Control cards
2.2.4 Sensor input
Sensors are used to provide added functionality when certain conditions are met or limit certain functionality
for safety reasons. The TLC B1 control card has input pins for up to 4 different sensors, S2 through S5. The S1
input is used to power the S5 so together they act as a single input. The S1+S5 input is most often used for the
auto tilt functionality on some variants.
The TLC B1 card can accomodate the sensor types shown in the table below. Different variants of the Z 1500/2000
use different types and number of sensors depending on functionality. See the functional descriptions and
schematics chapter for connection information.
Type
Digital angle sensor
(ball type)
Digital angle sensor
(liquid type)
Pressure sensor

Picture
An angle sensor that uses an articulating ball to
output an On/Off signal for certain angle ranges.
Usually mounted on the platform and used to con-
trol the two hand safety requirement.
A sensor that uses a fluid to measure the angle and
outputs an On/Off signal for certain angle values.
More accurate than the ball type sensor.
Mounted on the platform on tail lifts equipped
with digital auto tilt on which it is used to stop the
auto tilt up motion of the platform when it reaches
horisontal level.
Outputs an On/Off signal if the pressure exceeds
(rising pressure sensor) or falls below (falling pres-
sure sensor) a predetermined value.
It is most often used for the open platform alarm, in
which case it is mounted on the positive hydraulic
connection to the right tilt cylinder. It can also be
used for the auto tilt function in which case it is
mounted on the positive hydraulic connection to the
right lift cylinder.
