Installation Rules
Electrical Connections
The module is designed to be installed in vertical position on a DIN 46277 rail. In order to
ensure optimum performance and the longest working life, the module(s) must be supplied
adequate ventilation and no raceways or other objects that obstruct the ventilation slots.
Never install modules above sources of heat; we recommend installation in the lower part of
the control panel.
As it is illustrated in the next figure:
1) Insert the rear IDC10 connector on a DIN rail
free slot (the inserting is univocal since the
connectors are polarized).
2) Tighten the two locks placed at the sides of the
rear IDC10 connector to fix the module.
POWER SUPPLY AND MODBUS INTERFACE
Power Supply and CAN/MODBUS interface are available by using the bus for the Seneca
DIN rail, by the rear IDC10 connector or by Z-PC-DINAL2-17,5 accessory.
Rear Connector (IDC10)
Z-PC-DINAL2-17,5 Accessory Use
In the figure the meaning of the IDC10
connector pins is showed, in the case
the user decides to provide the signals
directly through it.
In case of Z-PC-DINAL-2-17,5
accessory use, the signals may be
provided by terminal blocks. The
figure shows the meaning of the
terminals and the position of the DIP-
switch (present on each DIN rail
supports listed on Accessories) for
network termination (not used in case
of Modbus network).
GNDSHLD: Shield to protect the
connection cables ( recommended).
Inserting on the DIN rail

1) Install the modules on the DIN rail (max 120).
2) Connect the remote modules using cables of proper length. On the table the following data
about the cables length are provided:
-Bus Length: Modbus network maximum length as a function of the Baud rate. It is the lenght
of the cables which connect the two bus terminators modules (see Scheme 1).
-Drop Length: maximum length of a drop line 2 m (see Scheme 1).
Scheme 1
For the best performances, the use of special shielded cables is recommended (BELDEN
9841 cable for example).

be externally supplied.
Procedure for modifying the configuration of
the inputs: open the side lid and shift the
configuration jumper J1 to position Int for
internal power supply, or in position Ext for
external power supply (see fig. 2).

MODE
To start the motor, close the "START" input. The module controls if the "THERMAL
PROTECTION" and "STOP" inputs are closed - in this situation it enables the "START"
output.
After the programmed time (see DIP-switches SW2-3 and 4 and modbus 40005 register) the
closure of the “FEEDBACK” input is verified. If still open, the module enables the "ALARM"
output (the "START" output remains enabled).
If the "THERMAL PROTECTION" input opens during operation, the "ALARM" output is
immediately enabled, and the "START" output is disabled.
To silence the alarm, close the "SILENCE ALARM" input.
To stop the motor, open the"STOP" input - the module disables the "START" output.
The "FEEDBACK" input must open within the programmed time, otherwise the module
enables the "ALARM" output.

( * ) These commands are effective only if the Local / Remote input is in Local position
(open contact). If the Local / Remote input is in Remote position (closed contact), the
respective commands are sent to the module by writing in the respective registers.

MOTORS COMMAND LOGIC (in LOCAL mode)
PNEUMATIC VALVE COMMAND LOGIC
(in LOCAL mode )
To enable the pneumatic valve, close the "ACTIVATION" input. The module controls if the
"RETURN" input is closed - in this situation it enables the "ACTIVATION" output.
After the programmed time (see DIP-switches SW2-3 and 4 and modbus 40006 register), the
opening of the "ACTIVATION TRAVEL-LIMIT" input is verified. If it is still closed, the module
enables the "ALARM" output (the "ACTIVATION " output remains enabled).
To silence the alarm, close the "SILENCE ALARM" input.
If you open the "RETURN" input, the module disables the "START " output.
The "RETURN TRAVEL-LIMIT" input must open within the programmed time, otherwise the
module enables the "ALARM" output.
An incongruous situation of the travel-limit devices (simultaneous opening of the two inputs
"ACTIVATION TRAVEL-LIMIT" and "RETURN TRAVEL-LIMIT") immediately activates the
"ALARM" output and lights up the "FAIL" LED..
