CS03Issued 07/01

P/N 412960D

Overview

WARNING: Allow only qualified personnel to perform thefollowing tasks. Observe and follow the safety instructions inthis document and all other related documentation.

The control system may only be used to regulate and control Nordsonunits/systems. The values stated under Specifications in the manual forthe unit/system (temperatures, speeds, etc.) must be complied with.Nordson will grant no warranty and assume no liability for damageresulting from incorrect settings.

Any other use is considered to be unintended. Nordson will assume noliability for personal injury or property damage resulting from unintendeduse.

Intended use includes the observance of Nordson safety regulations.

The control system may not be used under the following conditions:

� In defective condition

� In a potentially explosive atmosphere

� When unauthorized changes or modifications have been made by thecustomer

� By an electrostatically charged person.

Nordson knows of no residual risks.

This manual applies to

� The control system CS 20

� The control system CS 20 with PROFIBUS DP.

Control system CS 202


CS03Issued 07/01

P/N 412960D

When a control system CS 20 without PROFIBUS interface is used, thischapter can be ignored.

For the control system CS 20 with PROFIBUS DP, also refer to separatedocuments Communication Data List and Field Bus Interface PROFIBUSDP.

PROFIBUS DP uses the master-slave access method (Refer to EN 50170). Nordson units on the PROFIBUS are always slaves.

Each unit on the PROFIBUS needs a field bus address for communi-cation purposes. Each address may be assigned only once in the fieldbus. The address of the Nordson unit is set on the motor control panelwith the parameter ADR.

Also refer to Technical Appendix of Motor Part, Field Bus CommunicationModule, PROFIBUS Plug Connectors.

The PROFIBUS interface plug connectors are located on the clear coverof the central module.

With the control system CS 20, the cable screen is linked to protectivegrounding / functional grounding with the plug connector X 22.

Two-wire connection according to EIA-RS 485.Line A (usually green) and line B (usually red) must be the same on theentire bus.

To ensure smooth operation, the field bus must end with an active busterminator (terminating resistors) at the beginning and the end of aPROFIBUS segment.

We recommend attaching both sides of the bus cable screen toprotective grounding / functional grounding. When the potential is not thesame at both ends, an equipotential bonding conductor should be laid.

Installation



CS03Issued 07/01

P/N 412960D

To minimize electromagnetic compatibility disruptions, the lowest possibleBaud rate should be selected. Recommendation: 1500 kBaud.

For additional information, also refer to PROFIBUS Guideline, SetupGuidelines PROFIBUS DP/FMS, published by the PROFIBUSNutzerorganisation e. V. (user organization).

Host

Customer’s higher-order control unit, also called master.

In conjunction with the option PROFIBUS DP, the modes stand alone andremote are available. For information on changing the mode using themode switch, also refer to separate manual/supplement for the unit andto the wiring diagram.

When the mode is changed, activation of the startup protection causes allof the drives to stop.

Stand Alone Mode

Stand alone mode is used mainly to visualize data for maintenance andrepair purposes. The unit is operated just like a unit without PROFIBUS:

� Control access only from control panel and from external controlsignals via an interface

� Parameter input only via control panel

� On the host, all parameters can be displayed but not changed. Thehost can read actual values.

Remote Mode

In remote mode, the host controls the unit:

� Control access only from host

� Parameter input only via host

� On the control panel, all parameters can be displayed but notchanged. Actual values are shown on the control panel.

The startup control with leading channel is only active if a leadingchannel has been selected. It prevents hot melt material from charring inhoses/application heads and the build-up of material expansion pressureduring the initial heating phase. It also helps to save energy.

WARNING: If no leading channel has been selected, the tanktemperature can be set to an unpermissible high value. Thiscan damage O-rings and the allowable temperature of the unitsurfaces may be exceeded. This warning does not apply to hightemperature units!

Factory setting: The factory setting depends on the system model.The channel with the longest initial heating phaseshould be chosen as leading channel.

Setting range: See Technical Appendix of the Temperature Part,Temperature Control Panel Board, DIP Switch S 8

Depending on the display selected, either C (Celsius) or F (Fahrenheit) ofstatus display 8 is lit. When display is in Fahrenheit, the control systemcontinues to use Celsius internally. This may result in up to one degreeFahrenheit being skipped.

When this function is activated (Refer to digital module, selector switch S 1, setting A, inputs), the selected drives are switched from speedcontrol to pressure control. Instead of a speed, a pressure setpoint isdetermined. The setpoint can be entered as a value (manual mode) orset via pilot voltage (automatic mode). The speed required to reach thepressure is calculated internally by the control system.

The parameters PSL, PSH, PSP, PAH, PAL and the display Pcr areavailable for pressure control. For a description of the parameters, referto Display Overview, Parameters and Values for Pressure Control andParameter Overview, Special Function Pressure Control

All entries are made in bar, even when the pressure display is set to psi.

There is a common relay output for underpressure alarm and a commonrelay output for overpressure alarm for all (maximum of six) drives.

The pressure sensor measuring range can be modified with theparameter PRS or with the selector switch on the analog module. If thepressure parameter values are no longer within the permissible(measuring) range after modification, the parameters are returned to thefactory setting.

PAH = Pressure Monitoring for Overpressure (when PressureControlled)

PAL = Pressure Monitoring for Underpressure (when PressureControlled)

Overpressure and underpressure values are differential values.

Pressure monitoring serves to indicate underpressure or overpressure and, if necessary, to stop all motors on overpressure.

