The menu item appears as: “Alarm1 Settings”
From the “Alarm1 Settings” text scroll, hold the magnet over PGM1 () or PGM2 () until the arrow
prompt appears and then hold continuously for an additional 3 seconds. The display will switch to “Set
Level” followed by “XX” (where XX is the current set-point level). Swipe the magnet momentarily over
PGM2 to increase or PGM1 to decrease until the correct level is displayed. Hold the magnet over PGM1 or
PGM2 for 3 seconds to accept the new value. The display will scroll “Saved”.
The display will then scroll “Set Ascending” and show “Yes” or “No”. Use a swipe of PGM1 to select
choice (yes = ascending and no = descending). Use PGM1 for a 3 second hold to accept the selection. The
display will scroll “Saved”.
The display will then scroll “Set Latching” and then show “Yes” or “No”. Use a swipe of PGM1 to select
choice (yes = latching and no = non-latching). Use PGM1 for a 3 second hold to accept the selection. The
display will scroll “Saved”.
The display will then scroll “Set Energized” and then show “Yes” or “No”. Use a swipe of PGM1 to select
choice (yes = energized and no = non-energized). Then use PGM1 for a 3 second hold to accept the
selection. The display will scroll “Saved”.
At this point, configuration settings for Alarm1 are complete and the menu will shift back to “Alarm1
Settings”. The user can then choose to either: 1) move to another menu item by executing a momentary hold
at the end of the text scroll, or 2) return to Normal Operation via 15 second automatic timeout.
Follow the identical instructional sequence for the menu function “Alarm2 Settings”. The menu function for
“Fault Settings” is similar except that it does not have a selection for gas level and ascending/descending. It
only has choice selections for latching/non-latching and energized/de-energized.
The Fault relay is typically set-up as energized so that it will change states during an
unexpected power loss.
The relay contacts can be wired at the RAM’s connector PCA for either Normally
Open or Normally Closed.
3.5 Signal Output Check
Signal Output Check provides a simulated 4-20mA output and RS-485 Modbus™ output. The simulation
allows the user to conveniently perform a functional system check of the entire safety system, and can be
initiated at the RAM. This signal output simulation aids in performing troubleshooting of signal wiring
problems.
This menu item appears as: “Signal Output Check”.
From the “Signal Output Check” text scroll, hold the magnet over PGM1 () or PGM2 () until the arrow
prompt appears and then hold continuously for an additional 3 seconds. Once initiated, the display will
continuously scroll “Simulation Active” until the function is stopped. During simulation mode, the 4-20mA
value will be increased from 4.0mA to 20.0mA (in 1% of range increments at a 1 second update rate) and
then decreased from 20.0mA to 4.0mA. The same simulation sequence is applied to the Modbus™ output
gas reading.
