MIQ/CR3; DIQ/CR3 Settings 4 Settings The combi output module has three relays outputs and three current outputs. Relay outputs operate as openers or closers. Current outputs provide a current that depends on the measured value. On the terminal or Universal Transmitter, you can assign names to the outputs (with the 2020 XT system only, 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.
Settings MIQ/CR3; DIQ/CR3 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 monitoring, a relay action (Open, Close) occurs when certain states occur. This function is suitable, e.g. for the monitoring of errors in the system.
MIQ/CR3; DIQ/CR3 Settings 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).

MIQ/CR3; DIQ/CR3 Settings 4.1.3 Proportional output In the case of proportional output, a relay switches cyclically 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 4-7) or switching frequency (frequency output, see page 4-8).

MIQ/CR3; DIQ/CR3 Pulse width output Settings The output of the pulse width is used, e.g. for controlling valves. Pulse-width regulation changes the duration of operation (ton) of the output signal. Depending on the position of the measured value in the proportional range, the relay is operated for a longer or shorter time period. Relay tOn t Off On Off T Fig.
Settings Frequency output MIQ/CR3; DIQ/CR3 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 but the switching frequency of the output signal. Depending on the position of the measured value in the proportional range, the relay is switched more often or less often. Relay tOn = 0.3 s On Off T Fig.
