Settings SIL activation
This function protects the instrument against unauthorized
changes. Changing the configuration (e.g., changing the
measuring range from 100 %LEL to 50 %LEL) will force the
user to confirm all safety-relevant parameters before the
instrument returns to normal operation.
1. Select
Settings > Instrument > SIL activation
. The
sensor test dongle or sensor diagnostic dongle must be
connected for SIL 2 activation and operation.
2. Select
Enable
or
Disable
and confirm.

Combinations of acknowledgments,
latching and the corresponding relay/
LED status
This section gives explanation of combining latching,
acknowledgment and pre-acknowledgment of alarms and the
corresponding LED status.
5.7.1
Acknowledgments and latching
Latching means that once the alarm level is reached, the
instrument will trigger the alarm. It will remain in alarm status
even if the gas concentration subsequently does not meet the
alarm condition any more. To clear a latching alarm it has to be
acknowledged with [OK].
In non-latching mode, the alarm status clears if the gas
concentration does not meet the alarm condition anymore.
Acknowledgeable means that alarm relay and LED can be
reset before alarm condition clears.
Pre-acknowledgeable means that the alarm status is
acknowledgeable before the alarm condition clears.
However, the alarm relay and LED stay active until the
alarm condition clears.
Non-acknowledgeable means that alarm relay and LED
can not be reset until the alarm condition clears.
5.7.2
LED status:
When the first alarm (pre alarm) has been triggered the red
LED flashes in single mode.
When the second alarm (main alarm) has been triggered
the red LED flashes in double mode.
With the non-relay version the red LED flashes to inform
visually and no relay is energized. To energize the A1 or A2
relay the optional relay board must be installed.
For LED flashing patterns depending on combinations of
acknowledgements and latching, see 5.7.3 on Page 20.
NOTICE
SIL lock is only available for certain sensors (refer to
the Polytron 8xx0 Safety Manual part number
9033307).
SIL lock can only be activated if the sensor test is
activated see Section 5.10.9 on Page 28.
NOTICE
When SIL is activated, the instrument displays all
safety-relevant parameters and settings before
returning to normal operation. Carefully review all
parameters and settings and confirm.
