 Pulse(20°) from REAR LIMIT).
B.
RPSM drives ASSIST SLIDE motor backward to REAR LIMIT when ASSIST RECLINE is at STD position. And then BUZZER output 1time.
C.
No output for ASSIST HEADREST as Combined WALK IN REAR SWITCH.
D.
If Combined WALK IN REAR SWITCH is OFF>ON when ASSIST RECLINE is at STD position and ASSIST SLIDE REAR LIMIT, BUZZER output 1 time. But no output ASSIST SLIDE&RECLINE motor.
E.
If Combined WALK IN REAR SWITCH and MAMUAL SWITCH are simultaneously ON, RPSM drives assist seat motors for MANUAL SWITCH.
F.
RPSM stops ASSIST seats motor output immediately, when Combined WALK IN REAR SWITCHis ON > OFF. (Combined WAL KIN SWITCH : SELF RETURN TYPE SWITCH )
G.
Behavior of Combined WALK IN REAR SWITCH is not available when ASSIST DOOR OPEN.
2.
Behavior of Combined RELAX SWITCH
ASSIST SEAT SLIDE/RECLINE/HEADREST & VIP SEAT SLIDE/LEG SUPPORT can be controlled by Combined RELAX SWITCH
(1)
Control by Combined RELAX FRONT SWITCH
In case of Combined WALK IN FRONT SWITCH is kept ON
A.
RPSM drives ASSIST SLIDE motor forward, ASSIST RECLINE forward and ASSIST HEAD REST motor down. If ASSIST RECLINE position reaches to 900 Pulse from REAR LIMIT (RECLINE angle : 90°), RPSM drives VIP SEAT SLIDE forward.
B.
RPSM drives VIP SEAT LEG SUPPORT motor up when VIP SEAT SLIDE FRONT LIMIT ON.
C.
BUZZER output 1 time when ASSIST SLIDE/RECLINE, VIP SEAT SLIDE FRONT LIMIT and VIP SEAT LEG SUPPORT UP LIMIT.
D.
If Combined RELAX FRONT SWITCH is OFF>ON in above state (3), BUZZER output 1 time.But no output ASSIST and VIP SEAT motors.
E.
If Combined RELAX FRONT SWITCH and MANUAL SWITCH are simultaneously ON, RPSM Drives for MANUAL SWITCH.
F.
RPSM stops motor output immediately, when Combined RELAX FRONT SWITCH is ON>OFF.
(Combined RELAX FRONT SWITCH : SELF RETURN TYPE SWITCH)
G.
Behavior of Combined RELAX FRONT SWITCH is not available when ASSIST DOOR OPEN.
(2)
Control by Combined RELAX REAR SWITCH
In case of Combined WALK IN FRONT SWITCH is kept ON
A.
RPSM drives VIP SEAT LEG SUPPORT down and SLIDE backward. If they reach to LIMIT, RPSM drives ASSIST RECLINE backward to STD Position(400 Pulse(20°) from REAR LIMIT).
B.
RPSM drives ASSIST SLIDE motor backward to REAR LIMIT when ASSIST RECLINE is at STD position.
C.
BUZZER output 1 time when ASSIST SLIDE REAR LIMIT
D.
If Combined RELAX REAR SWITCH is OFF>ON when ASSIST RECLINE is at STD position, ASSIST SLIDE REAR LIMIT, VIP SEAT SLIDE REAR LIMIT and LEG SUPPORT DOWN LIMIT, BUZZER output 1 time. But no output ASSIST and VIP SEAT motors.
E.
If Combined RELAX REAR SWITCH and MAMUAL SWITCH are simultaneously ON, RPSM Drives for MANUAL SWITCH.
F.
RPSM stops motor output immediately, when Combined RELAX REAR SWITCH is ON>OFF.
(Combined RELAX REAR SWITCH : SELF RETURN TYPE SWITCH)
G.
Behavior of Combined RELAX REAR SWITCH is not available when ASSIST DOOR OPEN.
3.
Maximum Driving Time of ASSIST SEAT motors
A.
Slide : 20s +/- 2s
B.
Recline : 35s +/- 3s
C.
Head Rest : 10s +/- 1s
4.
Set LIMIT
(1)
HARD LIMIT SW
A.
HARD LIMIT SW prevents MOTOR restriction, Electrical contacts type is NORMAL CLOSE.
•
ASSIST SLIDE/RECLINE, VIP SEAT SLIDE/LEG SURPPURT
B.
When HARD LIMIT SW of ASSIST SLIDE/RECLINE, VIP SEAT SLIDE/LEG SURPPURT is close > open, LIMIT is renewed when they estimate end position of machinery.
(2)
SOFT LIMIT SW
A.
SOFT LIMIT is applied because it prevents MOTOR restriction. (HEADREST(Spare Seat))
B.
SOFT LIMIT deals with HEADREST, First it moves all section so it renewed LIMIT position.
C.
Renewal conditions of LIMIT are first all section to move, LIMIT set up when HALL SENSOR don’t input (1sec of 6PULSE)
D.
After LIMIT was renewed, if OUTPUT don’t generate 6PULSE upward that it is ERROR condition.
5.
ERROR detection and transaction
(1)
ERROR detection
ERROR is detected when as follow conditions are occurred for each MOTOR operation by MANUAL SW
A.
ERROR when no pulse input

•
Each MOTOR output stops when ERROR occurred during the MANUAL SW operation
(Exclusive of SLIDE, RECLINE)
B.
In case of SENSOR VCC of SEAT detects under 2.5V for 40ms
=> In this case SENSOR VCC of SEAT detects over 3.5V, then reversion
C.
No buzzer output although error is occurred
(2)
ERROR transaction
When error detected as above, HARNESS disconnection or SENSOR fault, behavior of Error transaction is as follows.
A.
ERROR is decided when HALL SENSOR don’t input during MANUAL SW operation.
B.
ERROR is recovered if MANUAL SW operates in MOTOR to occur ERROR
C.
Recovered timing is decided when troubled MOTOR is repaired, it’s like as follows
SEAT : In case, Normal SIGNAL [6PULSE input within 3sec(RECLINE) / 1sec(HEADREST)] input from POSITION SENSOR that Controls of MANUAL SW cause MOTOR ERROR
