Operation

Off Ratio Time to Fault Entry

The VRM and VPM system now allows the user to enter
the Off Ratio Time to Fault duration, rather than having
the system automatically set this value based o the flow
rate selected. This duration dictates the amount of time
the system should allow an off ratio condition, before off
ratio deviation or alarm should be generated. This fea-
ture is password protected.
To access this feature, the user needs to navigate to the
"Off Ratio Fault Password" field as illustrated above on
the System #3 setup screen, then enter the password
indicated below:
After the correct password is entered, the "Off Ratio
Fault Time Override" option will become available for
editing, as indicated below:

The user can now navigate to this field, enter any num-
ber from 0 (default value, indicating the override feature
if off) to 30 seconds. If the "Off Ratio Fault Time Over-
ride" control is to be disabled again, simply enter num-
ber into other password field a value which is NOT the
correct password (as indicated below), and the control
will become disabled (hidden) again.
