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 separator (No. 10) and
the value indicated on the pressure gauge
(No. 19) is stable at the predetermined value (recommended value: 0.2 to
0.4 MPaG.)
(2) 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, (3) is the next step.
(3) 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.
(4) Starting operation
When the water reaches or exceeds the set
flow rate
1)
, the flow sensor (No. 7) turns ON
to start the operation after the standby time of
5 seconds
2) 3)
. (The LED lamp of the flow
amplifier in the control panel lights up in
yellow or green.)
The motorized valve (No. 12) opens and the
control valve (No. 11) 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.
(5) Water temperature:
The difference between the target temperature and the water temperature
is normally
1
C, depending on the operating conditions.
When the temperature difference is 3
C or more, or when the water
temperature fluctuates, it is likely that the water flow rate is also fluctuating
greatly or is below/around the controllable flow rate. In such cases, contact
the facility manager.
