Interlock Enable/Disable Mask
The NGPS series external interlock can be enabled or disabled by writing to the
corresponding Interlock Enable/Disable Mask field of the advanced configuration
parameters (field #90), using the MWG command.
Please refer to
the
Remote Control
Manual
for more information.
Interlock Activation Level Mask
Each external interlock can be chosen to trip at high or low logic level. The
high-level means that the interlock trips when the interlock input signal is shorted,
otherwise with low-level the interlock trips when the input is open. To configure the
interlock state mask, it is necessary to write on the advanced configuration parameters
(field #91),
please refer to
the
Remote Control Manual
for more information.
Interlock Intervention Time
The module allows to set also the interlock intervention time (how long an
interlock signal needs to be at its activation level before tripping and thus generating a
fault condition). The intervention time parameters are stored from field #92 to #96 for
Interlock #1 to #4, respectively. Please refer to the
Remote Control Manual
for more
information.
Interlock Identification Name
The NGPS also allows associating a name to the interlocks in order to read form
the remote interface or to display on the local display the interlock condition name. The
intervention names are stored in the field #93 for Interlock #1, in field #95 for Interlock
#2, in field #97 for Interlock #3 and in field #99 for Interlock #4. Please refer to the
Remote Control Manual
for more information.
Output Status
The magnetic relay provides the output status of the power module: when the
module is ON, the Normally Closed contact (NC-TAP) switch opens and vice-versa.
Instead, the solid state relay is closed when the module is ON. The absolute maximum
current that can be sunk by the relays are shown in the following table:
