Products > TYRE PRESSURE MONITORING
Spal tyre pressure
monitor is a safety system that warns drivers if their tyre
pressure has dropped below the manufacturers recommended
inflation level.
When a vehicle has low tyre pressure the
driver is alerted by a warning buzzer and visual display mounted
on the dashboard.
Suitable for vehicles with tyres inflated
to between 1.9 – 3.1 bars
FUNCTIONS
/ HOW IT WORKS?
Green:
When ignition is turned on, the monitoring LED
illuminates green for 2 seconds and the warning buzzer
beeps. When driving, pressure data is received from the
four sensors mounted in the vehicles tyres. During
driving with normal tyre pressures the LED will
permanently illuminate green.
Amber:
If a tyre begins to deflate and the pressure drops 0.3
bars then the LED will flash orange and the warning
buzzer will sound. This will indicate to the driver that
at least one tyre needs to be checked.
Red:
If the pressure in the deflating tyre drops a further
0.4 bar the LED flashes red and the audible buzzer
sounds for 10 seconds.
When the vehicle is stationary the system stops measuring
pressure.
INSTALLATION / AUTO-LEARNING
The pressure sensors are fitted in the same
way as a standard tyre valve.
The control unit requires a live, earth and
ignition power supply. When powered up the control unit enters
an auto-learning procedure (LED flashes green), in order for the
control unit to recognise the four pressure sensor the vehicle
must be driven for approximately 10 minutes above 35 KM/h , the
buzzer will sound periodically to confirm that the control unit
is receiving data from the tyre sensors. The LED will
permanently illuminate green when the auto-learning procedure is
complete.
SYSTEM DIAGNOSTICS
Whilst monitoring the tyres pressure the
unit also performs self diagnostic checks, in the event of one
or more sensors failing the LED will permanently illuminate
amber.
