Page 4: General
1.0 General The unit is a highly accurate and stable digital temperature indicator that accepts all commonly used temperature sensors. The unit can be used "stand alone" or, with the Modbus serial communications module option, as part of a larger system. The case design enables option Modules to be easily installed without the need for dismantling or re-calibration. -
Page 5: Unpacking
1.0 General continued The diagram shows the rear panel positions for all electrical connections. 2.0 Unpacking Please inspect the instrument carefully for any signs of shipping damage. The packaging has been designed to afford maximum protection, however, we cannot guarantee that mishandling will not have damaged the instrument. -

3.0 Installation THIS SECTION FOR USE BY COMPETENT PERSONNEL ONLY 3.1 Safety Information WARNING READ SAFETY INFORMATION BELOW BEFORE INSTALLATION WARNING Hazardous voltages may be present on the terminals the equipment must be installed by suitably qualified personnel and mounted in an enclosure providing protection to at least IP20. ISOLATION The power supply terminals and associated internal circuitry are isolated from all other parts of the equipment in accordance... -
Page 7: Nstalling Into A Panel
3.2 Installing Into a Panel Refer to section 8.0 for Mechanical Detail. The maximum panel thickness is 10mm. The instrument case has an integral gasket which forms a seal when the instrument is tightened against the panel. The panel should be clean, smooth and at least 1.6mm thick for the seal to be effective. WARNING Use only the retaining screws provided to clamp the instrument to the panel ( screws must be tightened sufficiently to effect a... -

3.4 Power Supply Continued Wires are retained by screws. Ensure that the exposed section of the wire is fully inserted and that no loose strands are exposed. 3.5 Sensor Connections All sensor connections are made via a five way "fast wiring" socket at the rear of the unit (wire size 0.5 to 1.5mm 3.5.1 Current Measurement of an Internally Powered Loop A 24V internal power supply is available to power external field transmitters. -

Page 10: Programming Guide
To make a connection: Insert small screwdriver blade into tension clamp orifice, (1) push and twist to deflect clamp into open position. Do not lever screwdriver thus forcing connector body sideways. Insert conductor tail sufficiently into (2) then release screwdriver. Ensure no loose wire strands protrude. -
Page 11: Entering Menu Mode
4.3 Entering Menu Mode The Root Menu mode is accessed from "Run" by pressing ENTER (B&C) followed by CYCLE (A). The display will now show "inPt". In order to understand what this means, the following diagram shows where we are within the basic Root menu. * Slot menus only appear when respective option modules are fitted. -
Page 12: Editing A Parameter
4.3.3 Editing A Parameter The items displayed in the menu can either be submenus, parameters or numbers, most of the items in the Inputs menu are parameters which can be edited. Press the CYCLE (A) key until tYPe is displayed, then press SHIFT (B). The current setting will now be shown flashing. -
Page 13: The Menus
The Root menu, as its name suggests is not a submenu. Pressing the ESCAPE (A&B) key sequence whilst in the Root menu will take the user out of Menu mode and into Run mode. Thus the process variable will be shown on the display. Refer to section 5.2 if an error code is shown after programming in menu mode. -
Page 14: Run Mode Operation
5.0 Operation 5.1 Run Mode Operation The normal display shown in this mode is the process variable. KEYPRESS ACTION CYCLE (A) View setpoints (Adjust value if SPEn enabled) CLEAR (A&C) Clear latched alarms (cLEn enabled) 5.2 Failure Modes If the input is outside the measuring range of the instrument, the following error messages will be shown. -
