-DIN, 81 -DIN & 16 -DIN TEMPERATURE CONTROLLERS 1 4 Product Manual 59125-3
PREFACE This manual comprises two volumes: Volume 1: This supports normal operation of the 41-DIN, 18-DIN and 161 -DIN Temperature Controllers. In normal operation, all actions taken by the user are to be in front of the panel. Volume 2: This supports the installation, commissioning and configuring of the 41-DIN, 18-DIN and 161 -DIN Temperature Controllers. It is intended for use only by personnel who are trained, equipped and authorised to carry out these functions.
59125 1 4 1 -DIN, 18 -DIN & 16 -DIN TEMPERATURE CONTROLLERS PRODUCT MANUAL VOLUME 1 OPERATING INSTRUCTIONS In normal operation, the operator must not remove the Controller from its housing or have unrestricted access to the rear terminals, as this would provide potential contact with hazardous live parts. Installation and configuration must be undertaken by technically-competent servicing personnel. This is covered in Volume 2 of this manual. Contents - Volume 1 1 OPERATOR MODE 1-1 1.

9125 1 1.1 OPERATOR MODE INTRODUCTION This Section covers the routine operation of the Controller, once it has been installed and configured as described in Volume 2 of this manual. The Controller front panel indicators and keys are shown in Figure 1-1.
59125 1.2 DISPLAYS AVAILABLE After the Controller has performed its power-up self-test (during which, if the Function key is held down during power-up, the current Controller firmware revision is displayed), the initial displays appear. The available displays are dependent upon (a) whether the Controller has been configured for Single Setpoint operation or Dual Setpoint operation and (b) the setting of the Setpoint Strategy parameter in Set Up Mode. 1.2.
59125 1.2.2 Dual Setpoint Operation In dual setpoint operation, the available displays are: 1.3 ADJUSTING THE SETPOINT/SETPOINT RAMP RATE The setpoint/setpoint ramp rate (whichever is selected - see previously) may be adjusted using the Raise/Lower keys. The ramp rate may be adkusted in the range 1 to 9999. Any attempt to increase the ramp rate value beyond 9999 will cause the upper display to go blank and setpoint ramping to be switched OFF.
59125 Figure 1-2 1.5 Alarm Status Display OVER-RANGE/UNDER-RANGE DISPLAYS The upper display will indicate if the process variable is higher than the input scale maximum limit (over-range), or lower than the input scale minimum limit (under-range) as shown on the right. 1.6 SENSOR BREAK INDICATION If a break is detected in the sensor circuit, the upper display shows: The reaction of the outputs and alarms to a detected sensor break is dependent upon the input type and is defined in Appendix A. 1.
59125 1.8 PRE-TUNE FACILITY This facility may be used to set the Controller’s PID parameters to values which are approximately correct, in order to provide a base from which the Self-Tune facility may subsequently optimise tuning. Pre-Tune may be engaged (and subsequently dis-engaged) as follows: NOTE: The Pre-Tune facility will not engage if (a) the setpoint is currently ramping, (b) the process variable is within 5% of input span of the setpoint, or (c) an erroneous key sequence is used.
59125 Since Pre-Tune is a single-shot operation, it will automatically dis-engage itself once the operation is complete. 1.9 SELF-TUNE FACILITY This facility is be used to optimise tuning whilst the Controller is operating.
59125 1.10 VIEWING THE HARDWARE DEFINITION CODE Figure 1-3 Viewing the Hardware Definition Code NOTE: An automatic return is made to the normal Operator display after 30 seconds.
59125 2 2.1 SET UP MODE ENTRY INTO SET UP MODE See Figure 2-1.
59125 NOTE: If, on entry into Set Up Mode, the upper display initially shows all decimal point positions illuminated), this indicates that one or more of the critical configuration parameters - typically input range or output use/type - have been altered in value/setting and, as a consequence, all Set Up Mode parameters have been automatically set to their default values/settings. To clear this display, simply alter the value/setting of any Set Up Mode parameter (see below). 2.

