DTM30 TEMP Temperature Module
General Information
The DTM30 is a totally new concept in DIN rail signal conditioning and consists of a family of DIN rail
modules, each one having a high degree of functionality and configurability. They accept all common
signals and have a choice of output options including an isolated (0 or 4 to 20) mA re-transmission
signal, change over trip relay, twin normally open relays or various combinations. For systems that
require more local input, single channel versions with an in-built keypad and digital display are
available where functions can be accessed via the front panel keys.
Each unit comes complete with a RS485 serial communications port which enables DTM30 to be
integrated into a complete process control system. Unit wiring is simplified and speeded up by using
the integral 'power / comms rail' system provided with each unit which removes the need for
complicated and expensive back plane wiring.

Care must be taken when installing units into an enclosure to ensure that the ambient temperature
range is not exceeded. Power supply units can produce heat and if possible are best mounted in a
separate enclosure away from the DTM30 units.

DTM30 is provided with a unique ‘BUS JUMPER’ system for quick wiring of communications and
power connections. To use the Bus Jumper, disconnect all power supply/communications connectors
and place them so that they connect between the two units. Wiring to one connector then connects to
all units.

DTM30 Menu Programming
1. Operating Modes
All single channel DTM30 has 3 operating modes. These are:
• Run Mode – Process Variable is displayed.
• Menu Mode – Enables navigation around menu structure.
• Edit Mode – Enables menu parameters to be edited.
Run mode is the principal mode of operation. The other two modes are accessed as shown in the
following diagram.
2.
Key Press Definitions
Each DTM30 unit has 3 keys (A, B & C) to enable menu programming. Each key pressed
individually produces the following menu action (shaded square signifies key pressed ):

DTM30 TEMP Temperature Module
Keys pressed simultaneously produce the following menu actions (shaded square signifies key
pressed):
A: red key, B: green key, C: blue key.
3. Entering Menu Mode
On power up, the unit(s) will take a few seconds to configure itself. Run mode will then automatically
be entered. Menu mode is accessed from run mode by pressing ENTER followed by CYCLE. The
user will then be able to move around the root menu.
4. Root Menu
5. Navigating Around the Menu
The user can navigate around the root menu (or any sub-menu) by pressing the CYCLE key. Menu
navigation wraps around at the end of the menu list. The items displayed in the menu can either be
submenus, parameter lists or numbers
6. Entering a Sub-Menu
Pressing SHIFT enters the sub-menu or enables parameter list/number editing, depending on
where the menu structure is currently being pointed. If the menu navigation is pointing at a

sub-menu, the subsequent sub-menu can then be cycled around using the CYCLE key.
7. Editing a Parameter List
A parameter is selected from a list of options. The parameter option list can be cycled through by
pressing the INC key. The user will be able to distinguish between a menu cycle action, and a
parameter list cycle action by having the following 2 dynamic display styles:
Action
Display Style
Menu Cycle
Display scrolls on cycle press, no flash
Parameter List Cycle
Flash display at 1Hz
While the display is flashing, the option on the display has not been saved to memory. When the
desired parameter option is in view, pressing the ENTER key will save it to memory. The display will
stop flashing for 1 second to confirm the selection, before returning to the previous sub-menu.
Waiting for 1 minute without a key press, or pressing the ESCAPE key will return the user to the
previous submenu, without saving the selection.
8. Editing a Number
A number is edited by incrementing each digit in turn. The user will know which digit is currently
selected for incrementing by the flashing (@1Hz) of that digit. Pressing the INC key will increment
the digit. On overflow, the digit will wrap around to ‘-‘ or ‘0’, whichever is applicable. Pressing SHIFT
will shift the currently selected digit right one place. If the number is a whole number, pressing
SHIFT when the right most digit is selected will wrap the selection around to the left most digit, and
the process starts again.
While the display is flashing, the number on the display has not been saved to memory. When the
desired number is in view, pressing the ENTER key will save it to memory. The display will stop
flashing for 1 second to confirm the saved number, before returning to the previous sub-menu.
Waiting for 1 minute without a key press, or pressing the ESCAPE key will return the user to the
previous submenu, without saving the number.
9. Menu Structures
This following describes the menu tree structure through the use of a tree-diagram.

range of permit.
DTM30 Default configuration
There is a reset button on the underside of every DTM30 unit, accessible with a small screwdriver
via the lower case vents. In order to reset all configuration settings, this button must be pressed with
power off, then remain pressed for 1 second after power-on. This will reset almost all configuration
settings to their default states, as the following sections show. Any configuration setting not listed
here will be unaffected when performing a reset. A reset is irreversible, and must be performed with
caution.
