2.2. LEVEL ITW TRANSMITTERS
The transmitter function is to transmit any variation in the state of the digital inputs, and time
to time send a signal with the current state of the digital and/or analogical inputs to refresh the
information to the receiver, on this way it is also verified there is not communication failure
between the equipments.
2.2.1. INSTALLATION OF THE TRANSMITTER
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.
NOTICE: WHEN RAISING THE TOP, BE SPECIALLY CAREFUL WITH THE
CONNECTION HOSE OF THE MOTHER BOARD TO THE DISPLAY CIRCUIT
(LEDS OR LCD SCREEN)
2.2.2. CONNECTIONS OF THE LEVEL ITW TRANSMITTER
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.
For models with analogical inputs, the value of the analogical inputs is configured on the
factory with one of the following ranges: 0-20mA / 4-20mA / 0-5V / 0-10V, but depending on
the model it can be changed through the jumpers of the following table.
Input

0 - 5Vdc J5 J6 J7 J8
0 – 20mA J1 – J5 J2 – J6 J3 – J7 J4 – J8
