Detcon 700 Series Remote Sensor/Alarm Relay Module With Profibus DP Interface - Manual (Page 13)

700 Profi-RAM
The user can then choose to either: 1) move to another menu item by executing a momentary hold, or 2) return
to Normal Operation via 5 second automatic timeout.
3.3 Set Serial ID
The Profi-RAM can be polled serially via the Profibus. The Profi-RAM Serial ID # should be set as a slave
device to a master polling device.
NOTE: The Serial ID of the Model 700 Gas Sensor connected to the Profi-RAM must be set to
ID = 01 for proper communication between the two devices.
Set Serial ID is used to set the Profibus serial ID address. It is adjustable from 01 to 127 in hexadecimal
format (01-7F hex). The current serial ID can be viewed in View Sensor Status using the instruction given in
Section 3.1 View Sensor Status.
The menu item appears as: “Set Serial ID”
From the “Set Serial ID” text scroll, hold the programming magnet over PGM1 or PGM2 until the “V” prompt
appears and continue to hold the magnet in place for an additional 3-4 seconds (until the display starts to scroll
“Set ID”). The display will then switch to “XX“(where XX is the current ID address). Swipe the magnet
momentarily over PGM2 to increase or PGM1 to decrease the hexadecimal number until the desired ID is
displayed. Hold the magnet over PGM1 or PGM2 for 3-4 seconds to accept the new value. The display will
scroll “ID Saved”, and revert to “Set Serial ID” text scroll.
Move to another menu item by executing a momentary hold, or, return to Normal Operation via automatic
timeout of about 15 seconds (the display will scroll “Set Serial ID” 5 times and then return to Normal
Operation).
3.4 Set-up for Relay Outputs
The user interface allows setting the configuration of the three relay contacts of the RAM. The three relays
can be optionally configured as follows:
Alarm 1: 1) gas level, 2) ascending/descending, 3) latching/non-latching, and 4) energized/non-energized
Alarm 2: 1) gas level, 2) ascending/descending, 3) latching/non-latching, and 4) energized/non-energized
Fault: 1) latching/non-latching and 2) energized/non-energized
The three menu items for relay output set-up are Alarm1 Settings, Alarm2 Settings, and Fault Settings.
They are used to set the gas alarm levels and relay status for ascending/descending, latching/non-latching, and
energized/de-energized. The gas concentration level for alarms can be set between 5-100% of the full-scale
range of the 700 Gas Sensor. The current relay configuration settings can be viewed in View Sensor Status
menu.
The menu item appears as: “Alarm1 Settings”
From the “Alarm1 Settings” text scroll, hold the magnet over PGM1 or PGM2 until the “V” 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. To save the level, hold the magnet over PGM1 or
PGM2 until the LCD scrolls, “Level Saved” (about 3 seconds).
