The DM3600 is configured using the three keys on the front panel. The unit has two modes of operation:
The first is ‘Run’ mode. This will automatically be entered 5 s after power up. This is the principle mode
of operation. There are 6 possible key press combinations, as shown in the ‘Key Press Definitions’ diagram
below. The ‘Run Mode Options’ diagram shows the key presses required to access various states from the
run mode. (See diagram in Section 8.2 overleaf).
The other principle mode of operation is ‘Menu Mode’. The menu navigation method is shown diagrammatically
in the ‘General Menu Structure’ (see Section 9.1).
Once the menu mode has been accessed, the user can use the large ‘Menu Map’ (see Section 10.0) to
navigate through the menu structure.
All programming is done using the three front panel keys, A, B and C.
ESCAPE (A & B), ENTER (B & C) and CLEAR (A & C) are obtained by simultaneously pressing the two keys.
CYCLE (A), SHIFT (B) and INC (C) keys are pressed singularly.

The diagram below describes how to move around the menu structure and enter data. More specifically it
details:
1. How to enter a real number
2. How to choose an option from a list
3. How to enter and navigate around a submenu
Using these three procedures the user can enter all applicable data to configure the unit to suit the application.
The options displayed depends on whether the short menu or full menu option is enabled (This can be
selected in the SYStEn submenu).
This menu configures the unit to suit the application. The menu covered in this section is the menu structure
for all applications.
The ‘Menu’ mode is protected by a passcode and the user is asked for this when the ‘Menu’ mode is
accessed from the run mode. The passcode is set to the default of 0 and can be changed to any value
between 0 and 65535, setting the value to zero (default) removes the passcode prompt and the passcode
function is disabled.

TYPE
This allows the type of input on the unit to be selected. The DM3600 accepts a Voltage, RTD, Thermocouple
or Current Input.
RANGE
Depending on the input type selected the DM3600 will either show the voltage ranges or current ranges
available. Select the range which is applicable to the input device.
LINEARISATION TYPE
The input type selected will determine the linearisation options available. Current/Voltage, RTD or
Thermocouple.
USER LINEARISATION
When the user selects user linearisation, up to 60 co-ordinate pairs of interpolation data can be entered
via the front panel keys. The ‘SE9ntS’ value defines the number of segments.
= Number of interpolated segments = Number of co-ordinate pairs -1
= Electrical input co-ordinate 1
= Process variable (PV) co-ordinate 1
= Electrical input co-ordinate 2
= PV co-ordinate 2
etc......
For n segments there are n + 1 co-ordinate pairs.
If the electrical input goes below electrical input co-ordinate 1, or above electrical input co-ordinate
(n+1), the input is flagged as being under or over-range, respectively.
TEMPERATURE UNITS
This is only available if a Thermocouple or RTD input is selected.
DECIMAL PLACES
The number of decimal places shown on the display can be selected using this option.
INPUT SCALING FUNCTIONALLY
The primary function of a DM3600 is to take an electrical input, and convert it to a displayable Process
Variable (PV, also referred to as an engineering value, e.g. temperature or flow). The DM3600 input signal
can be scaled in one of many ways. For ‘rtd’ or ‘tC’ inputs, the user is simply required to choose the
‘tyPE’ and ‘Lin’ (linearity type). For ‘CurEnt’ or ‘uOLt’ input types, the user can choose STndrd or
AUtO scaling (from the ‘ScALE’ sub-menu).
ENGINEERING LOW / HIGH
If ‘Stndrd’ scaling is chosen, the user will encounter ‘En9LO’ and ‘En9HI’ entries, in order to manually
scale the input to the relevant input_lo and input_hi values (see table overleaf for input_lo/hi values). The
PV_lo & PV_hi values shown overleaf equate to the ‘En9LO’ and ‘En9Hi’ entries). Scaling is subsequently
applied according to the graph overleaf. (The straight line illustrated overleaf will change if a non linear
linearity type is selected. If the user requires strict control over out of range limits, user linearisation
should be chosen).
12.1 INPUT MENU BLOCKS
SE9ntS
In1
OUt1
In2
OUt2
APPLY AUTO SCALE
If ‘AUtO’ scaling is selected, the ‘APPLy’ submenu appears (in place of ‘En9LO’ and ‘En9HI’ entries). The
‘APPLy’ submenu procedure must be carried out as follows.
1. Shift into ‘APPLy’ submenu.
2. Edit & Enter the ‘LOuAL’ engineering value required for low scaling (This will equate to PV_lo).
3. The display will flash ‘APLLO’ to prompt the user to apply the electrical signal corresponding to PV_lo.
If the electrical signal goes out of range, the display signifies this, and the input signal won't be accepted
by the DM3600. This applied electrical signal equates to input_lo, in the graph and table below.
4. Repeat Steps 2 & 3 for ‘HIuAL’, and the corresponding high electrical/engineering values.
OUT OF RANGE ALARM
When an input goes out of range, the following occurs:
If fitted, any relays go into alarm state
If fitted, the re-transmission current derived from the out of range alarm input goes to 3.8 mA or
21.12 mA, depending on whether the burnout setting is set to low or high, respectively.
Once scaling is complete, and the menu structure is exited, if the electrical input is under/over range,
the display shows or

