4.1.2 Limit indicator

With a limit indicator, a relay switches when a specified limiting value is

exceeded or undercut.

Limit indicators can be used in the following way:

 Monitoring a limiting value using a relay:

when a limiting value (upper or lower limiting value) is exceeded or

undercut, a relay switches. The Open or Close relay actions are

possible in each case (see page 4-4).

 Monitoring two limiting values using two relays:

If the upper limiting value is exceeded or undercut, a relay switches,

and if the lower limiting value is exceeded or undercut, another relay

switches. The Open or Close relay actions are possible in each case

(see page 4-4).

Note

If the simple monitoring function (Open, Close) with one or two relays

is not sufficient, use proportional output (see section 4.1.3).
