2-Setting Up the

Controller Area

Dual Flow %

You can set the tolerance between the flow switch monitor and the flow readings for

injection applications before the flow switch alarm activates due to out of tolerance

conditions.

Out of tolerance conditions must be met for at least five seconds before the alarms are

activated.

For Gran 3 applications, set the tolerances between the dual encoder readings before

the ‘Dual Flow’ alarm is enabled. The out of tolerance condition must be met for 5

seconds before the alarm occurs.

Off Rate %

You can set the Off Rate Percent alarm to activate when the actual application rate

differs from the application target rate for more than five seconds.

Low Tank

You can set the Low Tank alarm to activate when the tank falls below a designated

level. The alarm shuts off when either the booms are turned off or when you enter a

new value that is equal to or less than the current Tank Volume. If you enter a value of

zero in the field, the alarm is disabled.

Low Limit

You can set the Low Limit alarm to activate when the actual volume per minute rate

falls below the target rate. When the volume falls below the low limit rate, the control

valve stops closing and the alarm displays. This value automatically proportions to the

percentage of the booms that are in the ‘On’ position. For example, if this value is set

to four and half of the total boom length is on, Viper automatically sets the valve to two.
