4.3 Safety features - Movement
cut out
Operation of safety features
The operating principle is identical for all safety features
in case a non authorized movement is controlled :
- Orange indicator lit to indicate the prohibition
to the operator.
- piloting of the "Pump Inhibit" function of the
controller : the pump does not turn whatever
the condition of the others controller inputs
(parameter "Test 10" of the controller = CL -
see § 4.5).
- Supply cut to the coil [DV1].
NOTE
Tilt and slack chain : continuous detection.
Stability control : static detection.
È
:
Non authorized movement.
(1) : Movement speed reduction.
(2) : As long as the telescope is not retracted.
Operation of the relays
- Normal situation :
ç
relay(s) supplied, corresponding Led lit.
Additional relay (k6)
: supplied when a non
authorized movement is controlled.
F
UNCTION
: cuts the supply to the coil [DV1].
Relay k9
: authorizes static detection of the stability
control.

4.2.8.3 Steering angle sensors [SW41 & 42]
The sensor NC contacts are wired in series. The
sensor NO contacts are wired in parellel.
During a high speed drive (
), steering the wheels
at more than 45° actuates one of the sensors, causing
a NO contact to close. Entry [E12] of the
temporisation module is then supplied (see § 4.9).
Supply to this entry causes the desactivation of the
output [E11] : supply cut to the coil [HI-LO] - switch
to 2
nd
drive speed (
).
When the platform has left its transport position, the
relay K13 coil on the emergency control panel is no
longer supplied and the NC contacts of the sensors
[SW41] and [SW42] start to function : opening of one
of the NC contacts causes the signal between the
entry/output [E5] and [E7] on the temporisation
module to be cut (see § 4.9).
The drive movements are no longer available if the
wheels are steered at an angle above 45° before the
platform leaves its transport position (one of the NC
contact open) :
ç
Supply (+) to the coil [DV1] is cut
ç
The function "Pump Inhibit" of the controller
is actuated when a drive movement is controlled
(parameter TEST 10 of the controller = CL
- see §4.5).
NOTE
The sensors [SW39] AND [SW40] must be
actuated before the sensors [SW41] and
[SW42].
