During operation
During operation of the crane the capacity utilisation of the crane (from 60%) can be read off in
10% steps on the capacity utilisation indicator on the control panel of the Paltronic 50
60, 70, 80% LED green. 90% LED yellow (with acoustic warning).
100% LED red.
60 70 80 90 100
LED strip flashes when the crane is in the overload range.
LED strip does not light up when the Paltronic capacity utilisation is below 60% or “OFF“ (on /
off).
If your crane is equipped with a 2nd hinged system, the higher capacity utilisation is always
indicated
(2nd hinged system or elevating cylinder of the crane).
EMERGENCY - OFF switch
If unforeseen dangerous situations arise during operation of the crane the crane
can be switched off using the EMERGENCY - OFF switch which is integrated in the
system.
HPLS system
If your crane is equipped with an HPLS system this can be activated when required
using the appropriate button on the Paltronic 50 control panel.
HPLS
LED lights up green . When HPLS is switched on and the crane is in the HPLS range (HPLS
cannot be switched off).
LED flashes . When HPLS is switched on, but is not required. HPLS can be switched off.
LED is off . When HPLS is switched off or your crane is not equipped with HPLS.
OLP – Button
When the boom is moved to the stop and the load moment limiting system thus
responds (the crane is not really overloaded in this situation.), it is possible by
pressing the OLP button ( LED lights up green, OLP is switched on) to activate for
1.5 seconds the function “lower boom “ and also the function “lower 2nd hinged
system” .
OLP
After these 1.5 seconds the function “OLP button“ is blocked for 30 seconds (LED flashes) after
which the OLP function can be activated again for 1.5 seconds. The OLP button is blocked
for 30 seconds, to prevent misuse in an actual overload situation.
Intentionally increasing the load moment by using the OLP button is
prohibited.
In normal status the LED does not light up or flash. After the Paltronic 50 has been switched on the
LED flashes for 30 seconds.
