Figure 2-1. Main Power Disconnect Switch
1. Main Power Disconnect Switch - This switch,
when in “ ” off position, disconnects power to
all circuits. Switch must be in “ ” on position to
operate any circuit. Turn switch “ ” off when
transporting MEWP.
2.2-2 Tilt Alarm
The MEWP is equipped with a device which senses
when the MEWP is on a slope in any directio
n. It is
designed to prevent driving and activate audible and
visual alarms when MEWP is on a slope greater than a
predetermined limit.
WARNING
If the tilt alarm sounds and the
platform does not, or only partially
raises, immediately lower the platform
completely and ensure that the MEWP is
on a firm level surface.
2.2-3 Lowering Alarm
The MEWP is equipped with an audible alarm which
sounds while the MEWP is lowering.
NOTE
On MEWP with certain options, a flashing
amber light will accompany this alarm.
2.2-4 Load Sensing System
This system is a safety device that will prevent any
normal movement of the MEWP from a stationary
working position after the rated load is reached and
exceeded. Refer to
Table 4.4 for maximum platform
capacities.
• When 90% of the rated load is reached:
The red power indicator light on the platform
control console flashes.
• When the rated load is reached:
An audible alarm sounds for approximately 2
seconds, 5 times per minute.
• When the rated load is exceeded:
The flashing light and audible alarm continue
and all electrically controlled MEWP movement
functions stop. To resume normal operation,
remove the overload from the platform.
• If the MEWP comes in contact with an overhead
obstruction:
The platform could become overloaded and all
functions would stop. Release of the platform
from this situation can only be effected by use
of the emergency lowering system. Refer to
Section 2.6.
NOTE
After reaching full extension and upon
lowering, the MEWP could stop and take
an overload reading. Return the controller
to the neutral center position, and release
the enable trigger switch. If the MEWP
is overloaded, the flashing light and
audible alarm continue and all electrically
controlled MEWP movement functions
stop. To resume normal operation, remove
the overload from the platform.
