3.4 Connections to the relay and current 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 physical contact
must only be connected by a qualified electrician.
Electrical circuits subject to the danger of physical contact
must only be connected when they are voltage-free.
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 module. Use an additional output module for such applications.
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.
After the output module has been installed, it may only be
opened if all external voltages have been switched off beforehand.

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 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 (see section 4.5.1). In the cas e of an err or, t he r elay ope ns. As a res ult, 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 speci fied 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 o r l ower 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 v alue is exceeded or unde rcut, a relay swi tches, and if the lower limiting value is exceeded or undercut, anothe r relay switches. The Open or Close rel ay 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).

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

4.1.3 Proportional output

In the case of proporti onal output, a relay switc hes cyclic ally on and of f 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 4-7) or
switching frequency (frequency output , see page 4-8).
Proportional outputs can be used in the following way: Output with one relay:
An output range is defi ned with a Start value and an End value. No output takes place above and below the output range (see page 4-6).
Output with two relays:
An output range is defined for each relay with a Start value and an End value. One relay outputs in the up per output range and a further relay in the lower output range (see page 4-6).

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

This means the relay operates for a longer period.
If the measured value is at the beginning of the proportional range
(Start value ), the turn-on duration (t

Frequency output Switching frequency output is used, e.g. for controlling dosing pumps.
In contrast to the pulse-width output, not the pulse width is modulated with frequency output b ut the swi tching frequency of the out put signal . Depending on the position of the measured value in the proportional range, the relay is switched more often or le ss 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 whic h the relay 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.

Characteristic curves Through the select ion of the Start value and En d valu e, the proportional
output can be operated with a p ositive or negative char acteristic curve. Positive cha r a cteristic curv e :
Select the End value to be greater than the Start value. The turn-on duration or frequency increases wit h an increasing measured value (see page 4-10).
Negative characteristic curve:
Select the End value to be smaller than the St art value. The turn-on duration or frequency decreases with an increasing measured value (see page 4-11).
The maximum values for the pulse width or switching frequency are assigned to the End value and the minimum values f or turn-on duration or frequency are assigned to the Start value.

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 f unction enables the time controlled automatic sta rt of the
sensor cleaning function with the aid of a relay of the combi output module. The relay controls the MIQ/CHV valve module 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).
Testing the
operativeness
The relay assigned to the combi output module always works as a closer.
The cleaning cycle consists of Cleaning dura tion and Adjustment time. During the cleaning cycle the Clean display f lashes. The outputs linked
with this sensor are frozen. The maintenance condition (see section 4.9) is active.
After the Cleaning duration, the relay i s opened. During the following Adjustment time the outputs remain blocked. The outputs linked with this sensor are only releas ed 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 unction (see section 4.5.9) and, while doing so, check the behavior of the clea ning system.
Alternatively, you can test the operativeness of the cleaning system by checking the performance of the function at the start time set up (reference time ± interval). To perfor m a test immediat ely , you can set the reference time so that the next cleaning will start in a few minutes (settings: see following table) .

The next cleaning cycle will be performed at the time set up.
Note
In case of a power failure, all relays open. The cleaning cycle is canceled. The outputs linked with the sensor change to the non-act ive condition (see section 4.8.2). As soon as the power is available, the outputs are released again. The next cleaning cycle will be perform ed at the time set up.

4.7 Checking the status of the outputs

This function offers a simple overview of the states of all outputs of the combi output module.
For relays, the status open or closed is displayed. For current outputs, the current value available at the output is
displayed. With the System 182 XT, you can recall the states of the outputs via the
measured value and status display (see system operati ng manual of the DIQ/S 182 XT).
With the 2020 XT system, the function, 394 - Status of outpu t channels, in the menu, Settings/Service/List of all components can be accessed as follows:
1 Call up the measured value display with m. 2 Open the Settings menu with 3 Highlight t he Service menu item wit h d and confirm wit h g.

4.8 Behavior of linked outputs

4.8.1 Behavior in case of error

For linked relay outputs or current outputs, you can determine the behavior of the outputs in case of errors.
Depending on the use of the output, the beha vior in case of errors is set in the following menus:
Output menu
Frequency controller Frequency with error (see section 4.5.5) Pulse-width contr. Error pulse width (see section 4.5.6) Recorder Current with error (see section 4.6.1)
Error events The defined behavior occurs in the case of the following events or
Freezing the states of
the outputs
Resumption of the
normal function
conditions: The linked sensor does not supply a valid measured value
(display of Init, Error, "-----", or OFL)
Communication of the MIQ/CR3; DIQ/CR3 with the I Q SENSOR NET
controller is disturbed fo r longer than 2 minutes.
The supply voltage for the MIQ/CR3; DIQ/CR3 is too low.In the Recorder functi on, the measured value of the li nked sensor is
outside the range between Start value and End value.
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/CR3; DIQ/CR3 with the I Q S
ENSOR NET
controller is disturbed for a short time. After the malfunction has lasted for 2 minutes the output changes to the specified behavior in the case of an error.
The relay output or current output automatically returns to its normal state as soon as all error conditions are over and all conditions causing a freezing of outputs are cleared.

4.8.2 Behavior in non-operative condition

An output is non-operative when no functi on is activated for the out put. An output becomes non-operative in case of Power failure
(As soon as the supply voltage is sufficie nt again, the non-operati ve condition of the outputs ends. The outputs function as speci fied by the user again.)

4.9 Maintenance condition of sensors

The maintenance condition of sensors serves to calibrate, clean, service and repair (remove and replace) sensors.
In the maintenance condition the system does not react to the current measured value or the
condition of the selected sensor
linked outputs are frozensensor errors do not prompt changes in the conditions of linked
outputs.
The maintenance condition is automatically activat ed during calibration. After calibration the sensor remains in the
maintenance condition until the maintenance condition is switched off manually (see section 4.9.2)
during the cleaning cycle (see section 4.5.7) Switch on the maintenance condition manually when you want to clean,
service or repair (remove and replace) a sensor (see section 4.9.1). When you have finished cleaning, servicing or repairing the sensor,
switch off the maintenance condition manuall y (see section 4.9.2).
Note
When a sensor is in the maintenance condition, the measured values or status indications of the sensor in th e measured valu e display fl ash.
