WARNING: Allow only qualified personnel to perform the

following tasks. Observe and follow the safety instructions in this document and all other related documentation.

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

Any other use is considered to be unintended. Nordson will assume no liability for personal injury or property damage resulting from unintended use.

Intended use includes the observance of Nordson safety regulations.

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

Field Bus Interface PROFIBUS

DP.

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 communication purposes. Each address may be assigned only once in the field bus. The address of the Nordson unit is set on the motor control panel with the parameter

Also refer to

Module, PROFIBUS Plug Connectors

ADR

Technical Appendix of Motor Part, Field Bus Communication

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

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

Installation

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

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

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

A pressure sensor can be installed for each pump stream. The control system offers the option of displaying both pump stream pressures. There are two display lines for each motor on the motor control panel (Fig. 3). In the second line of each display, the pressure of the second pump stream and all parameters relevant for this pump stream are shown.

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

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

Factory setting:

The factory setting depends on the system model. The channel with the longest initial heating phase should 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) of status display 8 is lit. When display is in Fahrenheit, the control system continues to use Celsius internally. This may result in up to one degree Fahrenheit being skipped.

3. Pressure Control

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

The parameters

PSL, PSH, PSP, PAH, PAL

and the display

Pcr

are available for pressure control. For a description of the parameters, refer to

Display Overview, Parameters and Values for Pressure Control

and

Parameter 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 common

relay output for overpressure alarm for all (maximum of six) drives. The pressure sensor measuring range can be modified with the

parameter

or with the selector switch on the analog module. If the pressure parameter values are no longer within the permissible (measuring) range after modification, the parameters are returned to the factory setting.

PAH = Pressure Monitoring for Overpressure (when Pressure Controlled)

PAL = Pressure Monitoring for Underpressure (when Pressure Controlled)

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, PAL

appears in display 30 (Fig. 1), and the red indication lamp setpoint = 2 bar, PAL = 3 bar), no underpressure alarm can be triggered (Refer to example).
