Bullet Item Description
4 Units of Measure
Choices are PSI, BAR and MPA. Pressures will be displayed in
the units shown in this area.
5 GAS Type
Displays the gas type the IntelliSwitch is controlling. This is set
by the user from the EDIT screen.
6 Reserve Supply Status
If the product is equipped with a Reserve Gas Source the status
of that source will be displayed here. Green In-Use indicates
that the IntelliSwitch is using this source. A Red Fault indicates
that the reserve supply is low on gas and needs to be replaced.
It is possible to have the Reserve in-use and have a fault. This
would occur if both the left and right inlets are also in replace.
7 Switchover Pressure
This is a preset pressure in the IntelliSwitch used to determine
when an inlet can no longer provide enough gas pressure to the
delivery regulator. This value can be changed in the EDIT
screen.
8 Hysteresis
This is a preset pressure value that is used to prevent the
IntelliSwitch from “dithering” at the switchover point.
9 Look Back
This is a preset time in minutes used for liquid cylinders to
determine when to look back at an inlet pressure to determine if
pressure has been restored above the switchover point. The
IntelliSwitch will look back at an inlet after the look back time has
expired to see if its pressure has built back up above the
switchover point. If it has, then the IntelliSwitch will switch back
to that side to try to use more of the gas.
10 Switch back
A preset time in minutes used for liquid cylinders in conjunction
with the look back time. If the look back feature is invoked and
after time out has determine that it can switch back to a side
whose pressure has built back, a switch back timer will start. If
the inlet pressure on the same side drops again before the
switchback time has expired the IntelliSwitch determines that
that side is truly empty and will alarm and switch to the other
inlet.
11 Delivery Pressure Tolerance
This is the variation in delivery regulator pressure that is allowed
before the IntelliSwitch switches regulators and alarms. The
value is +/- the pressure shown.
12
Delivery Regulator Alarm
Delay
This is the amount of time, in seconds, that the IntelliSwitch will
wait before switching delivery regulators or alarming. This
prevents false switching and alarming if the delivery regulator
pressure should increase or decrease from its nominal value
beyond the delivery regulator tolerance for a very brief time.
13 Version
this is the software version of the IntelliSwitch software on your
system
14 System ID
This is a number that can be assigned by the user to identify the
IntelliSwitch.
15 REFRESH button
Clicking on this button will force an immediate display update.
Normally the IWS updates the display approximately every 4-5
minutes unless an “event” occurs. An “event” is defined as an
alarm or any activity such as pressing a button that causes
switching or a change in cylinder selection
16 EVENT LOG This is a location used to list any events that may occur
17 CLEAR button This button clears the contents of the event log
18 PRINT button
This button allows the printing of the contents of the event log to
a users computer
19 EDIT button
Clicking this button will bring the user to the EDIT screen where
changes to parameters can be made. The EDIT screen is
password protected
