Moreover it is possible to monitor board temperature and to check board status; the
following messages may be returned by the SYX527 when monitoring the board status:
•

3.2
Output Enable
The following procedures must be performed in order to enable the board's operation:
Provide the "HV EN" connector with a 50 Ohm termination.
-
-
Provide short circuit between Pin 51 and Pin 52 (IINT and IEXT) of the HV Multipin
Connector (see Fig. 2.2); this is a safety feature to verify that the connector is plugged
and the channels are connected to their loads (see § 1.4.2). This operation is not
necessary if the S1 pins on the PCB are short circuited.
Such procedures are unnecessary if the S2 pins on the PCB are short circuited.
S1 and S2 are placed on the PCB's lower edge, just behind the front panel.
When the channels are disabled the voltage outputs drop to zero at the maximum rate
available; when the output disable cause is removed, the channels remain OFF until the
User turns them ON via software.
3.3
Full scale range setting
The output voltage and current full scale range, common to all channels, can be selected
by dip-switches (please refer to the Fig. 3.1 for the dip-switches location on the board).
NPO :
00101/00:17XXx.MUTx/08
(channel in OVERVOLTAGE condition)
(channel in UNDERVOLTAGE condition)
(channel OFF due to external TRIP line signal)
(channel OFF due to internal OVERCURRENT condition)
(channel disabled by board INTERLOCK protection)
(board temperature < 5°C )
(board temperature > 65°C)
