1. SAFETY INFORMATION All personnel using this product must carefully read this manual prior to operation. Your attention is drawn to Safety Information Leaflet IM-GCM-10. If
these controllers are handled improperly or not used as specified, the result may: cause danger to the life and limb of the user or a third party. damage to the controller and other items belonging to the owner. hinder the performance of the controller.
1.1 WIRING NOTES Every effort has been made during the design of the controller to ensure the safety of the user, but the following precautions must be followed:
Maintenance personnel must be suitably qualified in working with equipment containing hazardous live voltages. Ensure correct installation. This Controller is designed for installation in an enclosure which provides adequate protection against electric shock. Local regulations regarding electrical installation should be rigidly observed. Consideration should be given to prevention of access to the power terminationís by unauthorised personnel. Safety may be compromised if the installation of the product is not carried out as specified in this manual. Isolate the Controller from the mains supply before opening the unit. The controller is designed as an installation category II product, and is reliant on the building installation for over-current protection and primary isolation. Wiring should be carried out in accordance with IEC 364 or equivalent. Fuse rated at 0.5A/250V should be fitted in all phases of the Controllerís supply. Fuses should not be fitted in the protective earth conductor. The integrity of the installation protective earth system must not be compromised by the disconnection or removal of other equipment. The Mains cable connections at the rear of the controller, must be retained in position (by tie wrapping Etc.). This will prevent the high voltage cables at the rear of the controller from touching the SELV (Safe Extra Low Voltage) connections, in the unlikely event of the terminals coming loose. A disconnecting device (switch or circuit breaker) must be included in the building installation. This must be in close proximity to the equipment and within easy reach of the operator. There must be a 3mm contact separation in all poles. It must be marked as the disconnecting device for the controller. It must not interrupt the protective earth conductor. It must not be incorporated into a mains supply cord. The requirements for the disconnecting device are specified in IEC 947-1 and IEC 947-3 or equivalent. The Controller must not be located in such a way that the disconnecting device is made difficult to operate.

1.2 SAFETY REQUIREMENTS AND ELECTROMAGNETIC COMPATIBILITY NOTES This product is CE marked. It conforms to the council directive 89/336/EEC and the directive 92/31EEC, which modifies the directive 89/336/EEC (Electromagnetic Compatibility) by meeting the standards EN50081-2 (Industrial emission) and EN50082- 2 (Industrial immunity). And the council directives 73/23/EEC (Low Voltage) as amended by article 13 of the directive 93/68/EEC, by meeting the standard EN 61010-1.
This product may be exposed to interference above the limits of EN 50082-1 if:
The product or its wiring is located near a radio transmitter. Excessive electrical noise occurs on the mains supply. Cellular telephones and mobile radios may cause interference if used within approximately three metre of the product or its wiring. The actual separation necessary will vary according to the power of the transmitter. AC power line protectors should be installed if mains supply noise is likely, Protectors can combine filtering , suppression, surge and spike arrestors.

When using SX75 controllers to directly drive VMD electric actuators damage to the controllers internal relays might occur due to switching the relatively heavy electrical loads. Auxiliary relays should therefore always be installed between the controller and the valve drive actuator. This will protect the controller from switching the actuators high current loads, avoid introducing high current loops within the proximity of the controller, and provide an easily replaceable switching element outside of the controller. This advice is in line with that recommended by other manufacturers of similar equipment and is considered to be good working practice.

PARAMETERS DESCRIPTION
Entering parameters
Second group of parameters
The output relay contacts are
When configuration phase is completed, the controller can display all the parameters of functions that may be entered to their desired values. To simplify the exercise the parameters have been divided into three groups . Group 1 covers the parameters related to the set point. Group 2 covers control parameters. The third group, which is protected by the password 1111, are the advanced parameters. These include the security access, the fuzzy control parameters, the parameters for the serial communication, all the limiting functions and safety states functions.
Hy
Hysterisis of relay output Y1 (G = 0) The hysterisis is a zone within which an output does not change and maintains the state previously assumed. In order to obtain a change in the state of variable X it is necessary to go outside this zone. The amplitude of this hysterisis zone is expressed as an amplitude % of the configured scale. The output contacts are to be found between terminals 16 and 17. p.b. Proportional band (G = 1 to 9) The band within which the modulation of the output in direct proportion to the difference between the set point W and the measured value. It is calculated as a % of the input span. t.i. Integral time (G = 1 to 9) This is the time used by a single integral action to repeat the proportional action. This action is expressed in minutes. t.d. Derivative time (G = 1 to 9) This is the time taken for a single proportional action to attain the same level as the P + D output. This action is expressed in minutes. f.int Percentage intensity of fuzzy action (G = 1 to 9). The main control output is composed of the sum of two control algorithms, Fuzzy and PID. This parameter permits the balancing as a % of the proportion of the fuzzy algorithm in relation to that of the PID. With most applications the default value of 50% would be suitable. tc Cycle time of the output Y1 (G = 1,2,6,7) This parameter is expressed in seconds and defines the total time of the On/Off states of the main output Y1 modulated in % of the PID + Fuzzy algorithm. e.g. If Y1 = 20% and t.c. = 30”, the On state = 6” and that of the Off = 24”. If G = 1 or 6, the output relay contacts are between terminals 16 and 17. If G = 2 or 7, the logic output as a voltage is available between the terminals 19(+) and 20(-). tc 2 Cycle time for “cooling output” Y1 (G = 6 to 9 and M = <> 3, <> 6). This parameter is expressed in seconds and defines the total time of the On/Off states of the cold output Y1 modulated in % of algorithm PID + Fuzzy. e.g. If Y = -20% and tc2 = 30”, the On state = 6” and that of the

