MTREL-100 Relay Module

The relay module MTREL-100 is a switching module for heavy loads from myTEM for extending your smart home system with additional 16 A outputs. For this, the device is connected to your central myTEM Smart Server via the CAN bus system.
The programmable behavior allows a flexible use of the device in the house.

SAFETY INSTRUCTIONS

• Operate this device only as described in the manual.
• Do not operate this device if it has obvious damage.
• This device shall not be altered, modified or opened.
• This device is intended for use in buildings in a dry, dust-free location.
• This device is intended for installation in a control cabinet. After installation, it must not be openly accessible.
• Electrical equipment may only be installed and fitted by qualified electricians who are familiar with and comply with the applicable regulations and standards.
• CAN bus and device supply must comply with the ELV requirements. Do not connect ELV and mains voltage together. (ELV = extra-low voltage)
• If several motors are to be connected in parallel at one output, be sure to observe the manufacturer’s instructions and, if necessary, use isolating relays. Otherwise the device may be damaged.
• Only use blind motors with mechanical or electronic limit switches. Limit switches must be checked for correct adjustment. Otherwise the device may be damaged.
• Do not connect three-phase motors, the device may be damaged.

Applications:

• Switching of high current devices
• Switching of power outlet sockets
• Switching of lights
• Switching of single-phase fan motors
• Switching of electric blinds or similar shading devices
• Operation by means of buttons, sensors via the central server

Functions:

• Supply voltage 24 VDC ± 10% with support terminals for further wiring CAN bus 12 digital outputs with potential-free relays 16 A, 250 VAC or 30 VDC (DO1 ­ DO12) Manual positions of the outputs via DIP switch for easy commissioning The device is installed in a control cabinet, mounted on a 35 mm DIN rail
  WARNING! The maximum current across all relays must not exceed 48A.

Installation

WARNING! Depending on national safety standards, only authorized and/or trained technicians may be allowed to perform electrical installations on the power grid. Please inform yourself about the legal situation before installation.

Please install the device according to the following steps:

1. WARNING! Make sure that the device is disconnected from the power supply or that the devices in the control cabinet are disconnected from the mains.
2. WARNING! Connect the device according to the circuit diagram of the myTEM ProgTool or the terminal assignment from the picture above. Incorrect wiring can result in injury or death or damage the device.
3. CAUTION! The device shall only be operated with stabilized power supplies (24 VDC). Connecting to higher voltages will damage the device.
4. The last device on the CAN bus requires the terminating resistor of 120 enclosed with the myTEM Smart Server via terminals (CAN +/­).
5. WARNING! Switch on the power supply and, if necessary, check the wiring with the manual positions via the DIP switch. Take care of your safety as the devices are live.

LED display

The LED next to the CAN connector may show the following states:
LED green: Device started and connection to the myTEM Smart Server or myTEM Radio Server working
LED flash- Device is in manual position ing green:
LED red: Device started but no connection with the myTEM Smart Server or myTEM Radio Server
LED off: Device not powered, not started or broken

Manual positions via DIP switch

With the aid of the DIP switch, the outputs (exception output DO12) can be checked after installation.

• CAUTION! While manual settings are used, the control commands from the myTEM Smart Server or myTEM Radio Server are ignored.
• CAUTION! Before starting, set all DIP switches to position OFF, i.e. upwards. This avoids that e.g. OPEN / CLOSE commands are set at the same time.
• To check the digital outputs (relays) set DIP switch 12 down to ON.
  With the DIP switches 1 – 11 you can now switch the relays DO1 ­ DO11 on and off.

Behavior after power failure

After a power failure, all outputs are switched off until the new settings are received from the myTEM Smart Server or myTEM Radio Server.

Quick troubleshooting

The following hints may help solving trouble:

1. Make sure that the power supply is connected with the correct polarity. With wrong polarity the device does not start.
2. If a device cannot establish communication to the myTEM Smart Server or myTEM Radio Server, check if the CAN bus (+/­) is correctly wired and the ground (GND) is connected. A missing ground connection (usually available via power supply) can affect the communication.
3. If a device cannot establish communication to the myTEM Smart Server or myTEM Radio Server, check whether the terminating resistor of 120 at the last device is connected to the CAN bus. If missing, please add it via terminals (CAN +/­).
