Master Minimum

Selecting this menu item will display the status of the minimum flow alarm. The normal

status of this flag is off. It may be toggled on or off by using the Up and Down arrow

keys. If this flag displays ON, there has been a minimum flow alarm. Correct the problem

and set the flag to OFF. The minimum flow is necessary when the pump station requires

a minimum flow for cooling purposes. This alarm will turn off the master output to save

the pump from damage. The programs will continue to run. This alarm is operated by the

central system.

Unexpected Flow

Selecting this menu item will display the status of the unexpected flow alarm. The normal

status of this flag is off. It may be toggled to on or off by using the Up and Down arrow

keys. If this flag displays ON, there has been an unexpected flow condition. Correct the

problem if necessary and set the flag to OFF. This flag is set when the controller detects

flow while no station is running in the field controller.

Over Flows

Selecting this menu item will display the flow alarm status of the individual stations.

There must be a flow meter installed at the data retrieval port on the controller for this

feature function. If flow values have been properly set, the controller will watch the flow

as programs run. If there is a problem with a station such as broken line, broken heads,

etc., the controller will set the alarm for that station. If there are numerous stations

running at any one time and there is a flow problem with one station, the controller will

shut down the stations one at a time and check flow. This process will continue until the

malfunctioning station or stations are detected and disabled. Other stations that were

running will return to normal operation one at a time.

Use the Up and Down arrow keys to step through the stations and view or edit the ON or

OFF status of the flow alarms. The normal status is OFF. If the alarm status of a station is

ON, the station will not run in automatic mode.
