EZD
Target readership
EZD must only be installed and wired up by trained
electricians or other persons familiar with the installation of
electrical equipment.
A specialist knowledge of electrical engineering is needed for
commissioning and creating circuit diagrams. When
controlling active components such as motors or pressure
cylinders, parts of the system can be damaged and persons
put at risk if EZD is connected or programmed incorrectly.
Proper use
EZD is a programmable device that provides HMI, switching,
closed-loop and open-loop control functions, and can be used
to replace relay and contactor controls as well as being used
as an EZD device. EZD must be properly installed before use.
The display and operating unit of the EZD is protected to IP65
and does not normally require any special housing protection.
The rear EZD units are designed as mounting units and must
be installed in an enclosure, control cabinet or a service
distribution board. Both the power feed and the signal
terminals must be laid and covered so as to prevent
accidental contact.
The installation must comply with regulations for
electromagnetic compatibility (EMC).
The power up of the EZD must not cause any hazards arising
from activated devices, such as unexpected motor startups or
power ups.
Improper use
EZD should not be used as a substitute for safety-related
controls such as burner or crane controls, emergency-stop or
two-hand safety controls.