When one of these set values is recalled the small auxiliary display on the front of the instrument shows the set number recalled. sl. u. Rate of change for increase of the main set point SP. Any new value of the main set point SP greater than that previously entered set point will change at the rate entered into this parameter. The slope is expressed in digits/minute. sl. d.

Any new value of the main set point SP less than that previously entered set point will change at the rate entered into this parameter The slope is expressed in digits/minute. yY2sp Set point of event output Y2 (I = 1 to 8) y2Hy Hysterisis of event output Y2 (I = 1 to 8) Hysterisis is a zone within which an output does not change and maintains the state previously assumed. In order to obtain a change in the state of the measured value X it is necessary to go outside this zone. The amplitude of this hysterisis zone is expressed as an amplitude % of the configured scale.

The dead band between the heating and cooling outputs (G = 6 to 9) If the variable X coincides with the set point sp1 and the output positions itself at 0% the system will tend to pass continually between hot and cold and vice versa. The parameter involved defines that the command at the output of the controller, whether it is hot or cold, will only be forwarded if it is greater than that written in the same parameter.
rcr Relative gain of the “cooling” output (G = 6 to 9). This is a parameter that determines the amplitude of the proportional band of the cold with respect to that of the hot: pbf = pb / rcr pbf = Proportional band output Y1 “cold” pb = Proportional band output Y1 “hot” ty
Time for full valve travel (G = 5) for VMD. This is the time used (expressed in seconds) for the control valve to travel from its lower limit to its upper limit. As a control algorithm of the “floating” type, this parameter is fundamental to a correct positioning of the control valve.
dy
Pressing the A/M button again, the controller stores the “100%” position. At this point the calibration operation is concluded and to terminate press the “> enter” button. During the calibration phase it is useful to time the valve travel time for the ty parameter.
Resolution of positioning or dead zone (G = 5). This parameter expressed in actuator run %, defines the minimum movement required for the servomotor. All the commands given by the control algorithm with lower amplitudes than the value written in the dy parameter, will not be executed.
pot.1 Procedure for calibration of the feedback potentiometer. Only for VMD control (G=5) This calibration is performed if the A/M button is pressed. When the value on the display remains steady the VMD control valve has reached its lower run limit. Pressing the A/M button again, the controller stores the “0%” position and drives the control valve to its maximum position. When the value on the display remains steady the VMD control valve has reached its upper limit.
These four parameters are related to serial communication, they only appear during the setting up phase of the instrument (SX75+ only) and do not relate to the configuration. splI Low limit value for the main set point SP1 splh High limit value for the main set point SP1
Third group of parameters AparSecuity access to parameter groups This function is used to set the level of access allowed for groups 1 and 2. - 0 Group not visible - 1 Group visible, without any facility to modify parameter contents. - 2 Group visible, with facility to modify parameter contents. Atu Auto Tune With this parameter the controllers autotune function can be enabled or disabled. On entering “0” the tuning function is disabled and the “tune” parameter is no longer available in the main menu. f.err Span of fuzzy operational zone (G = 1 to 9) This parameter defines the zone of operation for the fuzzy algorithm and is calculated in % of scale. The optimum value of this zone can be calculated using the following formula : f.err = 4 x p.b. f.der Fuzzy derivative (G = 1 to 9). This parameter defines the speed of the process to be controlled. It is expressed as “ % scale/minute” and its optimum value can be calculated with the formula : f.der = 4 x p.b./t.i. pb = Proportional band expressed as a percentage ti = Integral time expressed in minutes. t.san Sampling time (G = 1 to 9) This parameter determines the sampling time and is variable between 1 and 30 seconds max. The optimum sampling time is relative to the speed of the process to be controlled and is given by : t.san = t.i. x 60 / f.err pb =Proportional band expressed in % of scale ti =Integral time expressed in minutes. This is automatically calculated during auto-tune. sCI Enable or disable serial communications (SX75+ only) Addr Recognition address of serial communication (SX75+ only) sCbr Baud rate of serial communication (SX75+ only) sCpa Parity control of serial communication (SX75 only)

TUNING AUTO-TUNE
For serial comms View instrument SX75+ model only Device number 0 … 63
Auto-tune should be used when the instrument is first installed to provide approximate values for the FUZZY algorithm, and calculation of proportional, integral and derivative parameters. When the auto-tune cycle has been completed, the values for FUZZY (ferr; fder; t.san) will also be adjusted automatically. It is possible to escape from the auto-tune procedure at any time by pressing any key.
