▶Volume Sensitive INT (Intermittent) Wiper
For RKSTICS without the rain sensor, perform the following operation:
Controls the wiper intermittent operation by the values from the vehicle\
speed and the volume
(resistance).
-
Calculates and converts the Intermittent interv al automatically by obtaining the INT VOLUME
when the ignition switch and the INT switch is in the "ON" position.
The wipers are operated in vehicle speed sensitiv e mode when turning the INT switch to the
"ON" position with the engine running or starting the engine with the INT switch positioned to
"ON".
Intermittent interval (at 0 km/h): 3 ± 0.5 ~ 19 ± 2 seconds

Vehicle speed calculation
-
[Input the vehicle speed]
It is calculated by the numbers of input pulses for one second.
VOLUME calculation
-
The pause time of the vehicle speed sensitive INT wiper is calculated by\
the INT volume (inpu
t
voltage). Each level has the hysteresis.
˙
Pause time calculation
-
Pause time means the duration that wipers are stopped at parking positio\
n.
Elapsed time means the duration after the wiper motor started to operate from parking
position.
The pause time is calculated by the vehicle speed and the VOLUME.
※If the pause time is below 1.0 second, the wipers operate without pause.
※If the pause time is over 1.5 seconds, the wipers operate intermittently.

3. CAUTIONS ON RAIN SENSOR
When the wiper switch is in the AUTO position, the wiper will operate for 1 cycle if the initial engine
start is made. This may cause the wiper blades to wear prematurely. Therefore, other than rainy days,
set the switch to the OFF position. Especially during the winter time, check if the wiper blades are not
frozen to the windshield.
Operating the wiper with the blades frozen can damage the wiper motor.
If you operate the wipers when the windshield is dry without spraying washer fluid, the windshield can
be scratched and the wiper blades can wear prematurely. Use the wiper with the washer fluid when
the windshield is dry.
When it does not rain, turn the wiper switch to the OFF position.
Turn the wiper switch to the OFF position before any car wash to avoid unwanted operation of the
wipers. -

-
When cleaning the windshield over the sensor with damp clothes, the wiper may operate suddenly. It
could cause serious injury. Make sure to place the wiper switch to the OFF position and ignition
switch OFF when not in use.
Irregular operation (abrupt operation) ▶
Check if the sensor is off the position.
Check if the rain sensor cover is securely installed.
Check if the customer is familiar to how to control the wiper sensitivity.
Check if the wiper sensitivity control is set to the FAST side (step 5).
Check the wiper blade for wear.
If the wiper blade cannot wipe the glass uniformly and clearly, it may cause the rain sensor to work
irregularly. Therefore, in this case, replace the wiper blade with a new one. -

7) Speed Sensitive INT Wiper
Calculates and converts the Intermittent interval automatically by obtaining the INT VOLUME when
the ignition switch and the INT switch is in the "ON" position.
The wipers are operated in vehicle speed sensitive mode as soon as turning the INT auto switch to
the "ON" position with the ignition key ON or turning the ignition key to the "ON" position with the INT
auto switch ON.
This applies to the vehicle without the rain sensor. -

Controls the wiper intermittent operation by the values from the vehicle speed and the setting value.
