5.3.10 Submenu “Opt. Outputs Settings”

Two sets of optically-isolated digital outputs are provided to actuate user-sup-
plied equipment. These are programmable via digital interface or LCD/Keypad
such that the outputs can be made to switch when a specified event occurs (e.g.
when a Low or High Flow Alarm limit is exceeded, when the Totalizer reaches a
specified value), or it may be directly controlled by user.

The user can configure each optical output action from 9 different options:

• Disabled: No Action.

(Output is not assigned to any events and is not energized).

• Low Flow Alarm.
• High Flow Alarm.
• Range between H&L Flow Alarm settings.
• Totalizer #1 reading exceed set limit.
• Totalizer #2 reading exceed set limit.
• Pulse Output function.
• Diagnostic: Output will be energized when any of the Diagnostic or

System events are active.

• Manual On Control: Output will be energized until Disabled option is

selected.

By default both optically-isolated outputs are disabled.

NOTE: Optically-isolated outputs are accessible via screw terminal
header J1 and require application of external DC voltage across
terminals. See Paragraph 4.5 for proper wiring connections.
