MOUNTING
Installation with channel selector:
or
EARTH TERMINAL (for grounding interferences)
If outside interferences voltage act on the instrument, functional troubles may be
caused (concerns also high-frequency interferences). For grounding interferences
and ensuring the electromagnetic immunity, an earth must be connected: Terminal 6,
20 and 21 must be connected to earth potential by means of a short cable
(approx.20cm,e.g. to switch cabinet ground). Keep this cable separate from mains
cables.

The Digital 380 indicator is provided for installation in an enclosure. The electrical
safety is reached by correct installation in a control cabinet/panel.
ELECTRICAL CONNECTIONS
Keep mains cables separate from signal and measuring cables. We recommend
twisted and sceened measurung cables (screen connected to earth).
This ensures optimum interference suppression!
Connected final elements must be equipped with protective circuits to manufacturer
specification. This avoids voltage peaks which can cause trouble to the instrument.
The instruments must be protected by an individual or common fuse for a max.
power consumption of 8VA per unit (standard fuse ratings, min 1 A)!.
aSignal and measurement circuits may carry max. 50 V r.m.s. against
ground,mains circuits may carry max. 250 V r.m.s. between terminals

If e.g. a controller is connected in the same measurement loop, even
minimum pulses during channel selecting might cause controller reactions
due to the D action.
Therefore, external shunts (50 [) and voltage input U_3 (0,2...1V instead of
4...20 mA/0...1V instead of 0...20 mA) should be used. For connection, see

This function can linearize any input signal via 16
adjustable segments. (With the CS connected, this
setting is identical for all channels but can be
activated individually for each channel.)

segments.

One of seven mathematic functions can be selected. This function block
operates with the output value of function 1, or with display range w0/w100
selected in menu Input, if no mathematic function 1 was selected.
Unlike function 1, this function has a control input. Selection where the
control signal of mathematic function 2 comes from can be done in menu
Ctrl .
When actuating the selected control input (ÄCtrl), the instantaneous
input value is used as new zero.

With a constant input value, the integrator output reaches this
value after elapse of the adjusted time constant t!
Example: A flow is measured in m3/h. The integrator shall measure the flow
total. As the measured flow is referred to time unit hours, the time constant
must also be 1 hour = 60 minutes. Parameter P1 can be used for zero
correction.
In the manual scanner mode, using the integrator is little purposeful, since a
channel is only used for calculation, if it happened to be selected. In the
automatic scanner mode, the scanning interval during which other channels
are measured is taken into account in the calculation.
However, input changes during this time are not measured, since the
channel is not measured!

When using a Digital 380 channel selector in the automatic scan mode
(SC_on), the built-in relays are used for common alarm signalling, i.e. the
corresponding relay switches with at least one alarm in the measured
channels.
In this case, the mode (normally open or normally closed) is dependent of
the channel 1 setting.

ERDANSCHLUSS (zum Ableiten von Ströreinflüssen)
Wenn von außen Störspannungen( auch hochfrequente) auf das Gerät einwirken, so
kann dies zu Funktionsstörungen führen. Um Störungen abzuleiten und die
Störfestigkeit sicherzustellen, muß eine Erde angeschlossen werden:Die
Anschlüsse 6, 20 und 21(sind intern nicht verbunden!) müssen mit einer kurzen
Leitung mit Erdpotential verbunden werden (ca. 20cm, z.B.an Schaltschrankmasse)!
Diese Leitung ist getrennt von Netzleitungen zu verlegen.
