3 BASIC SAFETY
INSTRUCTIONS
These safety instructions do not make allowance for any
• contingencies and events which may arise during the installation,
operation and maintenance of the devices.
• local safety regulations – the operator is responsible for observing
these regulations, also with reference to the installation personnel.
DANGER!
Risk of injury from high pressure in the equipment/device.
▶Before working on equipment or device, switch off the pressure
and deaerate/drain lines.
Risk of electric shock.
▶Before working on equipment or device, switch off the power
supply and secure to prevent reactivation.
▶Observe applicable accident prevention and safety regulations
for electrical equipment.

Basic safety instructions
WARNING!
General hazardous situations.
To prevent injury, ensure that:
▶In the potentially explosion-risk area the Remote Sensor Type
8798 may be used only according to the specification on the
separate Ex type label. For use observe the additional instructions
enclosed with the device together with safety instructions for the
explosion-risk area.
▶Devices without a separate Ex type label may not be used in a
potentially explosive area.
▶Do not supply the medium connectors of the system with aggres-
sive or flammable media.
▶Do not supply the medium connectors with any liquids.
▶When unscrewing and screwing in the body casing or the trans-
parent cap, do not hold the actuator of the process valve but the
connection housing of Type 8798.
▶Do not physically stress the housing (e.g. by placing objects on
it or standing on it).
▶Do not make any external modifications to the device housings.
Do not paint the housing parts or screws.
▶The system cannot be activated unintentionally.
▶Installation and repair work may be carried out by authorized
technicians only and with the appropriate tools.
▶The device may be operated only when in perfect condition and
in consideration of the operating instructions.
▶After an interruption in the power supply or pneumatic supply,
ensure that the process is restarted in a defined or controlled
manner.
▶The general rules of technology apply to application planning
and operation of the device.
NOTE!
Electrostatic sensitive components / modules.
The device contains electronic components which react sensitively
to electrostatic discharge (ESD). Contact with electrostatically
charged persons or objects is hazardous to these components. In
the worst case scenario, they will be destroyed immediately or will
fail after start-up.
▶Observe the requirements in accordance with EN 61340-5-1 to
minimize or avoid the possibility of damage caused by sudden
electrostatic discharge.
▶Also ensure that you do not touch electronic components when
the power supply voltage is present.

5 SYSTEM DESCRIPTION
5.1 General description
The Remote Sensor Type 8798 is a digital non-contact position sensor
for use on pneumatically actuated variable speed drives. This Remote
Sensor is used in combination with the positioners (remote design)
Type 8791 and Type 8792/8793. The Remote Sensor cannot be used
as a stand-alone device. Its main task is to measure the position of a
pneumatically actuated control valve.
5.1.1 Features
Designs
The Remote Sensor is available as a linear and rotating position sensor
to be able to record the position of stroke and swivel actuators.
Position sensor
Robust, non-contact and wear-free position sensor that is connected
to the position controller via a circular line for supply and serial data
transmission.
Display
Display of operating modes via 2 LEDs.
