2132 and 2116 PID Temperature Controllers Thank you for choosing the 2132 or 2116 Temperature Controller. Supplied in 1/32 and 1/16 DIN panel sizes they are designed for accurate, stable control of ovens, chillers, sterilisers and other heating and cooling processes. Two outputs are configurable for heating, cooling and alarms. The controller is supplied configured according to the order code given in section 5. Check this on the side labels to determine the configuration of your particular controller. 1.

This will give the operator quick access to them by simply pressing the Repeat the above procedure for all the parameters you wish to hide, promote, or make read-only then return to operator level: button. This feature, used in combination with ‘hide’ and ‘ read only’, allows you to organise the way in which you want your controller formatted.
3.11 In reset To Use The Timer Press until you reach the SP list • Press until you reach the tM.OP parameter • or to select the timer operating Press mode, Opt.1 to Opt.5 as follows: • In reset, you can switch between automatic control and standby mode, using the parameter m-A in the HOME list. The controller is supplied with the m-A parameter hidden. You must first reveal it. See ‘To Hide, Reveal and Promote Parameters’. 3.11.1 Opt.
‘Automatic control’ means control at setpoint, with heating (and cooling) being applied. ‘Standby mode’ means: the controller is in manual with zero output power. See ‘Warning!’ in section 3.5. During Running The controller will always switch to automatic control. Heating (or cooling) will be applied and the temperature will rise (or cool) to the setpoint. When the temperature is within 1oC of setpoint, the timer will start counting down.

3.11.5 Opt.5 Mode 5, Delayed Switch On Temperature Setpoint Reset Indefinite dwell at setpoint Timing Reset This mode applies a time delay before turning on the heating (or cooling). When the timer is started, the controller will always switch to standby mode and start counting down. When the timer has timed out, the controller will switch into automatic control, apply heating (or cooling) and control indefinitely at the setpoint. Part Number HA026270 Issue 5.0 Aug 07 3.11.
3.12 To Start And Reset The Timer There are two methods: TIP: Promote tmr to the HOME list for quick access, as described in ‘To Hide, Revealing and Promote Parameters. Method 1.

(0 to 9999). to return to the HOME display As soon as a value is entered into tmr timing will commence.
Method 2. Use this method if you want to set a fixed time and use the stat parameter to start and stop the timer. Press sp to reach the SP List heading. Press until you reach dwel 1234 dwel The stat parameter can also be switched between Off and run by configuring the logic I/O as a Off/run contact closure input. Open the external contact to select run. This is an edge triggered action. Close the contact to select Off. Off is forced whenever the contact is closed.

4.1.3 Alarm Configuration The AL list configures the three internal ‘soft’ alarms and causes the appropriate alarm message to be flashed in the HOME display. At this stage the alarm is indication only (known as a ‘soft alarm’). To make the alarms operate the relay or logic outputs, follow the instructions under “Relay and Logic input/output Configuration.

Note 2: If tmg.3 and tmG.4 are selected, they illuminate the logic or relay output beacons, OP1 and OP2, without operating the actual output. They are used to indicate that timing is in progress while leaving the actual outputs to be operated by the other digital functions such as the END condition which can be used to operate an external klaxen. 6.

4.2 User Calibration Your controller has been calibrated for life against known reference sources. User calibration allows you to apply offsets to compensate for sensor and other system errors. The parameter OFS in the IP list applies a fixed offset over the whole display range. You may also apply a 2-point calibration as follows: • Press until you reach the iP list • Press until you reach the CAL.P parameter • or to enter the password. The Press factory default is 3.
4.3 Automatic Tuning In PID control, the output from the controller is the sum of three terms: Proportional, Integral and Derivative. These three terms deliver just the right amount of power to hold the temperature at setpoint without oscillation. For stable control, the PID values must be ‘tuned’ to the characteristics of the process being controlled. In the 2132 and 2116 this is done automatically using advanced tuning techniques.
If the process cannot tolerate 100% heating or cooling during tuning, the power can be restricted by the heating and cooling limits in the Output list. However, the measured value must oscillate to some degree for the tuner to determine values. Tuning is normally performed only once during the initial commissioning of the process. However, if the process under control subsequently becomes unstable (because its characteristics have changed), you can retune again at any time.
4.3.3 Typical automatic tuning cycle Temperature 1. 2. 3. 4. Time 4.3.4 Calculation of the cutback values When low cutback or high cutback is set to ‘AuTo’ their values will be fixed at three times the proportional band, and will not be altered during automatic tuning. If set to any other value, they will be calculated as part of the tuning process. 4.4 Manual Tuning If for any reason automatic tuning gives unsatisfactory results, you can manually tune the controller. Proceed as follows: 5.
4.4.1 Setting the cutback values Temperature The above procedure sets up the parameters for optimum steady state control. If unacceptable levels of overshoot or undershoot occur during start-up or for large step changes in temperature, then manually set the cutback parameters Lcb and Hcb. Proceed as follows: 1. Set the low and high cutback settings to 3 x the proportional band (that is to say, Lcb = Hcb = 3 x PB). 2.

7. Safety and EMC Information This controller is intended for industrial temperature and process control applications when it will meet the requirements of the European Directives on Safety and EMC. Use in other applications, or failure to observe the installation instructions of this handbook may impair safety or EMC. The installer must ensure the safety and EMC of any particular installation.
precaution may damage the indicator or cause some discomfort to the user. Electrostatic discharge precautions When the controller is removed from its sleeve, it is vulnerable to damage by electrostatic discharge from someone handling the controller. To avoid this, before handling the unplugged controller discharge yourself to ground. Cleaning Do not use water or water based products to clean labels or they will become illegible. Isopropyl alcohol may be used to clean labels.
IEE wiring regulations (BS7671) and in USA use NEC Class 1 wiring methods. Power Isolation The installation must include a power isolating switch or circuit breaker. This device should be in close proximity to the controller, within easy reach of the operator and marked as the disconnecting device for the instrument.
Reasons why the heating might remain constantly on include: • the temperature sensor becoming detached from the process • thermocouple wiring becoming short circuit; • the controller failing with its heating output constantly on • an external valve or contactor sticking in the heating condition • The controller setpoint too high Where damage or injury is possible, we recommend fitting a separate over-temperature protection unit, with an independent temperature sensor, which will isolate the heating circuit.
