Unintended Use

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:

and

, also refer to separate

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.

6. Control Panel for Double
Stream Pumps

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

Lo = Undertemperature Value/Interlock

The undertemperature locking device prevents the unit or system from being started up when the application material is too cold until the
temperature setpoint minus undertemperature value has been exceeded. On every initial heating, however, the locking device is not released
until the actual temperature is 3 °C (5.4 °F) below the temperature setpoint .
