Description
Sensor type: 0, 1, 2, and 3
0
indicates that any fuel sensor is not connected.
1
indicates that a C-type fuel sensor is connected (AD2).
2
indicates that a R-type fuel sensor is connected (AD2).
3
indicates that a V-type fuel sensor is connected (AD2).
For the MVT600 and T1, the AD2 connects to the fuel sensor by default.
Alert percentage upper limit: When the value is
0
, the alert is cleared. When the value is
not 0, GPRS and SMS event flags take effect automatically. When the fuel percentage is
higher than or equal to the value, an alert is generated, and the alert event code is 52.
Alert percentage lower limit: When the value is
0
, the alert is cleared. When the value is
not 0, GPRS and SMS event flags take effect automatically. When the fuel percentage is
lower than or equal to the value, an alert is generate, and the alert event code is 53.
If you want to modify a parameter, other parameters must be left blank and separators
(,) must be remained. If you only send the C47 command, all parameters are initialized to
0 and they are decimal characters.
R-type fuel sensor: resistance output fuel sensor
C-type fuel sensor: capacitance output fuel sensor
V-type fuel sensor: voltage output fuel sensor
Fuel sensors A53 and A54 are the V type of fuel sensor.
