COMMISSIONING PROCEDURE
5.1
CHECKS
1.
Make sure that the conditions in which the terminal will operate are suitable (see section
OPERATING AND STORAGE CONDITIONS
in manual
General Description
).
2.
Make sure with the help of a multimeter, that the power-supply voltage is within the
range specified for the operating nominal voltage and, in the case of DC supply-voltage
operation, that the polarity is correct.
3.
Make sure that the earth cables of the modules are connected correctly.
4.
Make sure that the connector (or connectors) of the line interface module (or modules)
are connected correctly.
5.
Make sure that the connectors of the MWTU processing module are connected
correctly.
6.
As far as programming is concerned, it must be taken into account basic concepts such
as: operation of the line interface module (or modules), number of commands in
transmission and reception, input and output logic desired, duration of command
transmission, duration of command output, activation condition of the auxiliary
relays, etc.
5.2
MODULE CONFIGURATION
Without the power supply being connected, configure in the IPTU modules the nominal
activation voltage of the command inputs. To do so, set the jumpers shown in Figure 7.
The modules contain components sensitive to static electricity, so great care must be
taken when handling them. It is advisable to use an antistatic wristband connected
to earth.
