5.1 Explanation of Main Controller Screens
1.
Operation Screen:
This screen displays a live reading of the pressure chamber operating
conditions. These parameters include: gas temperature, gas pressure and superheat.
2.
Water Temperature:
This screen displays a live reading of the water tank temperature. This is
the temperature reading that is used for PID control of the water temperature and all appropriate
water temperature alarms.
3.
NOT USED in Model VPH-10000-1.
4.
Heater Power:
This screen displays the instantaneous heater power/energy output. The value
displayed is based on the 4-20 mA control signal sent to the heater control box. This provides the
current energy consumption and provides some indication that chamber/heater cleaning is required
due to irregularly high consumption.
5.
Solenoid Override:
This screen displays the current status of the water refi ll solenoid (either open
or closed). From this screen the solenoid can be overridden from normal operation to open (and
fi ll the water tank) by pressing and holding the
key.
6.
Alarm Status:
This screen displays any alarm conditions that may currently be active, or displays
“normal” if no alarm conditions exist. If multiple alarms exist, the controller will cycle all
active alarms on this screen every two seconds. For more information on alarm conditions and
preventative actions refer to Sections III.7 and V.
7.
Password Screen:
This screen allows access to all the editable features of the VPH-10000-1.
To access the confi guration screens the correct password must be entered on this screen. The
password for the VPH-10000-1 is “100” and can be entered using the
and
keys. Once the
correct password is blinking the user may press the
key to access the remaining screens.
8.
Vaporizer Units:
This screen allows the user to adjust the operating units used. Temperature
values can be displayed in either degrees Fahrenheit (F) or in degrees Celsius (C). Pressure values
can be displayed in either psig (psi) or barg (bar). To change units, press the
or
key until the
appropriate parameter is blinking, then press the
key.
9.
Water Temperature Alarm:
This screen allows the user to adjust the high and low water
temperature alarm settings. Due to inherent safety and design features the adjustable range of the
low water temperature alarm has been set to 160 – 170˚F (71 – 77˚C) and the adjustable range of
the high water temperature alarm has been set to 195 – 205˚F (91 – 96˚C). To change values, press
the
or
key until the appropriate parameter is blinking, then press the
key to increase or the
key to decrease.
10.
Gas Pressure Alarm:
This screen allows the user to adjust the pressure value above which the gas
pressure alarm will activate. This setting has an adjustable range of 250 – 300 psi (17 – 21 bar).
To edit this value, press the
and
keys when this value is blinking until the appropriate value
is achieved.
11.
Super Heat Alarm Temperature:
This screen allows the user to adjust the minimum allowable
superheat temperature, below which the alarm and all relevant functions will activate (Section
III.7). This value is adjustable from 0 – 50˚F (0 – 27˚C) with “0” disabling the alarm. To edit this
value, press the
and
keys when this value is blinking until the appropriate value is achieved.
Recommended superheat alarm values are: 20ºF for chlorine, 30ºF for sulfur dioxide, and 12ºF for
ammonia.
