the I/O signals to the equipment. We suggest a shiel-
ded ribbon cable. Refer to wiring diagram at page 12.
V) The CONN# 10 is present only in version 1. The
type of socket is RJ 45.
VI) The USB on rear panel is a standard serial port,
that can be used to upgrade the software from a PC, or
to retrive internal data through FrontPanel GUI. Look
the pin-out at page 12.
VII) The user must provide external cut-off device, to
protect the SG 1024 from short-circuit and thermal
runaway; this external protection device must also
switch-off the main line for maintenance operations.
VIII) The external circuit breaker must be a 2-pole
current limiter breaker and must comply the norm
EN61010-1.
IX) The external circuit breaker must be in close
proximity of the equipment and within easy reach of
the operator.
X) The external circuit breaker must be marked as the
disconnecting device for the SG 1024.
XI) The connector #1 must never be used as a switch-
off device.
Failure to comply with these instructions may
involve considerable risks for the staff responsible
for checking and using the equipment, as well as
the risk of general malfunctions of the equipment itself.
Equipment operation
Power-up procedure
Before powering-up the equipment, double check to have pro-
perly connected it, (look at the chapter “Wiring Instruction”
for any doubt) then power on the unit through your external
contactor.
Once switched OFF wait at least two seconds before setting it
ON again.
The OFF state, between two consecutive ON state, must last
two seconds minimum.
The following description is valid for any versions, but with
the “Display” version the user will be updated of status
through the display messages.
At power on the unit enters into a “BOOTLOADER” state for
few seconds to allow firmware upgrade, then it goes immedia
-
tely into “READY”.
In order to produce microwave and enter in “MW-ON”, the
Enable signal has to be set ON and then the reference signal
has to be set beyond the threshold of 1% (> 0.1 V): both
signals are available through the “D-SUB” CONN #2.
If any alarm is present, the unit remains in Alarm state until
the alarm is removed.
The reset of the Alarm should be made setting the Enable
command OFF for two seconds.
In absence of alarms the power supply may be left in “Ready”
continuously: when it receives the enabling command (ON) it
a wooden case and a proper filler: movement of the equipment
inside the package must be avoided.
Warning for handling:
use handles only for help during
installation.
Never use handles to lift the rack: the handles
don’t withstand the off-center weight of the rack!
To lift always lean the rack over a proper supporting base.
Wiring instructions
The SG 1024 must be installed and serviced only by quali-
fied personnel acquainted with the regulations covering the
application. For safety operations the following rules must be
adopted:
I) The equipment must be grounded through the connector
#1 using pin 3
(see the wiring diagram at page 10).
II) The main supply must be provided through connector #1:
connect phases according to schematic at page 10, the con-
nector’s pins can house wires with gauge up to 4 mm².
Warning: this connector is not intended for live insertion
of the unit: an external breaker must always be provi-
ded, and the unit must be switched off before inserting/
unplugging of the connector.
III) The connector #3 is a standard, coax
7/16 socket
(female): use a proper coax cable to carry microwave
energy to your load (cavity).
Alter may supply specific cable as per cusotmer specifica
-
tion, connector adaptors, and a transition coax to wave-
guide (WR 340 or 284 size).
IV) The “D” type female connector #2 has 25 pins and brings
