NOTICE Damage to electronic components due to electrostatic discharge (ESD)
Electronic components are becoming smaller and smaller and more and more
complex. Their susceptibility to damage from electrostatic discharge is increased
accordingly. Therefore:
▶
To protect the components, measures must be undertaken to prevent electrostatic
discharge during all work performed at the open device (ESD protection).
▶
To prevent static charges building up on the human body, service employees can
for example be equipped with a personal earthing system.
Transport to the place of installation
Avoid heavy impacts. Wherever possible, use the original packaging for transporta­
tion. The original packaging ensures safe transport.
Where there are extreme fluctuations of temperature and moisture, condensation can
cause moisture to build up within the device. This can cause an electrical short circuit.
After transportation of the device, do not put it into operation until the device, including
its internal parts, has acclimatised to the ambient temperature.
Skill levels of personnel for installation and commissioning
Installation and commissioning of the of the Dust and Opacity Monitor must be carried
out by skilled personnel (see section 2.4.1 Personnel, skills [
}
22] ):
●
Specialist staff, and for electrical work electricians with special knowledge of the
supply unit.
●
Service technicians can be involved for support as necessary.
The operating company must provide employees with training in the following areas:
●
operational hazards and how to prevent them
●
applicable regulations relating to the assigned work
●
tasks assigned and possible hazards due to incorrect behaviour.
Preparation for installation
The standard system consists of:
●
a D‑R 290 measuring head and the associated reflector
●
a D−BL purge air blower
●
optional: a second blower (D-BL …; e.g. for units with pitch circle diameter Ø
150 mm), see Fig. 5.1 D
●
optional (not shown): two D−SK 290 fail-safe shutters one each for the measuring
head and the reflector
●
a D−ISC 100 universal control and display unit, see Fig. 5.1 A, B, D, E
●
optional: a supply unit (terminal box D-TB …) for power supply to the measuring
head and as a data interface, see Fig. 5.1 B, C, E
●
optional (not shown): a weather protection cover (as required for the measuring
head, reflector and blower)
Examples for the various system configurations can be found in Fig. 5.1 .
