Module installation and connection procedure

  1. Install the module in the switchboard on the DIN rail and fix it with the special latch on the module base.
  2. Connect the CAN connector.
  3. Connect the inputs and outputs.
  4. Configure the module using LT setup.
  5. Apply power to the load.
  6. Check all equipment for proper operation.

Module shut-off and deinstallation procedure

  1. Disconnect the power from the load.
  2. Disconnect the inputs and outputs.
  3. Disconnect the CAN connector.
  4. Remove the module from the DIN rail, releasing the latch at the bottom of the module base.

HW Settings

Example: leak='LLLL'

Name Type, range SUBID Default Description
runtime integer 0-100 1-4 15 runtime is the open/close time in seconds, is used for jalousie, gate, valve(2 pole); Example: runtime=15
hold integer 0-10000 1-4 500 hold is the bridging time in miliseconds, is used for gate and jalousie (by default hold is the same as runtime), lock; Example: hold=3500
def string 'ON' 1-4 'OFF' Def is the element status is set after restart, is used for lamp, heating, valve(1 pole); Example: def='ON'
out char[4] 98 'V-V-' Each char is responsible for the type of a particular channel

  • 'L'-Lamp;
  • 'M'-Lamp Inverse;
  • 'J'-Heating NO, valve-heating, normally open;
  • 'H'-Heating NC, valve-heating, normally closed;
  • 'B'-Blinds (2 pole), jalousie/curtains;
  • 'C'-Blinds Inverse (2 pole), jalousie/curtains, invert open-close;
  • 'G'-Gate (2 pole), 2 pole gate;
  • 'D'-Gate (2 pole) Inverse, 2 pole gate, invert open-close;
  • 'X'-Gate (1 pole /short press), 1 pole gate;
  • 'Z'-Gate (1 pole) Inverse, 1 pole gate, invert open-close;
  • 'V'-Valve (2 pole), 2 pole valve;
  • 'W'-Valve (2 pole) Inverse, 2 pole valve, invert open-close;
  • 'R'-Valve (1 pole), 1 pole valve,;
  • 'S'-Valve (1 pole) Inverse, 1 pole valve, invert open-close;
  • 'K'-Lock (short press);
  • 'N'-Lock (short press) Inverse;
  • 'P'-Blinds (2 pole);
  • 'O'-Blinds Inverse (2 pole), invert open-close;
  • '-'-none, nothing is connected.

Example: out='V-V-'

leak char[4] 98 'LLLL' Each char is responsible for the type of a particular channel

  • 'L'-Leak, Built-in floor (EW-WL) or on-the-floor (FW-WL) leakage sensor
  • 'N'-Third party leakage sensor;
  • 'S' – Leak, on-the-floor (FW-WL.B) leakage sensor
  • '-'-none
in char[2] 98 'KK' Each char is responsible for the type of a particular channel

  • 'K' – Contact;
  • 'H' – Inverted contact;
  • '-' – none;

Example: in='HHKK'
