4 Operation overview 4.1 Switching on (page 22) 4.2 Normal operation (page 22) 4.3 Front Panel Controls (page 23) Status All (page 23) Status Max (page 24) Settings (page 25) Narda 4.4 NBM-580 remote protocol (page 32) 4.5 Remote commands and instructions (page 34) 4.6 Commands (page 38) 4.7 Error codes (page 44) 4.
4 Operation overview 4.1 Switching on In order to simplify the turn on procedure it is recommended that the sensors (such as NBM meters and probes) be connected to the NBM-580 and be operating before turning on the NBM-580. The AC input filter has a master power switch located on the back of the NBM-580. That needs to be in the operation position (I) in order for the front panel switch to be able to turn the NBM-580 ON.
4.2 Normal operation 1) Area Monitoring – The NBM-580 acts as a central alarm point for up to 8 field sensors. The NBM-580 can be set to follow sensor alarm levels or set to alarm under local control. This central capability allows it to communicate status virtually anywhere internet connections exist. Narda has various field sensors that can be interfaced depending on what needs to be measured. Nardalert S3 monitors can be supplied with various sensors and configurations for indoor or outdoor uses.
4 Operation overview If only 4 inputs are in use or you choose to lock the display to show only four inputs the display looks like the picture below. If detected levels create an Alarm 1 situation the font and display section for that particular monitor will change from green (normal) to red (Alarm 1).
4.3 Front Panel Controls Settings The Settings key has four sub-categories, Field Meters, NBM-580, Options and Logging. Field Meters Field meters displays information about the sensors that are attached to the NBM-580. Information such as serial numbers of field meters and probes (likewise NS3 mainframes and sensors) as well as frequency range and calibration information are displayed as well.
4 Operation overview GPIB settings button allows you to view and/or modify the GPIB address and, like the Network settings, are more easily set using the external keyboard. Options Options tab displays information and customization parameters such as setting a delay time for the alarm relay, changing the sensor that the analog outputs are representative of, setting time and date, measurement profiles and choosing display modes.
4.3 Front panel controls Alarm 1 Relay – This sets the delay time in seconds from the time the unit alarms to the time the relay activates. Analog – Meter Chan – This sets the analog output(s) to a specific sensor. The analog voltage will vary from 0 to -4.096 VDC, representing 0 to 100% of the sensors dynamic range. Set Time/Date – Allows setting of time and numerical system to common local formats.
4 Operation overview Display Mode – This sets how the connected sensors are displayed on the front panel. In the “Auto” mode, the front panel will display inputs 1 through 4 if sensors are connected to only inputs 1 through 4. If more than 4 sensors are connected OR sensors are connected in both 1-4 and 5-8 channels, the NBM-580 will display 8 channels screen.
4.3 Front panel controls Logging Pressing the “Logging” tab displays the following screen. Logging can be in one of three major modes; immediate, conditional or time based. As shown below in “time based”, you can set the duration that begins immediately or at a certain time. Conditional logging allows the system to only log when set conditions are true. In the example below, 5 channels are active. Channel 1 is set to log readings without any threshold level required.
4 Operation overview Pressing the Set button brings up the window below where the user can choose the type of conditional logging the user wants to employ. You can log all readings that are between the minimum and maximum values set, or log only the first reading between the minimum and maximum and the last reading before the value is outside the minimum and maximum values.
4.3 Front panel controls File Export – File Export is used to export files to an external USB device. User can choose from the Channel (sensor) and tables for each sensor, what data they wish to download.
4 Operation overview 4.4 NBM-580 remote protocol This document is based on NBM-580 firmware Version 2.0.2 and was tested on computers running Windows XP. Telnet connection A Telnet Client can be used to connect to the NBM-580’s LAN port through a TCP/IP socket, port number 3001. Hyperterminal is one example of a Telnet Client.
