2.2. BIDIRECTIONAL LEVEL ITW
The function of the MASTER equipment is to manage the communication with the SLAVE. This
equipment is establishing the initial communication. When connecting the first time the
equipment is transmitting the state of the digital inputs and refreshing the state of its outputs
activating/ deactivating the corresponding relays, depending on the state of the inputs in the
SLAVE equipment.
The installation and connection of MASTER and SLAVE equipments are identical.
When you connect the power for first time to the equipments, the incidence relay is activated
(FE) and the following message is displayed “COMMUNICATION FAILURE” in the LCD screen.
When the communication is established between both equipments, this relays is disconnected
due there are not incidences. In case of communication failure, voltage fault, etc. the
equipments will disconnect the relays that were activated and the incidence relay (FE) will be
activated and the corresponding message is appearing on the LCD display.
NOTICE: IF WE ARE GIVING POWER FIRST AT THE SLAVE EQUIPMENT, THE
INCIDENCE RELAY WILL BE CONNECTED IN THE SYSTEM INDICATING THE
FAILURE ON COMMUNICATION, WHILE THE MASTER IS NO CONNECTED TO
THE VOLTAGE
2.2.1. INSTALLATION OF THE EQUIPMENT
NOTICE: BEFORE ANY HANDLING, CHECK THAT THE EQUIPMENT IS NOT
CONNECTED TO THE NET NOR HAS ANY VOLTAGE, OTHERWISE MUST BE
DISCONNECTED.
The equipment is designed to get an easy and quick installation.
It is recommended to install the equipment in a place protected from the inclemency of the
weather, as well as to put it in a fix place. To facilitate this operation we are supplying the
equipment with some holes that allow fixing it to a wall or at any other element with screws
and studs.
2.2.2. CONNECTIONS OF THE EQUIPMENT
NOTICE: WHEN RAISING THE TOP, BE SPECIALLY CAREFUL WITH THE
CONNECTION HOSE OF THE MOTHER BOARD TO THE DISPLAY CIRCUIT
(LEDS OR LCD SCREEN)
The outputs of the elements and / or measuring instruments must be connected to the
transmitter inputs, such as: buoys, alarms, magneto thermal jumps, stop / start confirmation,
etc.
To facilitate the connection of these signals to the circuitry of the equipment, there are various
terminals for this purpose, also in the following pages are attached the wiring diagrams of the
equipments.
The control elements of the pumps or machinery are connected with the receiver through the
relays outputs.
