10. Commisioning
The description following hereafter is a short
instruction for the commissioning of the high-
pressure nozzle system.
In this form, it is primarily ment for recommis-
sioning after decommissioning of the system.
For
initial
start-up
of the unit by the com-
pany in charge for the installation of the noz-
zle system, a much more detailed document
is available with the title „Installation and ini-
tial operation instructions for HygroMatik adi-
abatic humidification systems“.
Improper installation hazard!
Start-up of the high-pressure nozzle system
is restricted to HygroMatik staff or authorized
personnel only.
Risk of electrical shock!
Hazardous electrical voltage!
Follow safety instructions for work on live
components.
Commissioning steps
Prior to
Initial start-up
, the prerequisites
required on-site must be met. Pls., confirm by
the notification of readiness form attached at
the end of the section (sent by fax or e-mail)
that this is the case.
Step 1: Check wiring and hose connec-
tions
»
Check that all electrical wire connec-
tions are tight and secure.
»
Check hose connections for secure
clamping and safe connections.
Step 2: Switch-on the high-pressure noz-
zle system
»
Switch on main breaker.
»
Open water supply stop cock.
»
Switch on unit by setting control
switch to “I”.
»
close safety (interlock) system
Step 3:
The unit performs a self-test and,
then, commences normal operation
•
During self-test, the On/Off button icon
flashes for a couple of seconds
•
On completion of the test, the commis-
sioning screen is shown in the display
for the basic unit settings (such as lan-
guage, time and date, type of control
signal and type of control). On this
screen the respective settings must be
made except when the settings have
been made ex factory according to the
order options ( for parameter setting, s.
section 12.2 „Screen 1 - Initial opera-
tion“ in the „Operation of control“ chap-
ter).
•
Consequently, normal operation is
commenced. However, humidification
or cooling is not started without a
demand pending
Step 4: Trigger demand
»
Set control to 1-step operation, i.e.
permanent demand in the corre-
sponding parameter in the display.
»
Close safety (interlock) system.
»
Place bridge or switch between ter-
minals 3 and 5 (main board).
•
The high-pressure pump starts opera-
tion and transfers water to the nozzles
with a pressure of up to 75 bar.
•
Water is atomized by the nozzles.
