RLTK420 | QUICK START GUIDE
If the communication between devices is not healthy and there are constant breaks, RSSI
measurement should be done. If the value obtained in the signal strength measurement is 55 or less,
check the antenna connections. If the problem continues, consult the technical team.
6- When the Signal is Applied to the Digital Input, the Input LED is not Lit!
The signal applied to the inputs must be between 10-24VDC and should deliver at least
10mA. Applying high voltage can damage the device. If the problem continues,consult the technical
team.
7- Device Digital Output Led Is On But No Output!
If the led lights up when trying to get a digital output from the device, but the output cannot
be obtained, high current may have been drawn from the outputs before or there may be a faulty
connection. Consult the technical team.
8- Device Heats Up and Does Not Communicate!
If the Device is getting hot, liquid contact in the device and previously made faulty
connections may cause this situation. Cut the power of the device and consult the technical team.
Safety Warnings
●Inverted or incorrect power and communication connections in the device may cause
permanent damage to the device and the device to which the device is connected.
●Devices use electromagnetic waves to communicate, thus the communication can be
interrupted or permanently lost if a high electromagnetic source is placed near the
modem such as base stations and high power electric machines.
●Wireless performance may vary depending on the environment. In this respect, it is
recommended to make all kinds of measurements in the application area.
●The device should be used in a way not to be exposed to high humidity, high heat and
direct sunlight. Otherwise, permanent damage may occur in the device.
●The device is not protected against liquid contact. In these cases, permanent damage
may occur to the device and the devices it is connected to.Consult the technical team
●The device should not be subjected to high concentration. In other words, it should
not be taken from a low temperature environment to a high temperature environment.
●The device is not resistant to drops and impacts. Permanent damage may occur on the
device as a result of falling and impact.