PAL = Underpressure: If the pressure value falls below the alarm limit (setpoint minus underpressure value) for more than 10 seconds, PALappears in display 30 (Fig. 1), and the red indication lamp Collective fault lights up (error number 242). If the alarm limit is below 0 bar (e.g.setpoint = 2 bar, PAL = 3 bar), no underpressure alarm can be triggered (Refer to example).

PAH = Overpressure: If the pressure value exceeds the alarm limit (setpoint plus overpressure value) for more than 20 seconds, PAH appearsin display 30 (Fig. 1), and the red indication lamp Collective fault lights up (error number 241). If the alarm limit is exceeded for more than 60 seconds, the motors are all stopped and the green indication lamp Ready for operation goes off (error number 240).

Underpressure and overpressure monitoring can each be deactivated for individual motors by setting the parameter to less than 2 % (displayOFF). The relay outlets indicate No underpressure or No overpressure.

The error indications PAL and PAH can be reset by switching the motors on/off. It is then possible to see which motor set off the pressure alarm.

PrS = Variable Pressure Measuring Range

The variable pressure measuring range serves to adjust special pressure sensors to the control system.

PrS Factory setting: 100 bar Note: Special function; the parameter is only available if the selector switchS 1 of the analog module is in position 5 (see Analog Module)

Setting range: 1 to 680 bar Note: Setting must be carried out for each pressure sensor (in each motorpanel).



)

Note: When double stream pumps are used, pressure sensors with differentmeasuring ranges can be used for each pump stream. The parameter PrScan be set separately for each pressure sensor for this purpose.

Plo = Pressure Monitoring for Underpressure

Phi = Pressure Monitoring for Overpressure

The parameters Plo and Phi are omitted when pressure controlled.

Pressure monitoring serves to indicate underpressure or overpressure and, if necessary, to stop all motors on overpressure.

PLo = Underpressure: If the pressure goes below the underpressure limiting value for longer than 20 seconds, Plo appears in Display 30 (Fig. 1)and the red indication lamp Collective fault lights (error number 242).

Phi = Overpressure: If the pressure exceeds the overpressure limiting value for longer than 20 seconds, Phi appears in display 30 (Fig. 1) andthe red indication lamp Collective fault lights up (error number 241). If the pressure exceeds the overpressure limiting value for more than 60 seconds, all motors are stopped and the green indication lamp Ready for operation is extinguished (error number 240).

The error messages Plo and Phi are deleted by switching the motors off and on. It is then possible to see which motor set off the pressurealarm.

drS = Reverse Speed

drt = Reverse Time

Reverse mode is used for example when the hot melt material is applied through application heads which have no mechanical devices to stopits flow. By reversing the motor (opposite rotation), the hot melt material is sucked out of the nozzle, preventing the hot melt material from drip-ping.

On units with the option reverse mode, the motor rotates in reverse after being switched off (if reverse mode is switched on). The speed display(30) blinks during this period. Reverse mode is only switched on when the value drS is within the setting range (the right decimal point in display30 is lit).

rPU = Adapting Speed to Special Gearbox

The parameter rPU serves to adjust the speed display to the max. gearbox output speed of a special gearbox (all other parameters remain un-changed). For example, if the max. gearbox output speed is 60 min-1, the parameter is set so that the speed display shows also 60 min-1.

rPU Factory setting: 100 min-1 Note: Special function may be activated. See Technical Appendix of theMotor Part Motor Panel Board DIP Switch S 2Setting range: 1.0 to 250 min-1 Motor Part, Motor Panel Board, DIP Switch S 2


r_d = Limiting Value for Speed Alarm

The speed alarm serves to indicate any fluctuations in speed and, if necessary, to switch off all motors or even the unit. With speed alarm, thered indication lamp lights up and r_d appears automatically in display 30. The error can be more exactly determined by activating the ServiceDisplay Error (error numbers 245, 246 and 247 are possible).

Speed alarm is activated by the following fluctuations:

The actual speed deviates from the limiting value r_d for longer than 10 seconds (red indication lamp lights / error number 245). When the ac-tual speed returns within the range of limiting values, the error message is automatically deleted.

The actual speed exceeds the limiting value r_d by a factor of 3 and longer than 12 seconds (motors are stopped / red indication lamp lights /error number 246). The speed alarm must be deleted. If the motors were not immediately stopped but rotate for another 6 seconds, the maincontactor drops (unit is switched off / error number 247). The speed alarm must be deleted.

To delete speed alarm: Switch off all motors.

NOTE: Special function. Only with PROFIBUS DP. The selector switchS 1 of the analog module is set to position 8.

NOTE: The four level signals are connected to the PROFIBUS interfacedirectly, without evaluation.

The first three inputs of the analog module are not switched with analogsignals; they are switched with relay outputs. The levels are 0 VDC or 24 VDC. The protective switching of the analog inputs internally limits thevoltage to 10 VDC.

As a switching threshold for recognizing the input state, voltages higherthan 5 VDC are considered high levels and voltages lower than 5 VDC areconsidered low.

If unpermitted combinations of input levels occur, the collective faultindication is activated. The drives are not forced to stop. Error number 67is displayed as the error indication.

The motor speed is aligned on the motor module.

Alignment was carried out at the factory. Setting or alignment is onlynecessary after replacement of modules/boards or if alignment elementshave been mistakenly adjusted.

If the speed at which the motor is normally operated during production(production speed) is known, the speed should not be aligned at 80 min-1

but at the production speed.

1. Set operating mode of the motor to manual mode (illuminated symbolmanual mode must be lit).

2. Note the set motor speed (manual mode).

3. Set motor speed to 80 min-1 or the production speed.

4. Switch on the motor.

5. Set the motor speed to 80 min-1 or to the production speed with thepotentiometer R8.

6. Set the motor speed back to the original value (step 2).
