IMPORTANT
Most analogue sensors are connected to the –Vin line of the vehicle power system. So, if the –Vin line
is disconnected (e.g., by a disconnecting switch), the state of the analogue input will be undefined and
analogue readings will not be considered to be valid. Therefore, if the tracker is connected to the vehicle
power system via a disconnecting switch, it is highly recommended to connect the analogue sensors via
a relay.
It is recommended to use a relay intended to switch dc circuits and with operating voltage
equal to voltage of vehicle power system. For example, 901.3747 relay, designed by AVAR Corp.
(www.ellink.ru/co/avar) for 24 V vehicle network.
