"Analysis Time" - This numerical entry element is the analysis time and is defaulted to 90 seconds
and has a valid entry range of 10-300 seconds. The slowest responding of the 4 sensors attached to
the MultiGard 5000 system determines the appropriate value for this entry.
"Extended Analysis Time" - This numerical entry element is the extended time the user requires
when any of the extended analysis time conditions (rate, increase, decrease) become true. By default
it is set to zero seconds and has an entry range of 0-180 seconds.
"Step to Point #" - This push button sequentially steps through all point numbers for the purpose of
viewing or entering the transport times per point.
"Select Point #:" - This numerical entry element allows direct entry of a point number for the purpose
of viewing or entering a sample transport time.
"Transport SMPL Time:" - This numerical entry element is the sample transport time for the selected
point. By default all transport times are zero and have an entry range of 0-300 seconds.
"System Menu" – An HMI navigation button which switches the screen back to the System Setup
Menu.
4.2.7 Sequencer Point Bypass
The Point Bypass screen allows the user to stop the sampling of any of the available points in the
MultiGard 5000 System. This is necessary when all available points are not being used or they are
temporarily taken out of service.
NOTE: Bypassing a point (eliminating a point from the sampling sequence) that has a sample or
bypass flow loss indication, will lead to a situation where the trouble condition cannot be cleared.
The MultiGard 5000 unit must access the line in question to determine that the fault condition has
been corrected whereby the CONDITION ACKNOWLEDGE button may be used to return the unit to
the normal operating state.
