I/O Control Section
The I/O Control section hosts the I/O connectors and several displays and switches for
the system’s control.
Output connectors
The upper part of this area contains the OUTPUT connectors and relevant displays for
the check of the channel status.
Starting from left to right, these are:
•
OVC
(OVER CURRENT) output connector and relevant red LED – if it is TRUE
(relevant LED on), it indicates that at least one channel is in
Over Current
condition.
•
UNV
(UNDER VOLTAGE) output connector and relevant red LED – if it is TRUE
(relevant LED on), it indicates that at least one channel is in
Under Voltage
condition.
•
CHK PASS
(CHECK PASSED)
output connector and relevant green LED – if it is
TRUE (relevant LED on), it indicates that the initial check of the system has been
successful and that the system is ready.
•
TRIP
output connector and relevant red LED – if it is TRUE (relevant LED on), it
indicates that at least one channel is in
Trip
condition.
•
OVV
(OVER VOLTAGE) output connector and relevant red LED – if it is TRUE
(relevant LED on), it indicates that at least one channel is in
Over Voltage
condition.
•
RST FLAG
(RESET FLAG) output connector and relevant red LED – if it is
TRUE (relevant LED on), it indicates that a RESET occurred according to the
user’s settings (refer to the
User’s Manual
for the setting of the conditions on the
RESET FLAG, which allows as well to enable the different types of resets).
Moreover, on the right there are the following output components:
•
GEN
(GENERAL STATUS) output connector and relevant red lamp - if it is TRUE
(relevant lamp on), it indicates that the logic combination, set by the user, of
OVC, UNV, OVV and TRIP is TRUE.
•
CH-ON
(CHANNEL ON) output connector and relevant red lamp – if it is TRUE
(relevant lamp on), it indicates that at least one channel is ON.
For a detailed description of the mechanical and electrical characteristics of these output
connectors please refer to the Technical Specifications in Section 4.3, p.36. A summary
of their characteristics is also given in the Reference Table 2.2 and Table 2.3, p.15.
A two-position lever
NIM/TTL Switch
which allows to select either the NIM or the TTL
standard for the status/control output signals is placed just underneath the output
connector section. If the NIM standard is selected, the relevant green LED will light up. If
the TTL standard is selected, the relevant TTL green LED will light up.
Input connectors
The area in the middle contains the INPUT connectors and relevant displays for the
control of the channel status.
Starting from left to right, these are:
VSEL
(VOLTAGE SELECTION) input connector and relevant green LED – it
allows to select one of the two voltage values, V0SET and V1SET, programmed
for the relevant channel. If the VSEL input is FALSE, the selected voltage value
is V0SET (LED off); if it is TRUE, the selected voltage value is V1SET (LED on).
