Blocking Cancellation - Zetor FORTERRA HSX 100 2014 Operator's Manual

BLOCKING CANCELLATION

When you switch on the electric installa-
tion with the key of the switching box (I),
the lifting device remains blocked elec-
tronically - the lifting and lowering func-
tion is deactivated; on the EHR-B control
panel the diagnostic LED (7) and the vi-
bration dampening LED (11) shortly light
up - the system self-test is in progress.
The lifting LED (8) and the lowering LED
(9) are off. After a short time permanent
illumination of the diagnostic LED (7) in-
dicates the state of EHR-B blocking.
If the diagnostic LED (7) is permanently
illuminated, the control circuits are dis-
connected.
ELECTRO-HYDRAULIC SYSTEM

The engine can only be started
if the engine (1) is in position
(b).
The EHR-B electro-hydraulic system is
only active when the engine is started.
Activation of the EHR-B system is only
possible when the lubrication indicator
has gone off.
The blocking can only be cancelled (sys-
tem activated) with the engine running by
moving the lifting lever (1) to position (a)
- short-time switching is sufficient.
By moving the lever (1) to position (c)
you will bring the three-point hitch to the
position corresponding to the element
setting, i.e. the current position of con-
trols (4), (5), (6).

After the activation of the system
EHR-B first for safety reasons
limits the lifting speed of the hy-
draulic arms.
When the hydraulic arms first
reach the selected position, this
safety limitation is cancelled and
then the lifting speed of the hy-
draulic arms is normal.
