Frequently Asked Questions - DT0001 IFM

How to connect the DT0001 relay?

Use the 16 terminals to connect the power supply (230 V AC or 24 V DC), the input signal (PNP sensor or mechanical contact), and the changeover output. Refer to the wiring diagram on the enclosure or in the manual.

How to adjust the on-delay timing?

Set the AV selector switch (on-delay) to the desired time range (I, II, III or IV). Then adjust the corresponding potentiometer (3) to set the precise time between 10% and 100% of the range.

The LEDs do not light up, what to do?

Check the power supply voltage (230 V AC or 24 V DC) and the wiring. If the green 'Netz' LED does not light up, the device is not powered. Also check external fuses.

How to use a pulse on energization?

Set switch (5) to position 'F' (pulse on energization). The pulse duration is adjusted via the off-delay potentiometer (4). The time t1 can be adjusted with potentiometer (3) to delay the start of the pulse.

What is the minimum duration of the input signal?

The input signal must last at least 300 ms to be detected correctly. For pulse on energization, the minimum t1 time is approximately 250 ms.

Can I use an NPN sensor?

No, the input is designed for PNP signals (high level > 15 V, ≥ 7 mA) or mechanical contacts. For an NPN sensor, use an adapter or an intermediate relay.

How to choose the timing range?

Select the range suitable for your application:
- I: 0.25…2.50 s
- II: 1…10 s
- III: 8…80 s
- IV: 64…640 s
Use the AV (on-delay) and RV (off-delay) switches.

What does the yellow 'Signal' indicator mean?

The yellow LED indicates the presence of a valid input signal. If it does not light up while a sensor is active, check the wiring and polarity.

The relay does not switch despite the signal, why?

Check the timing settings: if they are too long, the output will take time to change. Make sure the function switch (5) is in position 'V' (timing) or 'F'/'R' (pulse). Also check the power supply voltage and the state of the output.

How to clean the relay?

Disconnect the power supply. Use a dry, lint-free cloth to clean the enclosure. Do not use solvents or abrasive products.

USER MANUAL DT0001 IFM

Function and features

The multifunction relay T 700 is a time-controlled switching amplifier for pnp-switching sensors and speed monitors, but it can also be triggered by mechanical contacts or push Buttons.

The switching of the output relay depending on the input signal can be influenced via timers with different functions.

Functions

The output relay switches:

ON delay
OFF delay
ON and OFF delay
ON pulse
OFF pulse
- delayed ON pulse
- delayed OFF pulse

The functions ON delay and OFF delay are active all the time. If one function is not needed it must be set to the lowest value (approx. 250 ms).

Please note

If the T 700 in function "OFF pulse" is connected to the operating voltage this causes a fleeting pulse of the output relay.

Time ranges

There is one time range available for the ON delay and one for the OFF delay. The entire time ranges of 0.25 to 640 seconds are divided into four individual ranges which can be set with a switch.

Position Time range switch (t1/t2) [seconds]
I 0,25...2,50
II 1...10
III 8...80
IV 64...640

Setting of the time

After preselection of the time range the time is set with the corresponding pot. This scale is divided by percentage of the time range end value (10...100%).

Pot (t1/t2) Time [%] [approx.	seconds]
