Summary of Contents for Teracom TCG120

  • Page 2 Only one parameter can manage the relay at the same time, but for every parameter can be sent e-mail or SMS for alert conditions. TCG120 may periodically send data to a remote server, which makes it suitable for use in client- server monitoring and control systems.

  • Page 3: Technical Parameters

    SIG (red) – this LED is used to indicate the GSM network signal level;  STA (yellow) – indicates the working state of TCG120 controller and system messages. The controller states and system messages are shown in Appendix A. TCG120 _R1.1 - March 2015...

  • Page 4: Installation

    6.1. Mounting TCG120 should be mounted in a clean and dry location on not flammable surface. Ventilation is recommended for installations where ambient air temperature is expected to be high. Mount the device to a wall by using two plastic dowels 8x60mm (example Würth GmbH 0912 802 002) and two dowel screws 6x70mm (example Würth GmbH 0157 06 70).

  • Page 5: Power Supply Connection

    Attention! Digital inputs are NOT galvanic isolated. The TCG120 digital inputs can be used in two modes – “dry contact” and “logic level”. The mode is determined by the jumper, close to the corresponding input. To change the operation mode, the plastic enclosure must be opened.

  • Page 6: Sensor Connection

    6.2.4. Sensor connection Up to 4 1-Wire sensors can be connected to TCG120 controller. The device supports TSTxxx (temperature) and TSHxxx (humidity&temperature) sensors. 1-Wire is a registered trademark of Maxim Integrated Products, Inc. It is designed to connect several sensors over a short wiring. It is not suitable for long distances or environments with EMC interference.

  • Page 7: Relay Connection

    Although functionality has been achieved in longer distance, we cannot guarantee error-free operation over mentioned wiring length. We guarantee proper operation only with Teracom 1-Wire sensors. 6.2.5. Relay connection The relay contacts are internally connected directly to the terminal connectors. For all relays normally open, normally close and common contacts are available.
  • Page 8 7. Initial setup via USB The initial setup of TCG120 controller is done with a computer running Windows 7 or newer Microsoft Windows operating system. After power-up, the controller should be connected to the computer with USB cable. Once the USB cable is connected, the operating system automatically starts to install the drivers for the communication with the device.

  • Page 9: Monitoring Page

    If all sensors are locked, removing one “in the middle” will not change the positions of following sensors after reset. This option is very useful when TCG120 is used like a part of monitoring and control system managed either by SNMP or HTTP API commands.
  • Page 10 Pulse duration and parameters for local relay activation can be set separately for each relay in “Setup->Input/Output->Relay outputs”. For locally activated relays a text description of the controlling parameter is displayed rather than buttons. TCG120 _R1.1 - March 2015 Page 10...

  • Page 11: Digital Inputs

    - %RH Offset - 0.826 Multiplier - 31.74, the value is inversed of slope parameter (1/0.0315); If the output voltage of this sensor is 3.198V on the monitoring page will be shown 75.28% RH: TCG120 _R1.1 - March 2015 Page 11...

  • Page 12: Relay Outputs

    The remaining 4 recipients can receive SMS messages if any of the parameters is in alarm state and ask for parameter state/value by sending an SMS message. By pressing the “send test SMS” button all SMS recipients will receive a confirmation SMS message. TCG120 _R1.1 - March 2015 Page 12...

  • Page 13: Email Setup

    All changes in above sections are saved by pressing the “Save” button. 7.2.2.3. Phone call Setup The relay outputs of TCG120 controller can be controlled (only pulse) by a single call from authorized number. The maximum number of the authorized numbers is 100. These numbers can be set manually or by sending a SMS message from the Master.
  • Page 14 All above settings are valid also for the analog inputs. Example: TCG120, TST100 and appropriate heater are used to control the room temperature. The wanted minimum temperature is 19°C. The initial temperature is 17°C. TST100 is assigned on the first position for 1-Wire sensors.
  • Page 15 In the example above email alert will be sent if there is low level (state Open) on digital input 1 and SMS message will be sent if there is a low level (state Empty) on digital input 2. All changes in above sections are saved by pressing the “Save” button. TCG120 _R1.1 - March 2015 Page 15...
  • Page 16 5 - when the Push period timer expires, TCG120 sends new HTTP POST request to the server 6 – the server answers with “set FIN” – there is no pending commands and the session can be closed.
  • Page 17 The “Key” field value is sent in the XML data and can be used for device identification. If “Process Answer” option is enabled, the TCG120 controller will be able to process the commands, which are sent from the remote server. The valid commands are described below:...

  • Page 18: Time Setup

    7.2.5.2. Time setup TCG120 controller is equipped with a real-time clock. Time setup is performed in this section. The following parameters can be set:  Time server – it is possible to choose between 2 public time servers and custom Time server (NTP server);...

  • Page 19: Firmware Update

    8. Device setup via SMS TCG120 controller supports 5 SMS users (Master + 4 users). The Master is able to configure some of the system parameters by SMS messages as well as to receive alarm and status messages. The rest 4 SMS users are able only to receive alarm and status messages.

  • Page 20: Factory Default Settings

    10. Factory default settings TCG120 can be restored to its original factory default settings, following the steps below:  Turn off the power supply;  Press and hold the RESET button then turn on the power supply;  STA and SIG LEDs will turn ON;...
  • Page 21 LEDs will display the level of the GSM signal. STA LED will flash once every 2 seconds (flash length– 200ms.) This indication ensures that TCG120 is connected to the network. If STA LED flashes twice – this indicates that GPRS connection is established. Between the STA LED flashes, SIG LED will indicate the signal strength: 1 flash (200ms.) means that signal strength is between 0 and 20%, 2 flashes –...
