STARTUP / PROGRAMMING
Preliminary Checks
Upon delivery on site the equipment must be inspected for
damages occurred during transportation.
As a minimum, the following points must be inspected:
•
Integrity of connections and equipment sealing
•
Status of painted surfaces. If paint is damaged any
touch-ups must be carried out in accordance with the
project coating specification
•
Visual check of critical areas such as pipe plugs, level
gauge connection, etc
Any damage shall be reported to the project team and to the
vendor in order to agree and coordinate any repair work.
The pneumatic panel has been subject to a hydrostatic
test at the factory according to applicable codes and
thoroughly inspected for leakage during that test. However,
handling during transportation or moving into place may
have loosened gasket seals therefore it is recommended to
recheck all bolted connections prior to start up.
Equipment operating at high pressure should be warmed up
slowly and uniformly before applying full pressure.
Calibration of the cylinder tank is particularly sensitive to
very rapid pressure increase. Pressure should be increased
in stages of approximately 10% of operating pressure up to
the operating value. In case of leakage or other issues, the
procedure should be immediately stopped and the problem
investigated and solved before a new startup.
Before startup and after the initial startup, at normal
operating pressure and temperature, it is recommended to
inspect all gasketed joints for tightness.
Before switching on the electronic control unit, it is necessary
to define and set the Gas Volume/Gas Delivery signal type.
The control unit can acquire a BF pulse Gas Volume signal
(Standard Configuration) or an Analog Gas Instantaneous
Delivery signal 4-20 mA (to be configured).
To configure an Analog Instantaneous Delivery signal
proceed as follows:
•
Remove the metal protection on the signal acquisition
card located on the back of the cabin of the electronic
control unit;
•
Set the S1 micro-switch according to the following table:
1= OFF Gas Volume pulse input
1= ON
Analog Gas Instantaneous Delivery signal 4-20 mA
•
Second switch is used for control "Zero Gas Flow rate"
function
2= OFF Function disabled
2= ON
Function enabled - if the system detect, for 2
consecutive hours, 0 Gas Flowrate automatically
open the emergency system valve. Opening
function is show with flashing Led "ALARM
Emergency system ON"
•
Third switch is used to define the presence of the Gas
Compressor Unit (GCU) which is an external device
used to generate Storage Hi Pressure.
3= OFF GCU not present
3= ON GCU Present – Dosaodor-D generate command
for control GCU function
•
Fourth switch is used to define the presence of the
Communication Modem on COM1
4= OFF MODEM not present
4= ON
MODEM Present – Dosaodor-D configure Modem
in accordance with Modem Type programmed in Loc. 09
•
Mount back the metal protection on the signal
acquisition card.
Check all of the electrical and pneumatic connections for
proper conformity throughout the entire system, using the
diagrams and drawings as specified.
Check that all valves for connection between the pneumatic
panel and remaining part of the station are perfectly closed
as it is only possible to proceed with switching on the control
unit only under these conditions.
Control Unit Power‑on
If all of the preliminary checks described in the preceding
section have been carried out, the system can be switched on.
Set the key switch to PROG-ON.
Raise the magnetic thermal switch, which is located next to
the electronic control unit, while keeping the Alarm Reset
key pressed. This procedure switches on the control unit
and perform a complete reset on the memory.
WARNING
!
The control unit is normally configured to
operate at 230 V 50 Hz voltage. In case the
system needs a 150 V voltage supply, the
position of the selection jumper located
inside the power supply, placed on the back
of the cabin, must be modified.
If the preliminary steps described above have been strictly
followed, these indicators will switch on:
•
Indicator - DISABLED
•
Indicator - INJECTOR 1
•
Indicator - ALARM - EMERGENCY SYSTEM ON
•
Indicator – AC LINE
