Differences between Push button and Switch/Sensor inputs

A push button connected to an input consists of a device, which allows, or not, the current flow while this is being pushed; in normal conditions, push buttons contacts are always open (NO) or closed (NC). This event is a pulsation and the time it lasts, threshold time. Depending on the “Threshold Time” it can be distinguished two different actions:

• Short press
• Long press

A Switch/Sensor connected to an input, consists of an electrical mechanism which may have its contacts open or closed under normal conditions. These mechanisms don’t recover their normal position automatically as with the push button. A transition of a digital signal from low/high/low is called "Edge".

• Falling edge: Closed contact to Open Contact.
• Rising edge: Open contact to Closed Contact.

What type of contacts can be connected on the binary inputs?

Binary inputs of Zennio devices are voltage free contacts. They can be individually configured and each of them can be connected to a push buttons and/or a switch/sensors.

Can I connect several push buttons in parallel in the same input?

Yes, inputs are voltage free, so there is no problem in connecting several push buttons in parallel.

Why do I have to press twice over an input for the output to react?

This is an issue related with the status update of the input. It will be necessary to update the inputs with the status of the corresponding output that is activated by the input. The object of the input should be linked, not only to the group address that activates the output, but also to the group address where the status of that output is sent.

What is the maximum length allowed for the wiring of the digital inputs?

The wiring of the digital inputs can be extended up to 30 meters using a cable with a section between 0.15 mm2 and 1 mm2.

What is the difference between motion detectors P (ZN1IO-DETEC-P) and X (ZN1IO-DETEC-X)?

The only difference is that the motion detector P has a built-in luminosity sensor and it allows to constraint the detection based on the luminosity level detected in the room. The motion detector X has no luminosity sensor.

Can I connect a motion sensor different from DETECT-P/X to an device  input configured as motion sensor?

Zennio devices with inputs configurable as sensor motion have been designed to work together with the motion sensor DETEC-P and DETEC-X

We can’t guarantee the proper working of a different motion sensor connected to a Zennio device input configured as motion sensor, thus, when using a different motion sensor, the input must be configured as binary switch, and the sensor motion must send the detection using a free potential contact.

To which Zennio devices can I connect a motion detector?

Motion detectors can be connected to Zennio devices with analog-digital inputs.

If you do not know if your Zennio device allows the motion detector connection, just look into the device website and you will find that information in the product datasheet.

If the device allows the connection of a motion sensor,  at its website tools section you will find the motion sensor manual.

In the following table you can check all Zennio devices with analog-digital inputs

How can I know the position where the micro switch must be placed (Type A/B)?

Depending on the device where the motion sensor is connected, the micro switch must be placed at the position A or B. To know which position corresponds to your device, it is necessary to check the device datasheet to which the motion sensor will be connected.

 How many sensors can I connect into the same input?

Up to two different sensors can be connected in parallel to the same motion sensor input, as long as at least one of them has the luminosity sensor switch in the OFF position. This is achieved using the micro-switch located on the back of the device. For further information please refer to the motion sensor datasheet.

 Do I need an external power supply for the sensor?

No, you just need to connect it to the inputs of the devices allowing its control

 What is the detection area covered by a Zennio motion sensor?

This feature depends critically on the location of the device. In particular, for a detector located in the ceiling of a room, the detection area can be doubled if you double the height at which it is placed. For further information, consult the motion sensor datasheet.

 How should I install the motion sensor to get the most of its functionality?

In the Motion Sensor area, you can download the Installation Note that includes installation tips to find the most suitable place to be placed.

 How is the luminosity level measured by the sensor sent to the bus? (Only ZN1IO-DETEC-P)

The sensor sends a luminosity level in the range [1.....100] through a 1 byte Communication Objet. In any case this is a a 2 bytes object with the value measured in LUXES.

 Can we cancel the LED blinking everytime there is a detection?

Yes, using the micro switch at the rear of the device.

What is the maximum length allowed for the wiring of the analogue inputs?

The wiring of the analogue inputs can be extended up to 30 meters using a cable with a section between 0.15 mm2 and 1 mm2.

The luminosity sensor does not measure correctly. (Only ZN1IO-DETEC-P)

Check if the microswitch number 2 is placed in the correct position. You can find this information in the data sheet of the device to which it is connected.

To which Zennio devices can I connect a temperature probe?

Temperature probes can be connected to Zennio devices with analog-digital inputs. To know if a device has analog-digital inputs, look into its datasheet.

In the following table you can check all Zennio devices with analog-digital inputs

What is the max cable length of the temperature probes?

The probe cable length provided by Zennio is 1.5 meters, however, this can be enlarged by means of a cable with similar characteristics up to a maximum of 30 meters.

What is the resistance value of the temperature probe at 25°?

The resistance value at 25°C is 6,8 kΩ

What are the valid measurement ranges for the temperature probes?

The following ranges are valid for the probes:

• Epoxi probe: [-30ºC........+90ºC]
• Steel probe: [-30ºC........+125ºC]

What is the appropriate probe in my installation?

It depends on the desired temperature range and the place where the probe will be placed.
As described in the previous question, steel probes have a broader range of measurement and are ready to work in more extreme environments than epoxy probes.

What is the temperature probe precision when it is used in QUAD?

Can I use temperature probes different from the supplied by Zennio?

Zennio devices were designed to operate according to the characteristics of our temperature probes. We can only guarantee the proper working of the device with Zennio probes.

How can I install a temperature probe into a narrow plastic pipe?

Use a T-shaped piece, take advantage of the new outlet to install a thermowell and now you will be able to place inside our steel temperature probe ZN1AC-NTC68S.

How can I hide the ambient temperature probe on the wall?

Install a conventional mounting box and uses a cable outlet cap. Place the temperature probe so that only its measuring end is seen. In this case we recommend using our epoxy resin probes ZN1AC-NTC68E and ZN1AC-NTC68F.
