the I/O signals to the equipment. We suggest a
shielded ribbon cable. Refer to wiring diagram at
page 12.
V) The CONN# 4 is present only in version 1. The
typeofsocketdependsontheeldbusinterface:
- RJ 45 on Ethernet-Modbus TCP
-9pin“D”onCANopen/Probus
VI) The USB on front 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 524 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 discon-
necting device for the SG 524.
XI) The connector #1 must never be used as a switch-off
device.
Failure to comply with these instructions may involve con-
siderable risks for the staff responsible for checking and
using the equipment, as well as the risk of general malfun-
ctions 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
fewsecondstoallowrmwareupgrade,thenitgoesimmedia-
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.
Handling instructions
The equipment weight is 14 kg (31 lbs). Always lift from the
bottom and use a rugged support to avoid personal injury and
damage to equipment itself.
In case of shipping, package with the original package or use
awoodencaseandaproperller:movementoftheequipment
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 524 must be installed and serviced only by quali-
edpersonnelacquaintedwiththeregulationscoveringthe
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 11).
II) The main supply must be provided through connector #1:
connect phases according to schematic at page 11, 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).
-
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
