Responding to Alarms, Faults and Warnings
Users may respond to alarms and other events by various methods.
All users may view events, as described below.
Events may be acknowledged or reset by various methods, including the controller front panel
Accept
and
Reset
buttons,
touch screen menus, remote DIM-controlled switches, and, if enabled, Webserver and Modbus.
Access to controller
Accept
and
Reset
functions may be restricted to logged in users. The system may be configured so
that the
Accept
and
Reset
buttons are password protected and require a user to login. See
Ch. 6 Software setup and
Commissioning
for further information.
Note
: Switches and buttons connected to DIM channels may be used to provide remote
Accept
,
Reset
and
Inhibit
functions. These inputs cannot be password controlled so it is the user’s responsibility to limit access, if required, by using
other methods such as key operated switches. See
Ch. 6 Software setup and Commissioning
for further information.
Note
: Alarms may be commissioned as
'Latched'
or
'Unlatched'
. Unlatched alarms self-reset once the hazard has cleared,
while latched alarms require the user to verify that conditions are safe/normal before manually resetting the alarm.
WARNING
Over range gas alarms should be investigated before attempts are made to reset them.
WARNING
High ‘off-scale’ readings may indicate an explosive concentration.
AVERTISSEMENT
Des résultats dépassant considérablement l’échelle peuvent être indicateurs d’une
concentration explosive.
