Multi-functional modules
(clock and/or non-optoisolated TTL/RS-485 serial interface)
EVIF22TSX & EVIF23TSX
– clock (not available for EVIF22TSX)
– TTL MODBUS port (input)
– RS-485 MODBUS port (output).
MEASUREMENTS AND INSTALLATION
Measurements in mm (inches); to be fitted on a rigid support, with a cable tie (not provided
INSTALLATION PRECAUTIONS
– Ensure that the working conditions are within the limits stated in the TECHNICAL SPECIFICATIONS section
– Do not install the device close to heat sources, equipment with a strong magnetic field, in places subject to direct sunlight, rain, dampness, excessive dust, mechanical vibrations or shocks
– In compliance with safety regulations, the device must be installed properly to ensure adequate protection from contact with electrical parts. All protective parts must be fixed in such a way as to need the aid of a tool to remove them.
ELECTRICAL CONNECTION
 |
N.B. – Use cables of an adequate section for the current running through them – To reduce any electromagnetic interference connect the power cables as far away as possible from the signal cables and, if necessary, connect to an RS-485 MODBUS network by using a twisted pair. |
Example of electrical connection to a controller belonging to the EV3 series.
| LED | ON | OFF | BLINKING |
| TTL MODBUS | – | no TTL MODBUS activity | TTL MODBUS activity |
| RS-485 MODBUS | – device power up – waiting RS-485MODBUS data |
no RS-485 MODBUS activity | RS-485 MODBUS activity |
Fitting the termination resistor of RS-485 MODBUS network
To fit the RS-485 MODBUS network termination resistor, place the micro-switch in position ON.
PRECAUTIONS FOR ELECTRICAL CONNECTION
– If using an electrical or pneumatic screwdriver, adjust the tightening torque
– If the device has been moved from a cold to a warm place, the humidity may have caused condensation to form inside. Wait about an hour before connecting it to the controller
– Disconnect the device from the controller before doing any type of maintenance
– For repairs and for further information, contact the EVCO sales network.
FIRST-TIME USE
- Install following the instructions given in the section MEASUREMENTS AND INSTALLATION.
- Disconnect the device from the mains; see the relative instruction sheet.
- Connect the TTL MODBUS port of the device to the TTL MODBUS port of the controller as shown in the section ELECTRICAL CONNECTION.
- Connect the RS-485 MODBUS port of the device to the RS-485 MODBUS network as shown in the section ELECTRICAL CONNECTION.
- Power up the controller and an internal test of the device will be run.
The test normally takes a few seconds, when it is finished the LED of the device will switch off. - If EVIF23TSX is used, the controller shows the label “rtc” flashing: set the date and time of the controller.
Do not disconnect the device from the mains in the two minutes following the setting of the date and time.
