3. Starting commissioning
(1) Valve operation:
Open the steam inlet valve (No. 9) as
slowly as possible.
Make sure that condensate is discharged
from the condensate outlet of the steam
control valve with the condensate
separator (No. 10) and the value
indicated on the pressure gauge (No. 19)
is stable at the predetermined value
(recommended value: 0.3 to 0.6 MPaG.)
(2) Setting supply pressure of the
PowerTrap:
Adjust the pressure supplied to the
PowerTrap by turning the handle of the
pressure reducing valve (No. 15) so that
the pressure gauge (No. 20) indicates the
pressure specified in the 'product specification document'. After the
pressure is set, fix the handle with the locknut located below it.
(3) Stand-by operation (STARTING UP…)
a)
Touch the START button on the display.
b)
Even if the START button is touched, steam
will not flow unless water is flowing.
If water is already flowing at a temperature
above the set temperature, (4) is the next step.
(4) Valve operation for the water supply system
Open the valve (not included with the unit) on the water supply system.
If the valve is in a remote location, one person should operate the valve
and one person should remain by the unit for observation.
(5) Starting operation
When the water reaches or exceeds the set
flow rate
1)
, the flow sensor (No. 7) turns ON
(the touch panel displays the water flow in the
unit) to start the operation after the standby
time of 5 seconds
2) 3)
.
The solenoid valve (No. 11) opens and the
steam control valve with condensate separator
(No. 10) adjusts the steam flow rate.
The time required for the water to reach the
set temperature is approximately 1 to 4 minutes, depending on the
operating conditions.
1)
The set flow rate of water is the minimum controllable flow rate for the unit under
operating conditions. (Factory setting: see 'product specification document'.)
2)
Alarm delay time is the time required to reach stable flow after water begins to
flow, or the time required for the cooling circulation unit to operate to prevent
overheating when the water flow stops. (Factory setting: 5 seconds).
3)
If the water flow rate does not stabilize within 5 seconds and the unit repeatedly
starts and stops operation, the alarm delay time must be changed. Consult TLV
on how to change settings.
