Introduction
1. Introduction
The PG 674 is a small, handy device with a keyboard and two-
line display. It is used for operating the electronic cam control
units Posi Control KUAX 674 and KUAX 673. It is separated
from the cam control unit to allow variable use. It can be con-
nected with the cam control unit via the programming interface
at any time, even when the machine is running. This makes it
easy to check or modify the programs at the machine.

Introduction
The PG 674 is available in two designs:
Hand-held terminal
As a portable hand-held terminal it can easily be transported
and connected to the control device. The integrated buffered
memory allows you to load programs from one controller and
transfer them to another controller.
Built-in terminalAs a built-in terminal the device is firmly built into i.e. the
door of the switching cabinet and is thus permanently available
as an operating and display device.
The present operating manual exclusively describes the hard-
ware of the PG 674 and how you use it to operate controllers.
The control devices themselves are described elsewhere:

2.2. Reliability
Reliability of Kuhnke controllers is brought to the highest pos-
sible standards by extensive and cost-effective means in their
design and manufacture.
Amongst which are:
· selecting high-quality components,
· quality arrangements with our sub-suppliers,
· measures for the prevention of static charge during the hand-
ling of MOS circuits,
· Worst-Case dimensioning of all circuits,
· inspections during various stages of fabrication,
· computer aided tests of all assembly groups and their
coefficiency in the circuit,
· stress-test in raised ambient temperatures during 72 hours
realtime with nominal load on the outputs,
· statistic assessment of the quality of fabrication and of all re-
turned goods for immediate taking of adjustment measures.
Despite these measures, the occurrence of errors in electronic
control units - even if most highly improbable - must be taken
into consideration.

Reliability/Security
2.4. Security
Our product normally becomes part of larger systems or install-
ations. The following notes are intended to help integrating the
product into its environment without dangers for man or mate-
rial/equipment.
2.4.1. To be observed during project planning and installation
- 24V DC power supply:
· provide sufficient separation of low voltage,
· apply power packs in accordance with IEC 364-4-41 or
CENELEC HD 384.4.41 (VDE 0100, Part 410) respectively.
- In case of power breakdowns or power fades: the program has
to be structured in such a way as to create a defined state at
restart that excludes dangerous states.
- Emergency switches or other emergency installations have to
be realized in accordance with EN 60204/IEC 204
(VDE 0113). They have to be effective at any time.
- Safety and precautions regulations for qualified applications
have to be observed.
- Please pay particular attention to the notes of warning (→
2.3. Notes) which, at relevant places, will make you aware of
possible sources of errors.
- The relevent standards and VDE regulations are to be ob-
served in every case.
- Control elements have to be installed in such a way as to ex-
clude unintended operation.
- Control cables have to be layed in such a way as to exclude
interference (inductive or capacitive) which could influence
the operation of the controller.
Toachieveahighdegreeofconceptualsafetyinplanning
and installing an electronic controller it is essential to
follow the instructions given in the manual exactly be-
cause wrong handling could lead to rendering measures
against dangerous failures ineffective or to creating
additional dangers.

Reliability/Security
2.4.2. To be observed during maintenance and servicing
- During measuring and checking operations on a controller in
a power-up condition, precaution regulation VBG 4.0 has to
be observed and §8 (Admissible deviations during working on
parts) in particular.
- Repairs must only be executed by the trained Kuhnke person-
nel (usually in the main factory in Malente). Warranty ex-
pires in any other case.
- Spare parts:
Only use parts approved of by Kuhnke. Only genuine Kuhnke
modules must be used in modular controllers.
- Modules must only be connected to or disconnected from the
controller with no voltage supplied. Otherwise they may be
destroyed or (possibly not immediately recognizably!) de-
tracted from their proper functioning.
- Always deposit batteries and accumulators as special waste.
2.4.3. Measures for the prevention of electrostatic charge
Electrostatic charge is dangerous for components and assembly
groups. It is a peculiarity of electrostatics to not destroy the sen-
sitive components but to damage them in a not immediately
conceivable way. It is because of this that devices stop function-
ing after some time of service.
The ESD measures (ESD = electrostatic discharge) executed in
the factory are only guaranteed to be effective if they are also
regarded by the user (service).
Please note: - Only store parts in their factory-packing or in an antistatic
packing of similar quality.
- Assembly groups must only be touched by persons who are
grounded via a wrist bracelet and/or a discharging mat and
shoe-grounding strips ( observe protection of people!).
- Only ship assembly groups in their factory-packing or in an
antistatic packing of similar quality.

3. Design of the PG 674
The operating terminal PG 674 is used for programming the
cam control unit (see "4. The PG 674 as a programming de-
vice").
It can be supplied as a portable hand-held terminal and as a
built-in terminal.

The connecting cable is firmly attached to the hand-held termi-
nal. It serves both communication with the cam control unit and
supplying power to the hand-held terminal (24 V DC), which
are supplied by the cam control unit.

DC supply voltage is separately connected to a 2-pin screw-type
locking connector.
The built-in terminal is expected to be available as from
Version 2.0 in the spring of 1995.

The PG 674 as a programming device
4.1. General information on the operating terminal
The PG 674 is available both as a hand-held and built-in termi-
nal. Using the appropriate connecting cable, it is connected to
the „RS 232“ programming interface on the cam control unit.
The hand-held terminal is supplied via the cam control unit.
The built-in terminal must have a separate supply.
Both types of terminal basically take over 3 tasks:
- Programming
- Choosing a program
- Commissioning testing and monitoring machines
The display consists of 2 lines with 16 characters each. Four
pieces of information are permanently displayed in the standard
display:
- Current program number
- Encoder position
- Encoder speed
- Output number
The key pad consists of 25 keys, 7 of which have a double func-
tion. The keyboard has been labelled for international use,
partly with symbols. These symbols are also briefly described on
the terminal.
The operating terminal has its own memory which is protected
agains data loss by an accu. This memory has the program
number 32 and is suitable for copying programs from one cam
control unit to another.
-This instruction manual already describes how to handle
operating terminals with version 2.0 which are expected
to be available as from the spring of 1995.
-This instruction manual is also valid for the operating
terminals with version numbers < 2.0 although there are
marginal differences in the display and keyboard label-
ling. These are fairly obvious, however. The handling of
the device corresponds to that described in instruction
manual E 293 GB for the KUAX 673, .
-The differences result from the further development and
standardizing of the operating terminals.
