Fax: 01734 750057 Ne ia cree aIR32/DR Industrial Range of Temperature and Process Controllers The IR32 range of controllers has been developed from the highly successful refrigeration thermostats manufactured by Carel in Italy. These controllers have revolutionised the thinking behind temperature and process control. Current developments in this type of instrument have been based on the assumption that industrial applications require ever increasing sophistication in control techniques, giving tight control and rapid response to the most stringent and variable processes. However, the vast majority of applications do not require such complicated and sophisticated techniques. This is not to say that the IR32/DR is not sophisticated; programmable alarm functions, control action, time delays, output sequencing,selectable setpoints, Infra-red remote control and many other features justify such a description for this range of products. The point is that the basic control actions of On/Off and Proportional+Integral are quite sufficient to provide stable control for many applications, with the significant benefit of a price tag of better than 50% of the now common PID, autotuned controllers supplied elsewhere. Another revolutionary concept incorporated in the IR32/DR range is the pre-determined and selectable control actions (Function Modes). Here the user can decide which Control action suits his application, for example; Heat+Cool with Deadband, Direct action plus Alarm or PI mode with selectable setpoints. Simply by selecting 1 of the 9 preset modes, he can dedicate the operation of the IR32/DR to a specific function. Finally, for applications which require multiple controllers, such as supermarkets or building ventilation, it is possible to program the IR32/DR from either a remote, infra-red, hand-held programmer or a PC, via a RS485 communications network.

When pressed for > 5 secs, accesses primary parameters. When pressed simultaneously with SEL key, accesses Function Modes , via code 22. When pressed simultaneously with SEL key, accesses Advanced Parameters, via code 77. Cancels alarm buzzer when activated. Note: this does not reset the alarm conditions. : When momentarily pressed, accesses Set-Point. When pressed simultaneously with PROG key, accesses Function Modes and Advanced Parameters. Once a parameter has been accessed, enables variable adjustment via V and A keys, and acknowledgement of new value. : Allow forward or reverse rotation through program parameters and up or down adjustment of variables. O Reverse : Reverse Action Led. Flashes cyclically for each output activated in Reverse Mode. O Direct 838 : Direct Action Led. Flashes cyclically for each output activated in Direct Mode. : 3 digit, green Led display.

Reverse action mode with adjustable Set-Point (SP) and Hystereris below SP. Reverse action mode with adjustable SP, Hysteresis and Dead-Band (DB). For 2 (W) and 4 (Z) output models, DB is equi-spaced about SP. Proportional (P) action mode with adjustable SP, proportional Band (PB) and DB. As for Mode 3, DB is equi-spaced around SP for W and Z models. A Proportional + Intergral (PI) mode is also available by selecting the correct variable in parameter C5. Alarm Mode, operating as for Mode 3 but with one output dedicated as an alarm signal. For single output (V) models the output is an Alarm, for W models one output is dedicated to a high/low alarm and, for Z models, two outputs are dedicated to high and low alarms respectively. Direct or Reverse action mode, selectable from the digital input (DD. DI open = Direct DI closed = Reverse. Direct action mode with two Set-Points SP1 and SP2, each with its own adjustable Hysteresis and selectable from the digital input. DI open = SP1/HY1 and DI closed = SP2/HY2. Reverse action mode with functions as for Mode 7. Direct plus Reverse action mode (Heat + Cool) with each dedicated to one output (2 for Z models) providing two independant Set-Points. This mode is only available for W and Z models. Error Messages Message Description Cause Solution Er0 Probe error Open or short circuit probe or connection. Check connections and probe.