FILTER
The user can choose one of three filter types by editing this configuration;
1. Entering a value of > 0.3. A fixed first order recursive filter is applied to the input processing, with a
time constant (TC) equating to the actual value entered, in seconds.
2. Entering a value = 0.0. An adaptive first order recursive filter is applied to the input processing, with
the time constant adapting to the dynamic behaviour of the input signal.
3. Entering a value x, where 0 < x < 0.3. No filter is applied to the input processing.
BURNOUT
This defines whether, in the event of a sensor failure (burnout), the output current goes high (21.5 mA) or
low (3.6 mA). This is only available if the thermocouple or RTD input type is chosen.

RELAY SENSE
The ‘Inurt’ setting refers to the relay sense during powered operation. All other relay output menu settings
refer to the alarm state. When in alarm, the relevant front panel LED is lit.
DEVIATION
If the ‘dEu’ action is chosen in the alarm action option, this value determines the amount by which the
PV may change before the alarm is triggered. The value should be in the engineering units.
This menu is only displayed if a current re-transmission output pod is fitted. If ‘PrESEt’ is chosen, the output
current can be edited in ‘LEuEL’. Otherwise, the re-transmitted current is derived linearly from the
process variable, using ‘rEtLO’ and ‘rEtHI’.
RE-TRANSMISSION OUTPUT TYPE
The re-transmission can be set to represent rate or total.
OUTPUT SPAN
(4 to 20) mA, (0 to 20) mA or (0 to 10) mA can be selected as the span of the re-transmission.
RE-TRANSMISSION SCALE LOW / HIGH
By entering these values, the user can scale the mA output (selected in SPAn) to the PV. Default values
will be equal to the engineering low and engineering high values entered in the input menu.
PRESET mA OUTPUT LEVEL
This is only available if ‘PrESEt’ output is chosen.
The relay menu shown is for alarm A. There are two alarms A and B so the menu will be duplicated for
alarm B. The relay menu will only be displayed if a twin relay pod is fitted to the DM3600.
SETPOINT A
The setpoint value defines the engineering value associated with an alarm. For example if an alarm is
required when the flow exceeds 10 000 kg/h, the setpoint will be set to 10 000.
ALARM ACTION
This defines the behaviour of the alarm when the setpoint is reached.
HYSTERISIS
The hysterisis value is the difference between the points at which the alarm triggers and releases,
expressed in the relevant engineering units.
ALARM DELAY
The alarm will not trigger until the PV has been in the alarm region for more than the specified number
of seconds.
LATCH
When latch is enabled, an alarm will remain triggered until it is manually cleared.

13.3 RE-TRANSMISSION (mA) OUTPUT MENU
Page 20Page 19

The system menu allows the communications to and from the device to be configured and also allows
various functions to be enabled from the run mode. The passcode can also be changed from within this
menu. (See menu below).
14.0 SYSTEM MENU
MODBUS DEVICE ADDRESS
This sets the address for the RS485 communications. The default is 1 and the maximum is 247.
NUMBER OF WIRES
This defines the type of RS485 communication mode. It can either be 4 (full duplex) or 2 (half duplex).
BAUD RATE
This defines the comms baud rate i.e. the speed of communication between the unit and interrogating
device. The Baud rate is displayed in bps.
MENU TYPE
When ‘SHort’ type is chosen, access to the greyed out menu items is restricted. To allow access to these
items the ‘FULL’ menu type should be chosen.
START UP DELAY TIME
The outputs of the unit will not operate until the start up delay time (measured in seconds) has expired.
The minimum delay is 5 s and the maximum 3 600 s.
DISCRETE ACTIVE LEVEL SELECT
The function of the discrete input ‘dISc’ is to operate as a remote clear button press, i.e. you can use this
to reset the totals remotely. This menu item selects whether the clear function is executed when the
discrete is high (24 V) ‘ACtHI’ or low (0 V) ‘ACtLO’.
MENU ACCESS PASSCODE
When accessing the menus from ‘Run’ mode, the user is prompted for this passcode. If it is zero (default),
then there is no prompt and the password function is disabled. If the password is forgotten please contact
your supplier.
USER OFFSET
This value is used to offset the scaled process variable by a fixed amount.
MENU TIME OUT
This sets the amount of time after which the display will revert to the ’Run’ mode if no key is pressed.
ENABLE
Enables the following sub-menu:
CLEAR LATCH
When set to ‘On’ latched alarms can be cleared by pressing the clear button on the front panel, or
applying discrete input 1.
CLEAR TOTAL
When set to ‘On’, the total is reset by pressing the clear button on the front panel.
EDIT SETPOINTS
When set to ‘On’ the edit setpoints submenu can be accessed directly from the ‘Run’ mode.
