2 Safety

2.1 Intended use

The Autoclean CPC 20 / CPC 20 Z control sys-

tem is used to control the automatic cleaning

of pH electrodes. It can be connected to the

retractable assemblies CPA 463, CPA 463S

or CPA 465. The Ex version CPC 20 Z permits

operation in explosive atmospheres.

2.2 General safety notes

Warning:

Operation of the device in a manner

other than as described in these

operating instructions can lead to

unsafe and improper functioning of

the measuring system.

Installation, start-up, operation

The Autoclean CPC 20 / CPC 20 Z system

has been designed for safe operation accord-

ing to the state of the art in engineering and in

keeping with the applicable regulations and

EC directives; see »Technical data«.

However, if used improperly or other than for

the intended purpose, it may pose a hazard,

e.g. due to improper connection.

Installation, electrical connection, start-up,

operation and maintenance of the measuring

system must therefore be performed exclusi-

vely by trained specialists authorised by the

system operator. This personnel must have

read and understood these operating instructi-

ons and must adhere to them.

Immunity to interference

This device is protected against interference,

such as pulse-shaped transients, high fre-

quency and electrostatic discharges, accor-

ding to the applicable European standards.

This is only valid, however, for a device con-

nected according to the notes in these instal-

lation and operating instructions.

3 Description

3.1 System components

All system components are completely pre-wi-

red. The housing comes with Pg cable

glands, pneumatic connections and a vent

connection. Power, the CYR 10 injector, the

external control signals and the signal outputs

are connected to the terminal strip in the con-

trol cabinet.

The supply voltage for the non-Ex version is

230, 110 or 100 V AC or 24 V DC. All system

components are supplied with 24 V DC via

the built-in power supply unit.

The Ex version is supplied with power via the

CPM 152 measuring transmitter or via an in-

trinsically safe power supply.

Version C

The control system CPC 20-C (control via

program sequencer CYR 20) comprises:

• program sequencer CYR 20,

• pneumatic valves for assembly control,

• feedback devices (pneumatic or inductive),

• switches and keys for manual and automa-

tic operation, and

• LED operating status indicators.

Note:

The CPC 20-M / CPC 20Z-M can

only be controlled with the CPM 152

transmitter in conjunction with soft-

ware version 2.10 or later.

Version M

The control system CPC 20-M (control via

CPM 152 transmitter) comprises:

• pneumatic valves for assembly control, and

• feedback devices (pneumatic or inductive).

Version Z

The control system CPC 20 Z (control via

CPM 152 transmitter) comprises:

• pneumatic valves for assembly control, and

• feedback devices (pneumatic or inductive).
