The transfer is bumpless and will not disturb the process being controlled. All instruments have a basic 8-segment programmer built-in as standard.
This facility must be enabled by the user, as explained in the section, Configuring the Programmer. Many applications need to vary temperature, or process value, with time. Such applications need a controller which varies a setpoint as a function of time.
All programmer models will do this. The setpoint is varied by using a setpoint program. Within each controller there is a software module, called the programmer, which stores one, or more, such programs and drives the setpoint according to the selected program. Page 51 see the final topic in this chapter. When a program ends, the programmer is put into either, a continuous Dwell state with all outputs staying unchanged, or the Reset state.
Table Segment Types Controller This can be disabled in configuration by selecting the PdS output as SP. Use to select the required program number, from 1 to 4. It appears in order to maintain software sync consistency with and controllers. Page 58 [Only appears when Holdback has been selected for the whole program. Press Continued on the next page.
Page 59 1 to By defining the characteristics of each segment of the program, you define the whole program. Set the target setpoint using Press Continued on the next page. Page Pressing will step through all the remaining event outputs. In practice, the has a maximum of three physical outputs, although more than one event can be combined onto a single physical output. See Chapter 6, Configuration. Page Chapter 6 Configuration Configuration is protected by a password and should only be carried out by a qualified person, authorised to do so.
It is the responsibility of the person commissioning the process to ensure that the configuration is correct. You will obtain the first display of configuration.
After a two-second delay, the display will blank then revert to the Home display in Operator level. Page Navigation Diagram Part A to. PV nonE inp. H rmP. U Ltch dtYP H OP bLoc nonE Fig 6. The navigation diagram shows typical parameters, but is dependant upon the exact configuration of the instrument.

Calibrate the controller to suit the characteristics of a particular installation. Remove long term drift in the factory set calibration.
User calibration works by introducing a single point, or two-point, offset onto the factory set calibration. Press continued on the next page Controller Page 82 Li. To protect the calibration against unauthorised adjustment, return to Operator level and make sure that the calibration parameters are hidden. To protect the calibration against unauthorised adjustment return to Operator level and make sure that the calibration parameters are hidden.

Load current monitoring and diagnostics may be used with any time proportioned output, This module must be fitted in module position 1. The load current displayed is the steady state true rms current measured during the ON period. The minimum on times are:- Mode 2 0.
Page To Set The Alarm Trip Levels Any plug in module can be used for alarms provided they are not already being used for another purpose , such as control. Any one or more alarms can be attached to an output, which will operate when an alarm occurs.
Contacts are rated at 2A Vac for operating external beacons or audible devices. Page 93 Press to show output power OUT. H OUT. H To set the max Press output power to to show Page 8. See Chapter 5 Controller The ordering code is in two parts. The hardware coding and an optional configuration coding.
Page PDSIO is a proprietary technique developed by Eurotherm for bi-directional transmission of analogue and digital data between instruments. Mode 1: provides logic heating to a Eurotherm TE10S solid state relay with feedback of a general load fault alarm. Mode 2: provides logic heating to a Eurotherm TE10S solid state relay with feedback of load current and two alarms: solid state relay failure and heater circuit failure. Contact your nearest Eurotherm agent for repair. Caution: Charged capacitors Before removing an instrument from its sleeve, disconnect the supply and wait at least two minutes to allow capacitors to discharge.
