1~DESCRIPTION.
The DM650LP loop powered indicator with battery backup accepts a (4 to 20) mA signal
and provides a powerful display interface based on a 6-digit 14-segment LCD display.
User-set scaling is provided to allow the user to set process ranges between -999999
and 999999. Maths functions are provided working on the actual (4 to 20) mA signal for
requirements such as square root extraction.
A 22-segment user-set linearisation/correction function is offered, as well as advanced
messaging, allowing the user to display custom messages for pre-set input ranges.
2~RECEIVING AND UNPACKING.
Please inspect the packaging and instrument thoroughly for any signs of transit
damage. If the instrument has been damaged, please notify your supplier immediately.
3~SPECIFICATION.
Refer to data sheet for full specification.
Configuration
Factory default
(4 to 20) mA = (0 to 100) °C, Relay off
4~ INSTALLATION AND WIRING.
4.1~MECHANICAL.
The instrument is a high accuracy digital (4 to 20) mA loop powered display. In order to
ensure correct operation, the following must be observed:
The product must be stored in a dry clean environment and remain in original
packaging prior to installation.
The instrument must not be installed adjacent to electro-mechanical starters,
controllers, thyristor power units or electrical switch gear.
Any cleaning of the instrument must be done using a mild detergent and soft cloth. No
solvents or abrasive cleaners should be used.
Stated ambient operating conditions must not be exceeded. Battery life will reduce with
higher ambient temperature operating conditions.
4.2~ELECTRICAL.
For a wiring diagram please refer to the rear panel of the DM650LP inside the
case housing.
Screw connectors are used for input and relay connections, allowing the unit to be used
with some in head temperature transmitters (refer to sales for details). On insertion of
battery the unit will run through a power-up check; during this time the relay may
change state.
IMPORTANT: Always remove battery before any wiring takes place. Gain access to the
connectors and battery holder by twisting cap to release front panel assembly from
case.
INPUT: The SEM650LP is to be wired in series on a (4 to 20) mA loop. The battery is
not required for basic display operation, however for datalogging operation the battery
will be required. The connections are marked “+” and “-“.
RELAY CONNECTION: A relay with changeover contacts is available. Screw terminals
are provided for connection for wire size 16 to 20 AWG. The relay contacts are rated at
48 VDC 28 VAC RMS @ 1 A (5 mA minimum current) see DM650LP data sheet.
The relay connections are marked “NO” for normally open, “NC” for normally closed and
“C” for common.
BATTERY: To remove battery, use screwdriver to ease the positive end of the battery
out of holder. Insert new battery negative end first then press into place. (Observe
polarity). Battery type 3.6 V Lithium (2.4 A/Hr) CR14505 (IEC) AA case style. Please
dispose of the battery in a responsible way.
WARNING
For configuring, reading live data or reading logged data if using a grounded loop on the
input, it is important not to connect the programming USB lead to a mains-powered
computer. It is possible to damage the instrument if connected in this way.
To avoid damage, use one of the following methods:
•Disconnect the loop before configuration, reconnect the loop after configuration.
•Ensure any sensor connected and DM650 housing are not in contact with any
conductive parts during configuration.
•Use a laptop-type computer running from its battery power supply, not connected
to a mains supply. This is recommended for reading lived data or offsetting a unit if
already installed in the field.
•Use a USB isolator between the computer and the DM650.
5~USER CONFIGURATION.
IMPORTANT READ COMPLETE SECTION BEFORE ATTEMPTING
CONFIGURATION.
The instrument is provided with a USB interface for direct connection to a PC. Free
software USBSpeedLink is available. Please refer to the USBSpeedLink software for
further information on configuration. The software can be downloaded from
www.status.co.uk.
DISPLAY: The display provides six 14-segment characters for display of temperature
and alpha-numeric messages, together with an 8-segment bar graph and six icons. The
display can operate in an ambient temperature range of (-30 to 70) °C, but at
temperatures lower than -5 °C (due to the slower LCD speed) scrolled messaging is not
practical for screen updates.
The display’s high contrast, coupled with a digit height of 7.9 mm, offers clear readouts
at low as well as high ambient light and direct sunlight.
The display layout is as follows:

5~USER CONFIGURATION (continued).
1. NFC - The Symbol is on when an NFC field is detected. When a detected field is lost the symbol
will turn off after a few seconds.
2. TRANSMIT/RECEIVE: Symbol on when either NFC or USB communication is active.
3. USB: Symbol on when USB port is connected to a PC. Please note battery is not required during
configuration.
4. LOG: Not used
5. mA: On when bar graph is set to display % mA input range, off when bar graph shows % log fill.
6. BAR GRAPH: Indicates the state of the logger. The condition is dependent on the selected logger
mode, either Single or Rolling mode.
Single Mode (Log to the maximum number of logs then stop)
Start of Log Mid Log End of Log (alternating)
Rolling Mode (Log to the maximum number of logs then as each new log is taken the oldest log is
discarded)
Start of Log Mid Log Rolled over Log (max bar toggles)
7. DEG: Degree symbol “°” used to indicate either °C, °F, °R or K on the last digit.
8. DIGITS: Six-digit 14-segment display with – sign, range 9999.9 to -9999.9. Advanced mode offers
two process value-dependent 32-character message options.
9. WARNING ICON: This symbol will toggle on and off to indicate a warning. The warning symbol
will be active either when the sensor signal is out of range or not connected.

MULTI-FUNCTION ALERT LED
The alert LED normal state is off, on alert the LED will emit a intense
white light pulse every 5 seconds. The LED can be programmed to
pulse on any of the following combined events:
Mode Description
No events The LED never operates, extending battery life.
(Factory default setting).
Trip Alert when relay 1 trip is on.
Process In advanced mode only the alert LED can be made to
alert in any one of eight user-set process value bands. Example, to
alert operator when process value is outside a safe operating range.
The function of the alert LED can be further enhanced with the option
of displaying an alert message in advanced display mode.
NFC LOGGER INTERFACE
The NFC interface allows the instrument to communicate with an
Android device using NFC connectivity.
The prime function of the interface is to read logged data from the
device using a free app, which is available for downloading to
Android devices.
The app allows the user to read existing logs, change the log
manifest, start a new log, synchronise the instrument clock and reset
the maximum/minimum/average readings. Logs can run to a fixed
number and stop or continually roll over; up to 5000 log points can
be recorded. The start of the log can be delayed up to one month.
Note: For larger logs the data may take over a minute to fully
download via the NFC interface.
USB LOGGER INTERFACE (connector inside housing)
The USB interface allows the instrument to communicate with a PC
running the USBLogLink software
The prime function of the interface is to read logged data from the
device using free software available to download.
The software allows the user to read existing logs, change the log
manifest, start a new log, synchronise the instrument clock and reset
the maximum/minimum readings.
USBLogLink is available from the manufacturer or supplier.
