The relays are intended for automatic turning the wipers ON as soon as rain drops appear on the wind screen. They are also intended for control of interrupted operation of wiper relay and joined operation of screen washer and screen wiper.
The relays are used on the following cars: VAZ-2108, -2109, -2110, -2111, -2112, Niva-Shevrole, AZLK 2141, Svyatogor, IZH2126, UAZ 3160 (old fuse block).
Wiper relay with interval control, rain sensor and connective flexible cable are included into the set. Rain sensor is equipped with a button for adjustment and LED indicators (of different colors).
SETTING AND INSTALLATION
1 Installation
Rain Sensor (ДД) should be installed at temperature not lower than 15°С!
1.1 Clean and dry the place on the windscreen inside the car (behind the rear-view window).
1.2 Stick the sensor case (with its cable up) so that the sensors will be located in the transparent zone of wipers operation.
1.3 Lay the cable under the car frame towards the relay block (through the door seal if necessary).
1.4 Install the wiper relay case on the place of regular one.
2 Operation
2.1 Turn the ignition ON. LEDs will show the current operation mode: green- rain; blue- snow; no color – operation in the interval control mode.
Blue LED blinking means that interrupted mode is ON. Turn the under-wheel witch into OFF position. Operation mode choice is done through short pressing of the button.
2.2 Choose the level of sensitiveness by long pressing of the button (more than 3 seconds). Mind the number of LED blinks: ( 1 blink – low level, 2 or 3 - medium, 4 - high). Release the button as soon as necessary level has been shown.
The chosen operation mode and sensitiveness level is saved when the power is OFF.
2.3 Turn the interrupted operation mode ON.
3 Operation with interval control.
3.1 Turn the switch to “interrupted mode” – standard interval will be ON (about 5 seconds between the strokes of the wipers.
3.2 To change the interval turn the switch to OFF position and turn it into “interrupted mode” again after the necessary interval.
3.3 The other way of interval correction is possible. Turn the switch to “continuous mode” and with the first wipers stroke turn it back to “interrupted mode”.
The interval will be equal to the time between the last wipers stroke and turning to “continuous mode”.
The interval may be changed at any time by repetition of items 3.2 or 3.3.
Note
Wipers movement starts with 0,5 seconds delay (this allows to accumulate water before the first stroke). The wipers perform three strokes.
