1 Introduction
1.1 General
The Data Radiation Meter-3000, is a multiple detector based dose rate meter, capable of
supporting one internal gamma detector and three external detectors by using state-of-the-art
microprocessor-based technology and combined telemetry of the WRM2 900 MHz or 2.4 GHZ
FHSS radio. The DRM-3000 is designed for highly stable and accurate dose rate
measurements from different types of detectors.
The DRM-3000 is a lightweight and compact instrument with sophisticated software offering
special features and optimal performance for telemetry data.
The RMVC Software is used to configure (RMV) and calibrate (RMC) the DRM family of
detectors.
An automatic self-diagnostic procedure continuously checks both electronics and detectors
and reports any case of detector failure.
The DRM may be used in the following ways:
by connecting the meter to a PC
by connecting the meter to a DDC-16/AM-16 Area Meter (wired) or RS-485 cable
by using the internal WRM2 FHSS radio to transmit data
by using an internal or externally connected network adapter
The meter includes four electronic boards:
PCL R1010V4.0 CPU Board- responsible for managing the GUI
PCL R1011V4.0 CPS-MAIN Board – responsible for managing the external detectors
PCL R1020V2.0 CPS-STACK Board – responsible for providing the H.V. to AMP detectors if
required.
PCL R1021V1.0 DC2DC Board – responsible for providing 24VDC if required
PCL R1022 V1.0 Internal W.R Detector – If required
A built-in TCP/IP is the connection used for calibration and configuration. The WRM2 FHSS
radio is already included in the DRM-3000 package and a base station (ROTEMI P/N: WR2-
9001) is needed for reception of telemetry data.
1.2 Field of use
The DRM-3000 has been designed to be mounted in a strategic position providing up to four
radiation levels simultaneously thus providing the users, a comprehensive overview of the
radiological conditions in the work place. Each of the four sections can be programmed to
display the Dose Rate, Accumulated Dose and Detector Name. The background color of each
section reflects the relationship between the dose rate and threshold levels thus providing an
extra input for the user.
The radiation data is stored internally in each meter for a month and can also be exported to
an external Control Station in TCP/IP, POE, 485 or wireless modes.

6 Operation
6.1 Detectors
Each DRM-3000 is capable of supporting one external instrument with a 4-20 mA Output. The
User can set the required Units of Measurement, High (20mA) Range and Low (4mA) Range in
the DRM-3000 using the RMVC software.
The DRM-3000 is also capable of supporting the full range of Rotem Detectors as well as
others like the Ludlum 42-30 Rem Ball Neutron detector, the Ludlum Prescila Neutron Detector
and the SFP-100 Alpha Beta detector from V.F.
Some detectors like the AMP series, which have a minimum amount of electronics in the
detector to preserve their “radiation hardness” need the H.V. to be supplied by the DRM-3000
and other detectors, like the Wide Range Gamma detector, which is a smart detector, are
capable of sending the radiation data to the DRM-3000 via serial data.
The DRM-3000 is designed to interface with all these different types of detectors but care
should to be taken when first connecting the detectors to the DRM-3000
6.1.1 Connecting the Detectors
The placement of detectors in their slots defines the position their data is displayed on the
Screen.
If more than one detector is connected to the DRM-3000 Meter, the Display will be divided
into all four segments and each segment will display according to the connector. For
example if an internal detector is installed and a detector is connected to the Detector 1
connector, then the two top segments will show data and the bottom two segments will stay
blank.

If the radiation field measured by the meter increases significantly, the response time will be
 2 sec. as seen in Table 2. In other cases the response time is according to Table 1.
For example:
For a radiation field increase from 2.5 mR/h to 12 mR/h, the response time will be  2 sec.
For radiation field fluctuations between 2.5 mR/h and 6 mR/h, the response time will be 10 sec.
4.1.1 Automatic Range Switching for the Wide Range Detector
Both the Internal and external detectors include two GM Tubes:
Low range - ZP-1201 (or equivalent), and high range ZP-1301 (or equivalent).
In a field of 0.01 mR/h to 1,500 mR/h both GM tubes are connected and the field is measured
by the low range GM tube. If the radiation field is higher than 1,500 mR/h, the low range
detector is disconnected, and the radiation field is measured by the high range GM tube.
The switching between the low and high range GM-Tube is performed at 1,500 mR/h when the
radiation field increases (low range detector is disconnected), and at 1,000 mR/h when the
radiation field decreases (low range detector is connected).