59125 2.2.3 Output Power 1 This parameter is the current Output 1 power level. It is a “Read Only” parameter and is not adjustable. 2.2.4 Output Power 2 This parameter is the current Output 2 power level (if Output 2 is fitted). It is a “Read Only” parameter and is not adjustable. If Output 2 is not fitted, this parameter display is not applicable. 2.2.
59125 Figure 2-2 O054-2 Proportional Band and Deadband/Overlap 2-6
59125 2.2.10 Bias (Manual Reset) This bias to the output power is expressed as a percentage of output power. This parameter is not applicable if Proportional Band 1 = 0. 2.2.11 ON/OFF Differential This is a switching differential used when one or both outputs have been set to ON/OFF control (i.e. Proportional Band 1 or Proportional Band 2 or both = 0). 2.2.12 Setpoint High Limit This is the maximum limit for setpoint adjustment.
59125 2.2.16 Output 1 Power Limit This parameter is used to limit the power level of Output 1 and may be used to protect the process being controlled. If no protection is required, this parameter may be set to 100%. IThis parameter is not applicable if Proportional Band 1 is set to 0. 2.2.17 Output 1 Cycle Time The cycle time value required is dependent upon the process being controlled and the type of output being used for Output 1.
59125 Figure 2-3 2-9 Alarm Operation O054-2
59125 2.2.22 Deviation (High/Low) Alarm 1 Value This parameter, applicable only if Alarm 1 is selected to be a Deviation High/Low Alarm, defines a value above (positive value - Deviation High alarm) or below (negative value - Deviation Low alarm) the setpoint; if the process variable deviates from the setpoint by a margin greater than that defined by this parameter, Alarm 1 goes active. The operation of Deviation Alarms is illustrated in Figure 2-3. 2.2.
59125 if the saturated output has not caused the process variable to be corrected by a pre-determined amount V after a time T has elapsed, the Loop Alarm goes active. Subsequently, the Loop Alarm facility repeatedly checks the process variable and the control output(s). When the process variable starts to change value in the correct sense or when the saturated output comes out of saturation, the Loop Alarm is de-activated.
59125 2.2.30 Scale Range Maximum This parameter, applicable only if a linear input is fitted, defines the scaled input value when the process variable input hardware is at its maximum value. This parameter can be set to a value less than (but not equal to) Scale Range Minimum, in which case the sense of the input is reversed. Decimal point position is defined by the Scale Range Decimal Point parameter (see Subsection 2.2.29). 2.2.
59125 2.3 OPERATOR MODE DISPLAYS Once the complete cycle of Set Up Mode parameters has been displayed, the user may then step through the Operator Mode displays (see Subsection 1.2), making adjustments where required, before re-starting the Set Up Mode parameter cycle, as shown in Table 2-1. 2.4 2.4.
59125 Figure 2-4 2.4.2 Manual Tuning Parameters - Output 1 only Controllers Fitted with Output 1 and Output 2 Before starting to tune the Controller to the load, check that the Setpoint High and Low Limits (SPhi and SPLo) are set to safe levels - see Subsections 2.2.12 and 2.2.13. The following simple technique may be used to determine values for proportional band (Pb1), derivative time constant (rAtE) and integral time constant (rSEt).
59125 2.6 EXIT FROM SET UP MODE To leave Set Up Mode, select the initial Operator Mode display (normally process variable) then depress the Raise and Function keys simultaneously, whereupon the Controller will return to Operator Mode. NOTE: An automatic return to Operator mode will be executed if there is no key activity in Set Up Mode for two minutes.
59125 3 RS485 SERIAL COMMUNICATIONS The Controller may be equipped with a two-wire RS485-compatible serial communications facility, by which means communication may occur between the Controller and a master device (e.g. a computer or terminal). 3.1 COMMUNICATIONS ENABLE/DISABLE When Communications are enabled (in Set Up Mode - see Subsection 2.2.36), the Controller parameters may be adjusted by the master device via the serial communications link.
59125 3.2.3 Communications Protocol The protocol assumes half duplex communications. All communication is initiated by the master device. The master sends a command or query to the addressed slave and the slave replies with an acknowledgement of the command or the reply to the query.
59125 3.2.4 Type 1 Message L {N} ? ? * This message is used by the master device to determine whether the addressed slave Controller is active. The reply from the slave Controller, if it is active, is L {N} ?

59125 1 INSTALLATION 1.1 UNPACKING 1. Remove the Controller from its packing. The Controller is supplied with a panel gasket and push-fit fixing strap. Retain the packing for future use, should it be necessary to transport the Controller to a different site or to return it to the supplier for repair/testing. 2. Examine the delivered items for damage or deficiencies. If any is found, notify the carrier immediately. 1.
59125 Figure 1-2 Main Dimensions The procedure to panel-mount the Controller is shown in Figure 1-3. CAUTION: Do not remove the panel gasket, as this may result in inadequate clamping of the instrument in the panel. NOTE: The mounting clamp tongues may engage the ratchets either on the sides of the Controller housing or on the top/bottom faces of the Controller housing. Therefore, when installing several Controllers side-by-side in one cut-out, use the ratchets on the top/bottom faces.
59125 Figure 1-3 Panel-Mounting the Limit Controller Once the Controller is installed in its mounting panel, it may be subsequently removed from its housing, if necessary, as described in Subsection 2.1.
59125 1.3 CONNECTIONS AND WIRING The rear terminal connections are illustrated in Figure 1-4 ( 41-DIN and 18-DIN controllers) and Figure 1-5 (161 -DIN controllers).
