1 Introduction 1.1 Safety information General information This manual contains information that must be observed in the interest of your own safety and to avoid damage to assets. This information is supported by symbols which are used in this manual as follows. Please read this manual before commissioning the device.

3 Basics 3.1 Radio technology The characteristic framework conditions for each transmission system include the available band width in the electro-magnetic spectrum and the maximum permissible transmission capacity. These parameters define the channel capacity. The main selection criteria for the frequency range to be used include the requirement of a long range, interference resistance as well as the possibility to be able to apply a customized transmission protocol in public spectrum band.
the transmission capacity is only generated for a very short period. Duty cycle in percent identifies the duration of the transmission of a probe related to 1 hour. The entire transmission time can be distributed to several transmission intervals. As such, duty cycle given in percent represents the ratio between transmission time and overall time.
The maximum range between probe and receiver is 300 m in the open air when using the antenna wall holder for the receiver. Ensure visibility between probe and receiver to achieve optimum reception. When installing the receiver into a switch cabinet, behind concrete walls or ceilings, always use the wall holder and antenna cable with the receiver.
3.4 Interferences Collisions when using an excessive number of transmitters When using a large number of probes, do not select a transmission interval which is too low, otherwise the transmission frequency will be unnecessarily obstructed. A too low transmission interval means a very high data volume on the selected frequency which can lead to collisions with other probes.
Page 11
As you can see in figure 5 the error curve jumps up at the number of 24 probes. For this reason, we recommend to use a maximum of 16 probes for the smallest transmission interval of 1 s. For the factory setting 10 s, a considerably larger number of probes is possible. Estimation of the maximum number of transmitters If more than the recommended 16 probes are to be used at a transmission interval of 1 s, select a higher transmission interval to prevent an increased error quota.
Page 12
TIP! In the event of collisions caused by an excessive number of probes, observe and, if necessary, correct the factors "Number of probes", "transmission interval" and on the receiver the "Radio transmission timeout" factor. 12 of 86...

Setup interface The unit is equipped with a setup interface to allow configuration via the setup program. For this purpose, the front features a connector for interface lines with USB/TTL converter for the connection to a PC. The setup interface is factory-set with the following values: Baud rate: 9600 bit/s, Data format: 8 data bits, 1 stop bit, no parity.
Page 16
Depending on the design, the device has a maximum of two relay outputs. The status switching relay output 1 or 2 is determined by different control signals. The desired control signal and the output signal (n/c or n/o contact) for each relay can be set in the parameter level.
4 Installation 4.1 Installation site and climatic conditions 4.1.1 Receiver Installation site and climatic conditions The conditions at the mounting site must meet the requirements specified in the technical data. As far as possible, the installation site should be vibration-free to prevent the screw connections from working loose.

4.3 Receiver installation Fastening the receiver on the top hat rail The receiver is intended for installation on a 35 mm top hat rail according to DIN EN 60 715 TIP! At the installation site, ensure a minimum spacing of 100 mm above the device to allow access to the unlocking slot required for dismantling with a screw driver.
4.4 Fitting the antenna The range between the probe and the receiver is max. 300 m in open air. The antenna used and its correct positioning is a determining factor for both operating distance and reliability of the wireless connection. In practice, the most varied influences affect the wireless transmit distance.
Run input, output and supply cables separately and not in parallel with one another. Sensor and interface cables should be shielded cables with twisted conductors. Do not run cables close to current-carrying components or cables. Ground the shielding on one side. Do not connect any additional loads to the supply terminals of the device.

Chapter 8.2 "Parameter level (PA)" Bottom yellow LED Display Function Yellow Receipt check of each individual radio telegram (data package) briefly received from the probe. The more transmissions received the lighting up higher the flashing speed. 7 Receiver operation At the receiver Operation and configuration of the receiver require four keys located at the front which have various functions depending on the menu.
7.1 Normal display (ND) The normal display is active when the receiver is connected and the voltage supply activated. The measured value of the first transmitter is visible in the top line of the LCD display. The channel designation is visible on the left and the selected unit on the right in the bottom line of the LCD display.
7.3 Display signal quality of the probes received is used to show the signal quality of the current channel in percent in the standard display (NA) (see Figure 21, 100%). The display range between 0 and 100 % is displayed in increments. Steps: (0/20/40/60/80/100) % Display 0:...

This reduces the waiting time until the signal quality display is updated.
Key timeout If no key is pressed in these two levels for a period of 40 s the receiver automatically returns to the standard display (NA). Code interrogation The receiver features one code interrogation each for the change-over to the commissioning/start-up or the parameter level.

8 Configuration of the receiver 8.1 Commissioning/start-up level (In) The receiver channels are assigned to the transmitters in this level (linked with each other). This can be done conveniently via the setup program, or manually via the keyboard. The possibilities are described in the following. Please note the following, independent of the method adopted: Assign each transmitter ID to a transmitter only once, as the receivers •...

Page 39
This way of proceeding is selected when both the transmitters and the receiver are active. Each receiver registers all transmitters received but not linked by itself in a link list allowing a maximum of 25 entries. This list is automatically generated.
8.1.2 Manual assignment of a transmitter ID to a channel This way of proceeding is selected when the receiver is to be prepared prior to putting the transmitters into operation. The transmitter ID (max. 5 digits) can be manually entered for a receiver channel. The function keys of the receiver can be used to assign the individual transmitter to a receiver channel.
To confirm the first digit, press the key. The bottom segments of the second digit from the right are flashing. Repeat steps 3 and 4 until all digits are edited (at least 1 digit, max. 5 digits). Confirm the transmitter ID to be linked with the key.
8.1.5 Configuration of customized transmitter ID's on the transmitter side This method is selected when there are good reasons not to use the factory- provided transmitter ID's. Instead of the factory transmitter ID's, the transmitter can be assigned a customized transmitter ID. This requires the use of the setup program, knowing that the customized transmitter ID has to be stored in the transmitter beforehand via the set-up interface.
8.2 Parameter level (PA) The parameter level comprises an extensive list of editable parameters that are grouped in a user-friendly manner. The key functions shown permit quickly browsing up and down or jumping from one group to another. In this level, the receiver is adapted to its task. Settings can be selected in the individual parameters or values entered within the factory-set limits.
Page 44
Recommended procedure: Step Action Read the parameter descriptions contained in Chapter 9 "Term definition". Enter the desired settings/values in the right column ! of the following tables. Individually select and edit the parameters one after the other. This is the only way to ensure parameter entry within the factory-set key timeout of 40 s, after the elapse of which the receiver automatically returns to the standard display.
