3. INSTALLATION
3.1. LOCATION
The MultiStop control unit is designed for panel mounting applications and should be mounted in a
convenient position for an operator to see the displays and be able to easily enter program
information into the unit.
Take care to prevent liquids and swarf from entering the enclosure and hence the MultiStop case.
For free standing applications a small enclosure should be used. It conveniently fits into many
standard enclosures, for example the European manufacturer “Rittal” enclosure part number
AE1031 (380 x 300 x 210) would easily house MultiStop and a row of connectors.
3.2. SAFETY
Mains voltages are present inside MultiStop and can cause severe electric shock. If it is necessary
to remove the cover of the MultiStop, it must be disconnected from the mains supply before work
on it is carried out.
A good earth cable must be attached to the MultiStop and its impedance must conform to the
requirements of local industrial safety regulations and should be inspected and tested at
appropriate regular intervals.
3.3. THE MULTISTOP POWER SUPPLY
The MultiStop unit should be connected to a clean 100-230 (+10% - 15%) VAC 50/60 Hz supply.
This supply should not be shared with other electrically noisy equipment. Filtering should be
provided if required.
3.4. OUTPUT CONNECTIONS
Weidmuler BL3.5 / 8 (order number 159742) plugs are used for output connections
Wire the control inputs in accordance with the details in this section.
Banks X, Y and A (pins 9 - 16) have polarising pins at positions 2 and 7 on the plug.
Bank B (pins 9 - 16) has polarising pins at positions 1 and 7 on the plug.
Bank B (pins 1 - 8) has polarising pins at positions 2 and 8 on the plug.
DO NOT MAKE OR BREAK CONNECTIONS WITH THE POWER ON.
An external supply is required to power the output lines. If a DC load is being driven then a 24V DC
(absolute max. 25V DC) supply of suitable capacity should be connected to the external supply pin
see.
If the MultiStop has the relay option fitted the power consumption of the relay output stage is 8 mA
per relay. This requirement should be added to your switching needs to achieve a minimum overall
24V DC power requirement..
A typical output stage is shown below,

MultiStop Plus Technical Specification
Goodwin Electronics Ltd D1009 / V1.740 / 13/07/11 Page 12
The external 24 V (absolute max. 25V) DC supply is common to all outputs. Each output can
source 50 ma. Connect the 0V of the external DC supply to pin 8 of Group B (0V digital) to provide
protection against inductive loads.
A relay output stage is shown below:
The external 24 V DC supply powers all internal relays. The example above shows a common 24 V
DC supply powering internal relays and external loads. If required the relay contacts can switch
other supplies up to the above rating.
Output functions can be assigned to any pin on the connectors using the Parameter Configuration
mode, or they can be turned off so they do not function. From the factory the unit is defaulted to the

4.1. INPUT SETUP
Each of the following input functions can be assigned to any of the 24 input pins available. The
default configuration and descriptions of the functions are given in section 3.5.
From the engineering window each input can be configured to asserted either as a level or a an
edge,
ie., asserted when HI

To assign inputs to pins other than the defaults, each pin is given a reference number ranging from
1 to 24 which defines the I/O groups X, Y and A on the rear panel of the MultiStop unit.
Inputs 1 to 8 are on pins 1 - 8 on Group Y.
Inputs 9 to 16 are on pins 1 - 8 on Group X.
Inputs 17 to 24 are on pins 1 - 8 on Group A.
Any input function can be disabled by assigning the number 0 to it. For example, the end stop
inputs may not be relevant on a continuously indexing machine. By assigning 0 to them it means
that they do not have to be connected to +24V for normal operation.
Enter INPUT SETUP window as described above and select the input you wish to reassign, then
press ENTER to select it followed by the input pin number you require. Press ENTER again to
confirm the assignment.
Press ESC to exit this window.
4.2. OUTPUT SETUP
From the engineering window the asserted state of each output can be defined and the format
used is (taking Enable X as an example)
Output # Enable X 1
Enable X asserted LOW
This results in the X axis output 1 is set to 0 volts a whenever the program enables the X axis.
Each of the following output functions can be assigned to any of the 24 output pins available. The
default configuration and descriptions of the functions are given in section 3.5.1
Enable X
X inposition disable if unit is configured as an indexer
Enable YY inposition disable if unit is configured as an indexer
Datum set
Auxiliary (1 to 8 inclusive)
Auxiliary reset type (1 to 8 inclusive)
To assign outputs to pins other than the defaults, each pin is given a reference number ranging
from 1 to 24 which defines the I/O groups X, Y and A on the rear panel of the MultiStop unit.
Outputs 1 to 8 are on pins 9 -16 on Group Y.
Outputs 9 to 16 are on pins 9 -16 on Group X.
Outputs 16 to 24 are on pins 9 -16 on Group A.
Enter OUTPUT SETUP window as described above and select the output you wish to reassign,
then press ENTER to select it followed by the pin number you require. Press ENTER again to
confirm the assignment.
Any auxiliary outputs which have been set will reset by default when a PowerTalk program has
been stopped or terminates naturally. However, if an auxiliary output is required to remain asserted
after a program has stopped, it can be configured to do so by selecting the appropriate ‘Auxiliary
reset type’ for the output. The reset types available to the user are ‘LEAVE’ (leaving any set
auxiliary asserted after program termination) and ‘RESET’ (forcing the auxiliary to be
unconditionally reset after program termination).

5. MACHINE SETUP
This window allows the user to define certain machine parameters that configures the MultiStop to
the application the X axis to be setup in the appropriate manner and the other the Y axis.
5.1. AXES TYPE
Options: Linear or Angular
Setting Method: Select Axes Type from the system parameter list and press ENTER. Use
the UP or DOWN arrow keys to select the required option from the list
provided on the screen. Press ENTER to accept the highlighted value and
to return to the main system parameter list.
Application Notes: If the angular option is selected then the axis position will overflow at 360
degrees to 0 and underflows at values below zero to 359. As the position
over/ under flows a revolution counter is incremented or decremented. The
value of the rev counter will be displayed in the AUTO window.
Default Setting: X axis: Linear
Y axis: Linear
Your Setting: X axis:
Y axis:
Also see: Counts per revolution
Scale Factor

5.2. AXIS MODULUS (ENGINEERING WINDOW ONLY)
Options: 0 to 360.000
Setting Method: Select AXIS TYPE from the system parameter list and press ENTER. Enter
a numeric value in the option range. Press ENTER to accept the value and
to return to the main system parameter list.
Application Notes: This parameter is only used if the angular option is chosen. The controller
will reset the axis to zero whenever the position is greater than the
modulus value. Also whenever the axis position goes negative the
displayed position is reset to the modulus value. A revolution counter
keeps track of each of the underflow and overflow events.
Default Setting: X axis: 360.000
Y axis: 360.000
Your Setting: X axis:
