3.3 LED indicators located on the board are used to indicate the operating modes and
status of the device. The purposes of the indicators are as follows: (Fig. 1):
1) HL1 (green):
-blinking 1 time in 4 s - standby mode indication;
-blinking with an interval of 0.5 s (for not more than 4 s) - indication of the device
registering process in the AI.
2) alternating blinking indicators HL1, HL2 - the device is marked for visual search in the
zone.

4 CONNECTIONS
4.1 To access the terminals of the device, unscrew the 2 screws on the underside of the
housing (Fig. 1) and remove the cover. Connect the device to the AI and actuators according
to Figure 2

- Positive wires of AI - wires connected to terminals L1-L4;
- Negative wires of AI - wires connected to terminals G1-G4.
b) connection diagram of the activation device (relay with NO contact) in parallel with the
terminal resistor Rt.

The activation device is shown as a relay for example.
Also, it is possible to use the button as the activation device, when the resistance of
the line provided according to table 2.
The value of the terminal resistor (Rt) shall satisfy the conditions of formation of the
standby mode in accordance with table 2.
The value of the additional resistor (Rl) must satisfy the conditions of formation of the
active mode (table 2) when the relay (button) triggered.
Notes.
1. When choosing the values of resistances Rt and Rl, you should take into account the
total resistance of the line when the relay is activated, this value should not be equal
to Rd - the resistance of the indeterminate state of the line. Rd is 100 ohms between
the ranges of inputs modes.
2. Switching the device to activation warning mode is only possible from the standby
mode. In the event of a fault (line short circuit or line open circuit), the device can be
restored when returning to the standby mode.
4.2 Wires inside the housing should be laid in such way that they do not interfere with
closing the cover and do not fall between the indicators and the window in the housing cover.
4.3 Wires can only be connected to the terminals of the device when there is no voltage
from external power supplies.
5 SETTINGS
5.1 When the supply voltage appears in the AI on the connected device, the automatic
registration indication (3.3) is switched on. Then the device goes into a mode that depends on
the inputs settings and the state of external devices connected to it (Fig. 2).
The inputs of the device are set according to the FCP operation manual.
5.2 By default, the outputs of the device are set to "Not used".
6 PACKAGING
6.1 After unpacking the device it is necessary:
- visually inspect the device and make sure there is no mechanical damage on it;
- check the delivery set according to table 3.
