This option allows the user to turn on the optical wiper automatically during the sensor
power up.
4. Wiper Option Autowipe
(8.3.1.A4)
This option allows the user to set up a periodic optical wipe interval. When Auto-wipe is not
in-use, please select “OFF”.
5. Power On Raw Output
(8.3.1.A5)
This option is valid for the Analog Output option only. During the power-up process, the
sensor outputs the set Analog value (may take up to 2 seconds, 12 seconds when power-
on wiping). The value is a raw value related to the Analog section described in Section
8.2.4 “Measurement via Analog Interface”
.
6. Set
(8.3.1.A6)
Select “Set” once the wiper configuration is completed.
7. Test functions for the Optical wiper system
(8.3.1.A7)
This Option allows the user to test the optical wiper operation when attached to the
calibration software. Some of the operations are: drive forward, backward, break and
standby.
8.3.2.
Recommended method of triggering the optical wiper
using a dedicated wiper wire
This section describes internal electrical characteristics of the wiper wire and recommended
methods of triggering the optical wiper action by shorting the wire to the power ground.
•
Please refer to Figure section
(8.3.2.A1)
for internal characteristic for the calibration
wire/wiper wire.
•
Please refer to Figure section
(8.3.2.A2)
on recommended use of the wiper
activation wire using a relay output or using a NPN transistor.
