7 - START-UP
The real unit flow is according to the aeraulic system features.
It is therefore necessary to check the air flow and in case to
set the parameter:
P57
FanSpeedOut
Before checking, make sure that the system has been
completed
In all its parts (shunts, dampers, grilles, diffusers etc.)
7.10 AIR FLOW SETTING
7.11 FIRE ALARM : CONFIGURATION
7.9 APPLICATIONS WITH TEXTILE DUCTING
It is possible to modify the fan start-up ramp to personalize it
in case of applications with textile ducting.
Set the parameter
P62
EnRampaEsp :
0
= disabile ramp
1
= slow ramp
10
= rapid ramp
It is also possible to set intermediate values.
•
Check that the remote commands (ON-OFF, etc.) are con-
nected and if necessary enabled with the relevant parame-
ters as described in ELECTRICAL CONNECTIONS sec-
tion
•
Check that probes or optional components are connect
and enable with the relative parameters( ELECTRICAL
CONNECTION section)
7.8 REMOTE CONSENT
It is possible to set the unit operating in case of an alarm si-
gnal from the fire signalling controller.
Par 151
TypeFireMode = complete unit shutdown
The unit cannot be used as smoke extractors.
7.12 STARTING REPORT
Realize the operating objective conditions is useful for check
the unit over time.
With unit of full load, namely in stable conditions and close to
those of work, take the following data:
•
Tension and general absorptions with unit at full load
•
Absorption of varied electrical loads (compressors, fans,
pumps etc)
•
Temperatures and capacities of different liquid (water, air)
in the inlet and outlet of the unit
•
Temperatures and pressures on the refrigerant circuit cha-
racteristic points (compressor discharge, liquid, intake)
The
remarks should be preserved and available during
maintenance .
97/23 CE PED DIRECTIVE gives instructions for installers,
users and maintenance technicians as well.
Refer to local actuation norms; briefly and as an example, see
the following
•
Compulsory verification of the first installation :
only for units assembled on the installer’s building site
(for ex. Condensing c direct expansion unit)
•
Certification of setting in service :
for all the units
•
Periodical verifications:
to be executed with the frequency indicated by the
manufacturer (see the maintenance section)
7.13 CE 97/23 PED DIRECTIVE
Check that the air and water temperatures are included in the
working limits
For information on the control system, refer to the paragraph
CONTROL.
Start the unit
With unit of full load, namely in stable conditions and close to
those of work, check :
•
Power supply tension
•
Total absorption of the unit
•
Absorption of the single electric loads
