3.4 Connections to the relay outputs Warning
If external electrical circuits that are subject to the danger of
physical contact are incorrectly connected to the relay contacts,
there may be a danger of life threaten ing electric shock. Elec trical
circuits are regarded to be subject to the danger of physical
contact when there are voltages higher than the Safety Extra Low
Voltage (SELV).
Pay attention to the following points during installation:
Electrical circuits subject to the danger of physic al contact
must only be connected by a qualified electrician.
Electrical circuits subject to the danger of physic al contact
must only be connected when they are voltage-free.
The terminal strip of the MIQ/R6 output module has two
segments for relay outputs with three relay connections each
(R1-R3 and R4-R6).
If electrical circuits subject to the danger of physical contact
are switched with a relay, no circuit that is not subject to this
danger (e. g. the MIQ/CHV module) may be operated in the
same output segment of the MIQ/R6. For such applications use
the second output segment of the MIQ/R6.
Switching voltages and switching currents on the relay
contacts must not exceed the values specified in chapter 6
T
ECHNICAL DATA. Protect electrical cir cuits against currents that
are too high with an electrical fuse.
Only single-phase consumers can be switched with the relays.
Under no circumstances must multiphase consumers be
switched with the aid of several relays (example three-phase
current driven pumps). Always switch multiphase consumers
via a protective relay.
The MIQ/R6 may only be opened after the installation if all
external voltages have been previously switched off.

4 Settings
The MIQ/R6 module has six relay outputs.
Relay outputs operate as openers (normally closed) or closers
(normally open).
On the terminal, you can:
assign a name to the outputs (see section 4.2).
link outputs with sensors (see section 4.3)
delete links of outputs with sensors (see section 4.4)
adjust outputs (see section 4.5)
check the condition of the outputs (see section 4.6)
Basic information on how to use relay outputs is given in section 4.1.
Note
The general operating principles are given in the system operating
manual or in the component operating manual of the terminal
components.

4.1 Basic information on relay functions
In this chapter, you will find general basic information concerning the
following relay functions:
Monitoring (see section 4.1.1)
Limit indicator (see section 4.1.2)
Proportional output (see section 4.1.3)
4.1.1 Event monitoring
When using a relay for monitor ing, a relay action (Open, Close) occurs
when certain states occur. This function is suitable, e.g. for the
monitoring of errors in the system.
Note
For monitoring functions, use the relay preferably as an opener
(normally closed, see section 4.5.1). In the case of an error, the relay
opens. As a result, the monitoring function operates even if, e.g. the
supply voltage fails.
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 4-3).
Monitoring two limiting values using two relays:
If the upper limiting valu e is exceeded or undercut , a relay switc hes,
and if the lower limiting value is exceeded or undercut, anoth er relay
switches. The Open or Close relay actions are possi ble in each case
(see page 4-3).
Note
If the simple monitoring function (Open, Close) with one or two relays
is not sufficient, use proportional output (see section 4.1.3).

A switching delay (t) can be set up for each relay for switching
processes. This is the time period for which a limiting value must be
exceeded before the relay switches. This prevents f requent switching if
the measured values are close to the limiting value.

4.1.3 Proportional output
In the case of proportional output, a relay switches cycli cally on and off
in a defined measured value range (proportional range). At the same
time, the relay switches with a:
duration of operation that corresponds to the measured value
(pulse-width output, see page 4-6) or
switching frequency (frequency output, see page 4-7).
Proportional outputs can be used in the following way:
Output with one relay:
An output range is defined with a Start value and an End value. No
output takes place above and below the output range (see page 4-
5).
Output with two relays :
An output range is defined for each relay with a St art value and an
End val ue. One relay outputs in the upper output range and a further
relay in the lower output range (see page 4-5).

Pulse width output The output of the pulse width is used, e.g. for controlling valves.
Pulse-width regulation changes the duration of operation (t
) of the
on
output signal. Depending on the posi ti on of the measured value in the
proportional range, the relay is operated for a longer or shorter time
period.

Frequency output Switching frequency out put is used, e.g. for controlling dosing pumps.
In contrast to the pulse-width output, not the pulse width is modulated
with frequency output but the switchi ng frequency of t he out put si gnal.
Depending on the position of the measured value in the proportional
range, the relay is switched more often or less often.
Fig. 4-5 Relay output of frequency output
While the selected switching duration (ton = 0.3 s) always remains
constant, the switching frequency at which the rel ay switches changes
depending on the measured value.
If the measured value is at the end of the proportional range (End
value), the switching frequency is higher.
If the measured value is at the beginning of the proportional range
(Start value ), the switching frequency is low.

4.5.7 Cleaning
Note
When using the MIQ/CHV PLUS valve module, it is best to set the Cleaning function directly at the valve output (V) of the MIQ/CHV PLUS (see operating manual of the MIQ/CHV PLUS). The relay can then be used for other purposes.
Function The Cleaning function enabl es the time controlled automatic start of t he
sensor cleaning function with the aid of a relay of the MIQ/R6.
The relay controls the MIQ/CHV (PLUS) valve modul e and switches on
or off the compressed air for the CH sensor cleaning head.
In order to set up the Cleaning function for a relay output, the relay
output must be linked with a sensor (see section 4.3).
The relay assigned to the MIQ/R6 compon ent always works as a closer
relay.
Testing the
operativeness
The cleaning cycle consists of Cleaning durati on and Adjustment time.
During the cleaning cycle the Clean display flashes. The output s linked
with this sensor are frozen. The maintenance condition (see
section 4.8) is active.
After the Cleaning duration, the relay is opened. During the following
Adjustment time the outputs remain blocked.
The outputs linked with this sensor are only released when the cleaning
cycle is completed. The Clean display disappears. The maintenance
condition is finished.
You can test the operativeness of the cleaning system as follows:
manually open or close the relay with the Manual contr ol f unctio n ( see
section 4.5.9) and, while doing so, check the behavior of the cleaning
system.
Alternatively, you can test the operati veness of the cl eaning system by
checking the performance of the function at the start time set up
(reference time ± interval). To perfor m a tes t immediat ely, yo u can set
the reference time so that the next cleaning will start in a few minutes

Independent of the specified behav ior at error, the followi ng conditions
lead to the freezing of the output states:
The linked sensor is in the maintenance condition
(display of Cal, Clean, or a flashing measured value).
Communication of the MIQ/R6 with t he IQ S
ENSOR NET controller is
disturbed for a short time. After the malfunction has lasted for
