ViewSmart 200/2050/2150 Controller User's Manual

Document: UM-1021

Revision Level B



Low Trip

is set for

for increasing alarms or

YES

for decreasing alarms to

determine if the alarm activates upon exceeding or falling below the set-point.



Latching

determines either manual or automatic alarm reset operation.

YES

requires a manual

Alarm Reset

to unlatch the alarm even though an alarm condition

no longer exists.

YES

also causes this alarm’s common relay, front panel LED, and

optional discrete relay to latch.

allows all outputs for this alarm to automatically

reset after the alarm condition clears.

Discrete LED indicators on the front panel indicate the status of each alarm. Any

new

alarm event causes the associated LED to flash until an

Alarm Reset

occurs causing an

acknowledged

steady on condition. Operators should recognize

new

alarms by a flashing

LED.

Alarm Reset

also

acknowledges

, or deactivates, audible devices driven by the

AUDIBLE ALARM option connector J2 (see Figure 3.1)

2.2.4

CONFIGURE MENU TO DEFINE CHANNEL

The channel setup menu after the alarm menus is

CONFIGURE.

It allows setting

Name

and

EUNIT

ASCII fields, defining the measurement range, and how many decimal points

of resolution the reading will have.

Figure 2.5

2.2.4a NAME / EUNITS ASCII DATA FIELDS

The first two items in this menu are for entering the 10 character channel

Name

and

engineering unit

ASCII fields.

Name

should describe the channel’s data in user

terminology such as tag # or other description.

Eunits

should define the units of measure

for what this channel is to display. Several standard

Eunits

fields are available by

pressing

EDIT

but if these are inappropriate, a CUSTOM field allows editing of each

character. Section 2.2 describes how to modify these fields using the keypad.

2.2.4b INPUT MEASUREMENT RANGE

The

ZERO / SPAN

menu entries allow configuration of the measurement range

displayed by this channel. Measurement Range defines the range of the input signal’s
engineering units. For example, if a channel’s input is 4-20mA from a transmitter