Page | 14 DRM-3000 Operating Manual
6.3 Power
The DRM-3000 Meter requires between 9VDC to 15VDC 1.5A to operate and is powered by
one of three options mentioned below:
1. AC Power through a power transformer connected to a cable (6.5ft) which connects
externally to the Power Connector shown below
The AC Power Adapter Features
Output; 12 VDC / 2 Amps
Universal Input Range 100~240Vac 50~60 Hz
Safety: UL/CUL/PSE/BSMI/RCM/GS
EMI: CE/FCC Class B: Conduction & Radiation Met.
Protection: OVP (Over Voltage Protection), SCP (Short Circuit Protection), OCP (Over
Current Protection)
2. POE (Power over Ethernet) which uses a standard configuration of 10/100BASE-TX PoE
which is IEEE802.3 af/at compliant.
3. Internal Battery which provides 24 hours operation at background radiation levels.
The DRM-3000 will draw power in the following priority: 1. AC Power, 2. POE and 3.
Internal Battery. This means that if all three are connected the Meter will use the AC Power
only and will not use the POE or internal battery.
The DRM-3000 will charge the internal battery only if connected directly to the AC Power.
The DRM-3000 will be capable of supplying 24VDC through the Auxiliary connector only if
connected directly to the AC Power and if the optional DC power board exists in the
Instrument.

The Aux Connector provides the following inputs and outputs as per the diagram below:
1. Flow Meter
Pin #10 – +24VDC OUT
Pin #11 – Flow Meter Input (4-20mA)
Pin #12 – 24V GND (Power to Flow Meter)
2. 1 x dry contact, N.O. or N.C. dry contact or 24VDC
For meters with CPS firmware version 1.19 and above, once powered up the DRM-3000 will
activate the solenoid to provide the connection shown below. This upgrade provides the user
with an indication on loss of power to the DRM-3000.
The internal solenoid provides a wide switching range from 10 µA 100 mV DC to 4A 250 VAC
but caution should be taken, especially selection of cables, when introducing more than 24VDC
from an external power source being controlled by the Meter.
Upon alarm condition pin #1 and pin #2 are disconnected and pin #2 and pin #4 are connected.
Simultaneously, depending on the selection of the two jumpers 24VDC will be fed to pin #6 (J4
closed) or the second set of contacts will act exactly like the first set of contacts; pin #5 and pin
#3 are disconnected and pin #6 and pin #3 are connected.

Page | 16 DRM-3000 Operating Manual
The DRM-3000 is capable of supplying autonomous 24VDC through the Auxiliary connector only
if connected directly to the AC Power and if the optional DC power board exists in the Instrument.
Additionally the routing of the 24V is defined by the placement of a jumper between pins J4
(behind J3).
If the Jumper is placed on J4 then 24 VDC will be supplied from Pin #5 continuously until an over
threshold condition occurs and then upon an over threshold condition 24 VDC will be supplied to
Pin #6 as long as the over threshold condition continues.
The DRM-3000 is also capable of supplying an external power source up to 10 µA 100 mV DC or
4A 250 VAC without being connected directly to the AC Power and without the DC power board.

6.5 The LAN connector
The external LAN Connector can be used to connect the DRM-3000 to the Ethernet to interface with
a web based software or the LAN connector can be used to connect the DRM-3000 directly to a
computer for the purpose of setting up the instrument, downloading data or uploading new firmware.
To create a clean Ethernet or POE installation, we offer a back cover of the DRM-3000 with a hole
for the Ethernet cable. This way the DRM-300 can be mounted flush to the wall.
6.5.1 The IP address
Each DRM-3000 is provided with a unique MAC address which can be used along with DHCP to set
a static IP. There are two connection options: network connection via DHCP or direct connection to
a PC. In a network connection the Switch is responsible for providing a dynamic IP address and can
be configured to provide a fixed IP address according to the MAC address of each DRM-3000. In a
direct connection the network adapter provides an Automatic Private IP Addressing (APIPA) to the
DRM-3000 each time they are connected and after a period of up to 30 seconds. The range of IP
addresses is 169.254.X.X

6.7.1 Background Colors
The DRM-3000 provides a number of background colors on the display to help users
identify the radiological conditions and reasons for the audible alarms.
Each of the four display segments shows its own individual color, while the external LED
shows the color reflecting the worst case scenario as follows:
Green from background to first threshold
Yellow from first threshold to second threshold
Red from second threshold upwards or User Threshold (Alarm).
Blue Shows a Lost Contact condition between detector and Meter
6.7.2 Confirming an Alarm (TBD)
Clicking on any of the buttons on the Control Panel resets the Alert condition, silences the
buzzer and deactivates the solenoid. The background color remains either yellow or red as
long as the dose rate exceeds any of the thresholds.
The DRM-3000 provides both an audible and visible alarm when the following occurs:
Over threshold condition: There are two internal thresholds for dose rate. The background
color will change from green to yellow if the first dose rate threshold is breached and from
yellow to red if the second dose rate threshold is breached.
User Alarm threshold condition: This internal threshold is set via the RMVC software or
WebiSmarts Software and activates an audible alarm, changes the background color to red
and activates the internal solenoid: Clicking on any of the buttons confirms this alarm and
mutes the audible alarm.
