4.8 Submenu Optical Outputs Numerical entry

Two sets of optically isolated outputs are provided to actuate user supplied equip-
ment. These are programmable via digital interface or optional 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 or when the totalizer reaches a speci-
fied value) or may be directly controlled by user.

The user can configure each optical output action from 11 different options:

- Disabled: No Action (output is not assigned to any events and not energized)
- Low Flow Alarm
- High Flow Alarm
- Range between H&L Flow alarm settings
- Main Totalizer reading exceed set limit
- Pilot Totalizer reading exceed set limit
- Low Temperature alarm (*RTD option only)
- High Temperature alarm (*RTD option only)
- Range between High and Low Temperature alarm (*RTD option only)
- Diagnostic: Output will be energized when any of the Diagnostic events are active
- Manual On Control: Output will be energized until Disabled option will be

selected.

A typical display with Optical Output Function selection is shown below.

The listed above Optical Output selections can be set with the Up and Dn buttons
and are accepted by pressing ENT button.
