Shock Resistance
The weighing platform has a robust design; however, falling weighing samples, side
impacts and shocks should be avoided. The weighing platform can withstand loads
specifi ed in the DIN standard IEC68 Part 2-27.
Notes on Planning Superstructures
3
Superstructures must be completely attached before the weighing platform is
connected to the power.
The weighing platform is designed for system integration. Scale drawings are the
basis for the selection of the required superstructures. The fi xing of model CAH*IG*
weighing platforms should be carried out using the YAS04IS fastening kit.
Moving or rotating parts on the weighing pan must be designed so that the
weighing results are not infl uenced. Rotating parts should be counterbalanced,
for example.
The weighing pan must be free on all sides so that there is no connection between
the weighing platform and fi xed parts due to falling parts or dirt. Cables and hoses
between the weighing platform and other devices may not exert any forces on the
weighing platform. These cables may not touch the weighing pan.
When setting up systems in hazardous areas (Zone 2 or 22), any relevant
specifi cations should be observed, e. g.: EN60079-14.
The design should ensure that moving parts do not cause electrostatic discharges
(e. g. roller conveyors).
Preload Range (Zero Set Range)
The weight of the superstructures that are attached to the weighing platform is
designated as a “preload.” The preload is electronically compensated for in the
weighing platform so that the full weighing range remains available and thus
zeroing and/or calibration/adjustment (with external weights) is possible.
Greater preloads reduce the weighing capacity. You may not fall below the following
weighing range values:
– For CAH*E-16ED... and CAH*E-32ED... a min. 20 kg weighing range must be
maintained
– For CAH*E-64ED... and CAH*G-64FE... a min. 35 kg weighing range must be
maintained
– For CAH*G-150IG-H and CAH*G-300IG-H a min. 60 kg weighing range must be
maintained
The preload must always be set before verifi cation.
Acclimatizing the Device
Condensation can form on the surfaces of a cold device when it is brought into a
substantially warmer area.
t Allow the device to acclimatize for about 2 hours at room temperature, leaving
it unplugged from AC power.
